Abstract :
The aim of the current research was to the effect of short-term creatine supplementation on lactate dehydrogenase after a session of intense aerobic and anaerobic activity in active women. For this purpose, 40 active women of Damghan city with an average age (25 ± 5 years), weight (63 ± 7 kg), height (165 ± 7.5 cm) and body mass index (25 ± 5 kg/m2) voluntarily participated in this research. The research was of a semi-experimental type, and the subjects were randomly divided into four groups iaerobic supplementation (10 people), aerobic placebo (10 people), anaerobic supplementation (10 people), and anaerobic placebo (10 people) and studied. The supplement group consumed creatine every day (0.3 grams per kilogram of body weight) in 4 meals (8, 12, 16, and 20 hours) for 7 days; the placebo group consumed the same amount of corn powder. The aerobic group performed the Bruce test before and after completing it, and the anaerobic group performed the Wingate test. Blood samples were taken from the subjects after aerobic and anaerobic tests and after taking supplements and repeating the tests to measure lactate dehydrogenase (LDH). Index measurement was done using the relevant kits and with the help of an auto-analyzer, the analysis of variance test was used to analyze the data. The results of the research showed that there is no significant difference between the LDH level of the aerobic creatine group and the aerobic placebo group, as well as the anaerobic creatine group and the anaerobic placebo group, but the comparison of the LDH level of the aerobic creatine group and the anaerobic creatine group showed that there is a significant difference. In other words, taking a creatine supplement along with a session of acute aerobic activity led to a greater decrease in LDH than taking this supplement after anaerobic activity. In general, it can be concluded that creatine monohydrate loading does not significantly reduce LDH levels.
