The results of the test can be calculated using the formulas:
Key Values – Power (Watts); Body mass (kilograms); Distance (meters); Time (seconds); Velocity (seconds); Acceleration (seconds); Force (Newtons).
How to: Calculate Peak Power Output (PPO)
- PPO = Body mass * Distance ² ÷ Time ³
From the six sprint times and PPOs, you can then calculate the following:
- Maximum power output (i.e. the highest value)
- Minimum power output (i.e. the lowest value)
- Average power output (i.e. the sum of all six values ÷ 6)
How to: Calculate Fatigue Index (FI)
This value represents the rate at which the power (W) declines in the participant’s performance. The lower the value the better the participant’s ability to maintain performance, and vice versa. Participants with high FI values may need to improve their anaerobic capacity and resistance to fatigue.
- FI = (Maximum power – Minimum power) ÷ Total time for the 6 sprints
How to: Calculate Relative Peak Power Output (RPP)
This unit of measure allows for a somewhat fair comparison between participants of various weights and sizes.
- RPP = peak power ÷ body weight
How to: Calculate Anaerobic Capacity (AC)
Anaerobic capacity is the total work completed during the test duration.
- AC = Sum of all six sprint PPOs
