Brief 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.

Detailed Description

Effective respiratory function is crucial for swimmers, given the demanding nature of the sport. Inspiratory muscle training (IMT) has been shown to improve respiratory muscle strength and endurance in various populations. This study aims to explore the effects of IMT specifically on competitive swimmers, assessing both physiological and performance-related outcomes. To assess whether a structured IMT program improves swimming performance, respiratory muscle strength, and overall respiratory efficiency in recreational swimmers. A randomized controlled trial involving 56 competitive swimmers will be conducted. The study duration will be 8 weeks, with assessments conducted at baseline, mid-point, and at the end of the intervention. The IMT groups will participate in a 20-30 minute training session, 4 to 5 times per week, using power breath device . The training will focus on enhancing inspiratory muscle strength and endurance. This study aims to provide robust evidence on the benefits of IMT for swimmers, potentially informing future training practices and enhancing competitive performance.

GroupInterventionDescription
High volume intensity (HVIMT)Assigned interventions for HVIMTHigh-volume intensity inspiratory muscle training (IMT) is a therapeutic approach designed to improve respiratory muscle strength and endurance. In this clinical trial, participants will engage in a structured regimen of inspiratory exercises with high resistance and significant repetition volume. Participants will perform inspiratory muscle exercises using power breath that provides high resistance, with a focus on both intensity and volume. The protocol involves 3 sessions per day for 6 weeks.
Low volume intensity LVIMTAssigned Interventions for LVIMTParticipants will engage in a structured training program involving inspiratory muscle exercises with high resistance and a high volume of repetitions. The regimen includes multiple sessions per day over several weeks, using specialized inspiratory muscle training devices. Changes in inspiratory muscle strength (measured by maximal inspiratory pressure) and endurance.
Primary Outcome Measures
NameTimeMethod
Peak Expiratory Flow Rate (PEFR)6 weeks

Peak expiratory flow rate (PEFR) Peak expiratory flow rate (PEFR) measured through digital spirometer. Peak Expiratory Flow Rate (PEFR) measured through digital spirometer. Three zones of measurement are commonly used to interpret peak flow rates. Normal value of PEFR is (80-100%). Green zone indicates 80 to 100 percent of the usual or normal peak flow reading, yellow zone indicates 50 to 79 percent of the usual or normal peak flow readings, and red zone indicates less than 50 percent of the usual or normal peak flow readings.

Forced Vital Capacity (FVC)6 weeks

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.

Forced Expiratory volume in 1sec (FEV1)6 weeks

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.

Swimming efficiency (SWOLF) score6 weeks

A SWOLF score is a metric used in swimming to assess efficiency. It combines the time it takes to swim a distance (in seconds) with the number of strokes taken to complete that distance.
