RELATIONSHIPS BETWEEN TRUNK AND KNEE ACCELERATION AND THE GROUND REACTION FORCE DURING SINGLE LIMB LANDING

Abstract

The purpose of this study was to investigate the relationship between the ground reaction force and acceleration of the knee and trunk. We measured trunk and knee acceleration, as well as ground reaction force during single limb landing in 7 female basketball players. The associations between trunk and knee accelerations and vertical ground reaction force were analyzed by using correlation coefficients. Strong correlations were found between peak vertical ground reaction force and peak acceleration of the medial, vertical, and posterior trunk, trunk resultant, vertical knee, as well as knee resultant. It is possible to evaluate the variable movements during sports or sports-related activity by analyzing the acceleration of body segments.
