Abstract:

The majority of road cycling races finish with a sprint and as such sprints are a key determinant of success. Surprisingly, the scientific literature on this specific topic is scarce, with limited to few studies describing the characteristics of road cycling sprinters and the demands of road sprinting. Cyclists’ sprinting velocity, which is mostly influenced by power output and aerodynamic drag (CdA) is critical to performance outcomes. However, to date, there is very limited research specifically examining how to maximise road sprint velocity. Thus, the overall objective of the four studies o

Abstract:

Sprint cycling ability is a key determinant of road cycling performance, with many races designed specifically for sprinters. The ability to excel in the final sprint is relevant for both individual riders and teams. Despite the importance of sprints within professional road cycling, the characteristics of professional road sprints and sprinters have yet to be extensively described. Thus, the overall objective of the five research studies contained within this doctoral thesis was to describe road cycling sprint performance and improve the general understanding of the physical, technical and ta

Abstract:

Sprint performance is one of the major determining factors for success in many land-based sports. To improve sprint performance, coaches provide task-oriented verbal instructions to athletes, which could affect how the athlete focuses their attention while sprinting. Adopting an external focus of attention has been shown to enhance a number of motor skills, including sprinting, while an internal focus of attention has been shown to be detrimental to skill performance. However, there is a current gap in the literature regarding how track and field coaches provide internal and external focus ins

Abstract:

Sprint running is a complex, multi-joint movement that has been well studied in human research, largely through the analysis of 3-D kinematics and force-time signals obtained during non-fatigued running. In team sport, however, the unplanned nature of match play determines if and when sprint efforts occur, meaning that some efforts may be performed with minimal recovery and therefore likely in the presence of fatigue. While fatigue-induced changes in running technique have been shown to incite potentially injurious kinematic patterns, it is unclear whether these modifications occur because of

A traditional warm-up (WU) for track sprinters usually includes a general WU, a series of mobility drills and some short sprint strides lasting 30-60 min in total. A WU of this duration might cause significant fatigue and impair sprint performance.

Methods: Five highly trained males competitive in endurance sports performed three different WU protocols on separate days in their postseason period.

Abstract:

Sprinting is a fundamental activity in many team sports such as soccer, rugby, football, field hockey, and basketball. Specifically, the ability to rapidly increase sprint running velocity over short distances, which is often referrcd to as sprint acceleration ability, is of major importance to team-sport athletes since sprint efforts during team-sport matches are typically of short duration (e.g., 10-20 m, 2-3 s). Biomechanical characteristics of the acceleration phase of sprinting has previously been studied in track sprinters from a block start, but there is a dearth of research exploring t

Abstract The Effects of a Combined Supplementation of Creatine and Sodium Bicarbonate on Repeated Sprint Performance James Jeremy Barber There is well-established research that suggests both creatine and sodium bicarbonate are effective ergogenic aids. However, only one published study has examined the combined effects of creatine and sodium bicarbonate. The primary purpose of this study was to determine if a combined supplementation of creatine monohydrate and sodium bicarbonate would further enhance the well-documented effects of creatine supplementation alone on repeated sprint perform

Abstract:

Studies examining the physical demands of surfing, the physiological characteristics of surfers, training techniques and various indices important to surfing performance are limited and characterised by methodological discrepancies. This thesis consists of five studies to assess the competitive requirements, test specific repeat sprint fitness and the trainability of sprint paddling in surfers. Initially an understanding of surfing movement patterns and a determination of the reliability and validity of custom-made GPS units was established (SurfTraX, Gold Coast, Australia) (Study 1: The valid

Abstract:

Background: Post activation potentiation (PAP) is an increased muscular performance thatoccurs after maximal voluntary contraction. Previous studies have shown a significantincrease in explosive movements, such as sprint and jump performance, as an effect ofthese maximal contractions. Aim: The aim of this study was to analyze if PAP, in terms of heavy squats, has aperformance enhancing effect on 30 meter sprint, with a hypothesis that the maximal effortin the squat has a performance enhancing effect on 30 meter sprint. Method: Twelve healthy male Crossfit athletes from Crossfit Halmstad, age b

Abstract:

Various aspects of performance (e.g., sprint speed, grip strength) are thought to be important determinants of the success of animals in natural activities such as foraging, mating, and escaping from predators. However, it is generally known that morphological properties enhancing one type of performance (e.g., speed) can lead to a reduction in another (e.g., strength). Such performance trade-offs have been quantified at the inter-specific level, but evidence at the inter-individual level remains equivocal. To test for the presence of a performance trade-off, I initiated a study on wild white-

Abstract:

200-m sprint kayaking requires repeated cyclic force production, and athletes typically incorporate resistance training programs aimed at improving muscular strength and power and the ability to produce high forces over the course of the race (i.e. 31-40 s). Whilst upper body strength and whole-body maximal oxygen uptake have been associated with faster race times in sub-elite athletes, it is not known whether strength and aerobic capacity, or changes in them, influence performances in high-level kayak athletes. In Study 1 of the present thesis, relationships between isoinertial strength (i.e.

The purpose of this investigation was to determine the effects of a four day creatine load and simultaneous energy restriction on muscle creatine content, exercise performance, and body composition in 24 male recreational resistance trainers, age 18-26. Sixteen subjects were randomly divided into placebo (Pl, n=8) and creatine supplement (CrS, n=8) groups. Control (C, n=8) subjects of the same age were recruited separately g Ã d-1 to complete the performance and body composition tests while consuming their normal diet.

Abstract:

Muscle strength has been identified as an important contributor to athletic performance. Little attention however, has been paid to the specific relationship between peak isokinetic muscle strength and sprint starting performance. The aim of this study was to determine the influence of an adapted front knee angle, as determined by isokinetic assessment (the angle of peak torque production), on starting performance. Sixteen track sprinters, of elite-national or competitive-regional standard, were asked to perform eight sprints over 50m using four separate starting techniques. Technique 1 featur
