Twenty-eight healthy male university students with a mean age of 32.12 (SD 2.45) years from King Saud University, Riyadh, were recruited via opportunity sampling. The minimum, maximum, and median ages of the participants were 27, 35, and 32.5 years, respectively. A self-reported screening survey was adapted to exclude participants with a pre-existing orthopedic surgery, nervous system disorder, articular pain, a history of musculoskeletal disorder, injury to the arms, legs, or spine, or a heart and/or lung problem, an allergic reaction to any adhesive and gel materials used in this study, or sleep disturbance in the two weeks prior to the experiment. Moreover, each participant was also asked to avoid eating two hours before training or data collection. Participants were also instructed to have a normal amount of sleep (approximately six hours of sleep each night) and refrain from engaging in any excessive physical activity before the experimental sessions. Participants in the experiment were selected so that they had little to no background information about the task to be performed.The IRB’s approval for this experiment was obtained from the Human Participants Review Sub-committee, the Institutional Review Board, King Khalid University Hospital, the College of Medicine, and King Saud University. The approved written informed consent form (ethical approval code: E-19-4467) was readied and signed by each participant before participating in the experiment.
