Men who regularly practice heart-pounding exercises are less likely to develop Cancer, reveals a new study published in the British Journal of Sports Medicine.
The main reason behind this was the higher rate of oxygen consumption among people who exercised.
Researchers in the Universities of Oulu and Kuopio in Finland studied the leisure-time physical activity, over a one-year period on 2560 men in the age group 42 and 61, with no history of cancer.
Following a period of 16 years, 181 of the subjects died from cancer, mainly pertaining to stomach, intestine, lungs, brain and prostate.
The scientists measured the metabolic units of oxygen consumption using an intensity scale or exercise, and found that men who exercised for a minimum of 30 minutes a day, were half as likely to get cancer, when compared to those who did not.
Maximum reduction was found in gastrointestinal and lung cancers, and was true even when other factors such as alcohol consumption, age, weight, smoking, were all taken into account.
The researchers concluded that the intensity of leisure-time and physical activity should be moderate, so that, beneficial effects for reducing overall cancer mortality can be achieved.
Longer and more intense physical activity can also help in maintaining cognitive skills among people as they age, the researchers pointed out.
