Abstract Blatnik, JA, Skinner, JW, and McBride, JM. Effect of supportive equipment on force, velocity, and power in the squat. J Strength Cond Res 26(12): 3204–3208, 2012—The purpose of this investigation was to examine various kinetic and kinematic variables associated with squats without and with the use of a squat suit (SS). No previous investigation has examined the effect of an SS on squat performance. Participants were 8 elite or professional level male powerlifters (height = 178.59 ± 3.5…

Force Outputs during Squats Performed Using a Rotational Inertia Device under Stable versus Unstable Conditions with Different Loads

Findings support the use of the rotational inertia device to train the squatting exercise under unstable conditions for strength and conditioning trainers and could also be included in injury prevention programs for muscle lesions and ankle and knee joint injuries.

The Efficacy of Wrestling-Style Compression Suits to Improve Maximum Isometric Force and Movement Velocity in Well-Trained Male Rugby Athletes

There was no substantial effect of wearing a CG suit on CMJ and sprint performance, but the improvement in peak force generation capability in an IMTP may be of benefit to rugby athletes involved in scrummaging or lineout lifting.

Effect of a Neoprene Knee Sleeve on Performance and Muscle Activity in Men and Women During High-Intensity, High-Volume Resistance Training

It is suggested that wearing compressive neoprene KSs has no effect on improving performance and associated variables during high-load, high-volume lower-body resistance training.


This study compared back squat biomechanics in elite powerlifters under various equipment and intensity manipulations. Eleven elite powerlifters performed back squats in the following conditions:

The Year in Strength Science 2012

The authors found that lifters attained a greater 1RM with the hex bar, and both hex and straight bar deadlifts generated peak powers in the neighborhood of 4500 W in this study, comparable to power outputs reported for the clean.

A Review of the Biomechanical Differences Between the High-Bar and Low-Bar Back-Squat.

A review of the biomechanical differences between the high-bar and low-bar back-squat showed that the HBBS is characterized by greater knee flexion, lesser hipflexion, a more upright torso, and a deeper squat.

Journal of Exercise Physiologyonline Editor-in-Chief JEPonline Effect of 16 Weeks of Periodized Resistance Training on Strength Gains of Powerlifting Athletes

The results of this study indicate that linear periodization training applied in powerlifting athletes is an efficient method to increase muscular strength.

POWERLIFTING: Understanding the modality

The aim of this study was to understand powerliftin g sport associated with morphofunctional aspects involving modality. For th is, were a literature review search articles dealin g with the

A Review of the Efficacy of Weight Training Aids

The use and EFFECTIVENess of many weight training programmes for AIDS are discussed, offering practitioners the ability to make an informed decision on their use.

Analysis of USA Powerlifting Federation Data From January 1, 2012–June 11, 2016

This article reports 47,913 officially judged contestant results from powerlifting matches from January 1, 2012 to June 11, 2016 for the USA Powerlifting Federation and finds age and sex to be the most complex factors in predicting powerlifting results.



Comparison of Kinetic Variables and Muscle Activity During a Squat vs. a Box Squat

Removing the stretch-shortening cycle during the squat (using a box) appears to have limited negative consequences on performance, and minimal differences were observed in kinetic variables and muscle activity between the squat and box squat.

Validation of power measurement techniques in dynamic lower body resistance exercises.

Investigation of power measurement techniques utilizing various kinematic and kinetic devices during the jump squat, squat (S) and power clean (PC) indicates that data collection and analysis procedures influence the power output calculated as well as the load-power relationship of dynamic lower body movements.

Effects of load on ground reaction force and lower limb kinematics during concentric squats

The results suggest that maximal force exertion during squat exercises is not achieved at the same position of the lower body as external load is increased, in contrast, joint velocity coordination does not change as load is increasing.

Relationship Between Maximal Squat Strength and Five, Ten, and Forty Yard Sprint Times

This investigation provides additional evidence of the possible importance of maximal squat strength relative to BM concerning sprinting capabilities in competitive athletes.

A Biomechanical Analysis of the Squat Between Competitive Collegiate, Competitive High School, and Novice Powerlifters

Coaches should focus their training programs on increasing strength in unskilled powerlifters for the purpose of increasing acceleration from the bottom of the lift.

Effects of the Bench Shirt on Sagittal Bar Path

It is suggested that the bar path in bench shirt trials is more efficient and consistent than in the no-shirt trials, and this pattern demonstrates that a bench shirt can improve load capacity.

Effect of Knee Position on Hip and Knee Torques During the Barbell Squat

Although restricting forward movement of the knees may minimize stress on the knees, it is likely that forces are inappropriately transferred to the hips and low-back region and appropriate joint loading during this exercise may require the knees to move slightly past the toes.

Evaluation of a lower-body compression garment

The elasticity of the compressive garment provides increased flexion and extension torque at the end range of extension and flexion, respectively, and may assist the hamstrings in controlling the leg at theend of the swing phase in sprinting.

The purpose of this article is to examine kinematics and kinetics of the dynamic squat with respect to the ankle, knee, hip and spinal joints and to provide recommendations based on these biomechanical factors for optimizing exercise performance.

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.
