Claim One:
1. A system for identifying a performance period, comprising: a pair of earphones comprising: speakers; a processor; and a heartrate sensor electrically coupled to the processor, wherein the processor is configured to process electronic input signals from the heartrate sensor; and a non-transitory computer-readable medium operatively coupled to at least one of one or more processors and having instructions stored thereon that, when executed by at least one of the one or more processors, cause the system to: identify the user's fitness level progression through a plurality of fitness cycles, each fitness cycle of the plurality of fitness cycles comprises a stimulus, a workout activity type, a workout activity period, and a recovery period, wherein identifying the user's fitness level progression through a plurality of fitness cycles is based in part on determining a fatigue level of the user in each fitness cycle based on signals generated by the heartrate sensor; predict a duration and possible activity types for an optimal future performance period for a future fitness cycle, where the optimal future performance period is calculated based on an interpretive recovery score for each workout activity type detected during the plurality of fitness cycles and a detected current fatigue level, wherein the optimal future performance period begins during the recovery period of a fitness cycle, and wherein the interpretive recovery score is a proportion of a user's fatigue level, wherein the proportion is calculated based on assigned values within a predefined numerical range that are assigned to each of at least one of the user activity type, user activity intensity, duration of user's recent activity and statistical information pertaining to the user's prior activities; and display a recommendation based on the determined predicted optimal future performance period.
