ABSTRACT

Park J.B. Correlation among anaerobic power, muscle morphology, oxygen consumption capacity, and sprint swimming time in sprint swimmers. Exercise Science, 11(2): 495-504, 2002. The intent of the present study was to evaluate correlation among anaerobic power, muscle morphology, aerobic capacity and the record of short sprint swimming (50m) in sprint swimmers. Twelve sprint swimmer (19.9±0.9 years) volunteered in the study. Sprint swimming time (50m), anaerobic power (30sec sprint using upper body), oxygen consumption (V2max test, during sprint) performance tests were performed. and muscle biopsy samples (deltoid) were also taken to evaluate muscle morphology.The results showed a relatively low negative correlation between 50m swimming time and anaerobic power. TypeⅡ fiber distribution of the deltoid muscle was positively correlated with 50m swimming time(p.>05). On the other hand, a negative correlation was found between typeⅠ fiber distribution of the deltoid muscle and anaerobic power(p.>05). Oxygen consumption during anaerobic power test was negatively correlated with 50m swimming time(p.>05). The obvious results may reflect an importance of the characteristic of aerobic capacity even in a sprint exercise.

Key words: muscle morphology, anaerobic power, swimming time
