The effect of hip joint exercise using an elastic band on dynamic balance, agility and flexibility in healthy subjects: a randomized controlled trial

Abstract

Objective: The purpose of this study was to examine the effects of hip joint exercise using an elastic band on dynamic balance, agility, and flexibility in healthy subjects. Design: Randomized controlled trial. Methods: Thirty-five subjects (between 19 and 23 years) were randomly allocated to two groups: hip flexion exercise (HFE) group (n=17) and the hip abduction exercise (HAE) group (n=18). The HFE group participated in flexion exercise of the hip joint using an elastic band for 50 minutes a day, three days a week for four weeks, while the HAE group participated in abduction exercises of the hip joint using an elastic band for the same period. Dynamic balance was measured using the timed up and go (TUG) test, agility was measured with the standing long jump, and flexibility was measured using the Schober's test (5 cm, 10 cm). Results: The HFE group showed significant differences in the TUG test, standing long jump, and the Schober's test (10 cm) after training (p<0.05). The HAE group showed significant differences in the TUG test, standing long jump and the Schober's test (5 cm, 10 cm) after training (p<0.05). However, there was no significant difference between the HFE group and the HAE group. Conclusions: Flexion and abduction exercises of the hip joint using and elastic band increased dynamic balance, agility, and flexibility in healthy subjects. Additional research on hip joint exercises using an elastic band for improving dynamic balance, agility and flexibility are necessary.

Investigation of wearing methods of a baby carrier on muscle activation during trunk flexion-extension in healthy women

“…Therefore, it was found that it is necessary to move the load to the leg muscles by lowering the wearing height in order to reduce fatigue and pain of the ES muscles when wearing the baby carrier anteriorly. In addition, the ES muscles appear to require greater muscle activity during the trunk extension compared to flexion, and it seems necessary to distribute the load to be applied to the passive structures of the vertebral muscles and lower back through the adjusted leg movement during the trunk flexion and extension [27].…”
