The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to compare the conventional and functional H:Q ratios calculated by PT and TW. Ninety\u2010three male professional soccer players from Brazilian first division teams performed isokinetic concentric and eccentric contractions of the quadriceps and the hamstrings at 60\u00b0\/s. Muscle strength balance was calculated using the conventional torque ratio (CTR) and conventional work ratio (CWR), functional torque ratio (FTR) and functional work ratio (FWR) were highly and moderately correlated between them (<jats:italic>r<\/jats:italic> = 0.83 and <jats:italic>r<\/jats:italic> = 0.73, respectively). The Wilcoxon statistical test revealed significant differences between CTR and CWR, as well as FTR and FWR (<jats:italic>p<\/jats:italic> &lt; 0.05). <jats:italic>T<\/jats:italic>\u2010test demonstrated significant differences in mean CTR\u2013CWR and FTR\u2013FWR, whereas Bland\u2013Altman plots showed non\u2010consistent bias. In addition, the chi\u2010square test demonstrated significant differences between players below the conventional reference values and functional reference values (<jats:italic>p<\/jats:italic> &lt; 0.001). In conclusion, TW ratios seem to provide distinct and additional information regarding the H:Q strength balance in professional soccer players. Moreover, taking into account that TW captures torque information throughout the entire range of motion, it is possible that TW ratios represent a more comprehensive assessment of muscle strength imbalance.<\/jats:p>","DOI":"10.1080\/17461391.2018.1495271","type":"journal-article","created":{"date-parts":[[2018,7,14]],"date-time":"2018-07-14T08:26:45Z","timestamp":1531556805000},"page":"1398-1404","update-policy":"https:\/\/doi.org\/10.1080\/tandf_crossmark_01","source":"Crossref","is-referenced-by-count":13,"title":["Alternative assessment of knee joint muscle balance of soccer players through total work\u2010based hamstring:\u00a0quadriceps ratios"],"prefix":"10.1002","volume":"18","author":[{"given":"Felipe","family":"Minozzo","sequence":"first","affiliation":[{"name":"Exercise Research Laboratory Physical Education School Federal University of Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro","family":"Lopez","sequence":"additional","affiliation":[{"name":"Exercise Research Laboratory Physical Education School Federal University of Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos Leonardo Figueiredo","family":"Machado","sequence":"additional","affiliation":[{"name":"Exercise Research Laboratory Physical Education School Federal University of Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eurico Nestor","family":"Wilhelm","sequence":"additional","affiliation":[{"name":"Department of Sports School of Physical Education Federal University of Pelotas Pelotas Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Grazioli","sequence":"additional","affiliation":[{"name":"Exercise Research Laboratory Physical Education School Federal University of Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronei Silveira","family":"Pinto","sequence":"additional","affiliation":[{"name":"Exercise Research Laboratory Physical Education School Federal University of Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,7,14]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465980260021201"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748\u20101716.1995.tb09927.x"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1055\/s\u20100032\u20101311586"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465020300020901"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jshs.2014.06.002"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/sms.12890"},{"key":"e_1_2_9_8_1","volume-title":"Isokinetics: Muscle testing, interpretation and clinical applications","author":"Dvir Z.","year":"2004"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports\u20102013\u2010092771"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports\u20102016\u2010096333"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546510395879"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.1999.29.5.275"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2014.942680"},{"issue":"3","key":"e_1_2_9_14_1","first-page":"364","article-title":"Lower limb strength in professional soccer players: Profile, asymmetry, and training age","volume":"9","author":"Fousekis K.","year":"2010","journal-title":"Journal of Sports Science & Medicine"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00705085"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546512470634"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsams.2007.04.009"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.11648\/j.ajss.20170501.11"},{"issue":"1","key":"e_1_2_9_19_1","first-page":"41","article-title":"Effect of hamstring\u2010emphasized resistance training on hamstring: Quadriceps strength ratios","volume":"21","author":"Holcomb W.
