One of the better answers to injury prevention in running is to run with less impact. Multiple studies during the past decade has proven heel strike running results in a much higher exposure to a long list of impact force variables as compared with forefoot running. These impact force variables measured in heel strike running include greater peak shear, compressive and ground reaction forces, greater torsional, tensile and rotational stress and a longer brake force duration which produces an excessive jerk, or jolt force. In consequence, the net effect is stark increases in loading on the knees, hips and lower back which will quickly make you injury-prone. Read more here!
