The purpose of the study is to investigate the nutritional effect in the exercise of the β-alanine by comparing the causes of blood fatigue to the MDA concentration, the indicator on the lipid peroxidation by the oxidative stress for a total of 4 times including before the experiment, right after the exercise to reduce the weight, 1 hour after the exercise and 24 hours after the exercise bewteen the Wβ (β-alanine injected) and the WP (placebo injected) groups of university male judo athletes. The β-alanine was injected by calculating individual dose of 6g per 100kg weight for 3 times a day for 4 weeks, as well as the short-term weight loss period of 6 days. There is no difference in the blood lactate between the groups under the 2 injection conditions and only WP group shows significant difference right after the weight loss exercise and 24 hours after the exercise (p < 0.05). There is no difference in the blood phosphorous changes between the groups under 2 inejction conditions and both groups show significant increase 24hours after the weight loss exercise (p < 0.05). No significant difference in the groups, periods and interaction is found in the blood ammonia (p < 0.05). There is no difference between the groups in the blood MDA under 2 injection conditions and both groups show significant increase 1 hour and 24 hours after the weight loss exercise (p < 0.05). Therefore, the β-alanine injection is effective in prohibiting the lactate accumulation by the short-term weight loss exercise but does not show positive effects in defending the tissue damages and oxidative stress. |
