Improving physical fitness can reduce the risk of prostate cancer by 35%: study

London, Feb 4 (IANS) Increasing annual cardiorespiratory fitness by three percent or more could reduce the risk of developing prostate cancer by 35 percent, a new study suggests.

The findings, published in the British Journal of Sports Medicine, led the researchers to conclude that men should be encouraged to improve their level of fitness to help reduce their chances of contracting the disease.

In the study, researchers collected data on physical activity, lifestyle, perceived health, body mass and height measurements, and the results of at least two cardiorespiratory fitness tests, which were they measured in a stationary cycle, for 57,652 men. a total of 181,673.

The men completed at least two fitness tests to determine how much oxygen they used during vigorous exercise; more oxygen equals better fitness.

The findings were compared with those of men who later developed the disease.

Over an average period of nearly 7 years, 592 men (1 percent of the total sample) were diagnosed with prostate cancer, and 46 (0.08 percent) died of their disease, the study found.

“An annual percentage increase in absolute cardiorespiratory fitness was associated with a 2% lower risk of prostate cancer, but not death, after controlling for potentially influential factors such as age, education level, year of testing, weight (BMI) and smoking status,” the researchers said.

“When participants were grouped according to whether their cardiorespiratory fitness had increased, remained stable or fallen, those who had improved by 3% or more per year were 35% less likely to develop prostate cancer than those who had declined. , after taking into account potentially influential factors,” they added.

The researchers emphasized that this is an observational study and as such cannot establish causal factors, adding that genetic factors play an important role in both a person’s cardiorespiratory fitness and cancer risk .
