Effects of superficial heat and active exercise warm-up on active knee range of motion.

摘要

This study evaluated the effectiveness of hot packs and active exercise warm-up prior to static stretching on active knee range of motion (ROM). Fifty-four adult subjects recruited from a convenience sample were randomly assigned into four groups: control, static stretching, hot packs and stretching, or brisk treadmill walking and stretching. The active knee extension test (AKET) assessed pretest and posttest measurements. It was hypothesized there would be statistically significant differences in active knee ROM as measured by AKET between treatment groups and control. ANOVA and Tukey post hoc analysis revealed statistically significant differences between treatment groups and control (p = .0002). No significant differences existed between individual treatment groups although treadmill walking yielded greatest pretest posttest changes (8.71°).
