Acute effect of inspiratory muscle warm-up protocol on acceleration and maximal speed of 12-14 age children

The aim of this study is to investigate the effect of the inspiratory muscle warm-up protocol on acceleration and maximal speed in children aged 12-14. Thirty sedentary boys (age: 12.63 ± 0.89 years) participated in the study. Participants were randomly included in 4 different trials (T1, T2, T3, T4). Acceleration (10m, 20m) and maximal speed tests (30m, 50m) were randomly tested at 10 minutes intervals in each trial. Acceleration and speed tests were performed without any warm-up in T1 trial, with general warm-up in T2 trial, placebo inspiratory muscle warm-up in T3 trial, and inspiratory muscle warm-up in T4 trial. As a result of the statistical analysis, it was seen that general warm-up (T2) and inspiratory muscle warm-up (T4) increased performance significantly compared to control (T1) and placebo (T3) trials in all acceleration and speed tests (p <0.05). In conclusion, it can be said that the inspiratory muscle warm-up protocol has positive effects on acceleration and maximal speed performances, similar to general warm-up.
