Men with better cardio fitness had a lower risk of certain cancers, according to a new study conducted by researchers from The Swedish School of Sport and Health Sciences. The study, published in JAMA Network Open, analyzed data from 177,709 Swedish men aged 18 to 75 over a period of nearly 10 years.
The researchers aimed to determine the relationship between cardio-respiratory fitness and the risk of developing or dying from lung, prostate, and colon cancers – three of the most common cancers in men. To measure cardio fitness, they used VO2 max, which measures the body’s ability to use oxygen during exercise. Men pedaled on a stationary bicycle for six minutes, with the aim of achieving a steady heart rate, which was then used to calculate VO2 max.
Based on their cardio fitness levels, the participants were divided into four groups. The findings showed that men with the highest levels of fitness had a significantly lower risk of dying from lung, colon, or prostate cancer. Additionally, individuals with higher VO2 max had a lower risk of developing lung or colon cancer, although they had a slightly higher risk of developing prostate cancer.
Even after adjusting for factors like diet, other health conditions, and smoking habits, the results still indicated that participants with at least moderate cardio fitness had a significantly lower risk of colon and prostate cancer death compared to those with the lowest fitness scores. This suggests that cardiovascular health is not only essential for preventing heart diseases but also for warding off certain cancers.
The researchers concluded that increasing physical activity, especially at higher intensities, could be beneficial in preventing deadly illnesses such as certain cancers and heart diseases. They recommended cardio exercises like walking, running, swimming, cycling, and other activities that elevate heart rate and cause increased breathing. These exercises can improve cardio-respiratory health over time, reducing the risk of illnesses and boosting overall mood.
Public health authorities, such as the US Department of Health and Human Services, typically recommend at least 150 minutes of moderate activity or 75 minutes of intense activity per week. However, research indicates that even small doses of regular cardio can improve VO2 max. Low-intensity habits like walking can add up to significant health benefits, while high-energy workouts can yield results in less time.
In conclusion, the study emphasizes the importance of cardio fitness in reducing the risk of common cancers in men. Engaging in regular cardio exercises, even for a few minutes each day, can have a significant impact on overall health and well-being.
