New research published today in The Journal of Physiology shows that 12 weeks of easy-to-administer passive stretching helps improve blood flow by making it easier for your arteries to dilate and decreasing their stiffness. 

Passive stretching differs from active stretching in that the former involves an external force (another person or gravity) stretching you, whereas active stretching is performed on your own. The changes they observed in blood vessels could have implications for diseases, including the number one global killer, heart disease. 

It has been demonstrated that the benefits of assisted stretching can help relieve sore muscles and stiff joints by enhancing circulation. That’s not all, though. More advantages of assisted stretching should be considered, especially if you’re an athlete or have chronic pain problems. Check Castleflexx for more about this.

Researchers at the University of Milan assigned 39 healthy participants of both sexes to two groups. The control group didn’t undergo any stretching. The experimental group performed leg stretches five times a week for 12 weeks.

Researchers evaluated the effect of passive stretching on the blood flow locally and in the upper arm. They found that the arteries in both the lower leg and upper arm had increased blood flow and dilation when stimulated, along with decreased stiffness. 

Both of these changes may have implications for diseases such as heart disease, stroke, and diabetes as they are characterised by changes in blood flow control, due to an impaired vascular system. 

If this study is replicated in patients with vascular disease, it could indicate whether or not this training method could serve as a new drug-free treatment for improving vascular health and reducing disease risk, especially in people with lower mobility.  

Moreover, stretching may also be used during hospitalisation or after surgical interventions, in order to preserve vascular health when patients have low mobility. It can be also performed at home by carers or family members.  

Emiliano Ce, an author of the paper, said: “This new application of stretching is especially relevant in the current pandemic period of increased confinement to our homes, where the possibility of performing beneficial training to improve and prevent heart disease, stroke, and other conditions is limited.”
