The Effects of Stretching You Didn’t Know About

With all the benefits stretching provides it’s surprising that limbering up has only recently become the subject of scientific research.

Many studies that have been done show performing a static stretch (stretching a muscle or muscle group as far as it can go and holding the position for longer than 60 seconds) without warm-up exercises can increase muscle strength and the targeted joint’s range of motion. 1)2)3)4)

Not much attention has been given to the additional effects of static stretching. More than likely, the subject hasn’t been widely researched because it seems it won’t yield meaningful results.  

However, a 2021 study titled “Non-local acute stretching effects on strength performance in healthy young adults” (Behm, D. G., Alizadeh, S., Drury, B., Granacher, U., & Moran, J.) was carried out to find out how static stretching affects the opposite side of the body and areas that weren’t stretched.

The study revealed that static stretching affects the stretched muscles and the muscles and joints on the opposite side of the body. The study’s conclusion is consistent with studies that found static stretching increased mobility beyond the stretched body parts. 5)6)7)8)9)

Shining a Brighter Light on the Side Effects of Static Stretching

The discoveries the authors of the previously mentioned study made during a literature review prove that researching the side effects of static stretching may be worthwhile.

The authors reviewed studies that were mainly focused on how stretching affected the performance of the musculoskeletal system. These studies aimed to find out what conditions would maximise physical performance. Most of the participants were healthy young adults. 

One of the team’s discoveries is of interest to athletes and those who play competitive sports: 

After static stretching, the targeted muscle’s performance, strength, and endurance decreased slightly, but the change made a difference. 

(Athletes who want to achieve peak performance during competition and those who play competitive sports may want to avoid static stretching beforehand.)

The Reach of Static Stretching

The research team made another discovery: prolonged static stretching positively affects the stretched body parts’ range of motion and mobility 10)11)12)13) and areas of the body not directly targeted by the stretch.14)

The researchers assume that this is partly because of the myofascial system.

The myofascial system is made up of muscles and connective tissue. 15) The connective tissue is called fascia; it runs throughout the body, enclosing our muscles, organs, bones, and blood vessels. Fascia passes through the muscles and bones and guides nerves, transmitting movement from the muscles to the bones. 16)

Because the fascia is an interconnected network running from head to toe, one body part can transmit movement to another, even if it’s far away. A study showed that head and neck mobility improved after the hamstrings 17) or calf muscles 18) were stretched.

How Static Stretching Can Benefit People Suffering from Musculoskeletal Disorders

Static stretching could be used to help the healing process of immobilised joints. If a cast, splint, or brace has been applied to a body part, joint mobility decreases. The study results show that stretching the opposite body part increases the immobilised joints’ range of motion. 

The results of another study showed that stretching hip flexor muscles on one side of the body increased the range of motion by 6.3%. The range of motion of the hip flexors that were not stretched increased by 5.7% 19) — almost as much as the stretched flexors. 

Static stretching could also be beneficial for people who have musculoskeletal disorders, which include (but are not limited to):

  • Osteoarthritis
  • Rheumatoid arthritis
  • Back or neck pain
  • Tendonitis
  • Carpal tunnel syndrome
  • Degenerative disc disease

Insights for Athletes. Support for Musculoskeletal Disorders. A New Frontier for Research?

The authors of this study made surprising discoveries about the effects of static stretching, which are beneficial for both athletes and people rehabilitating musculoskeletal disorders.  

Their findings show that more research into how static stretching affects areas of the body that aren’t targeted by the stretch is worthwhile.

Further research could improve athletic training and rehabilitation programs for those who have musculoskeletal disorders.
