摘要
To examine the effects of specific concentric and eccentric training on muscular strength following an initial standardized period oi excessive training, shoulder extensors and flexors were tested. The shoulder is a joint particularly susceptible to injury and requires a specific strength training program. For a period of 12 weeks, subjects performed training including concentric and eccentric actions. Thereafter they were divided into three groups that performed specific 12-week programs, including either concentric (C-E/C), eccentric (C-E/E), or a combination of both concentric and eccentric exercises (C-E/C-E). Following the initial period of training, significant increases (p <0.05) in performance were observed for all experimental groups. The C-E/C group showed significant increases (p <0.05) in performance after 24 weeks of training, especially at high concentric angular velocities. However, the C-E/E group showed significant increases (p <0.05) only in their eccentric moments. No significant differences were noted for the C-E/C-E group. These findings seem to partly confirm the mode-specificity principle, as only the concentric-specific training program improved concentric and eccentric strength. Moreover, the velocity-specificity principle was strongly supported.
