Abstract: An adaptive training system can determine a finite work capacity and critical power and use those determinations to generate an adaptive training programs for workout parameters. To determining a finite work capacity and critical power, the adaptive training system can receive workout data; generate data points by determining, for each workout, a maximum amount of work done for each of multiple time window sizes; fit these workout data points to a function; and determine a critical power and finite work capacity based on the fitted function. Once the adaptive training system has determined a critical power and finite work capacity, the adaptive training system can use them to generate an adaptive training program by keeping a function defined by a set of workout parameters below an ability function that is based on the critical power and finite work capacity.

Abstract: A user-specific workout can be generated by adjusting transform parameters of a user-agnostic training profile to conform to a user boundary specifying a user's ability to perform work. The user-agnostic training profile can be defined in a training space, specifying a power curve in a time domain whereas the user boundary can be defined in a boundary space, specifying amounts of user-produced work in a time window size domain. A training boundary can be generated based on the user-agnostic training profile by determining the largest area under the user-agnostic training profile power curve for various time window sizes, where each largest area under the user-agnostic training profile power curve produces a data point for the training boundary for that window size domain value. The training boundary can be transformed based on the user boundary, causing corresponding transformations to the user-agnostics training profile, converting it to a user-specific workout.

Abstract: A method of controlling reverse thrust by a propulsion device on a marine vessel includes determining that the propulsion device is situated to effectuate a reverse thrust and determining an initial trim position of the propulsion device. An engine RPM or an engine torque of the propulsion device is then controlled to effectuate a reverse thrust, and a trim position of the propulsion device is monitored. If a threshold increase in trim position from the initial trim position is detected at an increased engine RPM or an increased engine torque, then a reverse thrust limit is calculated based on the increased engine RPM or increased engine torque. The engine RPM of the propulsion device is then controlled so as not to exceed the reverse thrust limit while the propulsion device is effectuating the reverse thrust.
