Figure 1: Experimental design. Rats were injected intraperitoneally with either placebo (grain oil) or vitamin E (100 mg/kg body mass of DL-α-tocopheryl acetate per day) for 5 consecutive days prior to examination (placebo-treated and vitamin-E-treated sedentary control groups) or exercise (placebo-treated and vitamin-E-treated exercised groups studied immediately post and 2 days post exercise), respectively. Downward arrows indicate the time of assessment.
