Abstract
The present study aimed to investigate the effect of creatine supplementation on selected biochemical indicators and anaerobic capacity among Olympic weightlifters at Badra Sports Club. Creatine is widely recognized as one of the most commonly used nutritional supplements for enhancing physical performance in high-intensity anaerobic activities. The significance of this study lies in examining the simultaneous effect of creatine on anaerobic capacity, as well as on biochemical markers related to liver and kidney functions and the levels of certain vitamins, in order to verify both its effectiveness and safety for weightlifters.
The researcher employed an experimental design using a single group with pre- and post-testing. The study sample consisted of eleven (11) weightlifters from Badra Sports Club. The research variables included anaerobic capacity, in addition to a set of biochemical indicators represented by liver enzymes (GOT and GPT), blood urea, serum creatinine, and the levels of vitamins A and D. Pre-test measurements for all variables were conducted prior to the initiation of creatine supplementation, followed by post-test measurements after four weeks of regular supplementation according to the recommended dosages, while maintaining the athletes’ regular training program.
The results revealed statistically significant improvements in anaerobic capacity in favor of the post-test measurements, indicating the effectiveness of creatine supplementation in enhancing anaerobic performance among weightlifters. Conversely, no significant differences were observed in the studied biochemical indicators, as creatine intake did not produce noticeable changes in liver enzymes, kidney function markers, or vitamin A and D levels. The study concluded that creatine supplementation is an effective means of improving anaerobic capacity without causing adverse effects on the biochemical indicators examined, thereby supporting its safe use within weightlifting training programs.
