In a groundbreaking new study published in the Journal of Cancer Research, researchers from Tel Aviv University in Israel have shed light on the potential benefits of aerobic exercise in reducing the risk and recurrence of certain types of cancer. The study, which involved analyzing health data from over 2,700 individuals over a span of 20 years, revealed some intriguing findings.
The researchers discovered that those who engaged in regular high-intensity aerobic workouts, such as running, experienced a staggering 72% reduction in metastatic cancers compared to those who led sedentary lifestyles. To further investigate the mechanisms behind this phenomenon, the researchers conducted a second phase of the study using mice injected with melanoma cancer cells.
The results were equally compelling. Mice that engaged in regular exercise exhibited fewer metastatic tumours than their sedentary counterparts. This led the researchers to hypothesize that aerobic exercise creates a higher demand for glucose in internal organs, effectively “starving” cancer cells of their essential fuel.
James Hicks, a professor of ecology and evolutionary biology at the University of California Irvine, commented on the study’s findings in the Healthline report, stating, “The study provides good evidence that regular aerobic exercise results in reprogramming those metabolic pathways associated with glucose utilization — which they refer to as a ‘metabolic shield.’ This exercise-induced ‘reprogramming’ of healthy tissues increases competition for glucose, thus ‘stealing’ vital energy from cancer cells.”
While running emerged as the most beneficial form of exercise in this study, swimming, cycling, and rowing were also found to be helpful. High-intensity exercise like running may not be suitable for everyone due to factors such as age and physical condition. However, moderate exercise still demonstrated a protective effect against cancer. Numerous epidemiological studies have shown that regular activities like brisk walking can significantly reduce the risks of various types of cancers by 10 to 20%.
In addition to its potential medical benefits, exercise also offers psychological advantages that can enhance outcomes and quality of life for cancer patients. Joy Puleo, the director of education at wellness company Balanced Body and a cancer survivor herself, highlighted in the same report the empowering nature of exercise during the cancer journey. She emphasized that exercise provides patients with a measure of control and an opportunity to engage their support network.
When it comes to choosing an aerobic exercise, Puleo advised finding an activity that one enjoys and can commit to on a regular basis. The key is to challenge oneself and incorporate elements of difficulty into the routine. Whether it’s cycling, walking, or even dancing, any form of aerobic exercise can be effective in supporting overall health and well-being.
While this study provides valuable insights into the links between exercise and cancer progression, further research is needed to optimize the volume and intensity of exercise for a broader population of cancer patients. Nonetheless, the findings underscore the importance of incorporating regular aerobic exercise into one’s lifestyle as a proactive measure against cancer.
As more studies continue to explore the impact of exercise on cancer risk and recurrence, it is becoming increasingly clear that physical activity is not only beneficial for overall health but also holds promise in reducing the burden of cancer. So lace up your running shoes or grab your swim goggles – it’s time to embrace the power of aerobic exercise in the fight against cancer.
