Fourteen young healthy males participated in this study. Using ultrasound shear\u2010wave elastography, fascia elastic modulus was measured at rest (passive condition) and during submaximal isometric knee flexion efforts (active condition) with the hip at neutral position and the knee flexed at 0\u00b0, 45\u00b0, and 90\u00b0. Analysis of variance designs indicated that when the knee was passively extended from 90\u00b0 to 0\u00b0, shear modulus of the TLF, SMF, and STF increased significantly (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Similarly, active knee flexion contractions caused a significant increase in TLF, SMF, and STF shear modulus (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Compared to hamstring fascia, the TLF showed greater thickness but a lower shear modulus (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) while STF modulus was greater compared that to SMF during active contraction (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). These results indicate that exercising the hamstring muscles can remotely influence the stiffness of the fascia which surrounds the lumbar area.<\/jats:p>","DOI":"10.1111\/joa.13977","type":"journal-article","created":{"date-parts":[[2023,11,15]],"date-time":"2023-11-15T19:06:30Z","timestamp":1700075190000},"page":"438-447","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Is thoracolumbar fascia shear\u2010wave modulus affected by active and passive knee flexion?"],"prefix":"10.1111","volume":"244","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8179-6340","authenticated-orcid":false,"given":"Eleftherios","family":"Kellis","sequence":"first","affiliation":[{"name":"Laboratory of Neuromechanics, Department of Physical Education and Sport Sciences at Serres Aristotle University of Thessaloniki  Serres Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Afxentios","family":"Kekelekis","sequence":"additional","affiliation":[{"name":"Laboratory of Neuromechanics, Department of Physical Education and Sport Sciences at Serres Aristotle University of Thessaloniki  Serres Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleni E.","family":"Drakonaki","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Medical School University of Crete  Heraklion Crete Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,11,15]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmpt.2019.03.004"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469\u20107580.2008.01011.x"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2020.109930"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.13130702"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.23266"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2012.11.044"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fbioe.2021.810250"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11517\u2010021\u201002320\u20102"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010020\u201077123\u2010w"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/joa.12370"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.15557\/JoU.2012.0008"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2009.08.006"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0251939"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph182312356"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2011.09.004"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/JSM.0b013e31803220b3"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultrasmedbio.2010.02.013"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2008.03.006"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2014.12.004"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2015.09.038"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532\u2010950X.2014.12247.x"},{"key":"e_1_2_12_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelekin.2007.02.005"},{"key":"e_1_2_12_24_1","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2016.1172725"},{"key":"e_1_2_12_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2018.01.008"},{"key":"e_1_2_12_26_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13102\u2010022\u201000555\u20106"},{"key":"e_1_2_12_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelekin.2012.03.012"},{"key":"e_1_2_12_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2013.11.009"},{"key":"e_1_2_12_29_1","doi-asserted-by":"publisher","DOI":"10.1111\/joa.12464"},{"key":"e_1_2_12_30_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00421\u2010018\u20103967\u2010z"},{"key":"e_1_2_12_31_1","doi-asserted-by":"publisher","DOI":"10.1111\/sms.13732"},{"key":"e_1_2_12_32_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1360\u20108592(97)80010\u20101"},{"key":"e_1_2_12_33_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.math.2016.03.012"},{"key":"e_1_2_12_34_1","doi-asserted-by":"publisher","DOI":"10.1055\/a\u20100733\u20106957"},{"key":"e_1_2_12_35_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256\u2010019\u201003300\u20102"},{"key":"e_1_2_12_36_1","doi-asserted-by":"publisher","DOI":"10.1111\/joa.13505"},{"key":"e_1_2_12_37_1","doi-asserted-by":"crossref","unstructured":"Song P.
