Acute Effects of Exercises Combined With Blood Flow Restriction in Healthy Individuals

Study Overview
=================
Brief Summary
-----------------
Purpose of the study is; to investigate the acute effects of exercises combined with blood flow restriction on strength, proprioception and functional motor performance in healthy individuals. The investigators hypothesized that blood flow restriction exercises has a positive effect on strength, proprioception and functional motor performance.

Detailed Description
-----------------
60 healthy individuals will randomized into 3 groups of 20 people each. Participants will be held in a familiarization session before 3-4 days the actual evaluation. Elbow bending exercises with blood flow restriction will be performed to the blood flow restriction (BFR) group, elbow bending exercises without blood flow restriction will be performed to the exercise group and control group will not receive any interventions. Participants will be evaluated before and after the exercise session. Control group is going to rest for 10 minutes before the second evaluation. Evaluation protocol includes; muscle strength measurement with digital hand dynamometer, shoulder and elbow proprioception evaluation with inclinometer, Upper Extremity Closed Kinetic Chain Stabilization Test, Functional Throwing Performance Index and Modified Pull-Up Test.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Blood Flow Restriction Group<br>Elbow bending exercises with resistance exercise band (%20 of 1 maximum repetition) for one session. Blood flow restriction band will be placed during exercise session. The first set of exercises will be 30 repetitions then 3 sets of 15 repetitions. Totally 75 repetitions will be performed. 30 seconds rest interval between sets will be given. | Other: exercise with blood flow restriction<br>* Elbow bending exercises with blood flow restriction will be performed to the exercise group.<br>|
| Experimental: Exercise Group<br>Elbow bending exercises with resistance exercise band (%70 of 1 maximum repetition) will be performed for one session. | Other: exercise<br>* Elbow bending exercises<br>|
| No Intervention: Control Group<br>10 minutes resting period will be given between evaluation. | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Strength | Change of biceps muscle strength(in kg, with hand held dynamometer) | baseline measurements and after 10 minutes of one exercise session | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Shoulder proprioception | Change of shoulder proprioception for 100 abduction (with bubble inclinometer) | baseline measurements and after 10 minutes of one exercise session | 
| Elbow proprioception | change of elbow proprioception for three degrees: 45, 60 and 75 (with digital inclinometer) | baseline measurements and after 10 minutes of one exercise session | 
| Modified Pull-Up Test | Number of pull-ups will be recorded | baseline measurements and after 10 minutes of one exercise session | 
| Upper Extremity Closed Kinetic Chain Stabilization Test | This test will be occurred in plank position. Participant will touch with one hand to other while maintaining the position. Number of touch will be recorded. | baseline measurements and after 10 minutes of one exercise session | 
| Functional Throwing Performance Index | Participants will throw a ball to shot a frame on a wall. Number of correct shots will be recorded | baseline measurements and after 10 minutes of one exercise session |
