Abstract: A mobile phone apparatus for performing sports physiological measurements and generating target workout information includes a motion detector, a physiological parameter detector, a portable housing, and a processing module. The motion detector detects motion of a user performing exercise, the physiological parameter detector detects physiological parameters of the user, the portable housing houses the processing module, and the processing module is coupled to the motion detector and the physiological parameter detector. The processing module establishes a series of workout stages having varying exercise intensities, estimates at least one of a maximum oxygen uptake quantity ({dot over (V)}O2max) and an anaerobic threshold (AT) of the user performing exercise with reference to data obtained by the motion detector and the physiological parameter detector, and generates target workout information to the user performing exercise.
