Power Testing: Vertical Jump Test
Jun 27, 2023The Vertical Jump test is a common test used to measure an individual's lower body power, specifically their ability to jump vertically. The test is often used in sports such as basketball, volleyball, and track and field, as well as in fitness and rehabilitation settings.
To perform the Vertical Jump test, follow these general steps:
- Stand facing a wall or vertical measuring device that is high enough to capture the client's highest jump height.
- Calibrate by having the client reach up and touch the wall or measuring device with their fingertips, marking their standing reach height.
- Once set, have the client set up with their feet shoulder-width apart and hands either on their hips or by their sides.
- Queue the client to jump straight up as high as possible, reaching upward with their arms.
- Land back on the ground in the starting position.
- Measure and record the distance between the client’s standing reach height and the highest point they reached during the jump.
- Repeat the jump two more times, recording the highest jump height of the three jumps.
- Rest for about 30 seconds between each jump to allow for optimal recovery.
It's important to ensure proper jumping technique, including using the arms to generate upward momentum and bending the knees to gather energy before jumping. Additionally, the individual should not take any steps before jumping or use any additional equipment or aids (such as a running start or weights).
Here are some general guidelines for normative data of vertical jump height:
- Average jump height for untrained males: 16-20 inches (40-50 cm)
- Average jump height for untrained females: 12-16 inches (30-40 cm)
- Average jump height for trained males: 24-28 inches (60-70 cm)
- Average jump height for trained females: 20-24 inches (50-60 cm)
Note that these values are approximate and can vary depending on the specific population being tested and the testing protocol used. It's important to consult appropriate references for specific normative data based on age, gender, and fitness level.
