The Hepcidin-25/Ferritin Ratio Is Increased in University Rugby Players with Lower Fat Mass.

Hepcidin-25 is suggested as a surrogate iron status marker in athletes who show exercise-induced anemia; however, the implications of hepcidin concentration in this population remain poorly understood. This study aimed to investigate the relationship between hepcidin and body fat levels in rugby football players. We included 40 male university rugby football players (RUG) and 40 non-athlete controls.

Nonalcoholic Fatty Liver Disease in University Rugby Football Players.

Physical activity improves various metabolic disturbances. The effect of physical activity on non-alcoholic fatty liver disease (NAFLD) has not been defined, particularly in athletes who are able to consume a diet to increase body mass. The aim of this study was to evaluate the prevalence of NAFLD and associated factors of NAFLD among male university rugby football players [ = 69, 37 forwards (FW) and 32 backs (BK)], relative to age-matched controls (CON; = 29).

ACTN3 GENE R577X POLYMORPHISM ASSOCIATED WITH HIGH-DENSITY LIPOPROTEIN CHOLESTEROL AND ADIPONECTIN IN RUGBY PLAYERS.

Objective: To determine the relationship between the R577X polymorphism of the α-actinin-3 (ACTN3), which may play a role in the individual differences observed in the effects of exercise on health benefits and antiatherogenic markers (i.e., high-density lipoprotein cholesterol [HDL-C] and adiponectin) in athletes.
