Balance & Respiratory Muscle Strength in Healthy Adults

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.

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.

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.

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 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.

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.

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.

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.

Heart rate is the number of beats per minute, normally 60-100 at rest in adults. It will be measured using a pulse oximeter.

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.
