A sequential averaging technique indicated a minimum of 11 jumps were required for stabilization of the kinetics. <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> The TJA exposes athletes to high magnitudes of vertical force. Based on the high variability of performance during early repetitions and the potential to miscategorize high-risk landing in female athletes, practitioners should consider scoring the TJA after 11 successive cycles and using kinetic profiling to support landing assessments.<\/jats:p>","DOI":"10.1123\/jsr.2021-0054","type":"journal-article","created":{"date-parts":[[2022,1,4]],"date-time":"2022-01-04T03:20:22Z","timestamp":1641266422000},"page":"524-528","source":"Crossref","is-referenced-by-count":5,"title":["Kinetics and Stabilization of the Tuck Jump Assessment"],"prefix":"10.1123","volume":"31","author":[{"given":"Lucy S.","family":"Kember","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rhodri S.","family":"Lloyd","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory D.","family":"Myer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabel S.","family":"Moore","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"21","key":"r1","series-title":"Br J Sports Med","first-page":"1543","article-title":"Fifty-five per cent return to competitive sport following anterior cruciate ligament reconstruction surgery: an updated systematic review and meta-analysis including aspects of physical functioning and contextual factors","volume":"48","author":"Ardern CL","year":"2014","unstructured":"Ardern CL, Taylor NF, Feller JA, Webster KE.
