Randomized clinical trial of the Method JaPer to increase inspiratory capacity:Method JaPer to increase inspiratory capacity

Abstract

Introduction: Lung diseases can generate hospitalizations, long stays, complications and even death.

Objective: To analyze the effects of the JaPer method on the inspiratory capacity of hospitalized patients. Materials and methods: Initially double-blind randomized clinical trial with 653 patients that passed to 587

hospitalized patients. Maximum inspiratory capacity was determined through the respiratory incentive, the 6-minute

Results: 587 patients (F: 300 vs M: 287) with an average age of 53.61 ± 14.24 years and where 9.88% of the study population were underweight, 17.89% normal weight and 27.26% and 44.97% overweight and obesity respectively. All participants underwent a 6-minute walk to determine the meters traveled (GE– 387.70 ± 47.59 vs. GC– 371.30 ± 49.10), speed during the test (GE– 64.62 ± 7.93 vs. GC– 61.88 ± 8.18) and the estimated vo2 (GE– 9.96 ± 0.79 vs GC– 9.69 ± 0.82) of each participant. This 6-minute walk as well as the maximum inspiratory capacity (GE– 1708.54 ± 707.84 vs GC– 1448.83 ± 692.79) were determined on the first and last day of pulmonary rehabilitation of the participants.

Conclusions: The experimental group with the JaPer method obtained better results in all the variables evaluated with a significant difference (p = <0.05) compared to the control group. Highlighting that, the maximum inspiratory capacity increased after 2 weeks of training in the experimental group and control group by 44% and 28% (p = <0.05) respectively.
