Efek suplementasi kalsium terhadap kebugaran dan profil kesehatan pada atlet Tarung Derajat

Abstract

Calcium is the main mineral that is needed by athletes for bone strength, joint, and muscle contraction during exercise. Strenuous and prolonged exercise will progressively increase calcium requirements. This inadequate calcium intake is having an impact on hypocalcemia and increasing the risk of sports injuries. The purpose of the study was to analyze the effect of calcium supplementation on fitness and health in Tarung Derajat athletes. The research design was experimental (pretest-posttest without control group design). A total of 21 Tarung Derajat athletes, aged 18-25 years, male and female were the subjects. The examination was physical fitness, anthropometric values, and blood pressure to determine the health profile, and blood calcium. The intervention was a calcium tablet, a dose of 1x1000 mg/day, given after dinner, and for 35 days. The results found that the number of female athletes with hypocalcemia decreased by 50%, from 44.44% (before) to 22.22% after calcium therapy. Physical fitness increased (p<0.05), but there was no change in weight (p>0.05), body mass index (BMI) (p>0.05), blood pressure (BP) (p>0.05) ) and calcium levels (p>0.05) after calcium supplementation. Conclusions: supplementation of calcium tablets decreased the amount of hypocalcemia in Tarung Derajat female athletes, increases physical fitness, does not significantly increase calcium levels but otherwise does not affect anthropometry (body weight and body mass index), and blood pressure in Tarung Derajat athletes.
