The aim of this study was to investigate the effect of 6 wk of whole body vibration (WBV) training on sprint running kinematics and explosive strength performance. Twenty-four volunteers (12 women and 12 men) participated in the study and were randomised (n = 12) into the experimental and control groups. The WBV group performed a 6-wk program (16-30 min·d, 3 times a week) on a vibration platfor...

Objective: This investigation aimed to compare the effect of neuromuscular, strength and combined training on dynamic balance and sports performance including sprint, agility and power abilities in female basketball players. Method: In this semi-experimental study, 42 female professional basketball players (age 19-25 years) were assigned to three groups (neuromuscular (NM), strength (ST), and ...

Many studies have examined the effect of caudal autotomy on speed and behaviour of lizards escaping over horizontal surfaces, but there have been few studies on lizards escaping over vertical surfaces and, in particular, species that jump between surfaces. We examined jumping by the Cape dwarf gecko (Lygodactylus capensis) in terms of individuals’ varying states of tail autotomy and regeneratio...

Geostrophic turbulence near horizontal surfaces on which the vertical velocity vanishes exhibits a forward cascade of buoyancy variance, characterized by a shallow energy spectrum, secondary roll-up of filaments, and a fat-tailed vorticity probability distribution. Such surfaces occur at rigid boundaries, but also at discontinuous jumps in stratification. Here we relax this mathematical idealiz...

Force depression (FD) is a decrease in isometric force following active muscle shortening. Despite being well characterized experimentally, its underlying mechanism remains unknown. To develop a new, genetically manipulatable experimental model that would greatly improve our ability to study the underlying mechanism(s) of FD, we tested the Drosophila jump muscle for classical FD behavior. Stead...

introduction: the important of comparing performance of hospitals using hospital indicators, has been made the necessary of utilizing of the application model inevitable. this study aimed to compare hospital performance key indicators simultaneity. methods: in this descriptive cross sectional and retrospective study, 31 hospitals of isfahan university of medical sciences were evaluated in 2007....

objectives the purpose of this study was to determine the types of fall-related injuries and the related risk factors in the elderly population of qom province, iran. patients and methods this retrospective study was performed on 424 elderly people (65 years and over) referred to shahid beheshti hospital, qom, iran, due to falls between 2010 and 2012. the icd-10 codes of external causes of inju...

This work describes jump-to-contact STM-break junction experiments leading to novel statistical distribution of last-step length associated with conductance of a single atom contact. Last-step length histograms are observed with up to five for Fe and three for Cu peaks at integral multiples close to 0.075 nm, a subatomic distance. A model is proposed in terms of gliding from a fcc hollow-site t...

We consider one-dimensional discrete-time random walks (RWs) in the presence of finite size traps length $\ell$ over which RWs can jump. study survival probability such when are periodically distributed and separated by a distance $L$. obtain exact results for mean first-passage time special case double-sided exponential jump distribution. While typically survive longer than if they could not l...
