Maximum power and exercise duration values were significantly lower in the 1st TSH quintile than in the 3rd TSH quintile.
Serum TSH levels over the full range were inversely associated with O2/HR in multivariable linear regression, but there was no association with peakVO2, VO2@AT, VE vs. VCO2 slope, maximum power, and exercise duration (Table 2).
Furthermore, we used the following parameters from CPET: peak oxygen uptake (peakVO2), oxygen uptake at anaerobic threshold (VO2@AT), slope of the efficiency of ventilation in removing carbon dioxide (VE vs. VCO2 slope), oxygen pulse (O2HR), maximum power, and exercise duration [ 35].
The following variables will be assessed: total exercise duration (s), maximum exercise HR and blood pressure, maximum rate pressure product (heart rate×blood pressure), time to limiting angina (s) and time to 1 mm ST-segment depression (s).
Shortening the AV interval also raised exercise duration and maximum oxygen consumption and reduced the sensation of breathlessness at peak exercise.
The participants are instructed to record the date, start time, exercise duration and maximum RPE attained during each session in an exercise daily log.
Exercise duration, distance, and maximum speed were recorded at exhaustion.
Subjects will be encouraged to gradually increase their exercise duration to a maximum of 30 minutes over the thirty sessions.
One of the most consistent prognostic markers in exercise testing is maximum exercise capacity, 32 the specific variable (maximum duration of exercise, level of metabolic equivalents achieved, maximum workload, maximum heart rate, double product) used to summarise this being less important.
10 Other studies have shown that A1c has an inverse correlation with maximum oxygen uptake, 11 work capacity 12 and exercise duration.
