Efeitos do uso da máscara para análise de gases sobre variáveis fisiológicas e perceptuais máximas e submáximas durante um teste incremental

Abstract: Rev Bras Educ Fís Esporte, (São Paulo) 2016 Jul-Set; 30(3):533-40 • 533 Effects of the use of the mask for gas analysis in the incremental test IntroductionThe effects of the use of the mask for gas analysis on the submaximal and maximal physiological and perceptual variables in response to an incremental test CDD. 20.ed. 796 e maximum aerobic velocity (MAV) predicts running performance of middle and long distance athletes 1-2 . Moreover, it can be used in the control and prescription of exercise training 3… Show more

“…When we evaluate in a fractional way, without the constant use of the gas analysis mask, the increase of the tLim EXTR could be explained by the unrestricted access to ambient air and the lesser sensation of fatigue. Whereas in the tLim C , the use of the mask can theoretically prevent access to O 2 or CO 2 withdrawal as needed, increasing the sensation of fatigue due to increased cardiorespiratory and/ or metabolic stress (i. e. high CV = 18.5 % of [La -] PEAK ) [22][23][24][25]. Thus, it is clear that the increase of the tLim EXTR (more than 3 min) along with low homogeneity of the accumulated VO 2 measurement may have directly influenced the calculation of the MAOD EXTR by adding random errors (low and insignificant ICC, and low homogeneity in the sample TE and CV), compromising its reliability.…”
