Abstract

Cluster Phase analysis was used to examine age-related changes in synchrony between three joints of the lower limb during running stance. Ten male, endurance athletes (Age = 53.54±2.56 years [M50]) participated in the study at baseline (0 years) and then returned for re-testing after seven years (Age = 60.49±2.56 years [M57]). Lower limb coordinate and ground reaction forces were collected as participants performed running trials at a velocity of 3.83±0.40 m/s contacting the force plate with their preferred limb. Statistical parametric mapping identified that the hip, knee and ankle joint synchrony during the stance phase did not change. However tri-joint synchrony was significantly higher at M57 compared to M50 during the absorption sub-phase of stance. The increased joint synchrony as a function of age could be a mechanism associated with this key injury provoking phase.
