Effects of RSV on functional parameters of physical performance. Physical performance tests were performed pre- and postintervention. Postintervention differences between treatment arms were compared using 1-way ANCOVA, implementing the corresponding preintervention variables as covariates. Postintervention data are presented as adjusted means ± SEs. (A) Post-treatment distance covered during the 6-min walk test per treatment arm. Data from 5 participants were omitted because of pain in the ankle, hip, or knee (n = 17 in the RSV arm; n = 19 in the placebo arm). (B) Postintervention time to complete the timed chair-stand test. Data from 2 participants were omitted because of pain in the ankle or hip (n = 19 in the RSV arm; n = 20 in the placebo arm). (C, D) Postintervention maximal isometric muscle extension and flexion strength measured by the Biodex system by isometric test. Data from 4 participants were not obtained because of technical problems (n = 18 in the RSV arm; n = 19 in the placebo arm). (E, F) Postintervention muscle isokinetic extension and flexion endurance, expressed as the slope of the trend lines measured by the Biodex system by isokinetic test. Data from 4 participants were not included because of technical problems, and those from 10 participants were not included because of no decline in muscle endurance over the 30 repetitions (n = 12 in the RSV arm; n = 14 in the placebo arm).
