Evaluation of body mass composition in high performance rugby players with and without intake of creatin monohydrate
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 undesir...

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.
