This study examines the relationship between circulation and walking speed after performing 8-week stretching exercises.
This study examines the relationship between circulations and walking speeds. Most studies in the field of stretching exercises have only focused on improvements of endothelial functions in younger population; however, I aim to emphasize its effects on different populations, such as people with frailty, low physical activity level, weakness and postoperative status. Previous research has established that stretching exercises can improve walking function by modulations of musculoskeletal or neuromuscular system. The importance and originality of this study are that it explores the relationship between circulation and walking speed. Due to the inability to extrapolate outcomes; short-term effect of improved blood vessel function; the unclear mechanism of stretching exercises; and considering the different physical fitness groups, I design a home-based, low-dose, and anatomic chain-based stretching exercises to verify the possible mechanism and effects.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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. |
|
| Control group | No Intervention | Maintain their daily activity level in the 8 weeks. We use the study desigh-''waiting list control'' in this group. |

| 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. |
