Fourteen healthy men participated in a study designed to examine the effects of weight-belt use on trunk-and leg-muscle myoelectric activity (EMG) and joint kinematics during the squat exercise. Each subject performed the parallel back squat exercise at a self-selected speed according to his own technique with 90% of his 1RM both without a weight belt (NWB) and with a weight belt (WB). Myoelectric activity of the right vastus lateralis, biceps femoris, adductor magnus, gluteus maximus, and…

Trunk Muscle Activity During Stability Ball and Free Weight Exercises
It appears that stability ball exercises may not provide a sufficient stimulus for increasing muscular strength or hypertrophy; consequently, the role of Stability ball exercises in strength and conditioning programs is questioned.
Muscle activation in the loaded free barbell squat: a brief review.
The purpose of this review was to examine studies that reported muscle activation measured by electromyography in the free barbell back squat with the goal of clarifying the understanding of how the exercise can be applied.
Reliability of a combined biomechanical and surface electromyographical analysis system during dynamic barbell squat exercise
The proven reliability of the three components of this system allows for real-time monitoring of resistance exercise using the preferred training methods of athletes, which could be valuable in the understanding of the neuromuscular response of elite strength training methods.
Back stress and assistance exercises in extreme weightlifting
It is demonstrated that the assistance exercises may all be suitable for conditioning the low back for the two Olympic lifts in elite weightlifters.
Effects of Whole-Body Electromyostimulation on Strength-, Sprint-, and Jump Performance in Moderately Trained Young Adults: A Mini-Meta-Analysis of Five Homogenous RCTs of Our Work Group
It is concluded that WB-EMS is a feasible complementary training stimulus for performance enhancement, however, additional effects on strength and power indices seem to be limited and sprint and jump-performance appear to be benefiting only slightly.
Effects of Unilateral and Bilateral Lower-Body Heavy Resistance Exercise on Muscle Activity and Testosterone Responses
The PS exercise may be an effective method for including unilateral exercise into lower-body resistance training when designing training programs for ground-based activities and similar lower limb and back sEMG and TES responses may indicate that the neuromuscular and hormonal demands were comparable for both the BS and PS exercises.
Influence of elastic lumbar support belts on trunk muscle function in patients with non-specific acute lumbar back pain
The present results suggest that the effect of elastic abdominal belts appears to be more of a temporary neutral alteration of trunk muscle coordination, with some trunk muscles becoming more active and others less, and not a case of uniform deconditioning as is suspected.
Gluteus Maximus and Hamstring Activation During Selected Weight-Bearing Resistance Exercises
Comparing the activation of the 2 muscle groups in all exercises, the GM seems to be the primary muscle recruited whereas the MSLS seems to produce greater gluteus maximus and HG activation.
The influence of weightlifting belts and wrist straps on deadlift kinematics, time to complete a deadlift and rating of perceived exertion in male recreational weightlifters
Abstract Both weightlifting belts and wrist straps are commonly used weightlifting training aids but their effects on deadlift kinematics and performance were still not known. This study examined the
Preliminary Analysis of StrongArm® Ergoskeleton on Knee and Hip Kinematics and User Comfort
This study was constructed to assess the influence of wearing semi-soft exoskeletons on hip and knee kinematics when engaging in a box lifting task. Six healthy college aged students (age: 21.7 ±


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.
The effect of an abdominal belt on trunk muscle activity and intra-abdominal pressure during squat lifts.
The muscle activity and IAP results of this study during short duration lifting tasks make it difficult to justify the prescription of abdominal belts to workers.
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.
