The VO2 max is the maximum amount of oxygen muscles can utilize per minute during exercise.

How do smartwatches estimate VO2 max?

Smartwatches estimate VO2 max using indirect measures like heart rate monitoring, unlike direct measurements with a mask in a lab.

What are blood lactate levels used for in tests?

Blood lactate levels are measured during tests to determine aerobic work levels and the accumulation of oxygen debt.

VO2 max tests involve stepping up speeds to find the lactate threshold, pushing until exhaustion, and measuring aerobic capacity accurately.

Running on trails can impact VO2 max scores due to different terrains, affecting heart rate and pace, which can influence the results.

Smartwatches estimate VO2 max through heart rate, offering a convenient and cost-effective alternative to lab tests with accurate benchmarks for personal training progress.
The focus of VO2 max scores on watches is personal improvement and tracking aerobic capacity over time, emphasizing individual progress rather than comparison with elite athletes.

VO2 max is the maximum amount of oxygen muscles can use per minute, usually measured in a lab with expensive equipment or on smartwatches.
Smartwatches estimate VO2 max using indirect measures like heart rate, unlike direct measurements with a mask in a lab.
Blood lactate levels are measured during tests to determine aerobic work levels and oxygen debt accumulation.
Tests involve stepping up speeds to find lactate threshold, pushing until exhaustion, measuring aerobic capacity.
VO2 max tests progress by increasing speed every minute until exhaustion, measuring aerobic capacity accurately.
VO2 max scores on watches aim to show aerobic capacity and progress over time, not for comparison or competition.
Running on trails can impact VO2 max scores due to different terrains, affecting heart rate and pace.
Results from lab tests and watch scores can be close, providing accurate benchmarks for personal progress.
Accurate VO2 max readings on watches can serve as cost-effective benchmarks for training progress.
Personal progress should be the focus, not comparing scores with elite athletes, using VO2 max as a tool for improvement.
