- Sleep Tracking: Monitors sleep stages (light, deep, REM) and provides insights into sleep quality and duration.
- Electrocardiogram (ECG): Detects irregular heart rhythms and provides data that can be shared with healthcare providers.
- Blood Oxygen Levels (SpO2): Measures the oxygen saturation in the blood, which is crucial for understanding respiratory health and altitude adaptation.
- Respiratory Rate: Tracks the number of breaths per minute, providing insights into respiratory function and overall fitness.
- Muscle Activity (EMG): Some advanced wearables measure electromyography (EMG) signals to analyze muscle activity and fatigue.
The Science of Biofeedback – Wearable Tech
What is Biofeedback?
Biofeedback is a technique that involves monitoring physiological functions and providing real-time feedback to the user. This feedback can be used to gain control over these functions and improve health and performance. In the context of wearable technology, biofeedback involves the continuous monitoring of metrics such as heart rate, HRV, muscle activity, and more.
How Biofeedback Works – Wearable Tech
Wearable devices are equipped with sensors that detect various physiological signals. These signals are then processed by algorithms to provide meaningful insights. For example, optical sensors in smartwatches measure heart rate by detecting changes in blood volume, while accelerometers and gyroscopes track movement and activity levels. Advanced devices use electrodes to measure electrical activity in the muscles (EMG) or the heart (ECG).
The data collected by these sensors is analyzed and presented to the user through an app or display. This real-time feedback allows users to understand how their body responds to different activities, stressors, and recovery periods. By interpreting this data, users can make informed decisions about their training and lifestyle.
