New Delhi, Sep 16: A recent study by Edith Cowan University reveals that both resistance training (RT) and high-intensity interval training (HIIT) generate myokines—muscle-produced proteins with anti-cancer properties—that can help slow breast cancer cell growth.

Resistance training, which involves lifting weights to build muscle and strength, and HIIT, characterized by short bursts of intense exercise followed by brief rest periods, were tested on breast cancer survivors over a 12-week program. Blood samples from participants showed that both exercise types reduced breast cancer cell growth in lab tests by 22% and 25%, respectively.

Francesco Bettariga, one of the researchers, explained that while both exercise methods were effective, HIIT’s impact was notably linked to increased lean muscle and decreased body fat. The study highlights that resistance training primarily boosts muscle mass and strength, whereas HIIT enhances cardiovascular fitness and reduces fat.

“Our findings suggest that regardless of the exercise type, engaging in physical activity raises myokine levels, which may contribute to slowing cancer progression,” said Bettariga. This underscores the importance of exercise in cancer recovery and prevention through different physiological pathways.
