Why it matters

The shoulder must be both strong and stable to transfer force effectively and to protect the surrounding tissue from damage. 

Research shows that preseason scaption weakness is a good predictor of in-season injury risk and that players tend to lose scaption strength throughout the season when exposed to heavy workloads.

Analyzing Scaption

Strength

There are three ways that the app compares scaption strength. Scaption strength indicates the strength of muscles that raise the arm up.

1. Percentile

Percentile compares your scaption strength to other players your age. If you are in the lower third for players your age, you know that this is an area that you need to improve. A solid goal would be to raise your strength to the 80th percentile or better. That means that your strength is better than 80% of the population.

2. Symmetry

Symmetry compares the scaption strength of your throwing side to your non-throwing side, in which most players are stronger on their throwing arm.

In some cases, pitchers can show greater non-throwing side strength in their shoulder. When this is noticed, our customized training program becomes modified to correct imbalance.

In some cases, pitchers can show greater non-throwing side strength in their shoulder. When this is noticed, our customized training program becomes modified to correct imbalance.

3. Trend

Trend analyzes how your strength has changed compared to previous tests. It’s normal for a player’s strength to fluctuate throughout the season, but these changes should be monitored and addressed.

Decreased strength by more than 10% will automatically modify your arm care and provide a recovery-based program of reduced training load. Along with symmetry, the trend score is an excellent marker to identify arm fatigue.

Summary of Research
  • A 5-year study of Major League Baseball Players found that preseason scaption weakness was a good predictor of in-season injuries that required surgery (Byram, 2010).
  •  

  • McHugh et al. showed a 13% drop in supraspinatus strength, which is an important stabilizer and elevator of the throwing arm throughout a pitcher’s season.

 

TAKE HOME MESSAGE: Scaption strength needs to be consistent, so that release point is maintained all season long and that the shoulder is stable during deceleration. Use the ArmCare app to minimize scaption strength loss.
