ETThe Countermovement Jump (CMJ) is a commonly used test in sports science and strength and conditioning to assess lower-body power.
Here’s a breakdown of what it is and why we look at it:
⸻
🔍 What the CMJ Assesses
1. Lower-Body Power
The CMJ measures how effectively an athlete can generate force within a limited timeframe — a key component of a powerful golf swing.
2. Stretch–Shortening Cycle (SSC)
It evaluates how well the muscles and tendons store and release elastic energy.
3. Neuromuscular Function
The test reflects coordination and timing between muscles, showing how efficiently the nervous system is operating. This also means coaching, practice and familiarity with the test are important.
4. Fatigue and Recovery
When repeated over time, output and strategy metrics can indicate neuromuscular fatigue or recovery status, making it a useful monitoring tool.

⚙️ Why It’s Important
• Performance Indicator: Strong correlation with clubhead speed and drive distance - leading to lower scores.
• Simple and Reliable: Easy to perform and repeat, making it ideal for tracking progress over time.
