Apple Watch estimates VO₂ max from submaximal exercise, but how accurate is it?
In our study of 40 adults, it underestimated VO₂ max by ~6 ml/kg/min—often a whole fitness category.

Wearables like Oura, WHOOP + Garmin give you a single “readiness” score.
Our new review shows most rely on just 2 metrics (RHR + HRV), with opaque algorithms + overlapping inputs.
Good for trends, not daily judgment. 📄 doi.org/10.1515/teb-...

We reviewed the privacy policies of 17 wearable brands.
Most fall short. Some don’t say who can access your data—or what they’d do if it leaked.

Should rules be stricter?

Can you exercise too much?
Studies suggest that extreme exercise doesn't significantly raise mortality risks compared to moderate levels.

AI in academia: a 'Jagged Frontier.' Inside, AI boosts efficiency in admin, content creation, and grading. Outside, it falls short in mentoring, ethics, and original research. On the frontier, AI is emerging in data analytics and interactive learning.
