Característiques antropomètriques, composició corporal i somatotip per esports. Dades de referència del CAR de Sant Cugat, 1989-2013

Les tècniques antropomètriques, administrades amb el rigor que correspon, constitueixen un mètode repetitiu, sensible i discriminant per estimar els canvis de la composició corporal dels esportistes i són àmpliament utilitzades en l’àmbit de la medicina de l’esport. A partir de les mesures antropomètriques obtingudes en el seguiment dels esportistes del CAR de Sant Cugat, des de 1989 fins ara, s’han elaborat unes referències que són representatives del nivell nacional dels esports examinats i que corresponen als mètodes de Yuhasz, Faulkner i Drinkwater, el somatotip de Heath-Carter i el sumatori de 6 plecs, per tal d’oferir ajuda i orientació als professionals que utilitzin la cineantropometria

Krill-Oil-Dependent Increases in HS-Omega-3 Index, Plasma Choline and Antioxidant Capacity in Well-Conditioned Power Training Athletes

There is evidence that both omega-3 polyunsaturated fatty acids (n-3 PUFAs) and choline can influence sports performance, but information establishing their combined effects when given in the form of krill oil during power training protocols is missing. The purpose of this study was therefore to characterize n-3 PUFA and choline profiles after a one-hour period of high-intensity physical workout after 12 weeks of supplementation. Thirty-five healthy power training athletes received either 2.5 g/day of Neptune krill oilTM (550 mg EPA/DHA and 150 mg choline) or olive oil (placebo) in a randomized double-blind design. After 12 weeks, only the krill oil group showed a significant HS-Omega-3 Index increase from 4.82 to 6.77% and a reduction in the ARA/EPA ratio (from 50.72 to 13.61%) (p < 0.001). The krill oil group showed significantly higher recovery of choline concentrations relative to the placebo group from the end of the first to the beginning of the second exercise test (p = 0.04) and an 8% decrease in total antioxidant capacity post-exercise versus 21% in the placebo group (p = 0.35). In conclusion, krill oil can be used as a nutritional strategy for increasing the HS-Omega-3 Index, recover choline concentrations and address oxidative stress after intense power trainings
