Association between Nutritional Intake Status and Appendicular Muscle Mass in Female University Students with a High Physical Activity Level*

This study investigated the association between nutritional intake and indices of muscle mass or strength in 104 female Japanese university students who participated sports activities during their junior senior high school periods had a current physical activity level (PAL). Body composition was measured by bioelectrical impedance method, appendicular (AMM) skeletal index (SMI) were evaluated as mass. PAL estimated using factorial method status food frequency questionnaire based on groups (FFQg). Grip an strength. According to criteria for diagnosis sarcopenia, four participants low one also grip Although there no significant differences body size with versus SMI, SMI significantly higher percentage fat (27.7 ± 4.7% vs. 23.3 4.1%), lower AMM (16.0 1.4 kg 20.6 1.5 kg), total energy (1770.4 386.5 kcal/d 2017.1 389.9 kcal/d), protein (57.3 15.0 g/d 67.0 14.2 g/d), well tendency have carbohydrate (239.6 49.3 268.1 54.4 than those SMI. These results indicate that even some might dietary intake, mainly carbohydrate.
