Swimming performance is influenced by various factors, such as, anthropometric variables, body composition, somatic trait, and strength. Different competitive swimming distances require swimmers to adopt different strategies, techniques, and physiological demands. The objective of this study was to compare isokinetic strengths and energy systems between short (50 m.) and middle distance (400 m.) swimmers. 36 national swimmers were recruited to the study. The study was divided into 4 groups (male/female × short/middle) with 9 swimmers in each group. Each subject was tested for muscle strengths of 4 joints, which were, ankle, knee, shoulder and elbow. The muscle strengths were assessed using isokinetic dynamometer. Wingate and Bruce protocols were used to assess anaerobic and aerobic energy systems. Two-way ANOVA was employed to compare muscle strengths and energy systems. The results showed that gender main effect was more crucial than distance main effect. Male swimmers were stronger and had better anaerobic and aerobic energy systems than female swimmers, while short distance swimmers had similar muscle strengths, anaerobic and aerobic energy systems to middle distance swimmers. The results showed that only right shoulder extension and right ankle extension, short distance swimmers were different from middle distance swimmers. [ABSTRACT FROM AUTHOR] |
