Brief Summary

The study aims to examine the acute effects of balance exercises on balance performance in healthy individuals. It will be conducted with healthy males and females aged 18-25. The research is an experimental study with a single-blind pre-test/post-test design. Initially, participants' balance will be assessed using the Single Leg Stance Test. Then, a short balance exercise program lasting 8-10 minutes will be applied. Exercises include single-leg stance, eyes-closed balance, and unstable surface training. After the exercise, the same test will be repeated to evaluate changes. Perceived exertion will be measured using the Modified Borg Scale. The collected data will be analyzed using SPSS software. The results are expected to contribute to improving balance, performance, and reducing injury risk.

Outcome Measures

Primary Outcomes (3)

• Y-Balance Test Performance

  Measured using the Y-Balance Test (anterior, posteromedial, posterolateral directions) Y Balance Test It is a simple and effective test used to evaluate dynamic balance. The participant is asked to stand on one leg and reach as far as possible in three directions (anterior, posterolateral, and posteromedial) with the non-stance leg. The test is performed in the following order: anterior right, anterior left, posteromedial right, posteromedial left, posterolateral right, and posterolateral left.

  Single assesment at baseline

• Maximum Inspiratory Pressure

  Maximum inspiratory pressure (MIP) is a measure of the strength of the inspiratory muscles and represents the negative pressure generated when an individual inhales as forcefully as possible after a full exhalation.

  Single assesment at baseline

• Maximum expiratory pressure

  Measures the strength of expiratory muscles and is the positive pressure generated during forceful exhalation after a deep breath. It is assessed using a mouth pressure meter (MPM) in a seated position with a nose clip, taking the best of at least three trials.

  Single assesment at baseline

Secondary Outcomes (7)

• The plank test

Study Arms (3)

Low Functional Capacity Group

Participants classified as having low functional capacity according to the predefined functional capacity assessment criteria will undergo evaluation of balance performance, respiratory muscle strength, pulmonary function, vital signs, and core endurance in a single-session assessment.

Other: Assessment of the Relationship Between Respiratory Muscle Strength and Balance

Moderate Functional Capacity Group

Participants classified as having moderate functional capacity according to the predefined functional capacity assessment criteria will undergo evaluation of balance performance, respiratory muscle strength, pulmonary function, vital signs, and core endurance in a single-session assessment.

Other: Assessment of the Relationship Between Respiratory Muscle Strength and Balance

High Functional Capacity Group

Participants classified as having high functional capacity according to the predefined functional capacity assessment criteria will undergo evaluation of balance performance, respiratory muscle strength, pulmonary function, vital signs, and core endurance in a single-session assessment.

Other: Assessment of the Relationship Between Respiratory Muscle Strength and Balance
