The Effect of Moderate Intensity Physical Activity on Ureum and Creatinine Serum in Untrained Male Students

Abstract

Exercise induces profound changes in the renal hemodynamics and protein excretion. Ureum and creatinine levels can be used to assess whether renal function is still working properly or not. Ureum and creatinine levels can be affected by physical activity because ureum and creatinine are products of protein metabolism in skeletal muscle. The purpose of this study was to see the effect of moderate intensity physical activity on ureum and creatinine serum in untrained male students. This research is a preexperimental study with the design of one group pretest-posttest. The sample in this study were ten untrained male students taken by purposive sampling. Physical activity protocol is running on a treadmill for 60 minutes with an intensity of 60-75 percent of maximum heart rate reserve (MHR). Blood samples were taken to measure ureum and creatinine before and after the physical activity. Data were analyzed by paired T-test and Wilcoxon test. This study showed that the average results of ureum had a significant decrease and mean results of creatinine showed a significant increase. Based on these results we can conclude that the moderate intensity of physical activity on a treadmill reduces ureum and increases creatinine in untrained male students.
