The Effects of Standardized vs Individualized Seat Height on 1-minute Sit-to-stand Performance

University of Zurich30 enrolled

Overview

The 1-minute sit-to-stand test (1MSTS) is a widely used functional capacity test and has promising predictive potential. Current standards of practice suggest the use of a chair with a standardized height. However, this practice makes the test more demanding for taller individuals than for shorter individuals. This implies over- or underestimation of functional capacity depending on body morphology. Therefore, the aim of this study is to investigate the influence of knee joint angle, femur length and bodyweight on the 1MSTS performance in healthy subjects with different morphology.

This is a randomized cross-over trial with the participants performing both procedures twice in one visit. Sufficient breaks in between the tests is granted.
