Rockport walk test · One-mile walk test
Purpose
Use this test to estimate aerobic fitness from a walk. Your client walks one mile as fast as they can, and you record the time and the heart rate at the finish.
Kline and colleagues built the equation from 343 healthy adults aged 30 to 69, whose VO2max was also measured on a treadmill.
Procedure
- Preparation
- Use a flat, measured course such as a running track. One mile is 1,609 m. Your client wears a heart rate monitor. Weigh your client before the walk.
- Equipment
- A measured one-mile course, a heart rate monitor and a stopwatch
Walk one mile
Start the stopwatch. Your client walks one mile as fast as they can, without running.
Stop the time
Stop the stopwatch as your client crosses the finish.
Read the heart rate
Read the heart rate at the finish, at the end of the last quarter mile.
Scoring
The score is the time for one mile, in minutes and seconds. The VO2max estimate also uses the heart rate at the finish, body weight, age and sex.
Formulas
- Estimated VO2max (L/min)
- 6.9652 + 0.0091 × weight (lb) − 0.0257 × age + 0.5955 × sex − 0.2240 × time (min) − 0.0115 × heart rate
- Per kilogram (ml/kg/min)
- VO2max (L/min) × 1000 ÷ weight (kg)
Sex is 1 for men and 0 for women. The calculator gives no estimate outside ages 30 to 69, the ages of the study.
Interpretation
Compare walk times on the same course. The calculator shows the time and the estimate without a label.
