          Abstract

          Nas últimas décadas, vários trabalhos sobre respiração bucal (RB) têm surgido na literatura; em contrapartida, pouco se conhece sobre vários aspectos desta síndrome, incluindo gravidade, repercussões sobre o rendimento físico e escolar. OBJETIVO: Comparar o rendimento físico pelo teste de caminhada de seis minutos (TC6') e rendimento escolar de crianças e adolescentes com RB e respiradores nasais (RN). MÉTODO: Estudo de corte transversal descritivo e prospectivo em crianças RB e RN que foram submetidas ao TC6' e avaliação do rendimento escolar. RESULTADOS: Foram incluídos 156 escolares, 87 meninas (60 RN e 27 RB) e 69 meninos (44 RN e 25 RB). Foram analisadas variáveis durante o TC6': frequência cardíaca (FC), frequência respiratória, saturação periférica de oxigênio, distância percorrida em seis minutos e escala de Borg modificada. Todos os valores das variáveis estudadas foram estatisticamente diferentes entre os grupos RB e RN, com exceção do rendimento escolar e FC no TC6'. CONCLUSÃO: A RB afeta o rendimento físico e não o rendimento escolar, sendo observado padrão alterado no TC6' no grupo RB. Uma vez que os RB desse estudo foram classificados como não graves outros estudos comparando as variáveis de rendimento escolar e TC6' são necessários para o melhor entendimento do processo dos desempenhos físico e escolar em crianças com RB.

          In recent decades, many studies on mouth breathing (MB) have been published; however, little is known about many aspects of this syndrome, including severity, impact on physical and academic performances. OBJECTIVE: Compare the physical performance in a six minutes walk test (6MWT) and the academic performance of MB and nasal-breathing (NB) children and adolescents. METHOD: This is a descriptive, cross-sectional, and prospective study with MB and NB children submitted to the 6MWT and scholar performance assessment. RESULTS: We included 156 children, 87 girls (60 NB and 27 MB) and 69 boys (44 NB and 25 MB). Variables were analyzed during the 6MWT: heart rate (HR), respiratory rate, oxygen saturation, distance walked in six minutes and modified Borg scale. All the variables studied were statistically different between groups NB and MB, with the exception of school performance and HR in 6MWT. CONCLUSION: MB affects physical performance and not the academic performance, we noticed a changed pattern in the 6MWT in the MB group. Since the MBs in our study were classified as non-severe, other studies comparing the academic performance variables and 6MWT are needed to better understand the process of physical and academic performances in MB children.

            Six-minute walk test-normal values of school children aged 7-12 y in India: a cross-sectional study.

            To establish normal reference standards for six minute walk test of children aged between 7-12 y in India. Healthy children aged between 7 to 12 y were recruited randomly from the selected schools in India. 400 children were included .Six minute walk test (MWT) was performed according to standardized ATS guidelines. Distance walked in 6 min, Heart rate (HR), Blood pressure (BP), Oxygen saturation, anthropometric measurements and level of dyspnea were taken as outcome measures. Mean distance walked in 6 min was 609 ± 166 m, with significant difference between boys and girls( p < 0.001). Boys covered more distance than girls. Heart rate increased from a baseline of 82.73 ± 1.63 to a maximum of 104.32 ± 3.11; heart rate recovery occurred at 5 min in both the genders. SBP increased from baseline 109 ± 2.38 to maximum of 121.86 ± 1.75 at the end of the test, with no significant increase in DBP which was 68.51 ± 2.21 and 69 ± 2.78 at the end of the test. No significant change in oxygen saturation and dyspnea was observed during the test. Mean oxygen saturation was 97% at baseline, with an immediate drop of 96%. In this study, the mean distance covered in 6 min by boys was 670.74 ± 86.21 m and girls were 548.93 ± 44.78 m.

              Correlation between 6-min walk test and exercise stress test in healthy children.

              To investigate the correlation between 6-min walk test (SMWT) and incremental treadmill exercise stress test (EST) as indicators for the functional capacity in children. Healthy children aged 9-12 years were included. The anthropometric data, SMWT and EST were prospectively measured using the standard protocols. Various parameters were analysed to define the correlation between SMWT and EST. A total of 100 subjects (53 boys) aged 10.3 +/- 1.0 years participated in the study. The SMWT distance was 586.1 +/- 44.0 m. Height (r = 0.59, R(2) = 35%), length of the leg (r = 0.64, R(2) = 41%), heart rate at the end of SMWT (r = 0.59, R(2) = 35%) and heart rate difference at the end of SMWT (r = 0.71, R(2) = 50%) were found to have significant correlation with SMWT distance. The estimated maximal oxygen consumption (eVO2) obtained during the EST tended to be greater in boys than in girls. Among the parameters obtained during EST, maximal heart rate (r = 0.33, R(2) = 11%) and the eVO2 (r = 0.54, R(2) = 53%) were found to have significant correlation with SMWT. SMWT distance is significantly correlated with the eVO2 obtained during the EST. This indicates that SMWT is also one of the predictive markers for EST performance.
