Effects of Exercises Combined With Blood Flow Restriction in Healthy Individuals

Effects of Exercises Combined With Blood Flow Restriction on Strength, Joint Position Sense and Functional Motor Performance in Healthy Individuals

Purpose of the study is; to investigate the effect of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. There is no randomized controlled study of the effect of upper extremity exercises performed by restricting blood flow on the joint sensation of individuals and functional motor performance in healthy individuals. For this reason, purpose of the study is; to investigate the effect of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. Pain intensity with the numerical pain rating scale (NRS), muscle strength with digital hand dynamometer, shoulder and elbow proprioception with inclinometer, functional motor performance with Upper Extremity Closed Kinetic Chain Stabilization Test, Functional Throwing Performance Index, Single Arm Shot Put Test, Modified Pull-Up Test evaluation of 60 healthy individuals without neck and upper extremity pain, the fracture and surgical history for the upper extremity, cervical and thoracic area that prevent them to participate in the study will be made. Participants will randomly be separated into 2 groups of 30 people each. Elbow bending exercises with blood flow restriction will be performed to the exercise group during 6 weeks for 3 times a week accompanied by a physiotherapist. Control group will continue daily activities and a brochure on strengthening exercises and protection from injuries. Evaluations will be repeated 2 times and analyzed before the treatment and at the end of the 6th week. With the project, the investigators aim to improve the strength, improve proprioception and functional motor performance in healthy individuals by performing exercises restricting blood flow. With the achievement of the targets, exercises combined with blood flow restriction can be considered among the treatments protective for injuries, healing proprioception. The investigators also believe that the project will blaze the trail for the studies to be performed on athletes.

Detailed Description

Purpose of the study is; to investigate the effect of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. In recent years, the prevalent blood flow restricting exercises seem to favor the development of skeletal muscles in different populations. Studies show that muscular hypertrophy can be achieved also with low-intensity resistance exercises by restricting blood flow. Moreover, exercises combined with blood flow restriction with low mechanical stress and minimal muscle damage do not require a long regeneration process. In this regard, it is stated that the blood flow restricting exercises have lower risk of injuries than the high intensity resistant exercises. It has been shown that similar positive results can be obtained with low-intensity resistance exercises performed by restricting blood flow with classical strengthening exercises performed without limiting in the muscle cross section area. In addition to strength, proprioception and neuromuscular control is important in individuals' therapeutic benefit rates, skills and functionalities, in returning to sports after sports injuries. The investigators believe that classical strengthening exercises may be a contribution to proprioception and consequently to functional motor performance because of the contribution to the proprioception, the low intensity resistant exercise technique performed by restricting blood flow, as well as providing similar muscle growth muscle growth, being painless and harmless to the musculoskeletal system. In this regard, there is no randomized controlled study of the effect of upper extremity exercises performed by restricting blood flow on the joint sensation of individuals and functional motor performance in healthy individuals. For this reason, purpose of the study is; to investigate the effect of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. Pain intensity with the numerical pain rating scale (NRS), muscle strength with digital hand dynamometer, shoulder and elbow proprioception with inclinometer, functional motor performance with Upper Extremity Closed Kinetic Chain Stabilization Test, Functional Throwing Performance Index, Single Arm Shot Put Test, Modified Pull-Up Test evaluation of 60 healthy individuals without neck and upper extremity pain, the fracture and surgical history for the upper extremity, cervical and thoracic area that prevent them to participate in the study will be made. Participants will randomly be separated into 2 groups of 30 people each. Elbow bending exercises with blood flow restriction will be performed to the exercise group during 6 weeks for 3 times a week accompanied by a physiotherapist. Control group will continue daily activities and a brochure on strengthening exercises and protection from injuries. Evaluations will be repeated 2 times and analyzed before the treatment and at the end of the 6th week. With the project, the investigators aim to improve the strength, proprioception and functional motor performance in healthy individuals by performing exercises restricting blood flow. With the achievement of the targets, exercises combined with blood flow restriction can be considered among the treatments protective for injuries, healing proprioception.
