fatigue, Fatigue
The participants were asked to complete the following four self-administered questionnaires: visual analog scale, Brief Fatigue Inventory (BFI), POMS2 (Kanekoshobo, Tokyo, Japan), and BDI-II (Nihon Bunka Kagakusha, Tokyo, Japan). The participants were asked to complete all questionnaires on the day of the laboratory measurements. Participants completed the questionnaire following an overnight fast of more than 12 h, as with the other measurements. The participants completed the questionnaires at their own pace, and there was no time limit. Questionnaires were administered in the same manner before and after the intervention. Using the visual analog scale, participants were asked to indicate the intensity of perceived fatigue on a 100-mm horizontal line. The left side stated, “having no fatigue”, whereas the right side stated, “having maximum fatigue”
