A research team led by Professor Satoshi Fujita of Ritsumeikan University's College of Sports and Health Sciences, in collaboration with POLA CHEMICAL INDUSTRIES, LTD., investigated the effects of aerobic exercise and strength training on the skin.As a result, it became clear that both improved skin aging.Exercise is known to have an anti-aging effect on the aging of the brain and muscles, but there are no previous studies worldwide on what kind of effect it has on the skin, and the mechanism has not been clarified. I didn't.
In this study, 40 women in their 50s and 61s were subjected to exercise intervention for 4 months, and skin changes were analyzed.The aerobic exercise group and the muscle training group exercised twice a week, and skin measurements, blood sampling, body composition measurements, and exercise performance evaluations were performed before and after the test.
As a result, both aerobic exercise and strength training were found to improve skin elasticity and dermal structure, which are indicators of skin aging.In particular, it was clarified that strength training increases the thickness of the dermis, which thins with age, and reported for the first time in the world that it may contribute to youthful appearance.
As a mechanism for this, we found that changes in blood components due to exercise increase the extracellular matrix (ECM; Extracellular Matrix, which refers to collagen, hyaluronic acid, proteoglycan, etc.) of the dermis, which is an important layer of the skin.In addition, it was found that muscle training reduces inflammatory chemokines (CCL28 and CXCL4) in the blood and increases biglycan, a kind of ECM in the dermis, which leads to an improvement in the thickness of the dermis.
The results of this research clarified the mechanism by which exercise improves skin aging, and can be said to have scientifically demonstrated that exercise has a positive effect not only on health but also on beautiful skin.It is expected to be useful as an opportunity to start exercising and as a motivation to continue exercising.
