Heart rate signal processing for a single random sample. Trend = repeated measurements within the 'Exercise' phase of the submaximal cycle ramp test; raw = unaltered heart rate data; Butterworth filtered = heart rate data after low-pass Butterworth filter (heart rate at the beginning and end of the exercise period on this filtered signal used to calculate CRF-vo2max); linear model = fitted heart rate data values from a linear model fitted to the Butterworth-filtered signal (CRF slope is the slope of this linear model)
