Use the responsive calculator grid below. Large screens show three columns, smaller screens show two, and phones stack fields into one column.
Example Data Table
| Athlete | Sport | Mass (kg) | 30 m Time (s) | Jump (cm) | Estimated 1RM (kg) | Peak Power (W) | Score | Tier |
|---|---|---|---|---|---|---|---|---|
| Ava Chen | Volleyball | 78.00 | 4.05 | 56.00 | 175.00 | 7,740.00 | 78.74 | High Performance |
| Malik Foster | Rugby | 92.00 | 4.45 | 48.00 | 204.00 | 7,995.00 | 70.88 | High Performance |
| Sofia Grant | Basketball | 68.00 | 3.92 | 61.00 | 144.00 | 7,520.00 | 82.45 | Advanced Power |
These rows illustrate how the calculator responds to different speed, force, jump, and fatigue profiles.
Formula Used
The Athlete Power Score combines sprint, jump, strength, force, and fatigue into one weighted output. Each component is normalized to a 0–100 scale before the final score is adjusted by fatigue.
| Movement Speed | Sprint Distance ÷ Sprint Time |
|---|---|
| Estimated 1RM | Strength Load × (1 + Reps ÷ 30) |
| Relative Strength | Estimated 1RM ÷ Body Mass |
| Peak Mechanical Power | Peak Force × Peak Velocity |
| Jump Power Estimate | (60.7 × Vertical Jump cm) + (45.3 × Body Mass kg) − 2055 |
| Base Score | (0.22 × Speed Index) + (0.18 × Jump Index) + (0.22 × Strength Index) + (0.28 × Power Index) + (0.10 × RSI Index) |
| Fatigue Modifier | 1 − (Fatigue % ÷ 200), capped from 0.60 to 1.00 |
| Final Athlete Power Score | Base Score × Fatigue Modifier |
Reference caps used for normalization are 9.5 m/s speed, 75 cm jump, 2.5 relative strength, 70 W/kg relative power, and 3.0 RSI.

FAQs
1. What does the Athlete Power Score measure?
It estimates usable athletic power by blending speed, jump ability, strength, mechanical power, and fatigue. The final number helps compare sessions with a consistent scoring method.
2. Which athletes can use this calculator?
It works best for field, court, combat, and team sport athletes. Coaches can also adapt it for general performance testing in schools, academies, and private training settings.
3. Why is fatigue included in the score?
Fatigue changes how much power an athlete can actually express on a given day. Including it makes the score more useful for programming and readiness decisions.
4. Is the score comparable across different sports?
Yes, but it is best used within similar groups first. Sport demands differ, so the score should support coaching judgment rather than replace context.
5. Can I use lab values or field test values?
Yes. The calculator accepts either, as long as your testing method stays consistent. Consistency matters more than using the most advanced device every time.
6. How often should I retest athletes?
Most teams can retest every two to four weeks. High-performance environments may track some inputs weekly if test fatigue and scheduling are managed well.
7. What is considered a good score?
Scores above 80 suggest strong power expression, while scores above 90 indicate elite output in this model. Always compare against your own roster history and sport standards.
8. Does this replace a coach or sports scientist?
No. It is a decision-support tool. It helps organize performance data, but training choices should still consider skill, injury status, schedule, and athlete feedback.
