in order to determine the hygiene indices of bathing water, and it's water quality, a survey and laboratory analysis was recently undertaken on 34 outdoor public swimming pools out of a total 126 in tehran metropolitan area according to simple random sampling without replacement. this survey revealed remarkable evidence of waver bacterial contamination at heavy bather load time. examined water ...

Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study we observed the swimming behaviour of Atlantic salmon (Salmo salar L.) at a commercial farm with tidal currents altering between low, moderate and high velocities. At high current velocities the salmon switched from the traditional circular polarized g...

Background: There is an increasing popularity of waterpipe tobacco smoking (WTS) in youth and even inathletes worldwide. Despite the existence of evidence of the harmful effects of hookah smoke on varioussystems of the body, especially the cardiovascular system, its simultaneous effect with exercise training hasnot been well studi...

[Purpose] The purpose of the present study was to examine cognitive function in middle-aged and older adults regularly engaging in synchronized swimming-exercise. [Subjects and Methods] Twenty-three female synchronized swimmers ranging in age from 49 to 85 years were recruited for the present study. The duration of synchronized swimming experience ranged from 1 to 39 years. The control group co...

The influence of feeding hydrogenated fat (HF) or refined peanut oil (PO) diet and regular swimming exercise on hepatic and skeletal muscle antioxidant enzymes i.e., catalase ,and glutathione peroxidase (GPX) as well as tissue lipid peroxidation was investigated in male Wistar rats. Two groups of rats were fed diet with HF or PO as the only fat source. Both the groups were further divided into ...

background: many studies have been showed that certain illnesses including fungi and bacterial infections can be transmitted to human by contaminated swimming pools water. the main objective of the present study was to detect microbial (bacterial and fungi) and chemical (ph and chlorine levels) pollutions of the all swimming pools water in hamadan city, iran . methods: this study was a cross-se...

Ireland has one of the highest prevalence rates of asthma in the world with 1 in 7 children and 1 in 10 adults affected. 1 Its symptoms are characterised by either cough, feeling of chest tightness or wheezing which can be episodic or triggered by colds, sudden change in temperature, exercise or exposure to environmental allergens. Although some exercises can exacerbate its symptoms, swimming i...

Box jellyfish carry an elaborate visual system consisting of 24 eyes, which they use for driving a number of behaviours. However, it is not known how visual input controls the swimming behaviour. In this study we exposed the Caribbean box jellyfish Tripedalia cystophora to simple visual stimuli and recorded changes in their swimming behaviour. Animals were tethered in a small experimental chamb...

The aim of the study was to develop a method for measurement and analysis of kinematics of the pelvic girdle movement in breaststroke swimming to support training of technical skills. The measurements were performed in five elite breaststroke swimmers. A recording device for triaxial accelerations and triaxial rotational angular velocity was mounted on the dorsal part of the pelvic girdle of th...
