Description
Lea Železnik Mežan reviews whether wrist gadgets can honestly measure peak fitness in a 2025 paper. Two gold numbers, the body's max oxygen use and the lactate threshold where effort turns unsustainable, normally need a lab and a mask. Watches now guess both from easy runs, a promise worth auditing.
Following review guidelines, the author sifted 252 records down to thirteen sound studies. Most tested one watch brand paired with a chest strap and its house algorithm. All checked the watch's guesses against treadmill lab tests in everyone from couch sitters to pros. The synthesis weighs where the guesses hold and where they drift, guiding buyers and coaches.
