Male mice were used from an animal model of 4 closed lines selectively bred for high voluntary wheel-running behaviour (HR) and 4 control lines bred without intentional selection, described in Swallow et al. Animals used in the current work were sampled from generation 37 at a mean age of 84 days (range = 79-86). For microarray analysis, we used gastrocnemius muscles (including both lateral and medial portions) from HRmini line #3 and HRnormal line #8 (n = 6, in each group). To obtain sufficient RNA, gastrocnemius samples of HRmini were pooled from left and right limbs from each animal, whereas HRnormal gastrocnemius was sampled from either left or right limb only.
