This invention discloses an integrated device and method for testing balance and explosive power, belonging to the field of sports physiology testing and sports equipment technology. The device includes a main body, a pedal fixed to the main body, a partitioned pressure sensor array disposed below the pedal, and a central processing unit. The pressure sensor array is physically divided into independent left-foot and right-foot sensing areas. The central processing unit is configured with two testing modes: in the explosive power testing mode, the vertical jump height of the test subject is calculated based on the free-fall formula by accurately capturing the time interval between the disappearance and reappearance of the pressure signal; in the balance testing mode, the test subject's balance ability is comprehensively evaluated by monitoring the signal triggering and persistence status of the two sensing areas and combining the stability analysis of the pressure signal during single-leg standing. This invention achieves a high degree of hardware and functional integration for two physical fitness tests, featuring accurate measurement, simplified process, and intelligent management.

The application discloses a motion posture analysis method, earphones, an earphone system and a computer readable storage medium. The posture analysis method is applied to the earphones. The method comprises the following steps: acquiring a motion signal, wherein the motion signal comprises an acceleration signal; calculating a running posture parameter based on the acceleration signal, wherein the running posture parameter comprises at least one of a vertical amplitude and a ground contact time, the vertical amplitude represents a vertical displacement variation of the earphones relative to a horizontal plane, and the ground contact time represents a time when a single foot of a user contacts the horizontal plane; and generating prompt information based on the running posture parameter. The vertical amplitude reflects the work condition of the user in the vertical direction, and monitoring the vertical amplitude can guide the user to reduce unnecessary vertical jumping and improve energy utilization efficiency. The ground contact time quantifies the duration of the contact between the foot of the user and the horizontal plane, thereby providing a basis for evaluating the running efficiency and the motion impact force. In this way, the motion posture obtained based on the vertical amplitude and the ground contact time parameter has high accuracy, and the generated prompt information is highly professional.

A jump height measuring device for measuring vertical jump height of a user includes a detector and a microphone, which are communicatively engaged to a microcontroller. The detector is positionable on a surface so it can detect feet of a user upon the surface and communicate a first signal to the microcontroller upon the feet leaving the surface. The microphone is attached to a landing mat, which is positionable on the surface proximate to the detector. The microphone detects a sound of the feet of the user landing upon the landing mat and communicates a second signal to the microcontroller. The microcontroller is programmed to calculate a height of a jump based upon a difference in time between receipt of the first signal and receipt of the second signal. The device also can be used as a timer and to assess Explosive Leg Power Force and response time.
