This study investigated the changes in performance and sex difference in performance of the world best triathletes at the ITU (International Triathlon Union) World Triathlon Series (i.e. 1.5 km swimming, 40 km cycling and 10 km running) during the 2009-2012 period including the 2012 London Olympic Games. Changes in overall race times, split times and sex difference in performance of the top ten...

Asthmatics often find that reasonably hard exercise of moderate duration like 6-8 minutes of continuous moderately hard running causes troublesome exercise induced asthma (EIA) while either very brief, intense exercise or very prolonged exercise does not necessarily cause an attack (Fitch et al, 1976). Neither the cause of EIA nor the reasons why some forms of exercise have greater propensity t...

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 simp...

A reduction in transfer factor of the lung for carbon monoxide (Tl(co)) is a consistent finding after saturation dives and is reported after some open sea air dives. Several diving associated factors may contribute to this reduction in Tl(co) including hyperoxia, venous gas microembolism, increased breathing resistance and immersion. Exercise, which inevitably is associated with open sea diving...

the aim of the present research was to study the effects of regular training and exhaustive exercise on t-pa/pai-1 complex in the blood of forty eight rats. they were divided randomly into control and experimental groups and the subgroups included the primary acute, secondary acute and 8-wk regularly trained (each group 8 rats). endurance training programs (five days a week, speed 15-22 m/min f...

Introduction: Physical activity and obesity affect the release of effective adipokines. In this regard, the present study investigated the effects of intermittent and continuous exercise in water and land (running on a treadmill) on visfatin, insulin, and blood glucose in pre and post menopausal obese women. Methods: In this quasi-experimental study, 18 obese women of Bandar Abbas City were ...

Purpose: Obesity is one of the most common problems in the world. Imbalance between energy consumption and expenditure is a main factor in weight disorder. Exercise helps losing weight by increasing energy expenditure and modulation of the energy intake. The present study examined protective effects of daily moderate aerobic exercise on preventing weight gain in high fat diet rats. Materia...

Background: Strenuous exercise and temperature outside the optimum are associated with hypothalamic dysfunction and therefore disruption of fertility in females. The aim of this study was to evaluate serum Estradiol level and follicogenesis in adult mice exposed to forced swimming in different temperature waters. Materials and Methods: Adult female mice were randomly divided into four groups as...
