What people do today

🔧 Fix this

Ideas a builder, maker or community group could start on:

  1. A mobile app that correlates wearable sensor data with user-inputted subjective fatigue ratings to create a personalized fatigue model.
  2. A wearable sensor attachment that measures muscle vibration or electromyography (EMG) signals to estimate muscle fiber exhaustion.
  3. A standardized post-run survey tool that helps runners map physiological data to perceived exertion levels for better trend analysis.
