BACKGROUND The purpose of this study was to compare strength, body composition, and functional outcome measures following performance of the back squat, leg press, or a combination of the two exercises. METHODS Subjects were pair-matched based on initial strength levels and then randomly assigned to 1 of 3 groups: a squat-only group (SQ) that solely performed squats for the lower body; a leg press-only group (LP) that solely performed leg presses for the lower body, or a combined squat and…

Influence of Feet Position and Execution Velocity on Muscle Activation and Kinematic Parameters During the Inclined Leg Press Exercise
TLDR
The inclined leg press exercise produces the highest muscle activation in the vastus medialis, regardless of the velocity, feet stance, or gender.
Effects of isokinetic eccentric versus traditional lower body resistance training on muscle function: examining a multiple-joint short-term training model.
Early adaptations in eccentric training show several advantages over those in concentric training. The purpose of this study was to quantify the effects of 4 weeks of multiple-joint eccentric versus
Effects of Isokinetic Eccentric versus Traditional Lower Body Multiple-Joint Resistance Training on Muscle Function in Recreationally Trained College-Aged Adults
TLDR
Eccentron multi-joint training displayed test specific improvements for lower body strength in a relatively short amount of time for a trained population.
A Comparison of Machine versus Free-Weight Squats for the Enhancement of Lower-Body Power, Speed, and Change-of-Direction Ability during an Initial Training Phase of Recreationally-Active Women
TLDR
Machine squat training may provide performance-enhancing benefits of equal or superior value to those obtained with free-weight squat training in recreationally active women during an initial training mesocycle, and stress the importance of task-specific training in this population of untrained women.
Evaluation of the Lower Limb Muscles’ Electromyographic Activity during the Leg Press Exercise and Its Variants: A Systematic Review
TLDR
The main findings indicate that the leg press exercise elicited the greatest sEMG activity from the quadriceps muscle complex, which was shown to be greater as the knee flexion angle increased.
Biomechanical Analysis to Determine the Most Effective Posture During Squats and Shallow Squats While Lifting Weights in Women
Purpose This study aimed to identify the most appropriate squat posture for women by analyzing different squatting methods and weights. Methods Twelve healthy women were recruited as subjects (age:
Using Machines or Free Weights for Resistance Training in Novice Males? A Randomized Parallel Trial
TLDR
Similar gains in muscularity, strength, and functional ability can be expected for male novices in RT regardless of the equipment being used and without a fallback when changing from machines to free weights.
Quadriceps muscle activity during commonly used strength training exercises shortly after total knee arthroplasty: implications for home-based exercise-selection
TLDR
Strength training exercises in more simple forms elicited higher voluntary peak quadriceps muscle activity than strengthTraining exercises in machines early after TKA, and simple home-based strength training exercises using e.g. elastic bands or the patients’ own bodyweight should be considered to alleviate muscle strength losses.

The Impact of Back Squat and Leg-Press Exercises on Maximal Strength and Speed-Strength Parameters
TLDR
The squat exercise increased the performance in SJ, CMJ, and reactive strength index more effectively compared with the leg-press in a short-term intervention, so if the strength training aims at improving jump performance, the squat should be preferred because of the better transfer effects.
Effect of range of motion in heavy load squatting on muscle and tendon adaptations
TLDR
The main finding was that DS training resulted in superior increases in front thigh muscle CSA compared to SS training, whereas no differences were observed in patellar tendon CSA.
Knee Joint Kinetics in Relation to Commonly Prescribed Squat Loads and Depths
TLDR
The results suggest that typical decreases in squat loads used with increasing depths are not enough to offset increases in pEKFM, and should be considered as a baseline for further research.
The effects of strength and power training on single-step balance recovery in older adults: a preliminary study
TLDR
It is suggested that resistance training may improve balance recovery performance, and that, in this small sample, PT did not lead to larger improvements in single-step balance recovery compared to ST.
3 Different types of strength training in older women.
TLDR
In conclusion, rapid strength training is more effective for the development of rapid force production of muscle than other specific types of strength training and by consequence, better develops the functional capabilities of older women.
A Comparison of Free Weight Squat to Smith Machine Squat Using Electromyography
TLDR
The free weight squat may be more beneficial than the Smith machine squat for individuals who are looking to strengthen plantar flexors, knee flexor spinae, and knee extensors.
Considerations for Normalizing Measures of the Star Excursion Balance Test
TLDR
When using the SEBT for experimental or clinical purposes, participants' excursion distances should be normalized to leg length to allow for a more accurate comparison of performance among participants.
A three-dimensional biomechanical analysis of the squat during varying stance widths.
TLDR
A 3-D biomechanical analysis of the squat is more accurate than a 2-D analysis, especially during the WS, and knee and hip moments were greater during theWS compared with the NS.
Biomechanics of the knee during closed kinetic chain and open kinetic chain exercises.
TLDR
This study quantified knee forces and muscle activity in CKCE and OKCE to help in choosing appropriate exercises for rehabilitation and training.
