Specific force of the rat plantaris muscle changes with age, but not with overload.
Age and overload effects on the specific force of the rat plantaris muscle were investigated. The specific force was affected by age, but not by overload, inducing a 30% hypertrophy, at any age. The relative amount of non-contractile tissue only minimally affected the conclusions.
