Figure 1.  Relative HSP72 levels of the control (open bar) and the sprint-interval training (black bar) groups in the plantaris and soleus muscles. The data of HSP72 in the control (CON) group of the plantaris muscle was used as a standard value. Values are means ± SD (n = 8 for each group). * p < 0.05 significantly different from the CON group of the same muscle.
