Effect of the minor allele of rs10783846 on body composition and strength in females and males at baseline.
CONTRACTION
BMI: body mass index, SARC-F: Strength, assistance with walking, rising from a chair, climbing stairs, and falls questionnaire score, SPPB: Short Physical Performance Battery score: QMVC: Quadriceps Maximal Voluntary contraction. For normally distributed data values are given as mean ± SD and for data that did not show a normal distribution values are median (interquartile range). Body composition measurements were not available for 1 male. QMVC measurements were not available for 1 female and 6 males. 6MW distance was not available for 1 male.Given the difference in height between the genotypes, we investigated the associations of limb muscle and fat mass with height. In males, leg and limb fat mass were weakly associated with height (r = 0.31, p = 0.025 and r = 0.30, p = 0.032 respectively) but there was no significant association between arm fat mass and height (r = 0.21, p = 0.145) nor were leg or arm fat associated with height in females (
