Common methods to estimate vertical jump height (VJH) are based on the measurements of flight time (FT) or vertical reaction force. This study aimed to assess the measurement errors when estimating the VJH with flight time using photocell devices in comparison with the gold standard jump height measured by a force plate (FP). The second purpose was to determine the intrinsic reliability of the ...

The aim of the present study was to determine the effect of patellar taping (PT) on landing characteristics of the vertical ground reaction force (VGRF) and on flight time during a counter movement jump (CMJ). Eleven healthy male subjects (age: 31.1 ± 4.2 years) volunteered for the study. Each subject performed six CMJs under two different jumping conditions: with PT and without PT (WPT). The o...

In basketball high intensity jumping and sprinting performance is of importance. There seems to be a relationship between maximal strength (MSt) in general, but influence MSt the plantar flexors not investigated very well. Thus, aim this study was investigate on performance. 37 young elite players were included (age: 13.9±1.8 years; weight: 66.4±16.8 kg; height: 179.21±13.24 cm) countermovement...

background and objectives: it has been shown that a bout of jumping exercise with weighted vests increases the subsequent countermovement jump height. however, it is not clear whether the improvement in jump height is due to the enhancement of joint power or due to other mechanisms such as neural adaptations. methods: to investigate this dichotomy, we tested the acute neuromechanical changes fo...

Aim of the study: to identify mutual interaction between reaction a moving object with functional state central nervous system and kinematic-dynamic parameters complex coordination movement. Materials methods: 9 elite alpine skiers were participated in this study. Visual-motor variables assessed by computer for psychophysiological testing NS-Psychotest (Neurosoft, Russia). Dynamic movement duri...

Previous studies have associated angiotensin-converting enzyme (ACE) D allele with variability in the skeletal muscle baseline strength, though conclusions have been inconsistent across investigations. The purpose of this study was to examine the possible association between ACE genotype and skeletal muscle baseline strength in elite male and female athletes involved in different event expertis...

The purpose was to determine if cold whirlpool treatment decreases functional performance equally regardless of gender. A secondary aim was to determine if there is a gradual increase in functional performance across time. Twenty-one college-aged subjects volunteered to participate in this study and were required to perform four measures of functional performance including: counter movement ver...

The optic fiber method was utilised to measure in vivo Achilles (ATF) and patellar tendon forces (PTF) during submaximal squat jumps (SJ) and counter movement jumps (CMJ). Normal twolegged jumps on a force plate and one-legged jumps on a sledge apparatus were performed by four volunteers. Kinetics, kinematics, and muscular activity from seven muscles were recorded. The loading patterns of the t...
