Swimming is a healthy exercise that is well tolerated by asthmatics because it induces less severe bronchoconstriction than other forms of physical activity. This protective effect of swimming probably results from the high humidity of inspired air at water level, which reduces respiratory water loss and possibly osmolarity of airways mucus. The horizontal position of the body during swimming m...

abstract background and objective: diabetes mellitus is associated with cardiomyopathic changes, can be mediated by an oxidative stress. we aimed to study the effects of regular aerobic training and arbutin supplementation on total oxidant status (tos) and total antioxidant (tas) status in the cardiac tissue of diabetic rats. material and methods: fourty-two male wistar rats with an average wei...

The purpose of this article is to provide a critical commentary of the physiological and psychological tools used in the evaluation of swimmers. The first-level evaluation should be the competitive performance itself, since it is at this juncture that all elements interplay and provide the 'highest form' of assessment. Competition video analysis of major swimming events has progressed to the po...

OBJECTIVE To investigate the possible effects of regular swimming exercise on bone mineral density (BMD) compared with free activity after cast immobilization of rats. METHODS We carried out the study from April 2005 to June 2005 at the Department of Sports Medicine, Medical School of Suleyman Demirel University, Isparta, Turkey. The study included a total of 24 female Wistar rats. The rats w...

The purpose of the present study was to investigate the effects of feedback on the freestyle swimming learning and performance of novice swimmers. Sixty male (Mage=18.7, SD=1.82) first year students were randomly assigned into four groups: self-modeling, expert-modeling, verbal, and control group. The intervention program lasted for seven weeks. Participants were evaluated in 25m freestyle swim...

objective(s): this study evaluated the effect of swimming exercise during spontaneous methamphetamine (meth) withdrawal on the anxiety, depression, obsessive-compulsive disorder (ocd) and voluntary meth consumption in meth-dependent rats.  materials and methods: male wistar rats were repeatedly administered with bi-daily doses of meth (2 mg/kg, subcutaneous) over a period of 14 days. exercised ...

The incubation period is 2 -10 days, and the chief symptom is water...

To evaluate the combined effects of cardiac overload imposed by hypertension and by chronic exercise, male and female rats were made hypertensive by unilateral renal artery stenoses and made to exercise in an 8-10-wk swimming program. Sedentary normotensive animals, sedentary hypertensive animals and normotensive animals exposed to the swimming program were also studied. Hypertension was associ...

The aim of the present study is to test the hypothesis that sprint swimming performance is enhanced by in-water passive recovery (IN) after sprint swimming bouts in well-trained adolescent swimmers. Using a randomized crossover study design, twelve well-trained adolescent swimmers performed two tests at the swimming pool after preliminary testing. They performed 5 bouts of 100m all-out swimming...

Respiratory muscle training (RMT) has been shown to improve divers swimming endurance at 4 feet of depth; however, its effectiveness at greater depths, where gas density and the work of breathing are substantially elevated has not been studied. The purpose of this study was to examine the effects of resistance respiratory muscle training (RRMT) on respiratory function and swimming endurance at ...
