In a study published in the British Journal of Sports Medicine, the researchers say that 11 minutes a day (75 minutes a week) of moderate-intensity(强度) physical activity—such as fast walking—would be sufficient to lower the risk of diseases such as heart disease, stroke and a number of cancers.
To explore the amount of physical activity necessary to have a beneficial impact on several chronic(慢性的) diseases and early death, researchers carried out a systematic review, collecting and analysing data from all of the published evidence. In total, they looked at results reported in 196 peer-reviewed articles, covering more than 30 million participants from 94 large study teams, to produce the largest analysis to date of the association between physical activity levels and risk of heart disease, cancer, and early death.
The researchers calculated that if everyone in the studies had done at least 150 min per week of moderate-intensity activity, around one in six (16%) early deaths would be prevented. One in nine (11%) cases of cardiovascular(心血管的) disease and one in twenty (5%) cases of cancer would be prevented.
However, even if everyone managed at least 75 min per week of moderate-intensity physical activity, around one in ten (10%) early deaths would be prevented. One in twenty (5%) cases of cardiovascular disease and nearly one in thirty (3%) cases of cancer would be prevented.
Dr Soren Brage from the MRC Epidemiology Unit said: “If you are someone who finds the idea of 150 minutes of moderate-intensity physical activity a week a bit daunting, then our findings should be good news. Doing some physical activity is better than doing none. This is also a good starting position—if you find that 75 minutes a week is manageable, then you could try stepping it up gradually to the full recommended amount.”
