Abstract:
Weight predictions used to scale lifting forces adapt quickly when repeatedly lifting unusually weighted objects and are readily updated by explicit information provided about weight. In contrast, weight predictions used when making perceptual judgments about weight are more resistant to change and are largely unaffected by explicit information about weight. These observations suggest that distinct memory systems underlie weight prediction when lifting objects and judging their weights. Here we examined whether these weight predictions differ in their reliance on declarative and nondeclarative memory resources by comparing the adaptability of these predictions in older adults, who exhibit relatively impaired declarative memory processes, to those in younger adults. In the size condition, we measured lift forces as participants repeatedly lifted a pair of size-weight inverted objects in alternation. To assess weight judgments, we measured the size-weight illusion every 10 lifts. The material condition was similar, except that we used material-weight inverted objects and measured the material-weight illusion. The strengths of these illusions prior to lifting, and the attenuation of the illusions that arise when lifting inverted objects, were similar for both groups. The magnitude of the change in the illusions was positively correlated with implicit memory performance in both groups, suggesting that predictions used when judging weight rely on nondeclarative memory resources. Updating of lifting forces also did not differ between groups. However, within the older group the success with which lifting forces were updated was positively correlated with working memory performance, suggesting that weight predictions used when lifting rely on declarative memory resources.

Abstract:
This study investigates upper limb movement and electromyography (EMG) signals during snatch under various loading conditions and discusses results from six lifting phases. Qualisys motion analysis and Noraxon EMG systems were used to record upper limb movement and muscle activity. When lifting heavy weights, the maximum shoulder flexion angle exceeded 180° in the rise phase and thus, was higher than when lifting lower weight categories. The deltoid and biceps muscles exhibited higher activity during this phase when lifting heavy weights. It can be inferred that the deltoid muscle is activated in this phase in order to maintain the shoulder in an abducted position, and to maintain hyperflexion of the biceps. Muscle activity of the deltoid and biceps in the second pull phase also increased significantly during heavy weight lifting. We infer that the effective use of these two muscles in the second pull phase would produce higher peak barbell vertical velocity, increasing the amount of weight can be lifted. Muscle activity for the latissimus dorsi during first pull showed a statistically significant increase when lifting heavy weights. This ability by the latissimus dorsi to generate higher velocities early in the concentric phase (downswing) possibly contributed to the improved final performance during heavy weight lifting.

Abstract:
Introduction: Manual lifting operations continue to play a key role in the industrial and service sectors, inflicting physical strain on the musculoskeletal system, despite advances in automation. As a result, an experiment is carried out to assess the impact of two lifting task parameters; weight and height, based on the estimation of subjective responses and biomechanical loading, while lifting the weight symmetrically in the sagittal plane. Also to recommend the safe limit for manual lifting tasks. Methods: Twelve volunteer male students in the age group of 21 to 26 years performed lifting tasks from floor to 5 different heights (below the knee to ear level), with 5 different weights (10 to 20 kg) using free-style lifting techniques. The load pan with no handle was used for lifting weight, which is typically adopted in the Indian building construction field. The subjective estimate was obtained using workload assessment by body discomfort chart. The biomechanical loading (loading rate) for each lifted weight and height was collected using a force platform. Results: The results showed that heavier weights produced higher stresses than lower weights. The loading rate was found to be almost similar at waist or knee level. The loading rate was observed to be linearly increasing after waist level. The overall workload rating seems to be a good correlate with the mean loading rate to some extent. Conclusion: It is proposed to keep the maximum acceptable lifting weight from floor to knee, up to the ear level is 15 kg, to prevent any musculoskeletal or chronic injury.

Abstract:
Background Heavy weight lifting using a squat bar is a commonly used athletic training exercise. Previous in vivo motion studies have concentrated on lifting of everyday objects and not on the vastly increased loads that athletes subject themselves to when performing this exercise. Hypothesis Athletes significantly alter their lumbar spinal motion when performing squat lifting at heavy weights. Study Design Controlled laboratory study. Methods Forty-eight athletes (28 men, 20 women) performed 6 lifts at 40% maximum, 4 lifts at 60% maximum, and 2 lifts at 80% maximum. The Zebris 3D motion analysis system was used to measure lumbar spine motion. Exercise was performed as a “free” squat and repeated with a weight lifting support belt. Data obtained were analyzed using SAS. Results A significant decrease (P < .05) was seen in flexion in all groups studied when lifting at 40% maximum compared with lifting at 60% and 80% of maximum lift. Flexion from calibrated 0 point ranged from 24.7° (40% group) to 6.8° (80% group). A significant increase (P < .05) was seen in extension when lifting at 40% maximum was compared with lifting at 60% and 80% maximum lift. Extension from calibrated 0 point ranged from —1.5° (40% group) to —20.3° (80% group). No statistically significant difference was found between motion seen when exercise was performed as a free squat or when lifting using a support belt in any of the groups studied. Conclusion Weight lifting using a squat bar causes athletes to significantly hyperextend their lumbar spines at heavier weights. The use of a weight lifting support belt does not significantly alter spinal motion during lifting.

Abstract:
Background: Load knowledge has been identified as a factor affecting the risk of low back pain (LBP) during symmetric lifting. However, the effects of load knowledge in asymmetric lifting tasks have not been reported yet. The purpose of this study was to investigate the load knowledge influence on lifting biomechanics in asymmetric lifting tasks; Methods: Twenty-four male adults were recruited to complete a psychophysical lifting capacity test and a simulated asymmetric lifting task. The lifting task was set with load knowledge of ‘no knowledge’ (NK), ‘weight known’ (WK), ‘fragile material known’ (FK), and ‘weight and fragile material known’ (WFK) for different lifting load weights. Trunk kinematics and kinetics were collected and analyzed; Results: When fragility information was presented, trunk sagittal flexion acceleration, lateral flexion velocity and acceleration, and average lateral bending moment were significantly lowered at the deposit phase. Lifting a high load weight was found to significantly increase low back sagittal bending moment at the lifting phase and low back moments of all three dimensions at the deposit phase; Conclusions: The decrease of trunk kinematic load suggests that providing material fragility information to workers in asymmetric lifting tasks would be effective in reducing their risk of LBP.

Abstract:
10 undergraduate men were tested to determine the effects of lifting mode and frequency on psychophysically established maximum acceptable weight of lift for 4 hr. of work. The heart rate and rate of perceived exertion (RPE) of the individuals while lifting the maximum acceptable weight of lift were measured. When performing a 90° asymmetric lifting, subjects lifted approximately 10% less weight than lifted in symmetric lifting. Nonsignificant differences in maximum acceptable weight of lift, heart rate, and RPE values were found between asymmetric lifting with trunk rotation and asymmetric lifting with leg rotation. The lifting frequency significantly affected the maximum acceptable weight of lift, heart rate, and RPE. Heart rate and RPE increased with lifting frequency. The maximum acceptable weight of lift at 2 lifts/min. and 4 lifts/min. were approximately 91.5% and 82.5% of that of 1 lift/min., respectively.

Abstract:
Introduction: In India, physical manual activities in asymmetrical postures overtax the human musculoskeletal system, which may exceed workers' physical limitations. Thus the purpose of this study was to examine the physical stresses experienced by the subject, based on subjective and biomechanical loading estimates while lifting weights to various heights, in an asymmetric direction and propose the safe limit for manual lifting. Methods: A laboratory experiment was conducted utilizing twelve male subjects in the age group of 20 to 25 years who lifted 5 different weights between 10 to 20 kg from below the knee to various lifting heights (below the knee to ear level). The lifting task was performed in three asymmetric angles (45, 90, and 135-degree) using free-style lifting techniques. An ANOVA technique was used to analyze the influence of three parameters (Lifting weight, lifting height and asymmetric angle) on two responses; subjective estimates and biomechanical loading. The subjective estimate was obtained using workload assessment by body discomfort chart. The biomechanical loading (loading rate) was estimated from ground reaction force data, obtained from the force plate. Results: Both the responses; subjective estimates and biomechanical loading followed a consistent pattern in predicting physical stress. The result revealed that lifting weights with higher destination heights and asymmetry angles increased the physiological workload and discomfort. Experiments have shown that the loading rate is reduced by 8 to 10% for each increase in the 45-degree angle of asymmetry. Conclusion: In general, safe lifting of 15 kg weight up to ear level and 15 kg weight up to shoulder level are recommended for 45- and 90-degree asymmetry respectively to prevent any chronic injuries. A maximum of 12.5 kg lifting weight up to shoulder level is also proposed.

Abstract:
This paper deals with the design and control of a power assist system for lifting objects based on weight perception. We considered vertical lifting force (load force) as the desired dynamics for lifting objects with the power assist system. Load force consists of inertial force and gravitational force. We hypothesized that weight perception due to inertial force may differ from perceived weight due to gravitational force for lifting objects with a power assist system. Based on this hypothesis, we designed a 1-degree-of-freedom (DOF) (vertical up-down) power assist system and determined a psychophysical relationship between actual weights and power-assisted weights for lifted objects. We also determined the excess in the load forces that subjects applied when lifting objects with the system. The excessive load force causes problems such as sudden high acceleration of the lifted object, user safety and other concerns while lifting the object, loss of system maneuverability and stability, and possibly fatal accidents. We modified the power-assist control based on the psychophysical relationship and the load force characteristics. Modifying control reduced the excess in load forces and significantly enhanced maneuverability, naturalness, ease of use, stability, and safety. We proposed using the findings to design industrial power assist systems for transporting heavy objects in various industries such as assembly and manufacturing, mining, logistics and transport, construction, disaster management and rescue, and military operations.

Abstract:
This paper examines interrelationships between the cognitive concepts of load heaviness, perceived weight lifted, and the size-weight illusion effect, and their importance for setting load limits in manual lifting tasks. Results of three related studies are presented, including: (1) a questionnaire survey of the perceived relationship between physical weights and subjective perception of load heaviness for a large subject population; (2) modeling of the above relationship using the fuzzy linguistic approach; and (3) laboratory examination of the perceived weights and load heaviness for five pre-weighted boxes. Thirty subjects who participated in the questionnaire survey, were asked to provide estimates of the perceived weights and corresponding linguistic classification of load heaviness, while lifting five pre-weighted boxes. The subjects had previously gone through another phase of the project where they had determined their maximum acceptable weight of lifting using the psychophysical approach. The perceived weights were not significantly different from the physical weights for the 'light' to 'moderate' categories of load heaviness. Furthermore, the concept of recommended weight limit (RWL) fell in the 'light' load category for which the subjects were good judges of load heaviness. The results of this study provide support for setting the lifting limits based on the RWL concept designed to reduce the risk of low back injury.

Abstract:
In this study, the three-dimensional (3D) asymmetric maximum weight lifting is predicted using an inverse-dynamics-based optimization method considering dynamic joint torque limits. The dynamic joint torque limits are functions of joint angles and angular velocities, and imposed on the hip, knee, ankle, wrist, elbow, shoulder, and lumbar spine joints. The 3D model has 40 degrees of freedom (DOFs) including 34 physical revolute joints and 6 global joints. A multi-objective optimization (MOO) problem is solved by simultaneously maximizing box weight and minimizing the sum of joint torque squares. A total of 12 male subjects were recruited to conduct maximum weight box lifting using squat-lifting strategy. Finally, the predicted lifting motion, ground reaction forces, and maximum lifting weight are validated with the experimental data. The prediction results agree well with the experimental data and the model’s predictive capability is demonstrated. This is the first study that uses MOO to predict maximum lifting weight and 3D asymmetric lifting motion while considering dynamic joint torque limits. The proposed method has the potential to prevent individuals’ risk of injury for lifting.

Abstract:
This study investigated the effect of three different lifting instruction sets on the psychophysically selected loads. The instruction sets corresponded to three different load limit concepts: maximum acceptable weight of lift (MAWL), maximum comfortable weight of lift (MCWL), and maximum safe weight of lift (MSWL). Results demonstrated significant lifting instruction effects on the investigated dependent variables, including: selected load weight, selected load weight estimation, perceived physical effort, and perceived comfort and safety ratings associated with the selected load weights. Perceived acceptability of selected load weight was the only variable upon which lifting instructions did not have a significant effect. The results showed that the MAWL instruction led to selected loads that were significantly heavier than the loads selected under MSWL instructions. Also, the level of perceived physical effort under the MAWL condition was significantly higher than those obtained under the MSWL and MCWL conditions. Results from this study are consistent with previous research findings that psychophysical selection of lifting loads is very sensitive to the instructions provided to the subjects. It also is suggested that the application of the classical psychophysical approach to setting limits for manual materials handling tasks should be carefully reappraised.

Abstract:
Biceps brachii is one major elbow flexor, which is innervated by the musculocutaneous nerve from the C5 and C6 root. From 1987 to 1996, the elbow flexor restoration procedures were performed in 461 brachial plexus injured patients by means of 347 intercostal nerve transfers, with 105° arc of flexion and 2.05 kg weight lifting; intercostal nerve transfer to 34 gracilles and 7 rectus femoris free vascularized muscle transplantation, with 111.45 and 86° arc of flexion, and 2.77 and 1.9 kg weight lifting, respectively; 41 modified Steindler flexorplasty, with 74.9° arc of flexion and 2.01 kg weight lifting; 27 lattisimus dorsi muscle (Zancolli's bipolar method), with 127.7° arc of flexion and 3.15 kg weight lifting; 3 pectoralis major tendon (Goldner's method), with 85° arc of flexion and 1.3 kg weight lifting; and 2 triceps muscle (Carroll's method) with 85° arc of flexion and 1.5 kg weight lifting. A comparison shows that, the latissimus dorsi muscle transfer obtained the best result for arc of flexion and weight lifting, followed by the gracilles muscle and the intercostal nerve transfer procedure, respectively.

Abstract:
This study examined the effects of lifting technique, lifting frequency and lifting weight on oxygen uptake, pulmonary ventilation, heart rate, and rating of perceived exertion of the Chinese population. The physiological and psychological responses increased significantly with repetitive lifting workload. The workload was calculated from several lifting task characteristics including lifting frequency, lifting weight and lifting distance. The regressive formulas were produced statistically. The metabolic costs and psychological feeling could be reliably predicted from repetitive lifting workload and lifting technique. The workload limits of specific lifting tasks could be estimated by comparing predicted metabolic costs and psychological feelings with relevant available physiological and psychological tolerances of Chinese population. The study further revealed that lifting technique significantly affected lifting capacities.
