Effects of video filming angle on throwing form instruction: enhancing recognition of the "elbow dropped" position.
Kentaro Kawai
PMID 41328277WHAT IT FOUND
For young baseball players with an "elbow dropped" fault, stick figure animations were clearer than actual videos for recognizing the error.
Filming from the front or dorsal angles provided the highest clarity, helping players identify the fault that was previously invisible to them.
Key findings
01Participants found it significantly easier to recognize the "elbow dropped" position in stick figure animations compared to actual video recordings of themselves.
02Among the four filming angles tested for stick figures, the front and dorsal views were rated as the most clear and comprehensible, significantly better than the ventral view.

What it does not show
The study only included elementary and junior high school players, so the findings may not apply to high school, collegiate, or elite-level athletes. The assessment focused solely on recognizing the "elbow dropped" fault and did not evaluate how well players understood other parts of their throwing mechanics, such as trunk or lower limb movement. The study measured whether players could recognize the fault, but did not test whether this improved recognition actually led to better throwing form or reduced pain.

The easy way to misread this
Do not assume that using this video feedback method will automatically correct the throwing fault or reduce injury risk. The study only confirmed that players could recognize the error more easily; it did not measure whether this recognition led to improved mechanics or clinical outcomes.
