1. Heart rate variability (HRV): HRV refers to the change of heartbeat interval. Higher HRV is closely related to physical health and adaptability. Jiaming equipment evaluates physical strength by measuring heart rate variability.
2. Stress: Jiaming equipment will monitor the stress level, for example, by measuring indicators such as heart rate, breathing and activity to assess the body's stress level. Lower stress levels are associated with higher physical strength.
3, sleep quality: sleep is very important for physical recovery and charging. Jiaming equipment will analyze sleep data, including sleep duration, deep sleep, shallow sleep and other indicators to assess the strength of the body.
