Step Test Fitness Score Calculator

How it is calculated

The tool needs the time you kept stepping, D in seconds, and three recovery pulse counts P1, P2, P3. The long-form Physical Efficiency Index is PEI = 100 × D / (2 × (P1 + P2 + P3)). It also gives the short form, which uses only the first count: PEI = 100 × D / (5.5 × P1). Both are shown to one decimal place. In the standard protocol each pulse count is the number of beats in 30 seconds, taken at about 1, 2 and 3 minutes after you stop, and a full test lasts 5 minutes (300 seconds). Duration must be above 0 and at most 300 seconds, and each count must be between 10 and 125 beats (20 to 250 per minute); anything outside shows no result. A lower recovery pulse gives a higher index. The tool gives the index only, with no rating bands.

Common mistakes

• Entering beats per minute instead of the count for the 30-second window. A value such as 150 is above the 125-beat limit and shows no result, while a resting-rate bpm such as 72 would be accepted and make the index about half what it should be.
• Entering the duration in minutes. The field is seconds: a 5-minute test is 300, and typing 5 gives a meaningless score of about 1.
• Entering a duration above 300 seconds. The standard test stops at 5 minutes, and longer values show no result.
• Entering the planned test time when you stopped early. Use the seconds you actually stepped, since the index is proportional to it.
• Typing the same pulse count three times, or only one of them. All three counts are required, and the short form uses only the first one.
• Comparing a score to another person's from a different bench height or stepping rate. The index assumes the same standardised test conditions.
