Both muscle strength and peak contraction velocity decline, in some muscles even from the age of 20

[8, 15, 16 17, 22, 23, 26, 27, 28, 29, 30, 32, 36, 37]

The response to training is independent of age

[8, 9, 15, 17, 22, 23, 30, 32, 36, 37].

Loss of type-II fibres is greater than that of type-I

[15, 16, 22, 23, 26, 27, 28, 37].

Cytochrome oxidase deficient fibres appear later in increasing, but very small numbers

[8, 9, 10, 33, 35, 44, 52].
