O limiar de esforço percebido (LEP) corresponde à potência crítica e a um indicador de máximo estado estável de consumo de oxigênio

Abstract: The perceived exertion has been a target of several investigations, many times with association with objective physiological indicators in exercise. Recently, the identification of the perceived exertion threshold (PET) was proposed in the water running, which presented no difference in relation to the critical velocity. Theoretically, both parameters would be indicators of the maximum steady state of variables such as VO 2 and blood lactate. The objective of this work was to verify the coincidence between PET… Show more

“…The VO 2 peak concerning the body weight reached by the canoers (51.9 ± 5.6 ml/kg/min) may be considered high, since comparatively it was higher than the values reported in young individuals, in its majority non-athletes, who performed maximal test in cycle ergometer for lower extremities (46.7 ± 8.5 ml/kg/min), in a previous study conducted by our group (11) . Besides the greater muscular mass used by the lower segment of the body in a maximal exercise, which would justify a wide advantage of the legs in uptaking oxygen, there is the extra factor that the O 2 cogency in the upper extremities is lower than in the lower extremities, which can be credited to factors such as heterogeneity in the blood flow distribution for the different muscles or functional portions of the same muscle, times of mean transit in the differentiated capillars, as well as areas of different diffusion (12) .…”

“…Caso essa resposta possa ser relacionada a parâmetros de sobrecarga, as escalas de percepção de esforço poderiam ser utilizadas com mais freqüência no contexto do planejamento e prescrição do treinamento de nadadores. Combinando os pressupostos do modelo de velocidade crítica com as noções mais atuais de esforço percebido, foi proposto, recentemente, o limiar de esforço percebido (LEP) (19,20) . Em tese, o LEP corresponde ao máximo estado estável de percepção de esforço, além de apresentar alta correlação com a potência crítica, VC e com um indicador do máximo estado estável do consumo de oxigênio (19,20) , sendo desta forma um demarcador de transição metabólica entre o domínio intenso e severo de exercício (9) .…”

Adicionalmente, foi observado nesses dois estudos que em intensidades superiores a VC, o esforço percebido aumentava em função do tempo a uma taxa proporcional à intensidade.…”
