The gold standard method of measuring [VO.sub.2max] is expired gas analysis during an incremental exercise test to exhaustion using a treadmill or cycle ergometer
. (4,5) However, despite the reliability and accuracy of the gas analysis, its use is limited because it requires expensive high-tech equipment and the assistance of trained personnel.
An individualized aerobic exercise program was designed according to cycle ergometer
Incremental cycle ergometer
tests were also performed before and after four weeks of supplementation.
Immediately after the muscle strength test, endurance was measured using the MOTOmed letto2 cycle ergometer
Peak oxygen uptake and anaerobic threshold were assessed using a maximal exercise test on a cycle ergometer
Tests were separated by 30 min of rest and were performed on a cycle ergometer
(Cyclus II, RBM elektronik-automation GmbH, Germany).
All subjects performed two pre-randomized cycle ergometer
sessions: An HIIT session of 85% to 90% of the subjects' heart rate reserve (HRR), and a continuous aerobic exercise (CAE) session of 60% to 80% of the HRR on non-consecutive days with a minimum interval of 48 hrs.
 Among different available devices, cycle ergometer
(CE) and treadmill (TM) are the most common modalities of indoor AE.
Traditional CR program exercise guidelines are generally conservative: aerobic activity for 30 minutes on a treadmill and/or stationary cycle ergometer
at moderate intensity.
Thereafter, subjects were familiarized with the cycle ergometer
and tested for maximal aerobic power by an incremental cycle ergometer
Intensities for the 30 minutes continuous cycle ergometer
exercise tests were set at 5% below (A) and above (B) the lactate turn point 1, and below (C) and above (D) the lactate turn point 2.
