Key result
In men with restrictive respiratory disorders undergoing physical therapy, an abdominal circumference ≥102 cm was associated with higher inspiratory capacities and systolic blood pressure (p<0.05).
Why the study?
Does respiratory physical therapy improve cardiorespiratory parameters in men with restrictive lung disorders, and does abdominal obesity affect this response?
Observational (n=26)
Does respiratory physical therapy improve cardiorespiratory parameters in men with restrictive lung disorders, and does abdominal obesity affect this response?
Respiratory physiotherapy improves inspiratory capacity and oxygen saturation in men with restrictive lung disorders and abdominal obesity.
May inform therapy tailoring by abdominal circumference in restrictive lung disorders; leaves open need for randomized confirmation.
Purpose: This study aimed to compare cardiorespiratory effects in men with restrictive lung disorders, according to the abdominal circumference (AC), undergoing respiratory physical therapy.Materials and methods: Quasi-experimental study with a sample 26 men with forced vital capacity (FVC)pred <80%, who were divided into two groups: AC (cm) < 102 (ACfree_risk) and ≥ 102 (ACrisk). Heart rate variability (HRV), peripheral oxygen saturation (SpO2), blood pressure (BP), lung capacities and maximal expiratory pressure (PEmax) were measured at rest (T1), immediately after physical therapy intervention (T2), which consisted of breathing exercises for pulmonary expansion, active kinesiotherapy to lower and upper limbs, and after 30 min (T3). The statistical tests used were ANOVA and independent t tests (p < .05).Results: ACrisk had the highest values for slow vital capacity (SVC), inspiratory capacity (IC), PEmax and systolic BP (p < .05); there was an increase in HRV (T2), SpO2 (%) [95.0 (2.5) to 96.6 (1.4)] and IC (l) [2.4 (0.5) to 2.7 (0.6)] (T3).Conclusions: Men with restrictive respiratory disorders and AC ≥102 has higher values in the inspiratory capacities and arterial pressure level, and benefit from respiratory physiotherapy by differential increase in IC.

Martinelli et al. (2018) conducted an observational in restrictive lung disorders (n=26). Abdominal circumference ≥ 102 cm vs. Abdominal circumference < 102 cm was evaluated on slow vital capacity, inspiratory capacity, maximal expiratory pressure, and systolic blood pressure (p=< .05). In men with restrictive respiratory disorders undergoing physical therapy, an abdominal circumference ≥102 cm was associated with higher inspiratory capacities and systolic blood pressure (p<0.05).
