WebJan 1, 2024 · The ankle dorsiflexion angle was significantly reduced in the descending phase of jumping. More stability is required when landing, which demands ankle dorsiflexion and knee flexion to absorb the... WebGround reaction forces (GRFs) were measured using 4 piezoelectric sensors placed on the corners of the platforms, so each force value corresponded to the motion data value at 240 Hz. The accurately recorded take-off and landing times allowed us to assess the duration of the flight phase and hence calculate the jump height.
