One approach is to perform a single
graded exercise test and determine Fatmax.
Comparative analysis of physiologic responses to three different maximal
graded exercise test protocols in healthy women.
Maximal Effort and Individual Ventilatory Threshold, we refer to the fact that the maximal effort and individual ventilatory threshold were assessed by a maximal
graded exercise test on a treadmill according to individual abilities as previously done in another authors' study [5].
Schenkman and colleagues confirmed it was safe for the participants to do high-intensity exercise by giving them a cardiologist-supervised
graded exercise test to evaluate the heart's response to exercise.
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).
Its concurrent validity with oxygen uptake, relative maximal oxygen uptake, minute ventilation, respiratory rate, and heart rate during a
graded exercise test on a treadmill has been well studied (r = 0.67-0.88, p < 0.05) [33].

graded exercise test," European Journal of Applied Physiology, vol.
After receiving approval from the local ethics committee and obtaining patients' written informed consent, data from 610 middleaged male marathoners ([greater than or equal to] 40 and <60 years old) who participated in a
graded exercise test (GXT) for a comprehensive physical check-up at our institution between January 2011 and January 2016 were obtained via a manual review of the electronic medical records from our institution's electronic health records.
After the interventions, both groups showed a reduction in ventilatory equivalent ratios for oxygen at matched work rates throughout the
graded exercise test (Figure 2).
Although there is a general consensus that a
graded exercise test (GXT) measuring cardiopulmonary capacity should be performed before entering a cardiovascular rehabilitation program, many patients do not have measures such as ventilatory variables that would assist in appropriate exercise prescription included in these tests.
The second phase of the study consisted of performing a
graded exercise test on a Excalibur Sport cycle ergometer (Lode, The Netherlands).
During the first visit, an HC-only
graded exercise test to exhaustion was performed to determine peak oxygen uptake ([VO.sub.2peak]) and peak aerobic power ([PO.sub.peak]).
