The purpose of this study was to describe the contributions of individual leg muscles to the production of ground reaction forces (GRF) during basketball related tasks. One male and female college basketball player performed horizontal drop vertical jumps (DJ) and lateral side steps (SS). Motion capture and GRF data were recorded and used as inputs to an induced acceleration analysis to calculate the contribution of each muscle to the GRF during each task. Soleus and vasti muscle forces were the respective primary and secondary contributors to vertical GRF during the DJ. Forces from the vasti muscle group were also the primary contributor to posterior braking GRF during the DJ. Medial GRF during the SS were primarily the result of vasti and soleus muscle forces. Muscle force contributions to GRF did not differ markedly between players.
