The Effect of Selected NaHco3 Supplimentation on Acid- Bace status and Performance Time of Wrestlers During Heavy Intermittent Work

The Purpose of this study was to determine the effect of the ingestion of Nahco3 on Acid-Base balance and performance time in trained male wrestlers during intermittent running to exhaustion. Twenty healthy male wrestlers (17-27 & 60-78 Kg body weight) were participating in exercise training protocol. Subjects were assigned either supplementgroup (n=10) and placebo group (n=10). The supplement group was received Nahco3 in form one capsule (0.065 gr/Kg body weight) while the placebo group was received the same amount of bran rice one hour before the test. Subjects were performed a test on a motor driver treadmill at speeds, 8, 12 and 14 Km/ h and incline 10% grade. Eachphase was consisted of 2 minutes of running which followed by 30 sactive resting period at speeds 4 Km/h (in phase 1), 8 Km/h (phase 2) and in the last phase (phase 3). Subjects ran until to exhaustion. Blood sample was taken before and immediately after the test. Plasma lactate, Ph, Pco2, Po2 and Hco3 were measured. A paired andunpaired t-test were used for data analyzing and significant level was considered at P􀂔 0/05. The results showed that a change in blood gase was not significant. However a decrease in plasma lactate and an increase in running time to exhaustion were observed. It seems that NaHco3 supplementation before the exercise increase running time toexhaustion via reducing the appearance of lactate into blood.
