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 ...

Relationship Between Relative Net Vertical Impulse and Jump Height in Jump Squats Performed to Various Squat Depths and With Various Loads

International Journal of Sports Physiology and Performance, 2010
Purpose:The purpose of the current investigation was to determine the relationship between relative net vertical impulse (net vertical impulse (VI)) and jump height in the jump squat (JS) going to different squat depths and utilizing various loads.Methods:Ten males with two years of jumping experience participated in this investigation (Age: 21.8 ± 1.9

Biomechanical Analysis of Squat Jump and Countermovement Jump From Varying Starting Positions

Journal of Strength and Conditioning Research, 2013
The purpose of this study was to investigate the effect of 2 strategies, defined by foot placement during the initiation of the take-off on performance in vertical jumps. The additional area of interest in this experiment was whether technique of the take-off phase might be an exploratory factor that has different electromyogram (EMG) muscle activity ...

Two-Leg Squat Jumps in Water: An Effective Alternative to Dry Land Jumps

International Journal of Sports Medicine, 2009
The current study was designed to quantify and compare the kinetic parameters of two-leg squat jumps carried out on dry land, in water and in water using area devices that increase drag force. Twelve junior female handball players who had been competing at national level for the previous two years volunteered to participate in the study.

Reliability and Factorial Validity of Squat and Countermovement Jump Tests

The Journal of Strength and Conditioning Research, 2004
The primary aim of this study was to determine reliability and factorial validity of squat (SJ) and countermovement jump (CMJ) tests. The secondary aim was to compare 3 popular methods for the estimation of vertical jumping height. Physical education students (n = 93) performed 7 explosive power tests: 5 different vertical jumps (Sargent jump, Abalakow'

The influence of squat depth on maximal vertical jump performance

Journal of Sports Sciences, 2007
An increase in the period over which a muscle generates force can lead to the generation of greater force and, therefore, for example in jumping, to greater jump height. The aim of this study was to examine the effect of squat depth on maximum vertical jump performance.
