Background: Balancing training load helps prevent injury and maximize performance, but coaches do not often know the load or intensity of drills when making selections for practice. Objective: This study aimed to classify the drills of a women’s collegiate lacrosse team into low, moderate, and high intensity categories. Methods: Twenty-five participants wore global positioning system (GPS) devices and heart rate (HR) monitors daily during team practice and scrimmage matches. The data collected was trimmed to reflect only the time the players practiced and then organized by drill. Mean HR, distance rate, and training impulse (TRIMP) scores were used to classify drills into tertiles: low, moderate, and high intensity. Results: A total of 56 unique drills were analyzed over 33 training days, with 24 drills considered moderate intensity, 17 drills were high intensity, and 15 drills were low intensity. By position, 17 drills were low intensity for the midfielders, followed by 16 for the attacker, and 12 for the defenders and goalies. The defenders had the highest number of moderate intensity drills with 27, followed by the attackers with 24, midfielders with 21, and goalies with 17. Lastly, midfielders and goalies had the highest number of high intensity drills with 18, followed by attackers with 17, and defenders with 16. Conclusions: These results will help the coaching and training staff manage workloads and potentially reduce risk of injury and overtraining by giving insight into the demands of each drill they require of their athletes.

Full textAbstract:
Soccer players perform a variety of training drills to develop the physical, technical and tactical qualities required for match-play. The role of coaches in prescribing training suggests that players may not always meet physical targets set by conditioning staff. To quantify the physical outputs elicited by different training drill types, 183 professional soccer players were monitored over 8 seasons using Microelectromechanical Systems during normal training, yielding 65,825 drill observations [362 ± 341 observations·player−1]. Linear mixed models assessed the influence of drill type, head coach and playing position on physical output. Drills lasted ~14 min, eliciting total distances and high speed running of ~1000 m and 40 m, respectively. Conditioning drills elicited substantially greater relative high-speed running [18.8 ± 27.2 m.min−1] and Sprint [3.5 ± 9.4 m.min−1] distances than all other drill types. The proportion of training drill types used and external outputs elicited per drill were affected by the head coach. Midfielders recorded the highest total distance [77.3 ± 36.1 m.min] and PlayerLoad™ [8.29 ± 3.54] of any playing position, whilst the lowest outputs were recorded by goalkeepers. This study provides reference data for practitioners when seeking to manipulate training prescription to achieve physical output targets whilst also meeting the team’s technical and tactical objectives.

The main purpose of this study was to develop a model for predicting the quality of holes drilled in the root part of the spar of helicopter main rotor blades made of glass fiber-reinforced plastic (GFRP)-Ti multilayer polymer composite. As the main quality criterion, delaminations at the entry and exit of the drill from the hole were taken. In the experimental study, a conventional drill and two modified geometry drills, a double-point angle drill and a dagger drill, were used. Preliminary experiments showed the best hole quality when using modified drills, which allowed further detailed study only with both modified drills at different drilling speeds and feed rates. Its results in the form of training sets were used to build artificial neural networks (ANNs) to predict delamination at the entry and exit of the drilled holes. An analysis of the fitted response functions presented as 3D surface plots and contour plots led to the selection of the best tool, a double-point angle drill, which demonstrated the lowest achievable delamination both at the entry and at the exit of the holes approximately 1.5 times less (0.45/0.48 mm) compared to dagger drills (0.68/0.7 mm) and determined the ~5 times larger optimal area for the drilling speed and feed rate. The results obtained confirm the possibility of effective prediction of the quality and productivity of mechanically processed composites of complex reinforcement using ANN to quantify the quality criteria and search for the optimal modes of such technologies.

The purpose of this research was to determine the potential training effect of reactive agility in improving speed and agility. This study was conducted on 36 students and divided into 3 groups with 12 students per groups. Group 1 was given lateral mirror drill, Group 2 sprint mirror drill, and Group 3 conventional training for a period of 8 weeks, 3 times/week with a day off. Performance measures of agility and speed were assessed via the T-test for agility and 30m sprints for speed, respectively. Data was analyzed using paired sample t-test and multivariate analysis of variance. The result of this study found that there was a significant effect of sprint mirror drill to improve speed and agility; there was a significant effect of lateral mirror drill in improving speed and agility; there was a difference effect of lateral mirror drill and sprint mirror drills in improving speed and agility. Conclusion: these data provide preliminary support of incorporating reactive agility drills such as the sprint mirror and lateral mirror drills in improving performance measures of speed and agility.

Purpose: To statistically evaluate the internal and external load metrics in different types of lacrosse drills. Methods: A total of 25 Division I collegiate female lacrosse players wore a heart rate monitor and a global positioning system during preseason training sessions. Seven measures determined training load, 2 internal measures and 5 external measures, across 5 different types of drills: stickwork, small-sided games, individual skills, conditioning, and team drills. Principal component analysis was used to determine which internal and external load variables were most associated with each drill type. Results: Stickwork extracted 2 principal components, explaining 45% and 17% of the variance. Small-sided games extracted 1 principal component, explaining 51% of the variance. Individual skills extracted 2 components, explaining 39% and 22% of the variance. Conditioning extracted 2 components, explaining 44% and 24% of the variance. Team drills extracted 2 components, explaining 52% and 18% of the variance. Conclusions: In 4 out of 5 training modes, the inclusion of both internal and external training-load measures was necessary to accurately decipher training load. For most drills, the first component is related to measures of external load, and the second component described the balance between internal and external load measures. Small-sided games extracted only external measures including the following: accelerations, total distance, and average speed. These results show that a combination of internal and external load measures is required to determine training load during certain training modes. This information can help coaches make decisions about desired training load for practice sessions.

Purpose:Planning tennis sessions accentuating physical development requires an understanding of training load (TL). The aims were to describe the external and internal TL of drills and analyze relationships between ratings of perceived exertion (RPE), TL, and other measures.Methods:Fourteen elite-level junior tennis athletes completed 259 individual drills. Six coaches helped devise classifications for all drills: recovery/defensive, open pattern, accuracy, 2-on-1 open, 2-on-1 net play, closed technical, point play, and match play. Notational analysis on stroke and error rates was performed postsession. Drill RPE and mental exertion were collected postdrill, while heart rate (HR) was recorded continuously.Results:Recovery/defensive, open pattern, and point play were significantly greater than closed technical drills (P < .05) for RPE and mental exertion, as were accuracy drills and match play (P < .05). Recovery/defensive, open-pattern, accuracy, and 2-on-1 open drills had higher stroke rates than match play (P < .05). Error rates of closed technical drills were significantly higher than for open pattern, 2-on-1 drills, point play, and match play (P < .05). No HR differences were observed (P > .05) between categories. Substantial correlations existed for drill RPE and TL with mental exertion (r > .62) for several categories. TL was substantially correlated with total strokes (r > .65), while HR and stroke and error rates were in slight to moderate agreement with RPE and TL (r < .51).Conclusions:Recovery/defensive drills are highest in physiological stress, making them ideal for maximizing physicality. Recovery/defensive drills compromised training quality, eliciting high error rates. In contrast, 2-on-1 net-play drills provided the lowest error rates, potentially appropriate for error-amelioration practice. Open-pattern drills were characterized by significantly higher stroke rates, suggesting congruence with high-repetition practice. Finally, with strong relationships between physical and mental perception, mental exertion may complement currently used monitoring strategies (TL and RPE).

Introduction: Disaster drills are a valuable means of training healthcare providers to respond to mass casualty incidents resulting from acts of terrorism or public health crises. We present here a proposed hospital-based disaster drill evaluation tool that is designed to identify strengths and weaknesses of hospital disaster drill response, provide a learning opportunity for disaster drill participants, and promote integration of lessons learned into future responses. Methods: Clinical specialists, experienced disaster drill coordinators and evaluators, and experts in questionnaire design developed the evaluation mod-ules based upon a comprehensive review of the litera-ture, including evaluations of disaster drills. The tool comprises six evaluation modules designed to capture strengths and weaknesses of different aspects of hospital disaster response. The Predrill Module is completed by the hospital during drill planning and is used to define the scope of the exercise. The Incident Command Center Module assesses command structure, communication between response areas and the command center, and communication to outside agencies. The Triage Zone Module captures the effect of a physical space on triage activities, efficiency of triage operations, and victim flow. The Treatment Zone Module assesses the relation of the zone’s physical characteristics to treatment activities, efficacy of treatment operations, adequacy of supplies, and victim flow. A Decontamination Zone Module is available for evaluating decontamination operations and the use of decontamination and/or personal protective equipment in drills that involve biological or radiological hazardous materials. The Group Debriefing Module provides sample discussion points for drill participants in all types of drills. The tool also has addenda to evaluate specifics for 1) general observation and documentation, 2) victim tracking, 3) biological incidents, and 4) radiological incidents. Conclusion: This evaluation tool will help meet the need for standardized evaluation of disaster drills. The modular approach offers flexibility and could be used by hospitals to evaluate staff training on response to natural or man-made disasters.

The mathematical model was developed for predicting the influence of the drill point angles on the cutting forces in drilling with the twist drills, which was used to optimize those angles for reducing drilling forces. The approach was based on multigene genetic programming, for the training data, the grinding tests of twist drill were firstly conducted for the different drill point angles in Biglide parallel machine, and then drilling tests were performed on carbon fiber reinforced plastics using the grinded drills. The effectiveness of the proposed approach was verified through comparing with published data. It was found that the proposed model agreed well with the experimental data and was useful for improving the performance of twist drill.

AbstractIntroduction:Recently, mass-casualty incident (MCI) preparedness and training has received increasing attention at the hospital level.Objectives:To review the existing evidence on the effectiveness of disaster drills, technology-based interventions and tabletop exercises in training hospital staff to respond to an MCI.Methods:A systematic, evidence-based process was conducted incorporating expert panel input and a literature review with the key terms: “mass casualty”, “disaster”, “disaster planning”, and “drill”. Paired investigators reviewed citation abstracts to identify articles that included evaluation of disaster training for hospital staff. Data were abstracted from the studies (e.g., MCI type, training intervention, staff targeted, objectives, evaluation methods, and results). Study quality was reviewed using standardized criteria.Results:Of 243 potentially relevant citations, twenty-one met the defined criteria. Studies varied in terms of targeted staff, learning objectives, outcomes, and evaluation methods. Most were characterized by significant limitations in design and evaluation methods. Seventeen addressed the effectiveness of disaster drills in training hospital staff in responding to an MCI, four addressed technology-based interventions, and none addressed tabletop exercises. The existing evidence suggests that hospital disaster drills are effective in allowing hospital employees to become familiar with disaster procedures, identify problems in different components of response (e.g., incident command, communications, triage, patient flow, materials and resources, and security) and provide the opportunity to apply lessons learned to disaster response. The strength of evidence on other training methods is insufficient to draw valid recommendations.Conclusions:Current evidence on the effectiveness of MCI training for hospital staff is limited. A number of studies suggest that disaster drills can be effective in training hospital staff. However, more attention should be directed to evaluating the effectiveness of disaster training activities in a scientifically rigorous manner.

Purpose: To examine the speed profiles of elite wheelchair rugby (WCR) players during game-simulation training drills of differing player number and shot-clock regulations. A secondary aim was to determine whether the profiles were further influenced by player classification. Methods: Eight elite WCR players (low-point n = 3, high-point n = 5) were monitored using a radio-frequency-based indoor tracking system during training sessions over a 5-mo period. Speed profiles were collected for 3 modified game-simulation drills—3-versus-3 drills (n = 8 observations), 30-s shot clock (n = 24 observations), and 15-s shot clock (n = 16 observations)—and were compared with regular game-simulation drills (4 vs 4, 40-s shot clock; n = 16 observations). Measures included mean and peak speed; exercise-intensity ratios, defined as the ratio of time spent performing at high and low speeds; and the number of high-speed activities performed. Results: Compared with regular game-simulation drills, 3-versus-3 drills elicited a moderate increase in mean speed (6.3%; effect size [ES] = 0.7) and the number of high-speed activities performed (44.1%; ES = 1.1). Minimal changes in speed profiles were observed during the 30-s shot clock, although moderate to large increases in all measures were observed during the 15-s shot-clock drills. Classification-specific differences were further identified, with increased activity observed for high-point players during the 3-versus-3 drill and for low-point players during the 15-s shot clock. Conclusion: By reducing the number of players on court and the shot clock to 15 s, coaches can significantly increase elite WCR players’ speed profiles during game-simulation drills.

Purpose:To compare the effects of combining high-intensity training (HIT) and sport-specific drill training (MT) versus sportspecific drill training alone (DT) on fitness performance characteristics in young tennis players.Methods:Twenty young tennis players (14.8 ± 0.1 y) were assigned to either DT (n = 10) or MT (n = 10) for 8 wk. Tennis drills consisted of two 16- to 22-min on-court exercise sessions separated by 3 min of passive rest, while MT consisted of 1 sport-specific DT session and 1 HIT session, using 16–22 min of runs at intensities (90–95%) related to the velocity obtained in the 30–15 Intermittent Fitness Test (VIFT) separated by 3 min of passive rest. Pre- and posttests included peak oxygen uptake (VO2peak), VIFT, speed (20 m, with 5- and 10-m splits), 505 Agility Test, and countermovement jump (CMJ).Results:There were significant improvements after the training period in VO2peak (DT 2.4%, ES = moderate; MT 4.2%, ES = large) and VIFT (DT 2.2%, ES = small; MT 6.3%, ES = large) for both DT and MT, with no differences between training protocols. Results also showed a large increase in the 505 Agility Test after MT, while no changes were reported in the other tests (sprint and CMJ), either for MT or DT.Conclusions:Even though both training programs resulted in significant improvements in aerobic performance, a mixed program combining tennis drills and runs based on the VIFT led to greater gains and should be considered the preferred training method for improving aerobic power in young athletes.

Purpose: To determine the relationship between drill type and accelerometer-derived loads during various team-sport activities and examine the influence of unit fitting on these loads. Methods: Sixteen rugby league players were fitted with microtechnology devices in either manufacturer vests or playing jerseys before completing standardized running, agility, and tackling drills. Two-dimensional (2D) and 3-dimensional (3D) accelerometer loads (BodyLoad™) per kilometer were compared across drills and fittings (ie, vest and jersey). Results: When fitted in a vest, 2D BodyLoad was higher during tackling (21.5 [14.8] AU/km) than during running (9.5 [2.5] AU/km) and agility (10.3 [2.7] AU/km). Jersey fitting resulted in more than 2-fold higher BodyLoad during running (2D = 9.5 [2.7] vs 29.3 [14.8] AU/km, 3D = 48.5 [14.8] vs 111.5 [45.4] AU/km) and agility (2D = 10.3 [2.7] vs 21.0 [8.1] AU/km, 3D = 40.4 [13.6] vs 77.7 [26.8] AU/km) compared with a vest fitting. Jersey fitting also produced higher BodyLoad during tackling drills (2D = 21.5 [14.8] vs 27.8 [18.6] AU/km, 3D = 42.0 [21.4] vs 63.2 [33.1] AU/km). Conclusions: This study provides evidence supporting the construct validity of 2D BodyLoad for assessing collision/tackling load in rugby league training drills. Conversely, the large values obtained from 3D BodyLoad (which includes the vertical load vector) appear to mask small increases in load during tackling drills, rendering 3D BodyLoad insensitive to changes in contact load. Unit fitting has a large influence on accumulated accelerometer loads during all drills, which is likely related to greater incidental unit movement when units are fitted in jerseys. Therefore, it is recommended that athletes wear microtechnology units in manufacturer-provided vests to provide valid and reliable information.

The purpose of study was to find out the effect of circuit training combined with speed agility quickness drills and jump rope drills on agility. To achieve the purpose of the study, thirty school boys from different schools from of Alagappa Sports Foundation at Karaikudi, were selected as subject at random. Their age group range between 11 to 14 years. The study was formulated as pre and post test random group design, in which thirty subject were divided into three equal groups. The experimental group-1 (n=10, CT-SAQD) underwent circuit training combined with speed agility, and quickness drills, the experimental group-2 (n=10, CT-JRD) underwent through circuit training combined with Jump Rope Drills and group 3 served as a control group (n=10, CG) did not undergo any specific training. In this study, two training programme were adopted as independent variable, i.e., circuit training combined with speed agility quickens and circuit training combined with jump rope drills. The agility was selected as dependent variable. It was measured by T test in seconds. The selected two treatment groups were performed five days in a week for the period of six weeks, as per the stipulated training program. The data was collected before and after the training period. The collected pre and post data was critically analyzed with apt statistical tool of analysis of co-variance, for observed the significant adjusted post-test mean difference of three groups. The Scheffe’s post hoc test was used to find out pair-wise comparisons between groups. To test the hypothesis 0.05 level of significant was fixed. The performance of the agility better in circuit training combined with the drills of speed, agility and quickness than the circuit training combined with the drills of jump rope.

The purpose of study was to find out the effect of two modes of circuit training on muscular endurance in term of upper body of school boys. To achieve the purpose of the study, thirty school boys from different schools from of Alagappa Sports Foundation at Karaikudi, were selected as subject at random. Their age group range between 11 to 14 years. The study was formulated as pre and post test random group design, in which thirty subject were divided into three equal groups. The experimental group-1 (n=10, CT-SAD) underwent circuit training combined with speed agility quickness drills, the experimental group-2 (n=10, CT-JRD) underwent through circuit training combined with Jump Rope Drills and group 3 served as a control group (n=10, CG) did not undergo any specific training. In this study, two training programme were adopted as independent variable, i.e., circuit training combined with speed agility quickens and circuit training combined with jump rope drills. The physical fitness variable muscular endurance in term of upper body was selected as dependent variable. It was measured by push-up measured in counts. The selected two treatment groups namely circuit training combined with speed agility quickens drills and circuit training combined with jump rope drills were performed five days in a week for the period of six weeks, as per the stipulated training program. The muscular endurance in term of upper body was collected before and after the training period. The collected pre and post test data was critically analyzed with apt statistical tool of analysis of co-variance, for observed the significant adjusted post-test mean difference of three groups. The Scheffe’s post hoc test was used to find out pair-wise comparisons between groups. To test the hypothesis 0.05 level of significant was fixed. The performance of the muscular endurance in term of upper body is similar in circuit training combined with the jump rope drills and the circuit training combined with speed agility and quickness drills.

Full textAbstract:
This study assessed the influence of exercise prescription on the objectively measured exercise dose in basketball. Intensity (RPE) and volume (sRPE) were prescribed by a professional coach on a drill-by-drill basis during pre-season training for nine elite basketball players. Training drills were classified by prescribed intensity (easy-moderate, moderate-hard, hard–very hard, and very hard-maximal) and type (warm-up, skill-development, offensive- and defensive-technical/tactical, or match-simulation). Exercise intensity was objectively quantified using accelerometry-derived average net force (AvFNet) and time spent in accelerometry-derived relative intensity zones. The volume of exercise (exercise dose) was objectively quantified using accumulated impulse (AvFNet × duration). Relationships between prescribed volume and exercise dose were explored by correlations between sRPE and drill-by-drill accumulation of sRPE (dRPE) with impulse. Very hard-maximal drill intensity was greater than hard-very hard (p = 0.011), but not moderate-hard (p = 0.945). Very hard-maximal drills included the most time performing Supra-maximal intensity (>100% V ˙ O2R) efforts (p < 0.001), suggesting that intensity prescription was based upon the amount of high-intensity exercise. Correlations between impulse with sRPE and dRPE were moderate (r = 0.401, p = 0.197) and very-large (r = 0.807, p = 0.002), respectively, demonstrating that the coach misinterpreted the accumulative effect of drill volume over an entire training session. Overall, a mismatch existed between exercise prescription and exercise dose. Objective monitoring might assist coaches to improve precision of exercise prescription.

ABSTRACTWe examined the response of 11 Los Angeles County (LAC) hospitals designated as Disaster Resource Centers (DRCs) to a statewide, earthquake preparedness drill, LAC's most comprehensive earthquake disaster drill to date. Semistructured interviews were conducted with the coordinators of 11 of the 14 LAC DRCs within 3 weeks of the drill. Interviews were transcribed and thematic analysis was supported by analytical software (Atlas.ti). Except for one pediatric specialty DRC, most DRCs did little to fully test their institutions' capacity to manage pediatric patients. Few DRCs included children as mock victims. Little or no attention was focused on pediatric triage and other pediatric clinical, psychosocial, and resource issues. Respondents maintained that community readiness is hampered by compartmentalizing the preparedness planning, training, and drilling. Without a mandate to coordinate with other agencies, few DRCs reported coordination with other community entities. Those that did were in smaller submunicipalities within LAC. Community coordination is critical to effective response to disasters, yet disaster preparedness planning and drills are most often uncoordinated and compartmentalized. Drills and training need to be transdisciplinary and coordinated with other community entities likely to play a role in pediatric disaster management.(Disaster Med Public Health Preparedness. 2012;6:182–186)

Purpose:To characterize the physical and physiological responses during different basketball practice drills and games.Methods:Male basketball players (n = 11; 19.1 ± 2.1 y, 1.91 ± 0.09 m, 87.9 ± 15.1 kg; mean ± SD) completed offensive and defensive practice drills, half court 5on5 scrimmage play, and competitive games. Heart rate, VO2 and triaxial accelerometer data (physical demand) were normalized for individual participation time. Data were log-transformed and differences between drills and games standardized for interpretation of magnitudes and reported with the effect size (ES) statistic.Results:There was no substantial difference in the physical or physiological variables between offensive and defensive drills; physical load (9.5%; 90% confidence limits ±45); mean heart rate (-2.4%; ±4.2); peak heart rate (-0.9%; ±3.4); and VO2 (–5.7%; ±9.1). Physical load was moderately greater in game play compared with a 5on5 scrimmage (85.2%; ±40.5); with a higher mean heart rate (12.4%; ±5.4). The oxygen demand for live play was substantially larger than 5on5 (30.6%; ±15.6).Conclusions:Defensive and offensive drills during basketball practice have similar physiological responses and physical demand. Live play is substantially more demanding than a 5on5 scrimmage in both physical and physiological attributes. Accelerometers and predicted oxygen cost from heart rate monitoring systems are useful for differentiating the practice and competition demands of basketball.

Full textAbstract:
Background:Uganda is prone to viral hemorrhagic fever (VHF) outbreaks. Infection prevention and control capacity is critical to supporting patient care, to preventing nosocomial transmission to health workers, and to limiting spread within the community. Offsite didactic training may increase healthcare worker knowledge, but this approach may be inadequate for assuring confident execution of practical clinical tasks in patient care settings. We aimed to develop a competency-based, onsite mentorship model for sentinel case isolation and management of viral hemorrhagic fever syndromes in Uganda. Methods: The Naguru Regional Referral Hospital (China Uganda Friendship Hospital) Kampala was selected as a site for training after its designation by the Uganda Ministry of Health (MoH) as facility for isolation of healthcare workers with suspected or confirmed VHF. The need for mentorships was determined from information from training providers, MoH assessments, hospital management, and key hospital staff. A list of skills was developed by reviewing WHO case management guidelines and Uganda-approved VHF trainings. The skills, exercised using scenario-based drills, focused on safety practices, identification and isolation of suspect cases, and delivery of optimized clinical care to suspected cases of VHF, among others. Trained facilitators (n = 2–4) supervised drills attended by staff from Naguru and other Kampala-based health facilities. Drills were scheduled weekly and were ordered to progressively increase in complexity. Specific drills could be repeated at the subsequent mentorship visit if gaps were identified. Results: Over 3 months, 12 drills were completed (Table 1). Cadres trained included 10 medical doctors, 12 nurses, 3 clinical officers, 5 laboratory technicians, 6 hygienists, 2 security officers, and 3 administrative officers. On average, 8 hospital staff attended weekly drills. During 3 months of the intervention, 1 suspected case of VHF and 3 cases with laboratory confirmed cholera were managed by the hospital team, and staff demonstrated the capacity for safe handling of patients with infectious bodily fluids. Barriers encountered included practice fatigue from repeated drills, challenges with team cohesion since members were from different institutions, limited personal protective equipment for repeated trainings, and competing routine hospital activities that reduced numbers of staff available for training. Repeated drills included clinical management, cadaver management, and infectious spills. Conclusions: This onsite mentorship project supported healthcare workers to gain confidence in the management of suspected VHF infection and other highly infectious diseases. Continued mentorship, hospital administration support and increase in exercise complexity are needed to consolidate on these gains.Funding: NoneDisclosures: Mohammed Lamorde reports contract research for Janssen Pharmaceutica, ViiV, and Mylan.

Purpose:To investigate the speed profiles of individual training modes in comparison with wheelchair rugby (WCR) competition across player classifications.Methods:Speed profiles of 15 international WCR players were determined using a radio-frequency-based indoor tracking system. Mean and peak speed (m/s), work:rest ratios, and the relative time spent in (%) and number of high-speed activities performed were measured across training sessions (n = 464) and international competition (n = 34). Training was classified into 1 of 4 modes: conditioning (n = 71), skill-based (n = 133), game-related (n = 151), and game-simulation drills (n = 109). Game-simulation drills were further categorized by the structured duration, which were 3-min game clock (n = 44), 8-min game clock (n = 39), and 10-min running clock (n = 26). Players were grouped by their International Wheelchair Rugby Federation classification as either low-point (≤1.5; n = 8) or high-point players (≥2.0; n = 7).Results:Conditioning drills were shown to exceed the demands of competition, irrespective of classification (P ≤ .005; effect size [ES] = 0.6–2.0). Skill-based and game-related drills underrepresented the speed profiles of competition (P ≤ .005; ES = 0.5–1.1). Mean speed and work:rest ratios were significantly lower during 3- and 8-min game-simulation drills in relation to competition (P ≤ .039; ES = 0.5–0.7). However, no significant differences were identified between the 10-min running clock and competition.Conclusions:Although game-simulation drills provided the closest representation of competition, the structured duration appeared important since the 10-min running clock increased training specificity. Coaches can therefore modify the desired training response by making subtle changes to the format of game-simulation drills.

This paper presents the progress recorded during the technical-tactical drills after applying the operational objective-based athletic training programme on the junior II male handball players at the Bacau School Sports Club. The purpose of this research was to test the subjects throughout the competition season by applying a series of technical-tactical tests. It was presumed that after applying the operational objective-based athletic training programme in the junior II male handball players, progress in the technical-tactical drills would be ascending, recording superior final results, these being conditioned by an optimal training programmme. Data were gathered from three control drills and from the assessment of the players’ actions during the game. Generally, an uneven evolution was noticed, with some stagnation, and even some regress in certain parts, but with an obvious progress in the final tests, in all drills and regarding the assessment of the players’ actions during the game.

Purpose:High-performance tennis environments aim to prepare athletes for competitive demands through simulated-match scenarios and drills. With a dearth of direct comparisons between training and tournament demands, the current investigation compared the perceptual and technical characteristics of training drills, simulated match play, and tournament matches.Methods:Data were collected from 18 high-performance junior tennis players (gender: 10 male, 8 female; age 16 ± 1.1 y) during 6 ± 2 drill-based training sessions, 5 ± 2 simulated match-play sessions, and 5 ± 3 tournament matches from each participant. Tournament matches were further distinguished by win or loss and against seeded or nonseeded opponents. Notational analysis of stroke and error rates, winners, and serves, along with rating of perceived physical exertion (RPE) and mental exertion was measured postsession.Results:Repeated-measures analyses of variance and effect-size analysis revealed that training sessions were significantly shorter in duration than tournament matches (P < .05, d = 1.18). RPEs during training and simulated matchplay sessions were lower than in tournaments (P > .05; d = 1.26, d = 1.05, respectively). Mental exertion in training was lower than in both simulated match play and tournaments (P > .05; d = 1.10, d = 0.86, respectively). Stroke rates during tournaments exceeded those observed in training (P < .05, d = 3.41) and simulated-match-play (P < .05, d = 1.22) sessions. Furthermore, the serve was used more during tournaments than simulated match play (P < .05, d = 4.28), while errors and winners were similar independent of setting (P > .05, d < 0.80).Conclusions:Training in the form of drills or simulated match play appeared to inadequately replicate tournament demands in this cohort of players. Coaches should be mindful of match demands to best prescribe sessions of relevant duration, as well as internal (RPE) and technical (stroke rate) load, to aid tournament preparation.

ABSTRACT Sun Transport, the Marine division of Sun Refining and Marketing Company, a subsidiary of Sun Company, Inc., has conducted a series of drills to assess the effectiveness of its Oil Spill Response Plan. The latest drill, third in the series, was conducted in September 1982. Papers presented at the 1979, 1981, and 1983 Oil Spill Conference describe the plan, its rationale, and the previous two drills. This paper reviews the training progression of the previous exercises and reports on the findings and experiences of this latest exercise. As in previous drills, the planning committee and a few others were the only people in Sun Company with any prior knowledge of the drill. This simulation was the most extensive. It involved simultaneous and separate call-out scenarios, full-scale use of contractor cleanup crew and equipment, chartering aircraft, and participation by representatives of the Clean Caribbean Cooperative, the Tanker Owners Voluntary Agreement Concerning Liability for Oil Pollution (TOVALOP), and the U.S. Coast Guard. The realism provided by this exercise allowed each participant to experience firsthand the problems on-scene at a major cleanup operation and to come away with confidence in managing them.

Full textAbstract:
Purpose: Games-based drills are the predominant form of training adopted during basketball practice. As such, researchers have begun to quantify the physical, physiological, and perceptual demands of different games-based drill formats. However, study methodology has not been systematically reported across studies, limiting the ability to form conclusions from existing research. The authors developed this call to action to draw attention to the current standard of methodological reporting in basketball games-based drill research and establish a systematic reporting standard the authors hope will be utilized in future research. The Basketball Games-Based Drill Methodical Reporting Checklist (BGBDMRC) was developed to encourage the systematic reporting of games-based drill methodology. The authors used the BGBDMRC to evaluate the current methodological reporting standard of studies included in their review published in the International Journal of Sports Physiology and Performance, “A Systematic Review of the External and Internal Workloads Experienced During Games-Based Drills in Basketball Players” (2020), which highlighted this issue. Of the 17 studies included in their review, only 38% (±18%) of applicable checklist items were addressed across included studies, which is problematic as checklist items are essential for study replication. Conclusions: The current standard of methodological reporting in basketball games-based drill research is insufficient to allow for replication of examined drills in future research or the application of research outcomes to practice. The authors implore researchers to adopt the BGBDMRC to improve the quality and reproducibility of games-based drill research and increase the translation of research findings to practice.

The development of portable ladder drills as a medium for agility training has never been touched once. The ladder drill tool's mobile concept will make it easier for the trainer to use the device with a variety of varied agility training movements and can be used in more sports. Based on this, the research was carried out in an effort to make portable ladder drill training media that is useful as a medium for agility training. This research uses research and development level 3 methods. Product trials are conducted in three types: one on one practices with four respondents, small group trials worked with five respondents athletes, students majoring in Sports Education FKIP Riau University, and large-scale tests. They worked on 11 athletes KONI and Dispora Riau Province. The data analysis technique used in this research is the quantitative descriptive analysis technique. Furthermore, data collection techniques using a questionnaire (questionnaire). The results of this study indicate that: assessments made by material experts, media experts, one-on-one trials, small-scale trials, and large-scale trials are above 83 percent. Based on this study's results, it can be concluded that the Development of Portable Ladder Drills is declared feasible as a medium to increase agility by sports actors. Considering that this development still has shortcomings, future research recommendations are related to providing cheaper and more functional product materials in terms of equipment installation efficiency.

Full textAbstract:
Evacuation capacity is very important in building fire. In order to improve the safety evacuation capacity of occupants, a web-based serious game for virtual fire evacuation drills is proposed. As a prototype of the serious game, a stand-alone system for virtual drill had been developed. On this basis, the system framework of the serious game is first designed for web-based training, including the database, front and back ends. Secondly, an optimization solution including fire scenes and web codes is designed for smooth rendering performance. Lastly, a solution is designed to visualize the evacuation paths of numerous trainees, which can be used to reveal the evacuation rules, and an evaluation model of evacuation performance is created considering the features of evacuation paths and fire hazards, to provide comprehensive feedback for trainees. Thus, a convenient and accessible web-based serious game was developed. More than 100 people participated in the online virtual evacuation drill of a dormitory building fire. Through the drills, the average evacuation time of the trainees decreases from 79.77 s to 54.32 s, and the safety scores of the trainees improve from 74.71 to 81.21. Therefore, the evacuation abilities of trainees gradually improve, which demonstrates the effectiveness of the drill. Consequently, virtual fire drills using a web-based serious game can play an important role in improving the evacuation ability.

Aerobic energy transference is highly required and accounts for more than 90% of total energy consumption during a soccer match. In addition high aerobic fitness contributes to recovery from high-intensity intermittent exercise, specific to performance in soccer. The aim of the present study was to examine whether the peak velocity in the Carminatti’s test (PVT-CAR) for prescribing interval-training drills is effective in eliciting aerobic-fitness development intensities in male soccer-players. Fifteen Brazilian male elite soccer-players (U20) were tested for T-CAR and monitored for heart rate (HR) during PVT-CAR prescribed interval-training drills (i.e., 4x4min with 3min passive recovery). Drills were performed with a 1:1 work-to-rest ratio with either straight-line (6/6s) or 180° shuttle running (12/12s). The interval training performed at PVT-CAR elicited HR above 90% of HRmax and lactate above 4m.mol.l-1. In the shuttle-running drills, HR and lactate (93.3±2.1% HRmax; 7.7±1.4 m.mol.l-1) were significantly higher than in the straight line drills (vs 90.3±2.6 %HRmax; 4.5±0.9 m.mol.l-1). The coefficient of variations showed low inter-subject variability in HR (CV 2.3 and 3.0% for 12/12 and 6/6 respectively). The results of this study demonstrated that PVT-CAR can be successfully used to individualize high-intensity interval running training in players with different aerobic profiles, while shuttle-running drills presented higher values at intern load than straight line. The physiological and time-motion profiles resemble the most demanding phases of the match, especially for the fittest players.

Purpose: To investigate the effects of ball drills and repeated-sprint-ability training during the regular season in basketball players. Methods: A total of 30 players were randomized into 3 groups: ball-drills training (BDT, n = 12, 4 × 4 min, 3 vs 3 with 3-min passive recovery), repeated-sprint-ability training (RSAT, n = 9, 3 × 6 × 20-m shuttle running with 20-s and 4-min recovery), and general basketball training (n = 9, basketball technical/tactical exercises), as control group. Players were tested before and after 8 wk of training using the following tests: , squat jump, countermovement jump, Yo-Yo Intermittent Recovery Test Level 1 (YIRT1), agility T test, line-drill test, 5-/10-/20-m sprints, and blood lactate concentration. A custom-developed survey was used to analyze players’ technical skills. Results: After training, significant improvements were seen in YIRT1 (BDT P = .014, effect size [ES] ± 90% CI = 0.8 ± 0.3; RSAT P = .022, ES ± 90% CI = 0.7 ± 0.3), the agility T test (BDT P = .018, ES ± 90% CI = 0.7 ± 0.5; RSAT P = .037, ES ± 90% CI = 0.7 ± 0.5), and the line-drill test (BDT P = .010, ES ± 90% CI = 0.3 ± 0.1; RSAT P < .0001, ES ± 90% CI = 0.4 ± 0.1). In the RSAT group, only 10-m sprint speeds (P = .039, ES ± 90% CI = 0.3 ± 0.2) and blood lactate concentration (P = .004, ES ± 90% CI = 0.8 ± 1.1) were improved. Finally, technical skills were increased in BDT regarding dribbling (P = .038, ES ± 90% CI = 0.8 ± 0.6), shooting (P = .036, ES ± 90% CI = 0.8 ± 0.8), passing (P = .034, ES ± 90% CI = 0.9 ± 0.3), rebounding (P = .023, ES ± 90% CI = 1.1 ± 0.3), defense (P = .042, ES ± 90% CI = 0.5 ± 0.5), and offense (P = .044, ES ± 90% CI = 0.4 ± 0.4) skills. Conclusions: BDT and RSAT are both effective in improving the physical performance of basketball players. BDT had also a positive impact on technical skills. Basketball strength and conditioning professionals should include BDT as a routine tool to improve technical skills and physical performance simultaneously throughout the regular training season.

Abstract This research aimed to define the key factors in freestyle flip turns via a kinesiology analysis to diagnose swimmers. Hence, specially designed drills were created to improve swimmers’ flip-turn skills and assess the effects of training. Nine Chinese national modern pentathlon athletes ranging in age from 20 to 26 years with an average of 10 years of training experience were tested and trained in this study. The Kistler Performance Analysis System for Swimming was used for the pre- and post-test analyses. A kinesiology analysis of the data from the pre-test was used for the diagnosis and specific drills were adopted for 10 weeks, 3 times per week before the post-test. The comparison of the pre- and post-test performances was used to assess the effects of training. After 10 weeks of specific drill training for flip turns, participants’ turning skills significantly improved. Speed in approaching, somersaulting, pushing-off and gliding all increased. The angles of the knees and hips as well as the force applied improved, which contributed to swimmers’ increased speed. Since the skills needed for a flip turn are complex and not easily diagnosed via observation alone, this kinesiology analysis will make diagnosis objective and easy.

IntroductionEmergency management education and large-scale disaster drills help to increase local capacity for dealing with a multitude of hazards. Video recordings of disaster drills offer participants with little exposure to fundamental emergency management principles an introduction to important topics and scenarios. Such resources allow ongoing training and education, thus maximizing the investment required to mount a large-scale exercise.MethodsDuring emergency management exercises in Mumbai, India between 2008 and 2010, video recordings of prior exercises were used to augment training for clinicians, administrators and public health practitioners. During the exercises, videos depicting scenario-based disaster drills were produced for use as teaching and evaluation tools focused on pre-hospital care, trauma life support, and hospital operations. Videos are distributed digitally and online, extending the teaching impact of multi-day courses and serving as a benchmark for future exercises.ResultsDuring the 2010 exercise in Mumbai, approximately eight hours of video footage were recorded by professional producers, and by participants in the evaluation and monitoring track of the course. That footage was added to a library from exercises in Ahmedabad and Mumbai, India, in 2007 and 2008. Video was used as a tool for immediate feedback on participant performance as well as the foundation for ongoing instruction. Videos allowed students to be sensitized to important issues prior to taking part in a drill, and to participate in the post-drill evaluation process.ConclusionVideo documents of disaster management exercises serve as a valuable addition to an ongoing program of emergency management education and preparedness. Short video pieces increase the effectiveness of a teaching program by providing re-usable, easily accessible, and setting-specific teaching tools.

Purpose:To examine the acute effects of generic drills (running drills [RDs]) and specific (small-sided-games [SSGs]) long-sprint-ability (LSA) drills on internal and external load of male soccer players. Methods:Fourteen academy-level soccer players (mean ± SD age 17.6 ± 0.61 y, height 1.81 ± 0.63 m, body mass 69.53 ± 4.65 kg) performed four 30-s LSA bouts for maintenance (work:rest 1:2) and production (1:5) with RDs and SSGs. Players’ external load was tracked with GPS technology (20-Hz), and heart rate (HR), blood lactate concentration (BLc), and rating of perceived exertion (RPE) were used to characterize players’ internal load. Individual peak BLc was assessed with a 30-s all-out test on a nonmotorized treadmill (NMT). Results:Compared with SSGs, the RDs had a greater effect on external load and BLc (large and small, respectively). During SSGs players covered more distance with high-intensity decelerations (moderate to small). Muscular RPE was higher (small to large) in RDs than in SSGs. The production mode exerted a moderate effect on BLc while the maintenance condition elicited higher cardiovascular effects (small to large). Conclusion:The results of this study showed the superiority of generic over specific drills in inducing LSA-related physiological responses. In this regard production RDs showed the higher postexercise BLc. Individual peak blood lactate responses were found after the NMT 30-s all-out test, suggesting this drill as a valid option to RDs. The practical physiological diversity among the generic and specific LSA drills here considered enable fitness trainers to modulate prescription of RD and SSG drills for LSA according to training schedule.

Abstract Soccer is a predominantly tactical sport and, therefore, tactical training has become the most widely used strategy to improve players' performance. The objective of the present study was to assess the workload of soccer-specific drills in professional players over a two-season period in an established context. GPS technology was used to record the data. One hundred and thirty-two (n = 132) soccer-specific drills were studied and grouped by categories. The individual demands of each task were related to the individual competitive profile of each player. The level of physical demand was significantly different in relation to the specific soccer drills analysed. Total distance covered, high-speed running, and the total number of high accelerations and decelerations were significantly higher in competition than in drills used for training sessions (p < .001). The Large-Sided Games (LSG), Big-Position Games (BPG) and Position Games (PG) showed higher maximum running speed values than the rest of the exercises (p < .01). The sum of high accelerations and decelerations values was greater in the Small-Sided Games (SSG) than in BPG (p < .001), Small-Position Games (SPG) (p < .001) and Physical-Technical Circuits (PTC) (p < .001). Significant differences were observed in the exercises analysed according to the player’s position. The current findings provide a detailed description of conditional demands placed on soccer players in different soccer-specific drills during training sessions, in a professional soccer context and according to their playing position, which may be helpful in the development of individualized training programs in other contexts.
