ABSTRACT

The purpose of this study was to investigate the immediate and sustained effects of static stretching (SS), dynamic stretching (DS) with no-load (DSNL), DS with a light load (DSLL, 0.25 kg), and DS with a heavy load (DSHL, 0.5 kg) on the hip joint range of motion (ROM). Sixteen participants (63.2 ± 7.13 years) were randomly assigned to perform SS, DSNL, DSLL, and DSHL exercises. The ROM for passive flexion and extension of the right hip joint was measured at pretest, as well as immediately after and at 60 min after completing the exercise. Additionally, the ROM of hip flexion and extension during the stretching exercise was evaluated by kinematic analysis of video-captured images. Passive ROM measurements reveals that the hip flexion ROM was higher after DSNL than after DSLL and DSHL at both time points (DSNL vs. DSLL, DSHL: 0 min: 7.0% vs. -1.8%, -3.9%; 60 min: 7.8% vs. -2.1%, -1.4%, p < 0.05), as well as higher than after SS at 60 min after exercise (DSNL vs. SS: 7.8% vs. 1.0%, p < 0.05). Compared to SS, all types of DS demonstrated a more sustained effect of ROM improvement at 60 min (DSNL, DSLL, DSHL vs. SS: 8.0%, 5.6%, 7.0% vs. 1.6%, p < 0.05). These results suggest that all DS modes can effectively improve hip extension ROM in the elderly. DSNL may be the most effective exercise for improving hip flexion ROM, providing sustained effect for over 60 min.

Key Points
  • All dynamic stretching (DS) modes can effectively improve hip extension range of motion of older adults in the present study.
  • DS with no load (DSNL) may be the most effective exercise for improving hip flexion range of motion, providing sustained effect for over 60 min.
  • We recommended to replace static stretching with DSNL in health promotion activities within elderly communities, in order to accelerate warm-up time and exert a positive effect on hip range of motion.
