Date and Time: 2020-08-15 18:36:14

Recently,the paper on physical activity and human health was published in the top international medical journal-British Medical Journal (Impact Factor: 30.223) by Prof. Xi Bo from the School of Public Health of Shandong University in cooperation with Dr. Sreenivas P Veeranki from the University of Texas Medical Branch, USA and Dr. Costan G Magnussen from the University of Tasmania, Australia. Dr.Zhao Min is the first author and Shandong University is the first institute.

Previous studies showed that physical inactivityis a major risk factor for chronic non-communicable diseases worldwide. Although physical inactivity has been estimated to be responsible for 9% of premature death and $53.8 billion in health costs, it is still a worldwide public health problem. The 2018 physical activity guidelines for Americans recommend that adults should engage in at least 150 minutes of moderate-intensity aerobic physical activity (e.g. jogging, dancing, etc.) or at least 75 minutes of vigorous-intensity aerobic physical activity (e.g., faster running, playing basketball, etc.) each week, or an equivalent combination of both. Unfortunately, this study showed that, in the general population, only 16.0% engaged in both recommended aerobic and muscle strengthening activities, 24.0% in recommended aerobic activity only, and 4.5% in recommended muscle-strengthening activity only.

Based on data from about 0.48 million adults with 9 years of follow-up, Xi et al. found that compared with participants not meeting the physical activity guidelines, the risk of all-cause mortality was 11% lower in those engaging in recommended muscle-strengthening activity and 29% lower in those engaging in recommended aerobic activity, and 40% lower in those who engaged in both activities. In addition, adults who engaged in recommended physical activity were at reduced risk of mortality from cardiovascular disease, cancer, chronic lower respiratory tract diseases, influenza and pneumonia, nephritis, and Alzheimer's disease, etc. The study also indicated that the beneficial effects on mortality risk are largely comparable between two intensities of aerobic activity each week (≥150 minutes of light to moderate intensity versus ≥75 minutes of vigorous-intensity). People can choose the appropriate type of physical activity according to their physical condition.

The study was supported by the Innovation Team of the "Climbing" Program of Shandong University, Youth Team of Humanistic and Social Science of Shandong University, and a National Heart Foundation of Australia's future leader fellowship.
