Resumo: | The objective of this study was to evaluate the influence of different body sizes on the cardiorespiratory responses of 10-13-year-old boys during the stages of a maximum-effortincremental test. Twenty boys underwent a continuous maximal incremental test on a cycle ergometer at an initial power output of 30 W and subsequent increases of 30 W at intervals of 3 min. Respiratory variables were assessed with a metabolic gas analyzer on a breath-by-breath basis. Heart rate was monitored continuously during the test. The groups were divided a posteriori according to maximal work output in the incremental test (90 or 120 W) and according to body weight (> 45 or < 45 kg). The following variables were continuously measured: respiratory frequency, tidal volume, ventilation, absolute and relative oxygen uptake, carbon dioxide production, heart rate, and ventilatory equivalent for oxygen. The anthropometric variables, especially height and body weight, were closely associated with the cardiorespiratory responses. These variables are limiting and determinant factors of performance and need to be included in the prescription and practice of physical exercise for this pediatric population. |

Influence of anthropometrics variables on the cardiorespiratory responses of children during exercise.Influência das variáveis antropométricas nas respostas cardiorrespiratórias de crianças durante o esforçoThe objective of this study was to evaluate the influence of different body sizes on the cardiorespiratory responses of 10-13-year-old boys during the stages of a maximum-effortincremental test. Twenty boys underwent a continuous maximal incremental test on a cycle ergometer at an initial power output of 30 W and subsequent increases of 30 W at intervals of 3 min.

Vinte meninos realizaram um teste incremental máximo em cicloergômetro com carga inicial de 30 W e incrementos subsequentes de 30 W a cada três minutos. As variáveis respiratórias foram medidas respiração-a-respiracão através de um analisador metabólico de gases. A frequência cardíaca foi constantemente monitorada durante o teste. Os grupos foram divididos a posteriori em função da carga máxima atingida no teste incremental (90 ou 120 W) e em função da massa corpora (maior ou menor que 45 kg). As seguintes variáveis foram mensuradas continuamente: frequência respiratória, volume corrente, ventilação, consumo de oxigênio absoluto e relativo, produção absoluta de gás carbônico, frequência cardíaca e equivalente ventilatório de oxigênio. Foi concluído que as variáveis antropométricas, especialmente estatura e massa corporal, mostram-se estreitamente relacionadas às respostas cardiorrespiratórias, apresentando-se como fatores determinantes e limitantes do desempenho, devendo ambas ser consideradas para a prescrição e prática de exercícios físicos desta população pediátrica.Universidade Federal de Santa Catarina.
