IRCT20210111050007N1 IRCT 2021-05-18 Tehran University of Medical Sciences The effects of resistance training associated with blood-flow restriction on the quadriceps muscles in CORONA virus survivors after recovery BFR The effects of low-load resistance training associated with blood-flow restriction on function, strength and thickness of the quadriceps muscles in COVID-19 survivors after recovery 2021-04-09 anticipated 18 Complete https://irct.ir/trial/54533 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, simple randomization by using sealed envelop will be used to allocate the included participants in experimental and control group, Blinding description: The patient is blind to the allocated group and type of treatment. The main researcher is not blind and apply the experiment ( exercises) on patients. The assessor is blind to the type of treatment of the patients. N/A Muscle weakness. Intervention 1: Intervention group : Using low load exercises with blood flow restriction device using strength training protocol in such a way that 80% of the pressure that causes the pulse to be cut is used . The sports version is in 4 sets with 30 repetitions in the first set and 15 times in the other three sets. Exercises with low load (15-40% of the maximum weight that a person can lift once). The device used is the standard model of the blood flow restriction device, which has vascular Doppler, which has the Smart Tools brand from the United States. Intervention 2: Control group: Exercises with low load using the cuff of the same device with minimal pressure to prevent the effects of placebo. The number of repetitions and sets as well as the amount of exercise load is similar to the intervention group.
