1. A method for improving an accuracy of a wearable device while estimating energy expenditure of a user during a swimming session, the method comprising:

  • collecting, by a motion sensing module of a wearable device, motion data of the user;

    determining, by a processor circuit of the wearable device, rotational data of the user based on the motion data;

    counting, by the processor circuit, a number of strokes made by the user based on the set of rotational data;

    estimating, by the processor circuit, a stroke rate of the user based on the number of strokes;

    counting, by the processor circuit, a number of laps finished by the user based on the set of rotational data;

    calculating, by the processor circuit, a stroke length based on the number of strokes, the number of laps finished, and a lap length associated with the swimming session;

    calculating, by the processor circuit, a speed of the user based on the stroke rate and the stroke length;

    estimating, by the processor circuit, an efficiency of the user based on at least one of the stroke length or a level of stroke orbit consistency of the user;

    classifying, by the processor circuit, a swimming style of the user based on the set of rotational data;

    determining, by the processor circuit, an energy expenditure of the user based on the speed, efficiency, and swimming style of the user; and

    outputting, by the processor circuit, the determined energy expenditure of the user.
