Relação da medida da amplitude tóraco-abdominal de adolescentes asmáticos e saudáveis com seu desempenho físico / Relationship of the measure of the amplitude thoracoabdominal in asthmatics and healthy adolescents with the physical performance

RESUMO

Este estudo teve como objetivo verificar as diferenças das amplitudes tóraco-abdominais nos três níveis (axilar, xifoide e abdominal), nos adolescentes asmáticos e nos saudáveis, e compará-las entre eles. Além de relacioná-las com a capacidade de exercício físico. Materiais e métodos: Foram avaliados 38adolescentes, na faixa etária dos 11 aos 15 anos, de ambos os sexos, sendo 19 adolescentes asmáticos, que compuseram o grupo asmático (GA), e 19 saudáveis, que compuseram o grupo saudável (GS). Foi preenchida uma ficha de anamnese e realizada a avaliação antropométrica, espirométrica, o teste do degrau deseis minutos (TD6) e a cirtometria, e calculado o índice de amplitude tóraco-abdominal (IA) Resultados:Observou-se diferença significativa para IA entre os níveis axilar e abdominal e xifoidiano e abdominal em ambos os grupos. Não houve diferença significativa quanto ao IA entre os grupos. Somente no GA houve correlação positiva do número total de subidas no TD6 com o IA axilar e xifoide. Conclusão: Para adolescentes com asma intermitente e persistente leve não houve diferença na cirtometria tóraco-abdominal quando comparados aos saudáveis e houve correlação dos IA axilar e xifoidiano com o desempenho físico no TD6.

ABSTRACT

AIMS: The aims were verify the differences of amplitude thoracoabdominal by cirtometry, at the levels axillary, xiphoid and abdominal in asthmatics and healthy adolescents and to compare the difference between them. In addition correlate them with the physical exercise capacity. MATERIALS AND METHODS: Thirty eight adolescents were assessed, aged from 11 to 15 years, of both sex. Nineteen were asthmatic adolescent, which composed the asthmatic group (AG), and nineteen were health adolescents, which composed the healthy group (HG). A clinical history was provided and all subjects were submitted an anthropometric and spirometric evaluation, the six minute step test (6MST), the cirtometry, and was calculated the amplitude thoracoabdominal index (TAI).RESULTS: Significant difference (p < 0.05) was observed to TAI, between axillary and abdominal levels, and xiphoid and abdominal levels in both group. No significant difference in regard to TAI between groups. Only in the AG there was positive correlation of the total number of ascent in the 6MST with the axillary and xiphoid TAI (r = 0,57 e r = 0,50; p < 0,05). CONCLUSION: There were no difference in the thoracic and abdominal cirtometry in adolescents with intermittent and persistent mild asthma when compared with the healthy adolescents and there were correlation axillary and xiphoid TAI with the physical performance in the 6MST.
