Inaccurate standardized flexibility testing for tall individuals

πŸ’š healthsocial problemSingle report ●●●●● severity 2/5

A tall individual reports that standardized flexibility tests, such as the sit-and-reach test, are biased against people with longer limbs, failing to provide an objective measure of actual flexibility.

Who's affected: Tall individuals and possibly others with non-average limb proportions participating in fitness assessments.

What people do today

πŸ”§ Fix this

Ideas a builder, maker or community group could start on:

  1. Develop a normalized flexibility scoring app that adjusts reach metrics based on user limb-length measurements.
  2. Create a standardized set of joint-angle-based flexibility tests that use goniometers or smartphone camera tracking instead of reach distance.
  3. Publish a guide for fitness instructors on how to interpret reach-based tests by accounting for anthropometric variations.
