1. A method for coordinating cardiovascular pump timing with detected musculoskeletal pump timing to facilitate favorable cardiovascular hemodynamics in an individual, the method comprising:

  • accessing ongoing signals from at least one musculoskeletal activity sensor positioned in or on an individual;

    processing the accessed signals from the musculoskeletal activity sensor;

    detecting from the processed signals that the individual is engaged in a rhythmic physical activity, the rhythmic physical activity having an associated musculoskeletal pump timing;

    determining a target cardiovascular pump timing for the individual, which would achieve favorable cardiovascular hemodynamics during the rhythmic physical activity;

    determining a target heartrate corresponding to the rhythmic physical activity;

    determining whether an intrinsic heartrate of the individual is less than or equal to the target heartrate; and

    when the intrinsic heartrate is less than the target heartrate, providing a pacing signal to the heart of the individual to pace the heart at the target heartrate and the target cardiovascular pump timing such that a maximal musculoskeletal pumping of blood occurs substantially during cardiac diastole.
