Exercise Could Be a Game-Changer in Battling Breast Cancer
Imagine turning your workout into a weapon against cancer. A new study from Edith Cowan University (ECU) reveals that both resistance training and high-intensity interval training (HIIT) boost myokines—special proteins your muscles release during exercise that fight cancer cells. This exciting find shows how regular workouts might slow breast cancer growth, offering hope especially for survivors.
Resistance training, or RT, involves lifting weights or using resistance bands to build stronger muscles and boost overall strength. On the other hand, HIIT packs intense bursts of activity, like sprinting or cycling hard for short periods, followed by quick rests to ramp up your heart health and stamina. Both approaches pack a punch against cancer, according to researchers.
In the study, breast cancer survivors joined a 12-week program. They either did resistance training or HIIT, and scientists tested their blood samples on breast cancer cells in a lab. The results? RT cut cancer cell growth by 22%, while HIIT reduced it by 25%. "This means both exercises could help slow down cancer cell growth," says Francesco Bettariga, a key researcher from ECU.
What makes HIIT stand out? After 12 weeks, participants saw more lean muscle and less body fat, which directly tied to better cancer-fighting effects. RT shone in building muscle power, while HIIT improved cardio fitness and trimmed fat. "Different exercises hit the body in unique ways," Bettariga explains. "We need to dig deeper into how they trigger myokines and their anti-cancer benefits."
The best part? Everyone in the study ended up with higher myokine levels after the program, no matter which workout they chose. "Whether you pick weights or intense intervals, you’ll likely see benefits for cancer prevention," Bettariga adds.
This research highlights why exercise for cancer survivors matters so much. If you’re looking to incorporate resistance training or HIIT into your routine, talk to a doctor first—especially post-treatment. Studies like this remind us that staying active isn’t just good for fitness; it could be a powerful ally in the fight against breast cancer.
