Running Distance and Biomechanical Risk Factors for Plantar Fasciitis: A 1-yr Prospective 4HAIE Cohort Study.

Here, the data indicate that an optimal running dose of less than 48 km·wk −1 is more appropriate for health due to an observed trend of a reversed J-shape curve in all-cause death and coronary heart disease data (i.e., more than 48 km·wk −1 progressively attenuated the health benefits and became detrimental for cardiovascular health) ( 46 ).
