TheEffect of two Different Methods of LoadingSodium Bicarbonate Supplementation along with Aerobic Exercise on Indices of Muscle Injury in Young Men

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. 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. 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 & 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.
