Age And Gender Differences In Hip Extension And Flexion Torque Steadiness, Iveta Grunte
Age And Gender Differences In Hip Extension And Flexion Torque Steadiness, Iveta Grunte
All ETDs from UAB
Purpose of this study was to compare age and gender differences in hip extension (HE) and flexion (HF) relative (5, 25, and 50% of maximal voluntary contraction [MVC]) and absolute (25 Nm) torque steadiness measured as standard deviation (SD) and coefficient of variation (CV) of torque fluctuations, and torque accuracy (TA). MVC and steadiness were assessed for 20 young (24.0 + 2.2 yrs) and 11 older (65.4 + 4.5 yrs) men and women. MVC was lower for HF, but HE had greater torque fluctuations. For HE, CV of 5% MVC was greater for older compared to young adults and women …
