About this trial

This study aims to examine the effects of blood flow restriction (BFR) exercises on back muscle endurance and balance in healthy young adults. BFR is a training method that involves applying controlled pressure to the limbs with a cuff while performing simple exercises. It has been shown to improve muscle strength and endurance even at low exercise loads, reducing stress on the joints.

In this study, participants aged 20 to 25 years will be randomly assigned to two groups. One group will perform sit-to-stand (STS) exercises combined with BFR, while the other group will perform the same exercises without BFR. The exercise program will last 6 weeks, with 2 sessions per week.

Before and after the program, participants will be assessed for:

Lumbar extensor muscle endurance (using the Biering-Sørensen test)

Balance performance (using a computerized balance platform)

Physiological responses such as oxygen saturation, heart rate, and blood pressure

The purpose of this research is to determine whether BFR exercises improve spinal muscle endurance and balance more effectively than standard sit-to-stand exercises. The results may provide new insights into the use of BFR training as a safe and practical strategy for improving posture, preventing back problems, and enhancing physical performance in young adults.

Treatments tested in this trial

  • Blood Flow Restriction Sit-to-Stand Exercise

    Behavioral

    Participants perform sit-to-stand (STS) exercises with blood flow restriction applied using a pneumatic cuff placed on the thigh. Cuff pressure is set at 60-80% of the participant's systolic blood pressure. Sessions are supervised by a physiotherapist twice per week for six weeks.

  • Sit-to-Stand Exercise without Blood Flow Restriction

    Behavioral

    Participants perform the same sit-to-stand (STS) exercise protocol as the experimental group, but without blood flow restriction. Sessions are supervised twice weekly for six weeks, and outcomes are assessed before and after the program.

Trial outcomes

Primary outcomes

1

Lumbar Extensor Muscle Endurance

Endurance of the lumbar extensor muscles will be assessed using the Biering-Sørensen Test. Participants maintain the upper body in a horizontal position while lying prone with the pelvis stabilized. The test duration (in seconds) until trunk decline \>5-10° will be recorded.

Time frame
Baseline and after 6 weeks of intervention
2

Postural Balance Performance

Balance performance will be evaluated using a computerized balance platform (TechnoBody™ Pro-Kin). Both static and dynamic balance parameters will be recorded. Outcome measures include sway area (cm²), sway velocity (cm/s), and postural stability index.

Time frame
Baseline and after 6 weeks of intervention

Secondary outcomes

1

Change in Oxygen Saturation

Peripheral oxygen saturation (SpO₂, %) will be measured using a pulse oximeter placed on the finger. Measurements will be taken before and after exercise sessions, and changes from baseline to week 6 will be recorded.

Time frame
Baseline and immediately after exercise sessions (pre- and post-intervention at 6 weeks)
2

Change in Blood Pressure

Systolic and diastolic blood pressure will be measured using a validated digital sphygmomanometer. Measurements will be taken at rest before and after exercise sessions. The change from baseline to week 6 will be compared between groups.

Time frame
Baseline and immediately after exercise sessions (pre- and post-intervention at 6 weeks)
3

Change in Body Mass Index (BMI)

Body mass index (kg/m²) will be calculated from height and weight measured with a digital body composition analyzer (Tanita device). Changes from baseline to week 6 will be analyzed.

Time frame
Baseline and after 6 weeks of intervention
