Abstract:

The intake of supplements with creatin monohydrate in high performance athletes has been used to stimulate or increase ergogenic capacity in high-intensity, short-duration exercise. However, the increase in performance has not been sufficiently demonstrated and its use has been the source of undesirable effects. Material and methods. Twenty-eight high performance rugby players, with an average age of 26.31 ± 3.48, were studied. Of these, 22 (Group A) ingested doily, for one week, 20 gr. of creatin, followed by a maintenance dosis of 5 to 10 gr./day for 30-60 days. The remaining 6 players (Group B) did not receive any supplement. The modified Anthropometric Fractioning method was used to make the evaluation, which allows for the classification of the organism in 5 components: Fat Mass (FM), Skeletal Mass (SM), Muscular Mass (MM), Visceral Mass (VM) and Residual Mass (RM). Twenty-five body surface measurements were taken (7 fat folds, 8 bone diameters, 7 girths, standing and seated measurements and body weight). The data was then processed with the ENFA™ program. Body mass and caloricproteic reserve (CR and PR) were evaluated (NV = 0.85-1.47 and 2.15-2.72, respectively), and muscular mass was correlated with skeletal mass in the total of the studied population (r) and (p). The remaining data was treated statistically by a "t" test, with a p ≤ 0.05 taken as significant. Results: The comparative values for both groups (A vs. B) are: MM (41.03 ± 5.23 vs. 40.42 ± 5.15 Kg.)(p = 0.80); SM (16.67 ± 2.09 vs. 16.96 ± 2.14 Kg.) (p = 0.76); FM (10.78 ± 3.21 vs. 10.34 ± 2.92 Kg.) (p = 0.76); VM (19.73 ± 3.23 vs. 19.83 ± 2.05 Kg.)(p = 0.94); RM (8.52 ± 2.3 vs. 3.52 ± 1.27 Kg.) (p = 0.000); CR (0.64 ± 0.18 vs. 0.61 ± 0.17) (p = 0.71); PR (2.46 ± 0.18 vs. 2.39 ±0.21)(p = 0.42). There was a good correlation (r = 0.83) between muscular mass and skeletal mass (n = 28). Conclusion: The intake of regular doses of creatin monohydrate in high performance athletes for a period of 30-60 days causes a significant increase in residual mass (hydric retention) in the extra-cellular space. This adverse effect should be taken into consideration at the time of its indication.
