Purpose: The aim of this research was the effect of 4 weeks of interval training and Inspiratory Muscle Training (IMT) on the initial recovery of respiratory muscle strength in inactive people. Method: This research was semi-experimental. The statistical sample of this research consisted of 30 healthy and inactive students of Shahrood University of Technology with an average age of 30±10 years. Subjects were randomly divided into 3 groups (IMT, Interval and Sham exercises). Interval exercises were performed submaximal with a training frequency of 3 and 4 days per week and training intensity between 40-60 and 50-70% of reserve heart rate for the first and last two weeks, respectively. IMT exercises were performed with a training frequency of 4 and 5 days and an intensity of 50 and 60% of maximum inspiratory strength and with 30 breathing efforts in each session for the first and last two weeks, respectively. The exercises of the sham group were performed in the same way as the IMT group, but with 10 and 15% intensities for the first and last two weeks, respectively. The parametric test of one-way analysis of variance with repeated measurement and dependent t-test with 95% confidence was used with SPSS 26 software.Results: Inspiratory muscle strength showed a significant increase in IMT and interval training groups (P0.05), the largest decrease was related to the IMT and sham exercise groups, and the interval exercise group experienced a smaller decrease than the other two groups.Conclusions: It seems that IMT training is more effective than interval training in increasing the strength of respiratory muscles and improving the return to the initial state of the strength of these muscles.
