Standards for Male, age 30 (30-39 age group). Jump distances are derived from the same linear scoring equation used on training results.

How to Perform the Broad Jump

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.

Use a two-foot takeoff—no stepping or running start allowed.
Generate power through a quick countermovement (dip) before jumping.
Land with both feet together and maintain your balance to avoid measurement penalties.
Keep your chest up and eyes forward throughout the jump.

1. Measurement + Preliminary Score

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), and m is set so the max estimated jump for your age range and gender maps to 100 points. The minimum is 0 inches. For male ages 30-39, the estimated max is 130 inches, so m = 0.771 and b = 0.

y = mx + b Chart (Example)

Example uses male 30-39 max = 130 inches. Score = (0.771 × inches) + 0.

Broad Jump (in)	Preliminary Score (y)
0	0
33	25
65	50
98	76
130	100

Linear Equation: y = 0.771x + 0

2. Final Score Calculation

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

The curve is highly favorable for new athletes, making lower scores much easier to achieve. Exceptional athletes will struggle to reach 100.

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

Curved Score: y = 100 × (x/100)^0.45
