“…Obese children and adolescents between six and 14 years of age present lesser respiratory muscle strength in comparison with those within the ideal weight range, especially with regard to expiratory capacity, which can compromise ventilatory capacity 25 . This limitation has also been observed in other age groups, demonstrating lesser functional residual capacity in obese adults 26 - 28 . Moreover, excess weight and obesity affect posture, balance, and both upper and lower limb strength 29 , 30 .…”

OBJECTIVE:To compare thoracic musculoskeletal static alterations in adolescents born prematurely with those born at term and investigate neonatal and post-neonatal variables associated with thoracic alterations. METHOD:This is a cross-sectional study with 57 adolescents aged 10-15 years born prematurely and 57 adolescents born at term paired by gender and age. Photographs of the head and thorax in the front, back, and right side views were studied using a computer program. The two groups were compared in regards to: elevation of clavicles, elevation of shoulders, protrusion of the head, and anteroposterior and mediolateral thoracic length. Factor associated with thoracic disorders were evaluated by linear regression analysis. RESULTS:The Preterm group had mean gestational age of 32.0±2.8 weeks and the birth weight was 1462±338 and 3342±430 g for the Preterm and Term adolescents, respectively. Preterm adolescents had higher elevation of the left shoulder (22.7±5.4o vs. 20.6±5.3o;sim, p=0.038) and the right shoulder (22.2±4.4o vs. 18.5±5.7o; p<0.001). Smaller protrusion of the head (27.8±6.1o vs. 32.4±7.9o; p=0.008), mediolateral thoracic length (22.9±2.3 cm vs. 25.1±3.1 cm; p<0.001) and anteroposterior thoracic length (19.7±2.2 cm vs. 21.1±3.4 cm; p<0.001) were found in preterm adolescents. By multiple regression analysis, factors associated with higher shoulder elevation were birth weight <1500 g (p<0.001) and mechanical ventilation during neonatal period >5 days (p=0.009). CONCLUSION:Adolescents born prematurely presented greater thoracic musculoskeletal static alterations compared to those born at term. Factors associated with these alterations were: very low birth weight and longer duration of mechanical ventilation in the neonatal unit.

“…The authors concluded that the pre-or post-developmental phase may modify the influence of age on MRP values, thus demonstrating that anthropometric characteristics may play a small role in determining respiratory muscle strength. Santiago et al 38 later corroborated these results by stating that in overweight/obese children and adolescents, sex, growth factors and hormones may have a greater influence on MRP values than anthropometric variables. It is important to note that in the present study, which used a sample consisting of adolescents, the slight increase in MIP and MEP observed during the growth phase may be related to the physiological changes that occur in puberty 11 .…”

| Background: The literature emphasizes the need for studies to provide reference values and equations able to predict respiratory muscle strength of Brazilian subjects at different ages and from different regions of Brazil. Objectives: To develop prediction equations for maximal respiratory pressures (MRP) of Brazilian adolescents. Method: In total, 182 healthy adolescents (98 boys and 84 girls) aged between 12 and 18 years, enrolled in public and private schools in the city of Natal-RN, were evaluated using an MVD300 digital manometer (Globalmed ® ) according to a standardized protocol. Statistical analysis was performed using SPSS Statistics 17.0 software, with a significance level of 5%. Data normality was verified using the Kolmogorov-Smirnov test, and descriptive analysis results were expressed as the mean and standard deviation. To verify the correlation between the MRP and the independent variables (age, weight, height and sex), the Pearson correlation test was used. To obtain the prediction equations, stepwise multiple linear regression was used. Results: The variables height, weight and sex were correlated to MRP. However, weight and sex explained part of the variability of MRP, and the regression analysis in this study indicated that these variables contributed significantly in predicting maximal inspiratory pressure, and only sex contributed significantly to maximal expiratory pressure. Conclusion: This study provides reference values and two models of prediction equations for maximal inspiratory and expiratory pressures and sets the necessary normal lower limits for the assessment of the respiratory muscle strength of Brazilian adolescents.Keywords: adolescent; respiratory muscles; spirometry; muscle strength; reference values; movement.

“…Studies evaluating these indices of respiratory muscle strength in obese individuals and comparing them with data from eutrophic individuals or normative values have shown no consistent results 3,4,6,7,18,27,28 . Kelly et al 27 found no significant difference in MIP and MEP values among obese individuals (with an average of 183% of the predicted weight) and individuals with an average of 99% of predicted weight, despite a tendency toward lower values among the former.…”
