Physiological Alterations Observed in Young Competitive Swimmers During Three Years of Intensive Training.
Zauner, Christian W.; Benson, Norma Y.
This investigation sought to determine whether the excellent performer evolves from typical material through training or if he brings facilitating characteristics with him to practice on the first day. Subjects were highly successful AAU age-group competitors who had invested at least 50 percent of their lives in swim training. These seven female and eight male child swimmers (active in a year-round training program) were measured for maximal oxygen consumption (VO2 max), physical work capacity when the heart rate is 170 beats/minute (PWC 170), forced vital capacity (FVC), and body surface area (BSA). Measurements were done in early fall 1973, 1974, and 1975 following termination of the previous summer's meet season. Data evolving from the measurement of each parameter were analyzed with a two-way analysis of variance. It was concluded that as an outcome of training, young athletes show progressive increase in VO2 max and PWC 170. Furthermore, the FVC may be increased beyond expectations through prolonged intensive training in childhood. This latter phenomenon might be a function of increasing numbers of alveolar sacs. Tables are included. (MM)
