Calculate Fatigue Index Percentage in Hand Grip Test
The hand grip test is a crucial tool for assessing muscle strength and endurance. Calculating the fatigue index percentage helps understand how quickly your grip strength declines under sustained effort. This calculator simplifies that process.
- Enter the maximum force you can apply with your hand (in Newtons).
- Enter the force you can maintain for the given time (in Newtons).
- Enter the time you maintained the force (in seconds).
- Click ‘Calculate’ to see your fatigue index percentage and a visual representation.
The fatigue index percentage (FIP) is calculated using the formula:
FIP = [(Max Force – Maintained Force) / Max Force] * 100
The chart shows the decline in force over time.
| Subject | Max Force (N) | Maintained Force (N) | Time (s) | FIP (%) |
|---|
- Regularly test and track your fatigue index to monitor progress.
- Incorporate grip strength training into your workout routine.
- Consider using ergonomic tools to reduce hand fatigue.
What is a good fatigue index percentage?
A lower fatigue index percentage indicates better endurance. Aim for less than 30%.
