Stand behind the starting line with feet shoulder-width apart, toes just behind the line. Use a quick arm swing and knee bend to generate forward momentum, then explode forward with both feet leaving the ground simultaneously. Swing your arms forward during the jump to maximize distance. Land on both feet simultaneously, maintaining balance without falling backward.
Your broad jump is measured in inches from the takeoff line to the nearest point of contact on landing. A preliminary score is generated with the linear equation y = mx + b, where x is your jump distance (inches), b is 0, and m is set so the max estimated jump for your age range and gender maps to 100 points. The minimum is 0 inches. Example: For a male ages 20–29, the estimated max is 144 inches, so m = 100 / 144 = 0.694.
| Broad Jump (in) | Preliminary Score (y) |
|---|---|
| 0 | 0.0 |
| 50 | 34.7 |
| 100 | 69.4 |
| 130 | 90.2 |
| 144 | 100.0 |
The final score uses a curved calculation that heavily favors new athletes and makes reaching 100 extremely challenging even for exceptional performers. The curve is designed to provide significant scoring boosts at lower performance levels, encouraging participation and improvement. However, achieving the maximum score of 100 requires near-perfect performance across multiple attempts. The formula applies a power curve: Final Score = 100 × (Preliminary Score / 100)^0.45
| Preliminary Score | Final Score |
|---|---|
| 0 | 0.0 |
| 20 | 48.5 |
| 40 | 66.2 |
| 60 | 79.5 |
| 80 | 90.4 |
| 90 | 95.4 |
| 95 | 97.7 |
| 98 | 99.1 |
| 100 | 100.0 |
