The purposes of the study were to 1) test the effects of one week of resistance training and vitamin E supplementation on blood glutathione (GSH), malondiadehyde (MDA), and creatine kinase (CK), 2) investigate the effect of 7 weeks of resistance training and vitamin E supplementation on GSH, MDA, CK, and muscular strength, and 3) compare with the adaptive effects of plasma GSH, MDA, and CK between one week and 7 weeks of resistance training and vitamin E supplementation in males.
Twenty-six college male volunteers were randomly assigned into three groups including vitamin E supplementation plus resistance training (EG), resistance training only (RG), and control (CG) group. The subjects of the RG performed 10 exercises, 8 RM, 3 sets, 3 days/week for 7 weeks. The EG took 400 IU vitamin E per day and plus the same volume of resistance training of RG. Blood samples were collected at pre (A), immediately after one week of training (B) and after 7 weeks of training (C), and two days after the completion of all resistance training (D). Two-way ANOVA mixed design and one-way ANCOVA were used to test the difference among three groups on GSH, MDA, and CK at different periods. Scheffe post hoc comparisons were used to test the difference between groups. Paired-t tests were used to test the dependent variables between A-D and B-C period of blood sample obtained at the same group. The statistical significant level was set at .05. The findings were as follows:
1. The effect of one week of resistance training:
(1) No significant differences were found among three groups on plasma GSH; however, the EG had tendency of lower plasma GSH than that of the RG.
(2) No significant differences were found among three groups on plasma MDA.
(3) The RG had significantly higher (P< .05) plasma CK level at B period than the CG. No difference was found between EG and CG.
2. The effect of 7 weeks of resistance training:
(1) The plasma GSH level on EG was significantly lower (P < .05) at period of C and D than those of RG and CG. There was no difference of plasma GSH level between EG and CG.
(2) No difference of the plasma MDA level among three groups was found.
(3) No difference of the plasma CK level among three groups at periods C and D was found.
3. The effects of resistance training between one week and 7 weeks:
(1) The effect on plasma GSH:
A. The CG decreased (P < .05) between period of A and D. The EG at period of C was lower (P < .05) than EG at period of B. No difference between RG and CG was found.
B. No significant difference was found on the plasma GSH level among three groups after a week of resistance training; however, the GSH level of EG was significant lower (P < .05) than the RG and CG after 7 weeks of resistance training.
(2) The effect on plasma MDA: No difference among three groups between A and D period, B and C were found.
(3) The effect on plasma CK:
A. EG at period A was lower (P < .05) than that of at period D. No difference was found among three groups.
B. The plasma CK level of RG after one week of training was significantly higher than that of seven weeks of training (P < .05). No significant difference was found between EG and CG was found.
C. EG had a lower of plasma CK at B period; however, EG had no such a lower tendency at period C.
(4) Muscular strength significantly increased (P < .05) on the upper and lower body after 7 weeks of resistance training. Although no significant difference was found among groups of muscular strength, the Vitamin E supplementation group had better tendency on the improvement of muscular strength.
Based on the results, it was concluded that resistance training had no effects on the changes of the plasma GSH level. Furthermore vitamin E supplementation decreased plasma GSH after 7 weeks of resistance training. There was no lipid peroxidation since no plasma MDA changes occurred; meanwhile, resistance training with vitamin E supplementation did not change plasma MDA level. In addition, the blood CK was increased after a week of resistance training which support the theory that micro muscular trauma had occurred; however, long-term resistance training did not change the level of CK. Lastly, the resistance training improved muscular strength while training with vitamin E supplementation seems to have better results on strength increase.
