Cardiorespiratory fitness is a person’s ability to do aerobic exercise, such as running, cycling, and swimming for prolonged periods, or even to climb stairs without getting too out of breath. If we already know that this “cardiorespiratory form” is associated with a lower risk of developing certain cancers, few studies have looked into this long-term association.
It is therefore to overcome this lack that a Swedish team studied the data of registers covering general information, medical diagnoses and deaths of conscripts who did their military service between 1968 and 2005.
At the start of their service, when they were between the ages of 16 and 25, the participants underwent a battery of tests ranging from measuring their height, body mass index, blood pressure, muscle strength and their cardiorespiratory fitness.
Thus, for more than 340,000 conscripts, the level of cardiorespiratory fitness was considered high, for 519,000 it was moderate, and for 365,800 it was low. Interestingly, the less fit had a higher propensity for obesity or alcohol abuse.
Increase cardiorespiratory fitness in young people
Over the thirty years that this work lasted, 7% of the participants developed cancer. And, compared to men with a low level of physical fitness, those with good cardiorespiratory capacities had a lower risk of developing colorectal cancer (-5%), pancreatic cancer (-12%), cancer of the intestine (-18%), head and neck (-19%), kidney (-20%), stomach (-21%), esophagus (-39%), liver ( -40%) and lung (-42%).
On the other hand, surprisingly, better physical condition was associated with an increased risk of skin cancer. Sun exposure during sports might explain these results, the researchers suggest. Before concluding: “This study shows that higher physical fitness in young men is associated with a lower risk of developing nine types of cancer. These results might be used in the development of public health policies aimed at increasing cardiorespiratory fitness in young people. »
