Seguimiento de la masa grasa y masa magra por segmentos corporales (brazos y piernas) en futbolistas juveniles

The objective of this study was to evaluate the follow-up of fat mass and lean mass of the body segments of the arms and legs in young professional soccer players. A longitudinal study was held to 41 players (15.85 ± 0.98 years old), performing an initial measurement (MI) and after 6 months a final measurement (MF), using the dual absorptiometer x-rays equipment (DEXA). The program SPSS t-student test (version 21.0) was used. Total lean mass of the arms had a significant increase (p < 0.05) from the MI to the MF, just like the left leg (p < 0.05). The differences in changes in lean mass in the legs increases are due for being a sport of aerobic demands and requirements of physical abilities of strength and speed.
