This study aimed to examine the acute effect of different durations static stretching on heart rate variability (HRV) and, anaerobic capacity moderately physically active men during Wingate test (WAnT) at two pre-exercise periods. Sixty-five healthy young male volunteers performed 10 s (STS) and 30 (LTS) consisting five exercises before WAnT non-consecutive days. HRV was measured pre (60 s), (3...

AIM The mechanism linking exercise intensity to the magnitude of the immune response is not completely understood. The purpose of this investigation was to determine whether the immune response to resistance exercise was associated with (1) changes in workload or (2) anaerobic exercise intensity. METHODS Previously untrained women underwent 6 months of resistance training for lower and upper ...

Background. Exertional fatigue, which frequently limits exercise in patients with chronic heart failure, is associated with early anaerobic metabolism in skeletal muscle. The present study was designed to examine the skeletal muscle metabolic response to exercise in this disorder and determine the relation of reduced muscle blood flow and skeletal muscle biochemistry and histology to the early ...

Uncontrolled studies have suggested that the newer oral phosphodiesterase inhibitors milrinone and enoximone acutely improve exercise performance in patients with severe chronic cardiac failure. To determine whether an oral placebo presented as an inotropic agent could acutely enhance exercise capacity, two separate groups of stable heart failure patients were studied by serial exercise testing...

BACKGROUND Children's physical activity patterns are characterized by short-term anaerobic activities. Anaerobic exercise performance in children with cystic fibrosis (CF) has received little attention compared to aerobic performance. This study investigated the effects of anaerobic training in children with CF. DESIGN AND METHODS Twenty patients were randomly assigned to the training group (...

There are 3 distinct yet closely integrated processes that operate together to satisfy the energy requirements of muscle. The anaerobic energy system is divided into alactic and lactic components, referring to the processes involved in the splitting of the stored phosphagens, ATP and phosphocreatine (PCr), and the nonaerobic breakdown of carbohydrate to lactic acid through glycolysis. The aerob...

In 35 normal men, conventional and vectorial electrocardiographic items were studied after severe, anaerobic exercise over a recovery period of 8 min. The changes, especially of the T vector, are pronounced, but are different from those observed in coronary insufficiency. The hypothesis is advanced that the changes in anaerobic exercise are clue to general myocardial hypoxia, in contrast to the...

Background. Exertional fatigue, which frequently limits exercise in patients with chronic heart failure, is associated with early anaerobic metabolism in skeletal muscle. The present study was designed to examine the skeletal muscle metabolic response to exercise in this disorder and determine the relation of reduced muscle blood flow and skeletal muscle biochemistry and histology to the early ...

Background. Exercises with different intensities can cause changes in immune system factors and hormonal acute response. These changes may exceed the permissible limitations and weaken the system. Objectives. The purpose of this study was to compare the effect of an intensity aerobic and anaerobic training session on acute hormonal response and immune system factors. Methods. A total of...
