Muscle fibre adaptations, strength and power development during strength and/or endurance training in 40 to 65-yr-old women

The purpose of the present study was to examine muscle fibre composition and fibre size adaptations following 6 months of resistance and endurance training in 40 to 65-yr-old women (mean age 52 ±7 yr), and the changes in neuromuscular performance. The experimental groups were composed of strength...

description The purpose of the present study was to examine muscle fibre composition and fibre size adaptations following 6 months of resistance and endurance training in 40 to 65-yr-old women (mean age 52 ±7 yr), and the changes in neuromuscular performance. The experimental groups were composed of strength training (S) group (n =27), endurance training (E) group (n = 27), concurrent S and E (C) group (n = 25) and control group (n = 20). Maximal concentric and isometric strength showed similar significant increases in the S (9.8 and 18.4%, p < 0.001) and C (12.1 and 21.0%, p < 0.001) groups with slight increases in E (1.9 and 8.8%, p < 0.05). Maximal power increased to a similar extent in S (9.9%, p < 0.01) and C (12.5%, p < 0.001), however, the E and control groups showed significant decreases in power (-3.5 and -6.1%, respectively, p < 0.05). All training groups decreased their type IIB myofibre content and type IIA percentage increased significantly in the S group. Muscle fibre size remained statistically unaltered in S and C for each muscle fibre subtype, whereas the size of type IIA and type I showed a significant increase in the E and control groups, respectively. The present data in middle-aged women showed that the S and C groups expressed similar neuromuscular adaptations in all variables measured. However, the selected differences observed by the correlations between type IIA muscle fibre adaptations and the changes in strength in the S and C groups suggested somewhat dissimilar mechanisms of adaptation, when training S alone or S concurrently with E.
