The Effect of Quadriceps Muscle Fatigue on Balance

This study; will be conducted to investigate the effect of quadriceps muscle fatigue on static and dynamic balance in regular physical activity individuals and sedentary individuals. International Physical Activity Questionnaire Short Form (IPAQ), Mini BESTest, Modified Borg Scale questionnaire and acute muscle fatigue protocol will be applied and Y balance Test, Flamingo Balance Test, Tecnobody Balance Measurement, EMG measurement, anthropometric measurements and digital dynamometer measurements will be made.

Determining the dynamic or static balance of the person will enable us to determine the effect of physical activity levels on the balance in relation to muscle strength and provide us with information about the balance of the person and will give us workable data. Through to these data, we get information about whether the person's level of physical activity is at the desired level. If not, the exercises to be done to reach the desired level or the way the rehabilitation processes to be applied give us important clues in terms of choosing the methods to be applied and determining the direction in which the order will be. If the balance of the person is at the desired level, these data provide us with a great deal of convenience and guide the preservation of this balance.

Knowing the balance data in line with the results to be obtained with this study and using the tests or devices designed in this direction will increase the success of the rehabilitation process and constitute the most important part of the performance increase in physical activity levels.

In case of successful completion of the project, sedentary participants will turn to physical activity to increase their balance. Participants will reduce the risk of falling by increasing their balance by doing physical activity. Therefore, our study will be conducted to investigate the effect of quadriceps muscle fatigue on static and dynamic balance in regular physical activity individuals and sedentary individuals.

Following the approval off the ethics committee, a study will be conducted with 32 regular physical activity individuals and 32 sedentary individuals. The study will start with the approval of the ethics committee and is planned to be completed in May 2022, within 4 months.

Individuals who meet the inclusion criteria and voluntarily accepted to participate in the study will be administered the International Physical Activity Questionnaire Short Form (IPAQ), Mini BESTest, Modified Borg Scale questionnaire and acute muscle fatigue protocol will be applied and Y balance Test, Flamingo Balance Test, Tecnobody Balance Measurement, EMG measurement, anthropometric measurements and digital dynamometer measurements will be made to both regular physical activity individuals and sedentary individuals.
