Just Two Weeks of Physical Inactivity May Increase the Risk of Chronic Diseases
A team of researchers from the University of Liverpool in the United Kingdom found that switching from physically active regimen to physical inactivity for only 14 days led to metabolic changes in young healthy adults raising the risk of chronic diseases, such as type 2 diabetes, and heart disease, as well as the risk of premature death.
For their study, the researchers enrolled 28 young healthy adults with an average age of 25. Their mean BMI was 25, and they were physically active. During 14 days, they significantly reduce their physical activity and underwent extensive health checks before and after the study.
The scientists found that reducing physical activity for just 14 days led to a loss of skeletal muscle mass in the participants by an average of 0.36 kilograms and an increase of body fat. Additionally, they noticed a reduction in cardiorespiratory fitness and the function of mitochondria, which are the cells' powerhouses.
