Reliability of the Tuck Jump Assessment Using Standardized Rater Training.

PMID 33604146WHAT IT FOUND
Standardized online training did not make Tuck Jump individual flaw scores reliable.
Raters agreed moderately on total scores, but most individual jump flaws were scored inconsistently, so use total scores cautiously and avoid scoring each flaw alone.
Key findings
01The three raters showed good, moderate, and excellent reliability for their own repeated total scores.
02Interrater reliability for total scores was moderate in both sessions.
03Only 11 of 50 individual technique flaw reliability estimates were above the acceptable level.

What it does not show
The videos were from recreationally active college-aged adults, not the athlete population for whom the Tuck Jump Assessment was originally developed. Only three raters were included, so the reliability results may not apply to other professionals or experience levels. The study used videos from a previous project, not a new sample designed for reliability testing. Total scores could hide large differences in how individual flaws were scored, so they may not identify a specific risk pattern.
The easy way to misread this
Do not conclude that the modified Tuck Jump Assessment can reliably identify specific jump-landing flaws. The study found only 11 of 50 individual flaw reliability estimates acceptable, and most individual flaw agreement was slight, so total scores should not be broken down to guide treatment.
