The purpose of this article is to compare the effects of quarter, parallel, and full depth squats on muscle activity, joint stress, athletic abilities, and potential injury risks for the consideration of all strength and conditioning professionals.

In this video from the NSCA's Personal Trainers Conference 2013, Brad Schoenfeld, MSc, CSCS, CSPS, FNSCA, discusses the benefits and mechanics of squats.

This article briefly explains different squat variations, as well as how they differ from a physics and biomechanics standpoint.

Traditional lower-body resistance exercise alone may not be an optimal means of developing agility. Further, the effectiveness of straight-sprint training on agility performance has not been well established. In contrast, jump training, including loaded jump squats and horizontal and lateral jumps, holds promise.

This article describes a five-week training program that was used to prepare an athlete for the NBA Combine.

Accentuated eccentric loading (AEL) can be combined with lower-body power-based movements to acutely enhance them; however, currently, there are limited recommendations for this training method. AEL can enhance force and power metrics during its utilization with lower-body power based exercises. When using AEL, exercises should consist of jump squats and countermovement jumps with loading methods consisting of weight releasors or dumbbell hand release. Elastic bands can be used; however, more research is needed in this area. External loads ranging from 10–30% of body mass can be used. Future research needs to investigate increased eccentric and concentric loads when using AEL with power based movements.

This article highlights the scientific evidence on exercises like the seated leg extension, leg curl, and adduction machines to highlight their potential benefits on enhanced performance and potentially reducing injury risk.

The squat is one of the most widely used exercises in resistance training programs. The aim of this narrative review was to analyze the effect of the squat on lower-limb muscle hypertrophy. Briefly, the available literature indicates that the squat is an effective exercise for inducing hypertrophy of the quadriceps, mainly the vastii, but also the rectus femoris, although to a reduced magnitude. Multiple lines of evidence suggest little to no hamstring hypertrophy from the back squat. Although the gluteus maximus clearly participates mechanically in the back squat, few longitudinal studies exist on the topic. The limited evidence available on this topic suggests deeper squats may be more hypertrophic for the gluteus maximus, and that, squat depth beyond 908 of knee flexion may not provide further hypertrophy of the knee extensors. Despite the popularity of the many squat variations, there are still controversies surrounding their hypertrophic potential for lower-limb musculature. Further studies are needed to investigate the hypertrophic effects of different squat variations, as well as differences in hypertrophy because of squat depth, stance, barbell position, and different squat apparatuses/machines.

This article provides essential guidelines for athletes beginning a strength and conditioning program that ensures safety and productivity of the training sessions.
