Brief Summary

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.

Detailed Description

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.

Study Groups

IMT with device

IMT is a therapeutic approach designed to improve respiratory muscle strength and endurance. In this trail, participants will engage in a structured regimen of inspiratory exercises with high resistance.

participants will perform inspiratory muscle exercises using the power-breathe device that provide intermediate to high resistance, with focus on both intensity and volume. The protocol involves 4 to 5 session per week.

Group Type: EXPERIMENTAL

IMT based Resistance training

Intervention Type: 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.

Thera-band resistive training

Participant will engage in a structured training that involving Thera-band resistance training. Participants use different color of thera-band that provides different resistance. The regimen includes 3 session per week using different colors of band.

Group Type: ACTIVE_COMPARATOR

Theraband Resistive training

Intervention Type: 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
