IMPULSE AND AVERAGE GROUND REACTION FORCES IN STEP EXERCISE
Keywords: ground reaction forces, impulse, step
AbstractThe purposes of this study were to analyse selected components of ground reaction forces (GRF) during Step Exercise and to investigate the differences that exist between four stepping rate conditions (125, 130, 135 and 140 beats per minute - bpm) and between four Step patterns (basic step, knee lift, run step and knee hop), performed with right and left leading foot in terms of net average GRF, net impulse, and total time of contact, in a group of 18 experienced females. These parameters were explored concerning ascending and descending phases of the movements. The present investigation provides normative data of biomechanical parameters on the external forces of Step movements.
