BENET-VIGO, A et al. Detection of neuromuscular deficits through jumping pattern analysis in adolescent athletes. CPD [online]. 2021, vol.21, n.3, pp.224-232.  Epub May 23, 2022. ISSN 1989-5879.

The main objective of the present study was to analyze the performance of the jump and landing technique in adolescent team sports athletes through the modified version of the Tuck Jump Assessment, (TJA). As a secondary objective, the results obtained were compared, according to sex. Each outcome measure of the tool was scored through video analysis of the test of the 75 participants included in the study. The main outcome measures were the total score of TJA and each of the ten items: Knee valgus at landing (1), thighs do not reach parallel (2), thighs not equal side-to-side (3), foot placement not shoulder width apart (4), foot placement not parallel (5), foot contact timing not equal (6), excessive landing contact noise (7), pause between jumps (8), technique declines prior to ten seconds (9), and does not land in same footprint (10). The variables contemplated were the global score of the TJA and the ten criteria of the instrument. The average values of the global score of the modified version of the TJA were 8.85±2.31 in the total sample (8.85±2.63 men vs. 8.86±2.14 women). The results of the gender comparison indicated significant differences in item 1(χ2=10.288; p< 0.01), item 2 (χ2=20.788; p<0.01), item 4 (χ2=22.587; p<0.01) and item 10 (χ2=8.883; p< 0.01). Consequently, the analysis of the jump and landing pattern makes it possible to identify neuromuscular and biomechanical alterations of the jump-landing pattern.
