Answer:
Cardiovascular studies
Step-by-step explanation:
Cardiologists and cardiovascular researchers are the scientists that are more often studying the correlation between physical activity and health. According to several studies, physical activity and fitness are highly protective and beneficial against cardiovascular diseases.
Scientists indicate that a moderate fit lifestyle provides health benefits that lead to the reduction of the risk in cardiovascular issues, such as blood pressure and diabetes.
Therefore, cardiovascular studies indicate a reduction in mortality when people abandon a sedentary lifestyle and become moderately fit.
