a
Responses are recorded in left gastrocnemius muscle,
b
responses are recorded in left plantaris muscle.
c
Values are means ±s.d.,
d
individual values.
*
Timing effect, P < 0.05.
**
Time by condition effect, P < 0.05. Individual values obtained at 4 and 5 weeks are within mean ± 2.5 s.d. of control values.
