Men who regularly do heart-pounding exercise are less likely to develop cancer, according to research published this week.

The study, featured in the British Journal of Sports Medicine, found that the key factor in the reduced risk of cancer was a higher rate of oxygen consumption.

Over a 12-month period a team of researchers from the universities of Kuopio and Oulu in Finland studied the physical activity of 2,560 men between 42 and 61- years-old with no history of cancer.

Over an average follow-up period of 16 years, 181 of the subjects died from cancer, mostly of the stomach or intestines, lungs, prostate or brain.

Using an intensity scale for physical exercise that measured 'metabolic units' of oxygen consumption, the scientists found that the men who exercised for at least 30 minutes a day were half as likely to get cancer as those who did not.

"The intensity of physical activity should be at least moderate to reduce the chances of cancer," the researchers concluded.
