| Abstract |
| Background: Inspiratory muscle training (IMT) enhances respiratory function, but its effects on handgrip strength and balance need further study. This research investigates different IMT intensities (30%, 50%, 60% MIP) in sedentary individuals with varying health conditions. Objective: This study examined whether different intensities (30%, 50%, and 60% of Maximum Inspiratory Pressure [MIP]) could effectively enhance inspiratory muscle strength, handgrip strength, and postural balance stability. By assessing these parameters, the research aims to determine the most effective training intensity for optimizing muscular and neuromuscular adaptation. Methods: we conducted a pilot randomized study involving Six participants (37–50 years) across 6–7 sessions. Pre- and post-assessments measured inspiratory muscle strength, handgrip strength, and balance. A paired sample t-test showed statistically significant differences (p = 0.031).Results: Post-assessment data revealed statistically significant improvements in inspiratory muscle strength and handgrip strength and balance across all groups. In inspiratory Muscle Pressure (AMIP, cmH₂O) group 1: Increased from 76.8 to 82, group 2: Increased from 62 to 74.5 , and group 3: Increased from 87.48 to 131. In grip Strength group 1: increased from 27.5 to 32, group 2: Increased from 24 to 30.2, group 3: Increased from 38 to 46.5.The overall Stability Index Group 1: (0.5 → 0.4), group 2: (0.7 → 0.6), and group 3:( 0.6 → 0.4) results show that Group 3 showed the highest improvement in AMIP, grip strength, and balance measures. Conclusion: The results of this study confirm that all three intensities of inspiratory muscle training exert a beneficial influence on handgrip strength, postural balance, and respiratory muscle strength. However, among the tested intensities, the high-intensity training protocol (60% of maximum effort) demonstrated the most pronounced effectiveness in enhancing these physiological parameters |
