| Introduction: The aim of the present study wascomparison the effect of two short-term methods of loading sodium bicarbonate supplementation and exhau-stiveaerobic activity on the fatigue and biochemical indices of muscle injury in the youngactive men.
Materials & Methods: The 10 active men (age: 23. 3±1.3 years,height: 175±2.
8Cm, weight: 65±2.4kg) were randomly selected in a semi–experimental design in two different, short-term methodsfor loading sodium bicarbonate supplem-ent(inthe first method 0.03 g, and in the second method 0.05gr pereach kilogram of body weight). These supplements were dissolved in 250 ml of supplem-entarysolution and given to the subject-tsto consume bicarbonate solution. To calculate the blood variables (LDH, pH and lactate),blood samples were taken during two stages, before and after the test. The Exercise test included a GXT adjusted Bruce exercise test with the intensity 75% of maximum heart rate.Data were examined by Kolm-ogorov-Smirnov statistical test for being normal, and dependentstatistical t-test was used for data analysis bySPSS software.
Findings: The results indicated that the second loading method, incomparison with the first one, caused an increase in activity time, and an increase of 26 percent in PH level (p <0.028). Immed-iatelyafter activity,a significant differe-nce was observed between long and sh-ort terms loading in serum LDH indic-ator (p<0.041).
Discussion & Conclusion:In according to thefindings of present studythe second loading method prolongs the activity timeand also reduces the amount of muscle injuryby postponing the time to reach fatigue. |
