purpose the aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in triple iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. methods for the cross-sectional data analysis, the association between with overall race times and split times was investigated using simple...

background: the purpose of this study was to analyze the changes of t3, t4, tsh and cortisol in swimming and running college student athletes after one bout of competitive training session. materials and methods: for this purpose, 15 swimmers by the average age of 22.5±2.48 yrs, height of 177.17±2.31 cm, weight of 68.75±2.24, body mass index (bmi) 21.65±2.14 kg/m2 ) and 15 runner by the average...

Running movements are parametrised using a wide variety of devices. Misleading interpretations can be avoided if the interdependencies and redundancies between biomechanical parameters taken into account. In this synthetic review, commonly measured running discussed in relation to each other, culminating concise, yet comprehensive description full spectrum styles. Since goal is transport body c...

It is now well acknowledged that napping constitutes an inherent component of the human circadian system. To date, however, few studies have examined the effects of spontaneous napping on human free-running rhythms. This study investigated the free-running circadian periods of rest/activity and body core temperature in a group of young subjects who were permitted to nap during their time in iso...

body weight is influenced by both food intake and energy expenditure. acylated ghrelin enhances appetite, and its circulating level is suppressed by growth hormone. data on the acylated ghrelin responses to exercise of different intensities in obese individuals are currently not available. this study examined the effects of an intermittent exercise protocol on acylated ghrelin levels and hunger...

The human gluteus maximus is a distinctive muscle in terms of size, anatomy and function compared to apes and other non-human primates. Here we employ electromyographic and kinematic analyses of human subjects to test the hypothesis that the human gluteus maximus plays a more important role in running than walking. The results indicate that the gluteus maximus is mostly quiescent with low level...

In human and animal running spring-like leg behavior is found. In a spring-mass model, running proves to be self-stable in terms of external perturbations or variations in leg properties (e.g. landing angle). However, biological limbs are not made of springs but, rather, consist of segments where springlike behavior can be localized at joint level. Here, we use a two-segment leg model to invest...

The goal of the proposed bachelor thesis is to investigate algorithms to analyse how a human runs, based on the acceleration of their legs or feet measured with accelerometer chips. Different styles of running need to be detected reliably and distinguished from walking. It should be detected if a human runs uphill, downhill or on a flat path. In addition the stress to the body (e.g. on articula...
