Question

Calculate the Physical Fitness Index using short formula for a 12 year old boy having completed Harvard step test for a duration of 3 minute and a pulse rate of 54 beats for 1 to 1.5 minute.

Answer 1

Given:

Age of the boy = 12 years

Duration of exercise = 3 minutes = 180 seconds

Pulse rate (1 to 1.5 minutes) = 54 beats

\[\text{Physical Fitness Index} = \frac{(100 \times \text{test duration in seconds})}{(5.5 \times \text{Pulse Count between 1 and 1.5 minutes})}\]

\[ \text{PFI}=\frac{100\times180}{5.5\times54} \]

\[ =\frac{18000}{297} \]

\[ = {60.61} \]

The Physical Fitness Index (PFI) of the 12-year-old boy is 60.61, which falls under the Average fitness category according to the commonly used Harvard Step Test rating scale.
