Fifteen male Division III athletes participated voluntarily. Eleven synchronized cameras and two force platforms were used to collect data. One-way repeated-measures analysis of variance tests were used to examine the differences between drop heights. The maximum hip, knee and ankle power absorption during 125%MVJH and 150%MVJH were greater than those during 75%MVJH. The impulse during landing at 100%MVJH, 125%MVJH and 150%MVJH were greater than 75%MVJH. The vertical ground reaction force during 150%MVJH was greater than 50%MVJH, 75%MVJH and 100%MVJH. Drop height below 75%MVJH had the most merits for increasing joint power output while having a lower impact force, impulse and joint power absorption. Drop height of 150%MVJH may not be desirable as a high-intensity stimulus due to the much greater impact force, increasing the risk of injury, without increasing jump height performance.<\/jats:p>","DOI":"10.1055\/s-0043-114011","type":"journal-article","created":{"date-parts":[[2017,9,12]],"date-time":"2017-09-12T10:57:58Z","timestamp":1505213878000},"page":"842-846","source":"Crossref","is-referenced-by-count":20,"title":["Optimum Drop Jump Height in Division III Athletes: Under 75% of Vertical Jump Height"],"prefix":"10.1055","volume":"38","author":[{"given":"Hsien-Te","family":"Peng","sequence":"additional","affiliation":[{"name":"Physical Education, Chinese Culture University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cong","family":"Khuat","sequence":"additional","affiliation":[{"name":"Science Department, Hanoi University of Sports and Physical education, Hanoi, Viet Nam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Kernozek","sequence":"additional","affiliation":[{"name":"Health Professions, University of Wisconsin-La Crosse, La Crosse, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Wallace","sequence":"additional","affiliation":[{"name":"Kinesiology and Athletic Training, University of Wisconsin-Oshkosh, Oshkosh, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin-Liang","family":"Lo","sequence":"additional","affiliation":[{"name":"Physical Education, Chinese Culture University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen-Yi","family":"Song","sequence":"additional","affiliation":[{"name":"Physical Therapy, National Taiwan University, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2017,9,11]]},"container-title":["International Journal of Sports Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0043-114011.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,12,19]],"date-time":"2017-12-19T12:52:34Z","timestamp":1513687954000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0043-114011"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,9,11]]},"references-count":0,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2017,10,6]]},"published-print":{"date-parts":[[2017,10]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0043-114011","relation":{},"ISSN":["0172-4622","1439-3964"],"issn-type":[{"value":"0172-4622","type":"print"},{"value":"1439-3964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,9,11]]}}}
