Smartwatches from companies like Apple and Garmin now make it possible to easily monitor a crucial health metric called VO2max, which measures the amount of oxygen a body can utilize during intense exercise. The higher the VO2max, the better an individual’s heart health and overall longevity. While previously, only professional athletes underwent the traditional VO2max test that required wearing complex sensors while exercising in a lab, smartwatches now allow anyone to measure their VO2max by just walking around.
However, questions arise regarding the accuracy of the data provided by these smartwatches. After months of relying on his Apple Watch for data on his VO2max, the author discovered some unpleasant truths about his health and the limitations of smartwatches. Although his smartwatch showed his VO2max was a little low, his gym membership and diligent exercise improved the estimate. When he did a clinical VO2max test in a lab, however, the results were vastly different, indicating a poor number.
This discrepancy experienced by the author highlights the pros and cons of utilizing smartwatch data to track health. On one hand, it motivates individuals to exercise and take their health seriously, but on the other hand, it can sometimes provide inaccurate or incomplete data.
Experts advise not taking the numbers on smartwatches too seriously, as various factors can impact the accuracy. Loose wrist straps, faulty sensors, and imperfect algorithms can all give inaccurate readings. The most important aspect is to monitor progress and determine whether numbers are going up or down.
Despite the limitations, smartwatches can still be an effective tool for maintaining a healthy lifestyle. By focusing on the bigger picture and not getting caught up in exact figures, individuals can use wearable technology to foster healthy habits and achieve their health goals.
