The scientific conclusion was based on a detailed study of healthy joggers and healthy but sedentary non-joggers for sometime. The study focused on hours of jogging, frequency, and the individual's perception of pace. As it is known, individuals' pace may vary from person to person.
Early studies have found that more than moderate exercise may cause more harm than good.
Peter Schnohr, MD, DMSc, a researcher from, Copenhagen, Denmark concluded that while jogging, pace of joggers is very important as the pace of the slow joggers corresponds to vigorous exercise and strenuous jogging corresponds to very vigorous exercise. However, 'decades of high-level activities could cause health risks, and may affect the efficiency of the cardiovascular system.'
World over people are leading a stressful life and if your target is to decrease the risk of heart problems and improve your life expectancy, jogging a few times a week at a moderate pace is a good bet as too much of anything is harmful. Besides, watch out your dietary habits.
