Abstract

The purpose of this study was to test the hypothesis that older persons can minimize the reduction in physical fitness with aging if they start training before approximately 50 years of age, beyond which strength decline has been reported to become more pronounced. Maximal values for isometric strength, dynamic strength and speed of movement of the biceps brachii and quadriceps muscles, back-lift strength, and predicted oxygen uptake were measured in 39 male subjects who were 60-68 years old. Four groups were studied: T26, T45, T56, and untrained. The T26 group had been training (jogging 10 km/day, 5 day/wk at 10 km/h) since before their mid-thirties (mean 26 years), the T45 group since their forties (mean 45 years), the T 56 group since their fifties (mean 56 years), and the untrained group had never taken part in any systematic training. Collectively, the T26 and T45 groups had significantly higher values for muscle strength, speed of contraction, and VO2max than the T56 and/or untrained group(s). However, no differences were observed between the T26 and T45 groups. The results support a relation between the starting age of training and the age-dependent decline of physical fitness. Thus, the hypothesis is accepted. Verf.-Referat
