Recent research from Edith Cowan University (ECU) suggests that a single session of resistance training or high-intensity interval training (HIIT) may contribute positively to cancer management. The study, conducted by PhD student Francesco Bettariga, found that such exercise can elevate levels of myokines—proteins produced by muscles that may have anti-cancer properties—by 20 to 30 percent, potentially inhibiting cancer cell proliferation.
Bettariga's study specifically focused on breast cancer survivors, measuring myokine levels before, immediately after, and 30 minutes following exercise. The results indicated that both forms of physical activity effectively increased myokine levels, a finding that aligns with existing evidence supporting exercise as a safe and beneficial adjunct to cancer treatment.
The implications of these findings suggest that integrating exercise into standard cancer care could be advantageous. Bettariga emphasized the need for further investigation into the long-term benefits of elevated myokine levels, particularly concerning cancer recurrence.
Additionally, Bettariga's research explored the relationship between body composition and inflammation, which plays a significant role in breast cancer outcomes. Chronic inflammation can exacerbate tumor progression and impair immune function, placing cancer survivors at a heightened risk of recurrence and mortality. The study indicated that consistent exercise could improve body composition by reducing fat mass and increasing lean mass, thereby potentially lowering inflammation levels.
Bettariga cautioned against quick weight-loss methods that do not incorporate exercise, as these may not effectively build or preserve muscle mass, which is necessary for producing beneficial myokines. Overall, the research highlights the potential role of exercise in supporting cancer recovery and suggests that comprehensive strategies to manage inflammation could enhance survival outcomes for breast cancer survivors.
