This dataset contains physiological and mechanical parameters collected using the HEFMOB prototype during exercise sessions with heart failure patients. Physiological parameters include blood oxygen saturation (SpO₂), heart rate (HR), and blood pressure (systolic and diastolic). Mechanical parameters include cycling speed and pedal resistance. Additional session-specific information includes timestamps, whether the session was paused or stopped, and target values for heart rate and speed. Data is organized per patient and per session. Variables: User_ID: Unique identifier for each patient Timestamps: Time markers for each data point HR: Heart rate (beats per minute) Speed: Cycling speed (e.g., revolutions per minute or km/h) Pedal_Resistance: Resistance level applied to the pedals (from 0 to 8) Pause: Indicates if the session was paused (boolean or binary) Stop: Indicates if the session was stopped (boolean or binary) Target_HR: Target heart rate for the session Target_Speed: Target speed for the session Systolic_BP: Systolic blood pressure (mmHg) Diastolic_BP: Diastolic blood pressure (mmHg)
