Cupping therapy has re-emerged as a potential approach to boost post-exercise metabolic recovery, reduce pain, and improve range of motion by increasing local microcirculation. But what does science tell us aboutRead
Men who perform resistance training 3 times a week for at least 6 months tend to have lower T-helper cell counts than non–resistance trained men. In addition, the natural killer (NK) cell count, an index of innate immunity, has been shown to decrease below the resting value after submaximal resistance exercise in both resistance-trained and non–resistance-trained men. It is a common hypothesis that resistance training impairs the immune system rather than enhancing its functions. This study examined the affects of cystine and theanine on NK cells, inflammation and immunity.

It is the first time researchers have been able to confirm that iron supplementation has beneficial effects on exercise performance. Dr Sant-Rayn Pasricha from the Melbourne School of Population and Global Health said the findings could have implications for improved performance in athletes and health and general health and well-being in the rest of the population. “It may be worthwhile screening women, including women training as elite athletes, for iron deficiency, and ensuring they receive appropriate prevention and treatment strategies. Athletes, especially females, are at increased risk of iron deficiency potentially, due to their diets and inflammation caused by excessive exercise,” said Pasricha.
