The temporal profile of postactivation potentiation is related to strength level. J Strength Cond Res 28(3)706–715, 2014—The purpose of this investigation was to determine whether stronger individuals are able to express postactivation potentiation (PAP) earlier than weaker individuals during a vertical squat jump test. Eighteen junior elite rugby league players were divided into strong (relative 1 repetition maximum [1RM] back squat ≥2 × body mass) and weak (relative 1RM back squat <2.0 × body mass) groups. Each subject performed squat jumps before, 15 seconds, 3, 6, 9, and 12 minutes after a conditioning activity (CA) that contained 1 set of 3 back squats performed at 90% of 1RM. A force plate, which sampled at 1000 Hz, was used to determine the power output and height for each squat jump. Stronger individuals expressed PAP between 3 and 12 minutes post-CA, whereas their weaker counterparts displayed potentiation between 6 and 12 minutes post-CA. Moreover, the stronger group exhibited a significantly (p ≤ 0.05) higher PAP response than the weaker group at all post-CA squat jump tests. The stronger group displayed the greatest potentiation at 6 minutes post-CA, whereas the weaker group displayed the greatest potentiation response at 9 minutes following the CA. Based on these results, stronger individuals appear to be able to express PAP earlier after a CA than weaker individuals. Additionally, stronger individuals express significantly greater postactivation responses than weaker individuals. From a practical standpoint, strength and conditioning coaches should consider the athletesʼ strength levels when constructing postactivation complexes (CA + performance activity) as strength will dictate the time frame required between the conditioning and the performance activity.</description><identifier>ISSN: 1064-8011</identifier><identifier>EISSN: 1533-4287</identifier><identifier>DOI: 10.1519/JSC.0b013e3182a73ea3</identifier><identifier>PMID: 23965945</identifier><language>eng</language><publisher>United States: Copyright by the National Strength & Conditioning Association</publisher><subject>Adolescent ; Athletes ; Body mass index ; Coaches & managers ; Exercise Test ; Football ; Humans ; Movement - physiology ; Muscle Contraction - physiology ; Muscle Strength - physiology ; Muscle, Skeletal - physiology ; Rest - physiology ; Sports training ; Time Factors ; Young Adult</subject><ispartof>Journal of strength and conditioning research, 2014-03, Vol.28 (3), p.706-715</ispartof><rights>Copyright © 2014 by the National Strength & Conditioning Association.</rights><rights>Copyright Lippincott Williams & Wilkins Mar 2014</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c5143-cdfd5648c1bed8046d21247bee47097c379ae733a8fa29c8b91d7a5ed9a4fb383</citedby><cites>FETCH-LOGICAL-c5143-cdfd5648c1bed8046d21247bee47097c379ae733a8fa29c8b91d7a5ed9a4fb383</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27923,27924</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/23965945$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Seitz, Laurent B</creatorcontrib><creatorcontrib>de Villarreal, Eduardo S</creatorcontrib><creatorcontrib>Haff, G Gregory</creatorcontrib><title>The Temporal Profile of Postactivation Potentiation Is Related to Strength Level</title><title>Journal of strength and conditioning research</title><addtitle>J Strength Cond Res</addtitle><description>ABSTRACTSeitz, LB, de Villarreal, ES, and Haff, GG.
