The girl's physical condition index would be 68.18. Therefore, its condition can be evaluated as High Average.

To know the physical condition index of a person it is necessary to take the Harvard Step Test, a physical test lasting 5 minutes with which you can measure the physical condition of a person from their beats per minute.

In this test, the person must climb a box about 50 cm high for 5 minutes, the idea is to have a rhythm of 1 step every 2 seconds. After completing the entire test, the person should sit down and take their pulse as follows:

  • Between minutes 1 and 1.5
  • Between minutes 2 and 2.5
  • Between minutes 3 and 3.5

After knowing these data, you can use the following formulas to establish your physical condition by relating the result to the rating table.

  • Simple Equation - Fitness Index = (100 x test duration in seconds) divided by (5.5 x pulse count between 1 and 1.5 minutes)
  • Complex equation - Fitness Index = (100 x test duration in seconds) divided by (2 x sum of heart beats in the recovery periods)

Harvard Step Test Ratings

  • Excellent = > 90
  • Good = 80 - 89
  • High Average = 65 - 79
  • Low Average = 55 - 64
  • Poor  = < 55

Fitness index = (100 x 300) divided by (5.5 x 80)

aptitude index = 68.18
