A new study has found, men with high levels of cardiorespiratory fitness have low prevalence of lung or colon cancer.
13,949 middle-aged men were examined for cardiorespiratory fitness (CRF) between 1971 and 2009 by researchers from the University of Vermont. Each participant’s CRF was assessed by means of incremental treadmill test starting at 3.3 mph for 25 minutes, before an increment of 0.3 mph per minute until exhaustion of their own volition.
In the present report, three types of cancer, prostate, colorectal and lung were evaluated.
Those with high levels of CRF had a lower risk of developing lung or colon cancer as compared to men with lower levels of CRF. And if they did have high levels of CRF, they were less likely to die of cancer, researchers found.
Dr. Dale Shepard, an oncologist at Cleveland Clinic who did not take part in the study said, “This is important because more and more data is coming out that regular exercise is important to prevent cancer.”
The importance of good heart health and consumption of a heart-healthy diet, getting regular exercise, and maintaining a normal weight to decrease cancer risk, was emphasized by Shepard because a sedentary lifestyle increases the risk of cancer.
“What that means is if you have a job where you sit all day long, even if you exercise for an hour or so afterward, you still have risk,” Shepard said. “So really, you have to think about both things – being active but not being inactive.”
