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:

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.

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.

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. 

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.

If the strength score has decreased by 10% or more, the app will automatically modify your arm care to a recovery-based program that reduces training loads & volume. 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 for the arm throughout a pitcher’s season (McHugh, 2016).
