Sports Exerc., Vol. 34, No. 4. pp. 682-688, 2002. Purpose: Strength athletes often employ the deadlift in their training or rehabilitatioin regimens. The purpose of this study was to compare muscle activity between] sumo and conventional stvle deadlifts. and between belt and no-belt conditions. Methods: Six cameras collected 60… 


A three-dimensional biomechanical analysis of sumo and conventional style deadlifts.
Bomechanical differences between sumo and conventional deadlifts result from technique variations between these exercises, and understanding these differences will aid the strength coach or rehabilitation specialist in determining which deadlift style an athlete or patient should employ.
Biomechanical analysis of the deadlift during the 1999 Special Olympics World Games.
The sumo deadlift may be more effective in working ankle dorsiflexors and knee extensors, whereas the conventional dead Lift may beMore effective in worked ankle plantar flexor and knee flexors.
An Electromyographical Comparison of the Squat and Knee Extension Exercises
The parallel squat elicited more electrical activity than the knee extension in both muscles, and the downward shift in frequency of the EMG signal was greater for both the VM and VL during the parallel squat.
The effectiveness of weight-belts during multiple repetitions of the squat exercise.
Analysis of weight-belts during multiple repetitions of the parallel back squat exercise suggests that a weight-belt aids in supporting the trunk by increasing IAP, and that any differential effect due to wearing aWeight-belt did not occur over eight repetitions.
The effectiveness of weight-belts during the squat exercise.
Data suggest that a weight-belt can aid in supporting the trunk by increasing IAP, and integrated EMG activity of the muscles and adjusted mean values for back compressive force and back muscle force followed a similar but opposite pattern.
Stance width and bar load effects on leg muscle activity during the parallel squat.
The results suggest that stance width does not cause isolation within the quadriceps but does influence muscle activity on the medial thigh and buttocks.
High- and low-bar squatting techniques during weight-training.
The weightlifters had the load more equally distributed between hip and knee, whereas the powerlifters put relatively more load on the hip joint, and the thigh muscular activity was slightly higher for the powerlifting.
Lumbar spine loads during the lifting of extremely heavy weights.
There is large variability in the pattern of loading joints among national class powerlifters, and formulation of linear regression equations to predict the load lifted using reaction joint moments yielded substantial unexplained variability, though significant relationships were found.
Biomechanics of the squat exercise using a modified center of mass bar.
It was estimated that the greater IAP was responsible for relieving back muscle forces and compression by up to 15 and 21%, respectively, and increased stress with the weight at shoulder height stimulated a response for greater I AP to help alleviate the stresses on the spine.
Electromyographic analysis of the squat performed in self-selected lower extremity neutral rotation and 30 degrees of lower extremity turn-out from the self-selected neutral position.
A four-way analysis of variance indicated that the main effect of lower extremity position and the interaction of extremities position and knee joint angles were not found to cause significant changes in muscle activity patterns.
