Subjectes i m\u00e8todes.<\/em> 23 subjectes (10\u00a0homes; 13 dones), IMC 24.3\u2009\u00b1\u20093.1 kg\/m2, edat 32\u2009\u00b1\u200910 anys, f\u00edsicament actius (\u2265\u2009600 METS minut-setmana), van realitzar un test incremental per graons en cicloerg\u00f2metre. Es va registrar el V\u00b7\u2009O2, V\u00b7\u2009CO2, VFC i l\u2019oxidaci\u00f3 de greix per a cada etapa. Per a l\u2019an\u00e0lisi estad\u00edstica es van usar mesures de tend\u00e8ncia central, contrastaci\u00f3 de mitjanes, coeficient de correlaci\u00f3 i an\u00e0lisi de gr\u00e0fics de Bland-Altman. Resultats.<\/em> Els valors per a Fatmax vs. l\u2019UVFC1 van ser de 48.7\u2009\u00b1\u20097.1 vs 55.4\u2009\u00b1\u20099.2 %V\u00b7\u2009O2pic, 68\u2009\u00b1\u200934 vs. 84\u2009\u00b1\u200939 Watts, 112\u2009\u00b1\u200914 vs.125\u2009\u00b1\u200911 lpm i 1.25\u2009\u00b1\u2009.49 vs. 1.41\u2009\u00b1\u2009.54 L\u2009\u00b7\u2009min\u20131, totes les intensitats van presentar difer\u00e8ncies significatives (p\u2009<\u2009.01) i es van identificar correlacions superiors a 0.8 per a W i V\u00b7\u2009O2. El valor de SD1 en Fatmax va ser 5.56\u2009\u00b1\u20092.8 ms. El Fatmax es va situar al 84.2; 90.5 i 90.5% de la c\u00e0rrega en W, FC i \u00adV\u00b7\u2009O2pic de l\u2019UVFC1 respectivament. El valor de 84.2%UVFC1 i SD1\u2009=\u20095 en intensitat de watts no van presentar difer\u00e8ncies significatives (p\u2009><\/em>\u2009.05), correlacions superiors a 0.8, un biaix de \u22483W i bon nivell d\u2019acord amb els valors de Fatmax. Conclusi\u00f3.<\/em> Existeix correlaci\u00f3 entre UVFC1 i el Fatmax en les variables de V\u00b7\u2009O2 i Watts. En utilitzar aquesta relaci\u00f3 es pot identificar la c\u00e0rrega en watts del Fatmax.<\/p>\n\n","protected":false},"excerpt":{"rendered":" Resum Introducci\u00f3.
