Study objective: The aims of this work were to determine (1) whether patients with COPD have impaired skeletal muscle performance (ie, maximal strength and endurance) compared with healthy subjects, and (2) whether the level of physical activity, body composition, and lung function are related to skeletal muscle performance in COPD patients. Methods: Seventeen COPD patients and eight healthy ag...

This activity been man since its origin. As it appeared Nordic countries more than hundred years ago perform an outdoor physical intellectual potential promote aerobic endurance university stude...

The purpose of this study was to investigate the aftereffects of self-generated mental imagery of an effortful task on physical self-control endurance and muscle fatigue. Participants performed two isometric handgrip endurance trials (50% of maximum contraction) separated by either an imagery manipulation or a quiet rest period. The imagery group showed greater negative changes in endurance per...

INTRODUCTION Clinical practice and the results of some studies may indicate that physical exercise in the form of endurance training may influence the development of atrial fibrillation (AF). The aim of this paper is to evaluate the scientific background for the hypothesis that there is a connection between physical activity and AF. MATERIAL AND METHOD This paper is a review article based on ...

Physical fitness can be defined as a set of attributes that allows the ability to perform physical activity. The attributes or components of fitness were identified by testing large numbers of individuals on physical performance tests (e.g., sit-ups, push-ups, runs, pull-ups, rope climbs, vertical jump, long jumps), and using statistical techniques to find tests that seem to share common perfor...

BACKGROUND AND OBJECTIVE For athletes, the main purpose of nutrition is to ensure the compensation of increased energy consumption and the need for nutrients in the athlete's body, thereby enabling maximum adaptation to physical loads. The aim of this study was to determine the habits of highly trained endurance athletes depending on sports type, sex and age in order to improve the planning and...
