Is it Time to Step Up Your Workout Routine?
The Rockport Walk Test: A Simple Way to Measure Your Aerobic Fitness
Losing weight and getting in shape are popular New Year’s resolutions — but before you join a gym with the masses, it may help to determine your current fitness level. Enter the Rockport Walk Test (RWT), a simple, noninvasive assessment that estimates aerobic fitness by measuring VO₂ max, the maximum amount of oxygen the body can absorb and use during intense exercise.
How to Take the Rockport Walk Test
- Walk one mile as fast as possible on a flat course. Record your time with a stopwatch and immediately note your heart rate using a heart rate monitor or smartphone.
- If you don’t have a heart rate monitor, take your pulse by gently pressing the tips of your index and middle fingers against the inside of your wrist or the side of your neck near your windpipe, counting the number of beats you feel in 15 seconds and multiplying by four.
- Enter your results into an online calculator along with your weight, age, and sex to compute your VO₂ max.
Interpreting Your Results
Use a VO₂ max chart to see how your number stacks up against other people in your age group. A higher VO₂ max typically means better physical fitness.
Improving Your Aerobic Capacity
If you are unhappy with your score, you can improve your aerobic capacity by doing cardio exercises or high-intensity interval training (HIIT), which involves short bursts of intense exercise with brief recovery periods.
The Significance of VO₂ max
VO₂ max doesn’t directly evaluate muscular strength or flexibility, but research has shown that it can strongly predict longevity. A 2018 study of 5,100 men found that those in the top 5% of VO₂ max lived almost five years longer than those in the bottom 5%.
Other Ways to Measure VO₂ max
There are alternative methods to measure VO₂ max, including the McArdle step test, the Astrand treadmill test, and the Cooper 1.5-mile walk-run test. These tests are more complex and require specialized equipment, but they can provide a more comprehensive assessment of cardiovascular fitness.
Conclusion
The Rockport Walk Test is a simple and accessible way to gauge your aerobic fitness and estimate your VO₂ max. By taking this test, you can gain a better understanding of your physical fitness and take steps to improve your overall health and well-being.
