Description
Regine Zhou, Lachlan James, and Danny Lum compare in a 2025 study how landing style shapes jump forces in assisted and plain jumps. Past work split on whether assisted jumps raise landing impact, likely due to varied landing habits. Impact size matters because it steers how muscles adapt to training.
Thirteen trained athletes, five women and eight men, jumped on a force plate in the lab. Each did plain and band assisted jumps at 60% to 90% of body weight. Landings were cued soft or stiff, three jumps per setting for each athlete. Jump height rose and push off time shrank as aid increased in both styles. Push forces fell with more aid, while landing impact grew with more assistance.
