Overview:
In this module, healthcare providers will learn about the Heart-Fit Score and its importance to health and fitness. They will gain an understanding of the difference between Zone 2 and Heart-Fit Score, as well as the correlation between the Heart-Fit Score and longevity. Coaches will become familiar with 2 methods of calculating the Heart-Fit Score: (1) the Rockport Walk Test and (2) a smartwatch. They will also learn how to interpret the score.
Topic Summary:
- The Heart-Fit Score, also known as VO2 Max, measures maximum amount of oxygen an individual can use at high exertion, and is strongly associated with lifespan and healthspan.
- The Heart-Fit Score gradually declines with age, so maintaining a higher score in young adulthood results in greater reserves in later life.
- The Rockport Walk Test and smartwatches are common, simple methods for determining the Heart-Fit Score.
- The Rockport Walk Test involves walking one mile as fast as possible and measuring the heart rate immediately after completion.
- Smartwatches, including Apple, Samsung, Garmin, and Fitbit, can estimate VO2 Max—although, they are only an estimate.
- The Heart-Fit Score should be evaluated in the context of individual health, and coaches should assist patients in understanding their specific scores.
- Aerobic training (Zone 5) is the most effective zone for improving VO2 max, however, both Zone 2 and strength training can improve Heart-fitness as well.
