It causes loss in skeletal muscle function and soreness. As there are no firm preventive strategies, we aimed to evaluate the preventive efficacy of nonthermal 448-kHz capacitive resistive monopolar radiofrequency (CRMRF) therapy after eccentric bouts of EIMD response in knee flexors. <jats:italic><jats:bold>Design<\/jats:bold>:<\/jats:italic> Twenty-nine healthy males (age: 25.2 [4.6]\u00a0y) were randomized in control group (CG; n\u2009=\u200915) and experimental group (EG; n\u2009=\u200914) where EG followed 5 daily 448-kHz CRMRF therapies. All assessments were performed at baseline and post EIMD (EIMD\u2009+\u20091, EIMD\u2009+\u20092, EIMD\u2009+\u20095, and EIMD\u2009+\u20099\u00a0d). We measured tensiomyography of biceps femoris and semitendinosus to calculate contraction time, the maximal displacement and the radial velocity of contraction, unilateral isometric knee flexors maximal voluntary contraction torque, and rate of torque development in first 100\u00a0milliseconds. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Maximal voluntary contraction torque and rate of torque development in first 100\u00a0milliseconds decreased more in CG than in EG and recovered only in EG.\u00a0Biceps femoris contraction time increased only in CG (without recovery), whereas in semitendinosus contraction time increased in EG (only at EIMD\u2009+\u20091) and in CG (without recovery). In both muscles, tensiomyographic maximal displacement decreased in EG (in EIMD\u2009+\u20091 and EIMD\u2009+\u20092) and in CG (without recovery). Furthermore, in both muscles, radial velocity of contraction decreased in EG (from EIMD\u2009+\u20091 until EIMD\u2009+\u20095) and in CG (without recovery). <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> The study shows beneficial effect of CRMRF therapy after inducing EIMD in skeletal muscle strength and contractile parameters in knee flexors.<\/jats:p>","DOI":"10.1123\/jsr.2022-0162","type":"journal-article","created":{"date-parts":[[2023,5,16]],"date-time":"2023-05-16T15:32:05Z","timestamp":1684251125000},"page":"687-694","source":"Crossref","is-referenced-by-count":3,"title":["Effectiveness of 448-kHz Capacitive Resistive Monopolar Radiofrequency Therapy After Eccentric Exercise-Induced Muscle Damage to Restore Muscle Strength and Contractile Parameters"],"prefix":"10.1123","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1565-7833","authenticated-orcid":true,"given":"Bo\u0161tjan","family":"\u0160imuni\u010d","sequence":"first","affiliation":[{"name":"Science and Research Centre Koper, Institute for Kinesiology Research, Koper, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"Doles","sequence":"additional","affiliation":[{"name":"Science and Research Centre Koper, Institute for Kinesiology Research, Koper, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robi","family":"Kelc","sequence":"additional","affiliation":[{"name":"Medical Faculty, Institute for Sports Medicine, University of Maribor, Maribor, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrej","family":"\u0160vent","sequence":"additional","affiliation":[{"name":"Intact Ltd, Ljubljana, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"key":"r1","series-title":"Front Physiol","article-title":"Skeletal muscle remodeling in response to eccentric vs. concentric loading: morphological, molecular, and metabolic adaptations","volume":"8","author":"Franchi MV","year":"2017","unstructured":"Franchi MV, Reeves ND, Narici MV.
