BMI: body mass index, SPPB: Short Physical Performance Battery score: QMVC: Quadriceps Maximal Voluntary contraction. Normally distributed data are presented as mean ± SD with significance of differences determined by t-test. Non-parametric data are presented as median (inter quartile range) and the significance of differences was determined by Mann Whitney U testIn men, presence of the minor allele was associated with higher QMVC both as a raw value (II/ID median 18.0 kg IQR (14.5, 21.6) vs DD 13.2 kg (10.5, 15.9) p = 0.028
