Summary

This study is testing whether wearable sensors, like those in smartwatches, can accurately estimate a key measure of heart and lung fitness called VO2Max during everyday activities. Researchers will collect data from 1,000 participants, including healthy volunteers and patients undergoing standard exercise tests. The goal is to develop a machine learning algorithm that could make fitness tracking more accessible without needing special lab equipment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could lead to a simple way to measure heart and lung fitness using wearable devices, making it easier for people to track their health without needing a lab test.
What could go wrong: This is an early observational study focused on data collection, not a treatment. The algorithm may not be accurate enough for widespread use, and results may not apply to everyone.
