Experimental design. Red ovals denote the blood sampling time points once every 30 min. Before and after the impact loading the participants were in supine position. The impact loading changed on each experimental day. The four modes of impact loading are illustrated beneath the timeline (from left to right): jumping inside the short-arm-centrifuge (AGJ), jumping inside the sledge jump system (SJS), jumping without device (EGJ), and running on a treadmill (RUN).
