Which flexibility test is primarily used to evaluate shoulder mobility in TPI assessments?

The shoulder flexion test is the primary evaluation used to assess shoulder mobility in TPI assessments. This test specifically measures the range of motion available when raising the arms overhead and helps identify any limitations that could affect a golfer's swing mechanics. Adequate shoulder flexion is crucial for achieving the proper position at the top of the backswing and ensuring a full, unrestricted follow-through.

In the context of the TPI framework, understanding shoulder mobility contributes to overall body-swing connection, as limited range of motion can lead to compensations during the swing, potentially resulting in decreased performance and increased risk of injury. The shoulder flexion test, therefore, directly correlates to a golfer's ability to maintain proper form and effectiveness throughout their swing.
