Summary
Various aspects of neuromuscular, anaerobic, and aerobic performance capacity were investigated in four powerlifters, seven bodybuilders, and three wrestlers with a history of specific training for several years. The data (means ± SD) showed that the three subject groups possessed similar values for maximal isometric force per unit bodyweight (50.7±9.6, 49.3±4.1, and 49.3±10.9 N/kg, respectively).
However, significant (P<0.05) differences were observed in the times for isometric force production, so that e.g., times to produce a 30% force level were shorter for the wrestlers and bodybuilders (28.3±3.1 and 26.4±6.6 ms) than that (53.3±23.7 ms) for the powerlifters. Utilization of elastic energy by the wrestlers was significantly (P<0.05) better than that of the other two subject groups, as judged from differences between the counter-movement and squat jumps at 0, 40, and 100 kg's loads. No differences were observed between the groups in anaerobic power in a 1-min maximal test, but the values for \(\dot V_{O_2 } \) max were higher (P<0.05) among the wrestlers and bodybuilders (57.8±6.6 and 50.8±6.8 ml·kg−1·min−1) as compared to the powerlifters (41.9±7.2 ml ·kg−1·min−1). Within the limitations of the subject sample, no differences of a statistical significancy were observed between the groups in fibre distribution, fibre areas, or the area ratio of fast (FT) and slow (ST) twitch fibres in vastus lateralis. In all subjects the vertical jumping height was positively (P<0.01) correlated with the FT fibre distribution, and negatively with the time of isometric force production (P<0.05). Maximal force was correlated (P<0.001) with thigh girth. Muscle cross-sectional area did not correlate with mean fibre area. It was assumed that the selected aspects of neuromuscular, anaerobic, and aerobic performance capacity may be influenced by muscle structure, but also specifically and/or simultaneously by training lasting for several years.
