Performance, Test-retest Reliability, and Measurement Error of the Upper Limb Seated Shot Put Test According to Different Positions of Execution.

PMID 37425121WHAT IT FOUND
The floor version of the seated shot put test is more consistent than the chair version.
Women threw further from the chair, but the chair test showed measurement error on the dominant arm. Use the floor test for tracking shoulder power in healthy overhead athletes.
Key findings
01Women threw significantly further when performing the test seated on a chair compared to the floor, while men showed no difference between positions.
02The floor test showed excellent reliability for both arms, whereas the chair test had moderate reliability for the non-dominant arm and systematic error for the dominant arm.
03Scores between the floor and chair tests were strongly correlated for most groups, except for the dominant arm in women aged 26 to 40.

What it does not show
The study only included healthy athletes, so the reliability and error margins may not apply to patients currently experiencing shoulder pain or dysfunction. The sample was limited to handball players, so results might differ for other overhead sports like baseball or volleyball. The reliability analysis used a small subset of only 10 participants. All testing occurred during the competitive season, so training fatigue may have influenced the scores.

The easy way to misread this
Do not assume the floor and chair tests are interchangeable for all patients. While the scores correlate well for men and younger women, the chair test produced systematically different results for women and showed measurement error on the dominant arm. Switching between positions mid-rehabilitation could look like a change in performance when it is actually a change in testing method.
