About this study
Official title: Is There a Relationship Between Balance and Respiratory Muscle Strength in Healthy Individuals?
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.
Read the detailed description
This study aims to investigate the relationship between balance performance and respiratory muscle strength in healthy individuals. The study will be conducted on healthy adults aged 18-30 years. Participants will be informed about the study procedures and will provide written informed consent prior to participation. Demographic data including age, height, weight, and physical activity level will be recorded. Respiratory function will be assessed using spirometry, and respiratory muscle strength will be measured using maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP). Dyspnea level will be evaluated using the Modified Borg Scale. Vital parameters such as blood pressure, heart rate, and oxygen saturation will be measured before and after assessments. Balance performance will be evaluated using the Y-Balance Test in three directions (anterior, posteromedial, and posterolateral). Additionally, core muscle endurance will be assessed using plank, side bridge, and sit-up tests. All measurements will be completed in a single session following a standardized protocol. The collected data will be statistically analyzed to determine the relationship between balance and respiratory muscle strength.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: 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.
Measured: Single assesment at baseline
Secondary outcomes (7)
The plank test
The plank test evaluates the endurance of deep core muscles (transversus abdominis, multifidus); the individual maintains a prone position supported on the elbows and toes, keeping the body in a straight line, and the duration the position can be held is recorded.
Measured: Single assesment at baseline
Dyspnea Level
Measured using Modified Borg Scale It is a scale commonly used to assess the severity of exertional and resting dyspnea. It consists of ten levels that define the intensity of dyspnea. The clear description of dyspnea severity in the Modified Borg Scale makes it easier to use for patients.
Measured: Single assesment at baseline
Blood pressure
Blood pressure is the force exerted by blood on arterial walls, with a normal value of 120/80 mmHg. It will be measured using an Omron RS1 wrist blood pressure monitor. The systolic and diastolic pressures will be assessed.
Measured: Single assesment at baseline
The lateral bridge (side bridge) test
Lateral Bridge Test measures the endurance of the oblique and lateral trunk stabilizer muscles; the individual lifts the body in a side-lying position supported on the elbow and the side of the foot, keeping it in a straight line, and the duration the position can be maintained is recorded.
Measured: Single assesment at baseline
The sit-up test
The sit-up test evaluates the endurance of the abdominal flexor muscles; the individual lies supine with knees bent, lifts the trunk to a sitting position, and performance is measured by the number of repetitions or within a set time.
Measured: Single assesment at baseline
Heart Rate
Heart rate is the number of beats per minute, normally 60-100 at rest in adults. It will be measured using a pulse oximeter.
Measured: Single assesment at baseline
Oxygen Saturation
SaO₂ represents the oxygen level in the blood, normally 95-100% in healthy individuals. It will be measured using a pulse oximeter.
All parameters will be assessed before and after the tests.
Measured: Single assesment at baseline
