Resting and warmup variables were not different (p > 0.05) across all trials with the exception of HR, which was higher (p = 0.007, [eta]2 = 0.26) in WAnT versus GXT
Determination of predicted [VO.sub.2]max: A measure of each participant's fitness level was assessed by having each participant complete a submaximal graded exercise test (GXT
) (Balke Protocol) walking on a motorized treadmill.
Ratings of perceived dyspnea (or ratings of perceived breathlessness) were taken immediately following the GXT
. The scale of perceived dyspnea was a 10-point modified Borg Scale (arbitrary units - AU) as used previously (3).
Furthermore, despite lower maximal RER values after the low-PRAL diet, there were tendencies for a longer time-to-exhaustion during the GXT
(p = 0.12) and greater V[O.sub.2]max (p = 0.08).
Considering the findings of the studies that verified the possibility that V[O.sub.2MAX] can be obtained in a progressive test even after induction of lactic acidosis (Simoes et al., 2003; Dantas De Luca et al., 2003), we compared the highest V[O.sub.2] value measured in the incremental phase of LM with the V[O.sub.2MAX] determined during the GXT
. As a hypothesis, we expected similar V[O.sub.2] values from both tests as reported in the literature.
protocol was implemented on treadmill according to BABA's 1996 method,  for 10 min, as designed for children, and increased in terms of exercise time, speed, and slope in which the individual continued to run beyond his lactate threshold, on the treadmill equipped with gas analyzer system (manufactured in Germany).
Logo apos, iniciou-se o GXT
, com carga inicial a 100 watts e incrementos de 25 watts a cada 2 minutos ate a exaustao.
allowed identification of cardiorespiratory fitness (maximum oxygen uptake: VO[sub]2max) and maximum heart rate (HR[sub]max), as well as risk for potentially life-threatening myocardial infarction. A modified Balke protocol was used in the GXT
procedures, wherein the speed of the treadmill was kept below 3 mph and the inclination was increased by 2.5% every 2 min up to a maximum of 20%. Two observers were involved with each patient throughout the GXT
There was one TV channel to start with (Real Time), followed by a bold acquisition that provided additional DTT channels (K2, Frisbee, Focus, GXT
, Giallo), and finally the acquisition of LCN's channel 9 (a full broadcast channel with its four Mux of six Mb/s each) from Gruppo Editoriale L'Espresso, rebranded as "Nove" (Nine).
Salinity treatments (S0mM: 0.00 mM, S50mM: 50 mM, S100mM: 100 mM, S150mM:150 mM) were also significantly different in their effects on lentil genotypes and interaction (GxT
) were also significantly different from each other for subjected traits (Table 1).
Ten subjects (mean [+ or -] SD: age, 23 [+ or -] 1 yrs ; weight, 61.2 [+ or -] 4.9 kg; [VO.sub2] max = 37.6 [+ or -] 2.8 mL[??][kg.sup-1][??][min.sup.-1]) were exposed to the original graded exercise test (GXT
) to determine Wasserman's Anaerobic Threshold (AT), Stegmanan's Individual Anaerobic Threshold (IAT), and Mader's 4 mmol[??][L.sup.-1] Anaerobic Threshold (4mM).
Hill's experiments and a century of observations before him led to the discovery of graded exercise testing (GXT
), the gold standard for quantifying cardiorespiratory fitness (CRF) and measuring V[O.sub.2] during incremental to maximal exercise.
