Neuromechanical strategies employed to increase jump height during the initiation of the squat jump

Journal of Electromyography and Kinesiology, 2004
The maximal height attained in a vertical jump is heavily influenced by the execution of a large countermovement prior to the upward motion. When a jump must be executed without a countermovement, as in a squat jump, the maximal jump height is reduced. During such conditions, the human body may use other strategies in order to increase performance. The

Influence of Squatting Depth on Jumping Performance

Journal of Strength and Conditioning Research, 2012
It is unclear if increases in 1 repetition maximum (1RM) in quarter squats result in higher gains compared with full depth squats in isometric force production and vertical jump performance. The aim of the research projects was to compare the effects of different squat variants on the development of 1RM and their transfer effects to Countermovement ...

On Squat Jump Exercise

Volume 3: Biomedical and Biotechnology Engineering, 2016
This paper deals with the mechanics of the human leg and forces in the muscles, ligaments, and joint contact in the leg during a squat jump exercise. An inverse dynamics approach is used in this work. A 2-D dynamic model of one limb in the sagittal plane is used to investigate this ballistic task.

Increasing Compliance to Instructions in the Squat Jump

Journal of Strength and Conditioning Research, 2008
The purposes of this investigation were to evaluate the occurrence of a small amplitude counter-movement (SACM) in SJ (squat jump) trials of elite athletes to determine the efficacy of gross observation and the use of a portable position transducer to determine whether or not a SACM occurred.

A biomechanical comparison of the vertical jump, power clean, and jump squat

Journal of Sports Sciences, 2014
The purpose of this study was to compare the kinetics, kinematics, and muscle activation patterns of the countermovement jump, the power clean, and the jump squat with the expectation of gaining a better understanding of the mechanism of transfer from the power clean to the vertical jump.

Acute Effects of Heavy-Load Squats on Consecutive Squat Jump Performance

Journal of Strength and Conditioning Research, 2008
Postactivation potentiation (PAP) and complex training have generated interest within the strength and conditioning community in recent years, but much of the research to date has produced confounding results. The purpose of this study was to observe the acute effects of a heavy-load back squat [85% 1 repetition maximum (1RM)] condition on consecutive ...

Kinetic Analysis of Concurrent Activation Potentiation during Back Squats and Jump Squats

Journal of Strength and Conditioning Research, 2010
Concurrent activation potentiation enhances muscular force during open kinetic chain isometric and isokinetic exercises via remote voluntary contractions (RVCs). The purpose of this study was to evaluate the effect of RVCs on the performance of closed kinetic chain ground-based exercises.

Power Output In The Jump Squat In Adolescent Male Athletes

Journal of Strength and Conditioning Research, 2010
The load that maximizes power output in the jump squat (JS) in collegeaged athletic males has been reported to be 0% of 1 repetition maximum [1RM] squat strength) or in other words body mass. No data exist concerning adolescent athletic males. In addition, strength levels have been theorized to possibly affect the load that maximizes power output in ...
