Is There a Vertical Jump Test?
The vertical jump test measures lower-limb explosive power — the ability to generate maximal force in the shortest time. It is one of the most commonly used tests for assessing athletes' power.
The test is especially important for basketball, volleyball, football and track and field athletes. A higher jump correlates with better sports results in these sports.
There is data that vertical jump is one of the most reliable indicators of lower-limb power (r=0.85-0.95 with sports results).
📏 Testing Methods
There are several main methods for measuring vertical jump:
| Method | Description | Accuracy | Price |
|---|---|---|---|
| Sargent Test | Chalk on fingers — mark on wall while standing and jumping | ±3-5 cm | Very low |
| Vertec System | Adjustable plastic vanes — the athlete reaches the highest vane | ±2-3 cm | Medium |
| Force Platform | Measures force impulse — calculates jump height from flight time | ±0.5 cm | Large |
| Optical system (Optojump) | Infrared barriers measure flight and contact time | ±0.1 cm | Very high |
| Mobile apps | Video analysis using a smartphone | ±2-5 cm | Low |
📋 Testing Protocol
Standardized vertical jump testing protocol:
- Warm-Up: 10 min light jogging + dynamic stretching + 3-5 light jumps.
- Starting position: stand upright, feet shoulder-width apart, arms at sides.
- Preparation: quick squat (countermovement) and arm swing upward.
- Jump: maximal explosive vertical jump.
- Arms extended: at the highest point, the tester records the hand/observation point.
- 3-5 attempts with 1-2 min rest between them.
