Systems and methods for monitoring athletic performances include determining “flight time,” e.g., the amount of time both feet are off the ground, and optionally “flight time” resulting from different types of activities, such as jogging, running, sprinting, jumping, etc. “Flight time” may help a player or coach better understand the effort the athlete is putting out, compare efforts of two or more players, gauge the athlete's performance change over time, and/or identify conditioning needs and/or areas for improvement. Such systems and methods also may generate and display various athletic performance metrics, such as: instantaneous flight time; average flight time; cumulative flight time during an athletic performance or other time period; instantaneous jump height; average jump height; cumulative jump height during an athletic performance or other time period; and comparisons of any flight time and/or jump height metric(s) of one player against another player and/or against himself/herself; etc. |

1. A method for analyzing an athletic performance, comprising:
receiving foot launch input data from a foot sensor system relating to a plurality of right foot launch events and a plurality of left foot launch events, wherein the foot launch input data includes at least a timestamp associated with each foot launch event indicating a time that a respective right foot launch event or a left foot launch event occurred; receiving foot strike input data from a foot sensor system relating to a plurality of right foot strike events and a plurality of left foot strike events, wherein the foot strike input data includes at least a timestamp associated with each foot strike event indicating a time that a respective right foot strike event or a left foot strike event occurred; sorting a plurality of timestamps associated with each foot launch event and foot strike event based on a predetermined criteria; identifying a first set of timestamps in the plurality of timestamps, wherein the first set of timestamps includes temporally adjacent right foot launch, left foot launch, right foot strike, and left foot strike events; determining a first flight time associated with the first set of timestamps, wherein the first flight time is based at least in part on a first time duration included by the first set of timestamps when both the left foot and the right foot are simultaneously not in contact with a surface; and validating the determined first flight time based at least in part on the first set of timestamps. |
