| Research Abstract |
The aim of this study was to clarify the effect of ageing and exercise training on α-actinin-3 in rat skeletal muscle. Our results suggest that ageing-induced muscle atrophy and fast-to-slow shift of the plantaris muscle accompanied with decrease in α-actinin-3, suggesting salcopenia might be associated with α-actinin-3.However, endurance exercise that we selected did not alter α-actinin-3 expression. Thus, endurance-type exercise may not be effective as intervention to α-actinin-3.
