"Data were collected as part of a longitudinal controlled add-on sports intervention study, in which participants received a 6-weeks sports therapy in addition to their treatment as usual. The main study was registered in the German Clinical Trials Register (DRKS- ID: DRKS00011772) and a study protocol has been published (Oberste et al. ). The experimental group conducted a whole-body vibrations training by performing static and dynamic exercises (e.g., squats, lunges) on the Galileo® Whole Body Vibration Plate Med M (Novotec Medical GmbH, Pforzheim, Germany). The control group executed a myofascial training without muscular or cardiovascular strain, to control for psychosocial attention, by performing seven standardized exercises (e.g., self-massage of legs, arms and back) using a foam roll (Blackroll, Bottighofen, Switzerland). Please refer to the published study protocol for more information about all assessed parameters and details of the sport intervention (Oberste et al. )."
