Flight time

摘要

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.

主权项

1. A system for monitoring an athletic performance, comprising:
an input system for:
(a) receiving right foot launch input data from a right foot sensor system relating to a plurality of right foot launch events, wherein the right foot launch input data includes at least a timestamp associated with each right foot launch event indicating a time that respective right foot launch event occurred;(b) receiving left foot launch input data from a left foot sensor system relating to a plurality of left foot launch events, wherein the left foot launch input data includes at least a timestamp associated with each left foot launch event indicating a time that respective left foot launch event occurred;(c) receiving right foot strike input data from the right foot sensor system relating to a plurality of right foot strike events, wherein the right foot strike input data includes at least a timestamp associated with each right foot strike event indicating a time that respective right foot strike event occurred;(d) receiving left foot strike input data from the left foot sensor system relating to a plurality of left foot strike events, wherein the left foot strike input data includes at least a timestamp associated with each left foot strike event indicating a time that respective left foot strike event occurred; and(e)receiving sensor data from a first on-body sensor relating to the plurality of right foot launch events, left foot launch events, right foot strike events, and left foot strike events; a processor system programmed and adapted to:
(a) identify a first set 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;(b) determine 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;(c)determine that the first flight time exceeds a predetermined threshold value, and(d) in response to the determining that the first flight time exceeds the predetermined threshold value, adjust the first flight time associated with the first set of timestamps based on the received sensor data; and an output system for outputting output data including information containing or derived from the first flight time.
