Acute Effect of Short-Distance Running on Bone Metabolism

Abstract

       This research aims to study the Acute Effect of Short-Distance Running on the Treadmill on Bone Metabolism in Early-Adult female by using a comparison of the step touching on the treadmill between 2,500 steps and 5,000 steps. The research had purposive selection that consists of 20 early-adult females aged between 18-21 with BMI less than 23 kilograms/M², without any osteopathy record or medical conditions, which affect the bone metabolism. This experimental research started by getting blood draws for the selective groups after 8 hour fasting to evaluate P1NP, OC, and CTX, and this selective group should not be on a period at that moment. The researcher divided the selective group into 2 groups of 10. The first group got the two-time blood draws within 30 minute difference without having any activities. The second group got the first blood draws before having short-distance running, and then ran with the speed at least 8 Km/hour, and once again got second blood draws immediately after the exercise finished. The researcher will compare the differences from the step count between 2,500 steps and 5,000 steps and this was repeatedly done after 1 week. The statistic formula used for this research is Average (X̅), Standard Deviation (S.D.), Two-way Multivariate Analysis of Variance with Repeated, and One-way Multivariate Analysis of Variance to find the variances following Tukey Statistic Test with specified the statistical significance at 0.05.   

       The research found that the short-distance running with 5,000 steps touching on a treadmill caused the decreasing of P1NP, OC, and CTX significantly while the 2,500 steps running caused the decreasing of only P1NP and CTX. The research also said that the 5,000 step-running got higher OC value than 2,500 step-running with statistical significance value 0.05. This came to the final conclusion that both activities could effect to the Bone Remodeling in Early-Age Female.
