The purpose of this single case study is to provide an overview on knee joint loading in counter movement jumps using different landing strategies and additional loads. One athlete experienced in jump training performed counter movement jumps and jump landings with additional barbell loads of 0 kg, 20 kg, 40 kg, 60 kg, 80 kg and with variations in landing conditions: "regular","soft", "elevated" and "spotted". GRF and kinematics were measured, and peak forces, peak knee moments and peak knee powers were determined using inverse dynamics. Different loading conditions and landing conditions lead - as expected - to different knee joint loadings and can therefore be used to specifically control the amount of loading during jump or jump strength training. The most effective in terms of high training loads and low landing joint loading are elevated and spotted landing conditions.
