The aim of this study was to determine the precise effect of plyometric training (PT) on vertical jump height in healthy individuals. Meta-analyses of randomised and non-randomised controlled trials that evaluated the effect of PT on four typical vertical jump height tests were carried out: squat jump (SJ); countermovement jump (CMJ); countermovement jump with the arm swing (CMJA); and drop jum...

the purpose of this study was to determine the intensity influence of perform one set half squat on vertical jump performance and muscle electrical activity in adolescent athletes. the subjects were 12 adolescent boys athletes. the subjects performed one set of dynamic half-squat using low and high intensities (li= low intensity with 40% 1rm, hi= high intensity with 80% 1rm), and a control (c) ...

BACKGROUND Vertical jump is an index representing leg/kick power. The explosive movement of the kick is the key to scoring in martial arts competitions. It is important to determine factors that influence the vertical jump to help athletes improve their leg power. The objective of the present study is to identify anthropometric factors that influence vertical jump height for male and female mar...

psychological and educational findings show that preschool years play a very important role in educating and developing children. one of the dimensions of development is motor development. the survey of motor performance with respect to anthropometric characteristic is of utmost importance. thus, the aim of this study was to survey the relationship between dimensional anthropometric characteris...

purpose the purpose of this study was to describe the body structure and morphological characteristics of tunisian elite handball players, and to determine the effect of these variables on functional and physical performance levels. methods a sample of 42 male handball players (mean age 21.98±3.24 years; training duration 12 years) at international level was submitted to a test battery comprisi...

Introduction A vertical jump is a movement that is used in a plethora of sports. The primary goal of a vertical jump is normally to reach the greatest possible height. Other goals could include hitting an object such as a football or a tennis ball, intercepting the path of an object such as a basketball or volleyball etc. Because of the frequent use and the importance of the vertical jump in ma...

This study examined whether an extrinsic motivator, such as an overhead goal, during a plyometric jump may alter movement biomechanics. Our purpose was to examine the effects of an overhead goal on vertical jump height and lower-extremity biomechanics during a drop vertical jump and to compare the effects on female (N = 18) versus male (N = 17) athletes. Drop vertical jump was performed both wi...

This study evaluated force and velocity parameters of vertical jump performance in countermovement jump (CMJ) and squat jump (SJ) and compared results for sprint runners and volleyball players. Twenty-four male athletes (12 regional/national-level sprint runners and 12 national-level volleyball players) performed CMJ and SJ on a force platform. The following variables were analyzed: jump perfor...

Vertical jump performance tests can give considerably different results, even when different methods are used to analyze the same jump trial from the same subject. To evaluate and compare 4 different methods commonly used to measure vertical jump performance, 52 physically active men each performed 5 maximal vertical jumps. Kinetic and kinematic data were used to analyze each trial using the 4 ...
