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.

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 ...

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 ...

Altered Squat Jumping Mechanics After Specific Exercise

International Journal of Sports Medicine, 2010
This study examined squat jumping (SJ) mechanics following length restricted strength training regimens of the knee extensors and flexors. SJ from a 110 degrees knee joint angle starting position and isometric moment-knee angle relations of knee extensors and flexors were analysed in 16 athletes before and directly after 8 weeks of strength training ...

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.

Does bilateral index differ between countermovement jump, drop jump and squat jump?

Computer Methods in Biomechanics and Biomedical Engineering, 2012
In the literature, it has already been reported that in a two-legged vertical jump humans achieve less than twice the jump height they are able to reach in a one-legged jump (van Soest et al.

Could the Deep Squat Jump Predict Weightlifting Performance?

Journal of Strength and Conditioning Research, 2009
This research was carried out with the aim of describing the deep squat jump (DSJ) and comparing it with the squat (SJ) and countermovement (CMJ) jumps, to introduce it as a strength testing tool in the monitoring and control of training in strength and power sports. Forty-eight male subjects (21 weightlifters, 12 triathletes, and 15 physical education

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.
