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

Not Applicable

Completed

• Conditions: Healthy Individuals
• Interventions: Other: exercise; Other: exercise with blood flow restriction

• Registration Number: NCT04206345
• Lead Sponsor: Dokuz Eylul University

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.

Arm && Interventions

Group	Intervention	Description
Exercise Group	exercise	Elbow bending exercises with resistance exercise band (%70 of 1 maximum repetition) will be performed for one session.
Blood Flow Restriction Group	exercise with blood flow restriction	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.

Primary Outcome Measures

Name	Time	Method
Strength	baseline measurements and after 10 minutes of one exercise session	Change of biceps muscle strength(in kg, with hand held dynamometer)

Secondary Outcome Measures

Name	Time	Method
Modified Pull-Up Test	baseline measurements and after 10 minutes of one exercise session	Number of pull-ups will be recorded
Elbow proprioception	baseline measurements and after 10 minutes of one exercise session	change of elbow proprioception for three degrees: 45, 60 and 75 (with digital inclinometer)
Upper Extremity Closed Kinetic Chain Stabilization Test	baseline measurements and after 10 minutes of one exercise session	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.
Functional Throwing Performance Index	baseline measurements and after 10 minutes of one exercise session	Participants will throw a ball to shot a frame on a wall. Number of correct shots will be recorded
Shoulder proprioception	baseline measurements and after 10 minutes of one exercise session	Change of shoulder proprioception for 100 abduction (with bubble inclinometer)
