Why Measuring Arm Deceleration Strength Changes Everything
The LiVE ARM Difference:
- Beyond Pitch Counts
While traditional pitch counts are valuable, they tell only part of the story, workload. LiVE ARM measures what really matters: the strength of the arm’s decelerating muscles – the system that needs to absorb up to 108% of your body weight with every pitch.
- Isometric Testing – Safe & Reliable The patented LiVE ARM device is:
- Fast – Individualized custom set up takes 5 minutes. Each subsequent test takes just 2 minutes.
- Portable and durable for any setting
- Reliable
- Safe
- Shareable, an entire team, facility or league can benefit from 1 device
- What We Measure: LiVE ARM precisely measures the collective strength of critical muscle groups:
- Posterior rotator cuff muscles (supraspinatus, infraspinatus, teres minor)
- Scapula stabilizing muscles
- All key arm decelerating muscles in their functional position
- Validated Results: Studies with high school, college and professional pitchers have shown:
- 95%+ reliability in measurements
- Strong correlation between persistent fatigue and injury
- Clear identification of at-risk pitchers who showed no other symptoms
- No subjective examiner dependency – the data is clear and objective
- Personalized Baselines: LiVE ARM establishes each pitcher’s unique baseline strength profile and tracks changes over time to identify fatigue accounting for:
- Individual development stages
- Day-to-day variables (nutrition, hydration, sleep)
- Workload, Seasonal training effects
- Recovery patterns
- What the LiVE ARM tells us:
- When a player can intensify training or gain velocity without injury
- A players objective tolerance to fatigue
- When a player needs recovery time or is hiding an arm issue
- A player’s compliance with an exercise program
- What the LiVE ARM could teach us:
- Which pitching mechanics are more or less prone to causing fatigue of the shoulder decelerating muscles
- Which exercise program best targets the decelerating muscles
The Missing Piece in Pitcher Protection
“LiVE ARM measures what really matters: the strength of the arm’s decelerating muscles – the system that needs to absorb up to 108% of your body weight with every pitch.”
ACCURATE DATA FOR EACH AND EVERY INDIVIDUAL PITCHER:
Every athlete’s physiology differs which is why using “workload” estimates like pitch-count prove to be ineffective over and over again. The LiVEARM device is unique because it sets a baseline for each individual pitcher that uses the device.
Research Spotlight:
It has been shown that pitching with arm fatigue makes a pitcher 36 times more likely to have an arm injury requiring surgery. LiVE ARM is the first device to objectively measure arm fatigue.
