N/A forearm pump. Intervention 1: Intervention group: In this group, the blood flow restricting cuff will be placed proximally around the dominant arm of the participant for 30 minutes. In this period of time, the cuff is inflated in 3 cycles of 5 minutes of ischemia with a pressure of 220 mm Hg, in order to create a complete blockage in the arterial blood flow. Ischemic cycles are separated by 5 minute intervals of cuff deflation and reperfusion. Intervention 2: Control group: In this group, the blood flow restricting cuff will be placed proximally around the dominant arm of the participant for 30 minutes. In this period of time, the cuff is applied in 3 cycles of 5 minutes with a pressure of 0 mm Hg. These cycles are separated by 5 minute intervals of opening the cuff. Yes - There is a plan to make this available What will be shared: All personal data of participants can be shared after de-identification. In addition, the study protocol, statistical analysis, informed consent form and reports of the study will be shared. When: 6 months after publication by contacting the corresponding author To whom: Researchers working in academic and scientific institutions Conditions: For meta-analysis Biomechanics simulation or any other type of usage with the researchers' discernment Where to obtain: Contact the corresponding author of the article How to obtain: Contact the corresponding author of the article Meeting the requirements of users (being a researcher) Document submission Comments:
