Stretching exercises

EXPERIMENTAL

Interventions are home-based stretching exercises. The experimental group will receive 6 stretching exercises which stretch 20-30 seconds, relax for 10 seconds, and repeat 5 times for each side. It will take 25-30 minutes every day for continuous 8 weeks.

Other: stretching exercises

Control group

NO INTERVENTION

Maintain their daily activity level in the 8 weeks. We use the study desigh-''waiting list control'' in this group.

Interventions

stretching exercises OTHER

Our interventions are home-based stretching exercises. The experimental group will receive 6 stretching exercises which stretch 20-30 seconds, relax for 10 seconds, and repeat 5 times for each side. It will take 25-30 minutes every day for continuous 8 weeks. Those include stretching of the deep front line, spiral line, superficial front line, lateral line, superficial back line, and plantar flexors. Designed concepts are the following three: 1) based on ''Anatomy- Train'' theory, 2) emphasize on movements of trunk and pelvis, and 3) stress on the stretching of lower extremities.
