Comparison of Device Based Inspiratory Muscle Training and Thera-band Resistive Training in Healthy Adults

This study aims to evaluate the impact of inspiratory muscle training and Thera-band resistive training on pulmonary function and diaphragmatic strength of healthy adults. This trail investigate whether IMT can improve pulmonary function and diaphragmatic strength of healthy adults as well as overall respiratory health.

About this study

Inspiratory Muscle Training(IMT) has been shown to improve respiratory muscle strength and endurance in various conditions. This study aims to explore the effects of IMT specifically in healthy young adults. To assess whether a structured IMT program improves diaphragmatic strength and pulmonary function in healthy adults. A randomized control trail involving 56 competitive young healthy adults will be conducted. The study duration will be 8 weeks, with assessments conducted at baseline , mid-point, and at the end of intervention. The IMT group participate in 20 minutes of training session, 4 to 5 times per week, using power-breathe device. Thera-band resistive training group participate in 15 minutes of training session, 3 times per week, using different colors of thera-band. This study aims to provide robust evidence on the benefits of IMT for young healthy adults.

Treatment and study plan

IMT based Resistance training

Other

IMT with device group is trained twice daily, with the morning session and afternoon session. The intensity will increase progressively in this group, starting at 60% Maximal Inspiratory Pressure (MIP) and reaching 75% by the end of study. POSITION: Patient will be in sitting position. FREQUENCY: 4 TO 5 times per week. INTENSITY: 60 to 75% of MIP (gradually increment the load by 10%every 2 weeks to reach 75 to 80 %MIP). Time: 15 to 20 minutes.

Theraband Resistive training

Other

IMT training is form of exercise designed to strengthen the muscle that are involve in inhalation, primarily the diaphragm and intercostal muscles. Thera-band resistive training perform twice daily, with morning and afternoon session. Training will be perform 3 times per week. POSITION: patient will be in standing position. INTENSITY: moderate intensity (black and green thera-band used to provide medium resistance). Time: 15 to 20 minutes

Primary outcomes

  1. Peak Expiratory Flow Rate (PEFR)

    Time frame: 6 weeks

    peak expiratory flow rates measured through digital spirometer.3 zones of measurements are commonly used to interpret peak flow rates. Normal value of PEFR is 80 to 100%.Green zone indicates 80 to 100% normal peak flow reading, yellow zone indicates 50 to 79 %of normal peak flow readings, and red zone indicates less than 50% of normal peak flow reading.

  2. Forced Vital Capacity (FVC)

    Time frame: 6 week

    Forced Vital Capacity (FVC) Forced vital capacity (FVC) measured through digital spirometer. If the value of FVC is within 80% of the reference value, the results are considered normal. Changes in FVC from baseline to 3rd week and after 6 weeks day of intervention will be assessed.

  3. Forced Expiratory volume in 1sec (FEV1)

    Time frame: 6 week

    Forced expiratory volume in 1sec (FEV1) measured through digital spirometer. If the value of FEV1 is within 80% of the reference value, the results are considered normal.
