RECRUITMENT
This study was supposed to be conducted on military forces, but due to the lack of access to a sufficient number of the relevant participants, the population was changed to active young men. However, no other changes were made in the inclusion and exclusion criteria for selecting the subjects. Therefore, a total of 52 recreationally active men aged 20–35 years were recruited. At the recruitment stage the participants performed ≥2 exercise sessions per week for the past 3 months and were not injured. None of them had any background in regular PJT or competitive sports with any kind of jumping exercises during the trial. During the study, five subjects withdrew due to personal reasons and consequently data from 47 subjects (mean ± standard deviation [SD]: age, 26.5 ± 3.9 years; body mass, 78 ± 9.2 kg; body height, 173.7 ± 7 cm; body mass index [BMI], 25.8 ± 2 kg/m
