V. Melo Ruiz Ann Nutr Metab 2011;58(suppl 3): p214
Introduction: It is important to evaluate the body composition
of athletes in sports since it is known that exercise has a significant
effect on athletic performance and has a potential to alter the body
composition.
Objectives: . The purpose of this study is to assess the effect of
chromium picolinate and L carnitina on body composition of athletes
with a specific diet and training.
Method/Design: A study to explore the efficacy of chromium
picolinate and L carnitina supplementation in 24 athletes male and
female throughout 12 weeks; 12 of them with intake of 100 μcg/day
of chromium picolinate and 1 g/day of L carnitina and the other 12
with placebo, both groups with a diet of 50 kcal/kg of athletes weight,
distributed in 70% carbohydrates, 1.8 g/kg athlete weight of proteins
and 20% lipids approximately and a training of 18 h/week. The body
composition measurements and evaluation of athletes was performance
out by bioelectrical impedance analysis, skin fold thickness and
anthropometric parameters.
Results: Data recorded gave the following results; athletes with
diet and placebo, had a weight loss of 450g increase 1.24% body fat
and 0.69% muscular mass; group with diet and ergogenetic supplement
gain 100 g/weight, loss 2.34% body fat and increased 1.83%
muscular mass.
Conclusions: In conclusion chromium picolinate increase lean
body mass and decrease percentage of body fat. L carnitine regulate
glucose levels and protect proteins, therefore the ergogenetic supplement
combined with a balanced diet and adequate training lead to
improve condition and regulate body composition of athletes.
