The present study investigates the effect of two anti-oxidant supplements including vitamin E and Q10 coenzyme on the maximum strength, flexibility and power of Karateka girls. 36 karate player girls between 15 to 17 years old from the statistical population (N=275) have voluntarily enrolled in the present study and were randomly placed into 3 groups (vitamin E supplement group, Q10 coenzyme supplement and control group). The experimental groups of 12 subjects: experimental group1 consumed vitamin E supplement (400 IU daily) and experimental group 2 consumed Q10 supplement coenzyme (100 mg daily) for 14 consecutive days with dinner while the control group consumed no supplementary or placebo. The tests related to maximum strength, flexibility and power were hold before and after consuming supplement. Data were analyzed by the use of one-way ANOVA for measuring the difference between groups and Tukey follow up test for determining the difference between groups at significant level of α ≤ 0.05. The findings indicated that no significant difference was seen in maximum strength of muscles of back and lower body, flexibility, peak power and average power in all three groups, but just the maximum strength of lower body muscles significantly increased after consumption in two supplementary group rather than control group (p ≤ 0.05). It can be concluded that 14 days of consumption vitamin E supplement and Q10 coenzyme can be effective on the maximum strength of lower body muscles in female karateka.
