  1. Data are presented as mean (standard deviation). Paired sample t test used for CPET variables (n=42) and sit-to-stand (n=27) variables and linear mixed models used for 6MWD (n=43) and handgrip strength (n=43). Abbreviations: 6MWD 6-min walk distance, CPET cardiopulmonary exercise test, AT anaerobic threshold, VO2 peak volume of O2 consumed at peak exercise, BSA body surface area
