COMPARISON OF INTERRATER RELIABILILTY BETWEEN LOWER QUARTER Y BALANCE TEST AND THE SINGLE LEG SQUAT

COMPARISON OF INTERRATER RELIABILILTY BETWEEN LOWER QUARTER Y BALANCE TEST AND THE SINGLE LEG SQUAT B. R. Durre, S. Simmons, FACSM. Corban University, Salem, OR Both the Y Balance Test (YBT) and the Single Leg Squat (SLS) are pre-training functional test that are used to assess physical performance, both have been shown to be valid and reliable. However, it is unclear which is the most reliable between the two. PURPOSE: To test the interrater reliability YBT and the SLS, to examine which is a more reliable pre-training test. METHODS: The YBT and the SLS squat were performed by 16 (N=16, mean age M=19.313, SD ± 1.35; Freshman=8, Sophomore=5, Junior=1, Senior=2) male, NAIA collegiate baseball players. Each participant first performed the YBT which was scored simultaneously by 4 skilled raters. Directly following, each participant was recorded with a digital video camera performing the SLS. Each rater later viewed the video independently and scored the SLS. RESULTS: The SLS showed to have an acceptable (R2=.641; F(15, 45)=4.23, p=.00) interrater reliability between the 4 raters, whereas the YBT showed to have a good (R2=.895; F(15, 45)=9.62, p=.00). CONCLUSIONS: This study showed the YBT to be a reliable test; showing the YBT to have a higher interrater reliability than the SLS
