Abstract
El cacao rico en flavonoides tiene efectos positivos en el metabolismo de lípidos y podría mejorar el rendimiento en atletas a través de la mejora de su composición corporal. Se llevó a cabo un estudio de intervención controlado por placebo en atletas de resistencia que recibieron 5 g de cacao al día (425 mg de flavanoles) durante 10 semanas. Se midió ingesta dietética, composición corporal, rendimiento deportivo y niveles plasmáticos de follistatina, miostatina y leptina. La ingesta de cacao redujo significativamente el porcentaje de grasa corporal (p = 0,020), específicamente en el tronco (p = 0,022), área visceral (p = 0,034) y miembros inferiores (p = 0.004). La reducción de la masa grasa corporal fue acompañada por un aumento de follistatina plasmática y una disminución de leptina, mientras que los niveles de miostatina se mantuvieron sin cambios. La ingesta de cacao redujo el porcentaje de grasa corporal de los atletas, sin ningún impacto en el rendimiento de los atletas.
Flavanols-rich cocoa has positive effects on lipid metabolism and might enhance the performance of athletes through an improvement in their body composition. To test this hypothesis a placebo-controlled intervention study in training endurance athletes who received 5 g of cocoa daily (425 mg of flavanols) for 10 weeks was performed. Dietary intake, body composition, exercise performance, and plasma levels of follistatin, myostatin, and leptin were measured. Cocoa intake significantly reduced body fat percentage (p = 0.020), specifically in the trunk (p = 0.022), visceral area (p = 0.034) and lower limbs (p = 0.004). The reduction in body fat mass was accompanied by an increase in plasma follistatin and a decrease in leptin, while myostatin levels remained unchanged. The intake of cocoa reduced the percentage of body fat of athletes, without any impact on athletes' performance. The change in fat body composition did not improve athletes' performance.
