| Annotation | Physical training may be able to arrest or reverse age-related loss in strength and muscle fibre. This study's purpose was to determine the effects of long-term (50-week) physical training on healthy older women (age range 65-86) on maximal oxygen consumption (VO2max), thigh strength, and vastus lateralis fibre morphology. Subjects volunteered to be in either exercise (Ex; n=17) or control (Con; n=10) group. Con subjects were 34% less active in winter than in summer; Ex subjects maintained their summer activity level on exercise days in winter. Initial, intermediate (20 week) and final measurements were made for isokinetic knee extension/flexion strength; other measurements were made only at the start and end of the study. Both groups gained in leg strength during the summer (Ex +6.5%; Con +7.8%); in winter the Ex group maintained leg strength and the Con group declined 12.2%. The fast-twitch muscle fibre area increased 29% in the Ex group and declined 26% in the Con group. VO2max increased only in the Ex group (16%). Thus healthy older women can increase aerobic capacity, leg strength and muscle fibre area with a long-duration, combined aerobic-resistance exercise programme. (RH). |
