摘要: Declines in muscular strength resulting from reduced neural activity may influence the reduction aerobic capacity older men. However, there has been little investigation into relationship between and economy of movement during exercise elderly subjects. Thus, purpose this study was to investigate possible strength, performance, neuromuscular Twenty-eight aged men (65 ± 4 years old) were evaluated dynamic (1 repetition maximum test), isometric (maximal voluntary contraction), rate force development. Peak oxygen uptake, maximal workload, ventilatory threshold determined a ramp protocol on cycle ergometer. Throughout same protocol, (electromyographic signal) vastus lateralis measured. Significant correlations found cardiorespiratory fitness, (r = 0.43-0.64, p < 0.05). Our results suggest that are associated with aging.
