Note. G-PAQ50+ = German Physical Activity Questionnaire 50+; BMI = body mass index; HGS = hand-grip strength; RDS = relative dynamic strength leg press; RIS = relative isometric strength leg press; MIS = maximum isometric strength chest press; MDS = maximum dynamic strength chest press; TIS = total isometric strength; TRIS = total relative isometric strength; GS = gait speed; RCS = repeated chair stands; SMI = skeletal muscle index. All bold values indicate strong relationships (r > .5) with SMI.
