Resting blood volumes and arterial and central venous pressures (CVP) were measured in 14 men before and after exercise training to determine whether training-induced hypervolemia is accompanied by a change in total vascular capacitance. In addition, resting levels of plasma arginine vasopressin (AVP), atrial natriuretic peptide (ANP), aldosterone (Ald), and norepinephrine (NE) were measured. T...

The aim of the study was to assess changes in endurance performance in young runners (females and males) during two training seasons. It involved 19 male and 16 female athletes aged 15-17 specializing in track-and-field middle and long distances runs. The following parameters were measured three times during the training season: maximal oxygen uptake, running economy, and the level of the secon...

Background. In team sports, according to perform variety of motor skills, development of special bio-motor abilities and imposed proper exercise stress, hematologic adaptations following exercise will be different. Objectives. Therefore, the aim of this study was the effects of six weeks combined training program on hematological parameters in elite basketball players. Methods. Fifteen athl...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : supervised exercise-based cardiac rehabilitation programs (crp) have been suggested to all patients, especially after myocardial infarction. however, the effects of cardiac rehabilitation on systolic function are controversial. the aim of this study was to examine the effects of an 8-week cardiac rehabilitatio...

BACKGROUND A sport-specific conditioning program can help tennis players train for competition or return to play from injury. This study determined the actual tennis serve volume in elite play and used these data to construct an interval training program based on stroke volume. HYPOTHESIS There will be no differences in serve volume between male and female tennis players at the professional a...

The aim of the present study was to investigate the difference in the horizontal mechanical determinants of sprint performance in highly-trained elite field hockey players versus subelite field hockey players. Thirty-five highly trained field hockey players (18 elite international players and 17 sub-elite players) were tested during the competitive season. They performed a maximal 40 meter spri...

Intensive exercise like strength training increases blood lactate concentration [La]. [La] is commonly used to define the metabolic stress of an exercise and depends on the lactate production, transportation, metabolism, and elimination. This investigation compared multiple set training of different volumes to show the influence of exercise volume on [La]. Ten male subjects performed 3 sets of ...

The purpose of this study was to examine the effects of omega-3 supplementation on young wrestler's pulmonary function during intensive wrestling training. Forty healthy young male wrestlers participated in this study. The subjects were randomly divided into experimental (n=10), placebo (n=10), active control (n=10) and inactive control (n=10) groups. Participants in experimental, placebo and a...

Moderate- to high-intensity strength training is recommended for healthy adults. In young subjects, a single session of strength training decreases blood pressure, while heart rate and cardiac work remain elevated afterwards. However, these effects have not been clearly demonstrated in elderly subjects. To investigate this issue, 16 elderly subjects each underwent a Control and an Exercise (3 s...
