Abstract
Objetivo: comparar a aptidão cardiorrespiratória de triatletas, avaliados por testes em bicicleta ergométrica e ciciossimulador (ergômetro mais específico). Métodos: 9 triatletas treinados, 6 do sexo masculino e 3 do sexo feminino, foram submetidos a testes ergoespirométricos em 2 diferentes cicloergômetros, um ciclossimulador e uma bicicleta ergométrica, sendo determinados o consumo máximo de oxigênio (VO2 max), o limiar anaeróbio ventilatório (LA), a freqüência cardíaca máxima (FC max) e a freqüência cardíaca do limiar anaeróbio (FC LA). Resultados: não foram encontradas diferenças significantes entre os testes para nenhuma das variáveis determinadas. Os valores dos testes em ciclossimulador e bicicleta ergométrica foram, respectivamente-. V02 max 62,88 ± 5,13 vs 62,13 ± 6,00 ml/kg/min, LA 37,84 ± 3,75 vs 38,96 ± 4,92 ml/kg/min, FC max 182,00 ± 8,72 vs 180,89 ± 11,16 bpm e FC LA 148,22 ± 6,22 vs 147,89 ± 8,54 bpm. Conclusão: os resultados sugerem que a bicicleta ergométrica pode ser utilizada para avaliação física cardiorrespiratória de triatletas com a mesma precisão do ciclossimulador
Objective: To compare the tri-athietes aerobic power in cardiopulmonary exercise testing on bicycle ergometer and cyclo-simulator (more specific ergometer). Methods: 9 trained triathletes, 6 male and 3 female, perfomed two
cardiopulmonary exercise testing on different cycle ergometers, cyclo-simulator and bicycle ergometer, were measured the maximal oxygen uptake (VO2
max), the ventilatory threshold (VT), the maximal heart rate (HR max) and the ventilatory threshold heart rate (HR VT). Results: no differences were detected between the two tests. The values of cyclo-simulator and bicycle ergometer tests are, respectively - V02 max 62.88 ± 5.13 vs 62.13 ± 6.00 mi. kg-1.min-l, LV 37.84 ± 3.75 vs 38.96 ± 4.92 ml.kg-1.min-1, HR max 182.00 ± 8.72 vs 180.89 ± 11.16 beats.min-1 and HR VT 148.22 ± 6.22 vs 147.89 ± 8.54 beats.min-1.
Conclusion: the results suggest that the bicycle ergometer can be used for cardiopulmonary exercise testing of triathietes with the same precision as that of the cyclosimulator.
