Comparison of High Volume Intensity Training and Low Volume Intensity Training With IMT on Pulmonary Function and Breathing Efficiency of Recreational Swimmers

Riphah International University·interventional·Posted Sep 19, 2024·Updated Aug 19, 2025

In Brief

A clinical study evaluating Assigned Interventions for LVIMT and Assigned interventions for HVIMT for Healthy Young Adults. Completed, enrolled 64 participants across 1 site.

Detailed Summary

This study aims to evaluate the impact of inspiratory muscle training (IMT) on respiratory function and swimming performance in competitive swimmers. Given the importance of optimal respiratory function in swimming, this trial investigates whether IMT can improve swimming performance metrics, such as lap times and endurance, and overall respiratory health.

Interventions

Assigned Interventions for LVIMTother

IMT is a form of exercise designed to strengthen the muscle involved inhalation, primarily the diaphragm and intercostal muscles. The LVIMT group will perform IMT once daily, 5 days a week, maintaining 60% of maximal inspiratory pressure (MIP) throughout the 6-week intervention. The intervals are typically longer in duration (e.g., 2-4 minutes) with a work-to-rest ratio of 1:1 or 1:0.5. POSITION: rested and seated position. FREQUENCY: more frequency, once a day. 2-3 sessions per week. INTENSITY: Low resistance. Only 60%% MIP. TIME: shorter duration of 10-20 mint.

Assigned interventions for HVIMTother

The HVIMT group is trained twice daily, with the morning session matching the LV-IMT protocol, and an additional afternoon session. The HVIMT group also experienced a progressive increase in intensity, starting at 60% MIP and reaching 80% by the end of the study. LVIMT works for beginner or individuals with limited respiratory capacity while HVIMT is used for individual with high baseline respiratory fitness. The intervals are typically shorter in duration (e.g., 30 seconds to 2 minutes) with a work-to-rest ratio of 1:1 or 1:2. POSITION; Seated upright position. FREQUENCY: more frequency two session per week. 4-5 sessions per week. INTENSITY: high resistance. 60%-80% MIP. (gradual increment the load by 10% every 2 weeks to reach 80% MIP) TIME: longer duration 20-30 mint.
