Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Agreement between sweat lactate threshold (sLT) and ventilatory threshold (VT) in patients who underwent cardiopulmonary exercise testing (CPX), assessed by correlation coefficient and Bland-Altman analysis. The evaluation will be performed at baseline (registration). | — |
Secondary
| Measure | Time frame |
|---|---|
| Success rate of sweat lactate threshold (sLT) measurement in all subjects, determined by three independent evaluators. Evaluation at baseline (registration). Association of sLT with exercise heart rate, Borg scale, and walking distance. Evaluation at baseline (registration). | — |
