Data are presented as mean differences (95% CI). The mean differences of all outcomes were calculated with two different linear regression models (Model 1: adjusting for the experimental condition, sequence period and subject; Model 2: adjusting for the experimental condition, knee angle, sequence period and subject). The analysis of heart rate data was performed with 46 subjects. Limits of agreement of mean differences in the two experimental conditions (1MSTSIND and 1MSTSSTD) (1.96×sd). STS: sit-to-stand; SpO2: oxygen saturation.
