Whole-body vibration exercises associated with pressure threshold device for inspiratory muscular training

Abstract

This work aimed at evaluating the effect of whole-body vibration exercises (WBVE) associated with a pressure threshold device for inspiratory muscular training (IMT). A blind randomized design was carried out with 15 women, divided into two groups: G1 (WBVE and threshold IMT) and G2 (threshold IMT). There was no significant difference (p > 0.05) between maximal inspiratory pressure (MIP) before and after interventions for day 1 (G1: –1 ± 13 cmH2O; G2: +1 ± 8 cmH2O) and day 8 (G1: –1 ± 9 cmH2O; G2: –2 ± 5 cmH2O). However, when comparing measurements before intervention between day 1 and 8, it was found a significant p-value (G1: +30 ± 11 cmH2O; G2: +14 ± 11 cmH2O; p = 0.02). The association of WBVE and pressure threshold IMT led to a significant increase in MIP after 8 sessions, suggesting a benefit in combining these two techniques in clinical practice.
