Acute effect of respiratory muscle warm-up on explosive power and flexibility performance

The aim of this study is to examine the acute effect of respiratory muscle warm-up on explosive power and flexibility performance. Eighteen sedentary male subjects (n:18, age: 22.44±1.71) voluntarily participated in the study. The subjects were randomly divided into groups as control, placebo and experiment. Acute-hip hamstring, neck trunk, shoulder flexibility and explosive power were measured by applying placebo at 5% of the maximal inspiratory pressure (MIP) value, and respiratory muscle warm-up exercise at 40%, with 2×30 breaths and a 1-minute rest between sets. POWER®breathe, UK brand respiratory muscle training device was used to warm-up the respiratory muscles. The vertical jump test was used for explosive power. SPSS package program was used for statistical analysis of the data. Shapiro-Wilk test was used for normality test. One-way analysis of variance was performed in repeated measurements to analyze the difference between applications. According to the results obtained, a statistically significant difference was found between the applications in the explosive power and sit-reach, neck-trunk flexibility averages (p<0.05). It was determined that the significant differences between the control and experimental groups were in favor of the experimental group. On the other hand, there was no statistically significant difference between the applications in the shoulder flexibility averages (p>0.05). As a result, it can be said that the respiratory muscle warm-up applied to sedentary people positively affects explosive power and flexibility values.
