Conditions for interrupting the maximal cycling exercise test. These indications were adapted from [22] introducing more strict criteria to prevent the onset of critical conditions in frail elderlies.

Conditions for test interruption

---

Chest pain suggesting ischemia

ECG changes suggesting ischemia or ectopy

Heart rate exceeding 85% of maximum estimated HR (HR > 0.85 (220 – age – HR^rest) + HR^rest)

Fall in blood pressure (BP_s < BP_s^rest, BP_d < 80 mmHg)

Hypertension (BP_s > min {200 mmHg, BP_s^rest + 10 mmHg} or BP_d > 110 mmHg)

Severe desaturation (SpO₂ < 80%)

Sudden pallor

Dizziness, faintness, or confusion

Loss of limb coordination

Dyspnoea

HR =  heart rate, BP_s =  systolic blood pressure, BP_d = diastolic blood pressure, SpO₂  =  arterial oxygen saturation.
