[Purpose] To determine the relationships of the quadriceps rate of torque development and
the time to peak torque with the physical function of the elderly. [Subjects and Methods]
Twenty-one subjects participated in this study. Quadriceps strength was measured using
isometric and isokinetic torque tests. Time to peak torque and rate of torque development
were calculated from the torque time curve of the isokinetic and isometric torque tests,
respectively. Physical activities were measured using 4 physical activity tests. Pearson
correlation coefficients were used to examine the relationships among the variables.
[Results] The time to peak torque showed significant correlations with all measures of
physical activity tests. Rate of torque development showed significant correlation with
the timed stair-climbing test. Isometric and isokinetic torques had no significant
correlations with any of the physical activity tests. [Conclusion] Time to maximum torque
and the rate of torque development might be more important than peak torque in determining
the physical function of the elderly. |
