The study was a parallel randomized trial. Thirty-two healthy men between the aged 21 to 23 years old were recruited and randomly assigned to two 16-member groups: a group participating in the WBV intervention (n = 16) and a group without the intervention (placebo: PL, n = 16). Participants drew numbers from 1 to 32: even numbers were placed in the WBV group, odd numbers in the PL group. The men were physically active, but did not engage in competitive sports. Only healthy men with normal BMI and similar physical activity were included in the study. Exclusion criteria were metabolic diseases, overweight or obesity, use of stimulants and pharmaceuticals, and anxiety disorders. Medical qualification for participation in the project was made by a physician.Diet, physical activity, body composition and resting metabolic rate were analyzed in the participants. Body composition analysis and RMR measurement were performed twice, i.e. before and after completion of the WBV series (n = 10). The intervention lasted 2 weeks and WBV was performed 5 times a week (Monday–Friday) in the hours up to noon. All subjects completed the full series of 10 WBV, as well as all scheduled tests were performed in the study. Participation in the study was voluntary, and participants at any stage of the project were allowed to opt out of further participation. All study participants signed a consent form to participate in the project. The project was approved by the Bioethics Committee of Opole Medical School (no. KB/56/NOZ/2019).
