We determined the effect of long-term aerobic swimming training regimens of different intensities on colonic carcinogenesis in rats. Male Wistar rats (11 weeks old) were given 4 subcutaneous injections (40 mg/kg body weight each) of 1,2-dimethyl-hydrazine (DMH, dissolved in 0.9% NaCl containing 1.5% EDTA, pH 6.5), at 3-day intervals and divided into three exercise groups that swam with 0% body ...

Objective This study investigated the possible blood changes in wistar rats elderly with and without treatment with anabolic steroids submitted physical training. Materials and methods Elderly rats (32) were divided into four groups: normal (N), treated normal (NT), diabetic (D) and treated diabetic (DT). They were submitted to 20 sessions of swimming with overload (5% body weight), 40 min/da...

PURPOSE To evaluate the reliability and sensitivity to training of an audio-paced incremental swimming test. METHODS Eight young national-level male swimmers (age 15 +/- 1 year) performed a 7 x 200-m incremental swimming test (velocities 1.19, 1.24, 1.28, 1.33, 1.39, and 1.45 m/s and maximal sprint pace) using an audio-pacing device. The same test was performed 4 times by each participant, 1 ...

Introduction: Holding the breath during exercise causes hypoxia. This study set out to investigate the effect of the 12-week hypoxic interval training on lung volume and records of elite swimmers in 50 and 100 meters breaststroke. Methods: In this quasi-experimental study, 22 male swimmers were randomly divided into the hypoxic interval training group (n: 13; age: 16.61±1.39 years; he...

In the world of sports, modern information technologies are increasingly used to improve results and training athletes. Swimming is no exception, new revolutionizing this sport [1].

With the finding that short, intense sprints can improve aerobic capacity (Tabata, et al., 1996), there has been a huge increase in the number of experts who advocate this kind of training over traditional endurance training. Several successful swim coaches are among those recommending more high-intensity training while an equal or even greater number are warning of the pitfalls of training in ...
