The Challenge:

To monitor the frequency and magnitude of punches thrown by a boxer:

• What is the number of punches per minute?
• At what number of punches does the trainee become fatigued? (use this to monitor endurance improvements over time)
• With what force-in pounds, Newton's, or kilograms-is the trainee punching?

How it works:

This boxing setup measures the "weight" of the sandbag as measured by a digital load cell.  As the punches are thrown, the weight is perturbed.  The software counts the number and amount of the perturbation.  This allows the user to monitor his or her progress in rate of punches per minute, force of punches, and endurance over time via logging training session data with LoadVUE.

Solution:

By integrating one tilt resistant load cell into a punching bag apparatus, training data, such as frequency and intensity of punches, can easily be logged and analyzed to optimize and calibrate workouts.

• 1 iLoad Pro 100lb Load Cell
• 1 TX-300TA Adapter
• 2 Rod End Male RH (½ -20)
• LoadVUE Pro software

Total time to setup
• 10 minutes
