Fig. 4.

Peak soleus twitch tensions between 5 and 30 min at 20 °C and 42 °C. Twitch tension (P _t) values were obtained from muscles twitched at 5-min intervals. Significant differences were observed for all groups between 5 and 30 min except for the C20 group. At 30 min, significant differences were detected between muscles stimulated at 20 °C or 42 °C temperatures. Error bars denote SEM. An asterisk denotes significant difference (p < 0.05) between temperature groups while number sign denotes differences between 5 and 30 min with groups
