Investigation of adaptive processes in child and adolescent swimmers. Acid-base parameters of swimmers and weight-lifters.
Acid-base parameters of adolescent swimmers (capacitive sport) and of adult weight-lifters (athletoid sport) were investigated before and after training in the submaximally trained phase of a year-round training period. In swimmers, training induced incompensated metabolic acidosis, which persisted at 10 min after the training. This acidosis showed no correlation to the blood lactate level. In weight-lifters, there was only a slight, compensated posttraining acidosis, which tended to decrease 10 min after the training. The weight-lifters had extremely high posttraining ammonia levels. It might be supposed that ammonia-genesis has a role in the compensation of exercise-induced acidosis in weight-lifters. The differences in acid-base status of swimmers and weight-lifters might be related to the different breathing mechanism needed for the two different sports.
