Reliability of Lower Extremity Muscle Power and Functional Performance in Healthy, Older Women
Table 2
Muscle torque (n = 14), power (n = 13), and functional performance (n = 16) for time points 1 (week 0), 2 (week 9), and 3 (week 15).

aData are mean (SD), except for the SPPB, where medians (min, max) are displayed since data were not normally distributed; repeated measures ANOVA used to test means across time points, except for the SPPB which was tested using Friedman test; ES = Cohen’s d effect size for time points 1 and 2 and 1 and 3, except for the SPPB which was calculated using z/√N for nonparametric data [24]. KET: isometric knee extension torque; KEP: knee extension power; KFP: knee flexion power; PFP: plantar flexion power; DFP: dorsiflexion power; SPPB: Short Physical Performance Battery; 4 MUP: 4-meter usual pace walk; 4 MFP: 4-meter fast pace walk; 400 MW: 400-meter walk; 5 CS: 5 chair stands; 30 sCS: 30-second chair stands; SCUP: stair climb usual pace; SCFP: stair climb fast pace; SCP: stair climb power for the SCFP; . For the 5 CS and 30 sCS, time point 3 was significantly different from time point 1. |
