The systematic review included peer-reviewed articles that incorporated interventions that included pre- and post-intervention physical fitness assessment. The search was performed in the SCOPUS, PubMed, and Web of Science databases between April and September 2022. PRISMA and the TESTEX checklist were used to select and assess the methodological quality of the studies. Twenty studies with 504 participants (428 males and 76 females) were included. Significant improvements were found in athletes\u2019 maximal dynamic and isometric strength, muscle power, flexibility, and balance. In addition, improvements in favor of the training groups in specific actions of judo, karate, fencing, and boxing were observed. In conclusion, interventions aimed at the development of muscle strength in OCS, specifically in judo, boxing, karate, wrestling, and fencing, proved to be beneficial at a physical fitness level, resulting in significant increases in favor of the training groups with OCS, which could be used by trainers and coaches to improve the physical performance of athletes.<\/jats:p>","DOI":"10.3390\/ijerph20043516","type":"journal-article","created":{"date-parts":[[2023,2,17]],"date-time":"2023-02-17T01:59:24Z","timestamp":1676599164000},"page":"3516","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Effects of Strength Training on Physical Fitness of Olympic Combat Sports Athletes: A Systematic Review"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2172-867X","authenticated-orcid":false,"given":"Izham","family":"Cid-Calfucura","sequence":"first","affiliation":[{"name":"Escuela de Ciencias del Deporte y Actividad F\u00edsica, Facultad de Salud, Universidad Santo Tom\u00e1s, UST, Santiago 8370003, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5219-5896","authenticated-orcid":false,"given":"Tom\u00e1s","family":"Herrera-Valenzuela","sequence":"additional","affiliation":[{"name":"Sciences of Physical Activity, Sports and Health School, Faculty of Medical Sciences, Universidad de Santiago de Chile (USACH), Santiago 9170022, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0769-8398","authenticated-orcid":false,"given":"Emerson","family":"Franchini","sequence":"additional","affiliation":[{"name":"Martial Arts and Combat Sports Research Group, Sport Department, School of Physical Education and Sport, University of S\u00e3o Paulo, Sao Paulo 05594-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6565-1654","authenticated-orcid":false,"given":"Coral","family":"Falco","sequence":"additional","affiliation":[{"name":"Department of Sport, Food and Natural Sciences, Western Norway University of Applied Sciences, 5020 Bergen, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Alvial-Moscoso","sequence":"additional","affiliation":[{"name":"Escuela de Ciencias del Deporte y Actividad F\u00edsica, Facultad de Salud, Universidad Santo Tom\u00e1s, UST, Santiago 8370003, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Pardo-Tamayo","sequence":"additional","affiliation":[{"name":"Escuela de Ciencias del Deporte y Actividad F\u00edsica, Facultad de Salud, Universidad Santo Tom\u00e1s, UST, Santiago 8370003, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Zapata-Huenull\u00e1n","sequence":"additional","affiliation":[{"name":"Escuela de Ciencias del Deporte y Actividad F\u00edsica, Facultad de Salud, Universidad Santo Tom\u00e1s, UST, Santiago 8370003, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2406-9622","authenticated-orcid":false,"given":"Alex","family":"Ojeda-Aravena","sequence":"additional","affiliation":[{"name":"IRyS Group, Physical Education School, Pontificia Universidad Cat\u00f3lica de Valpara\u00edso, Valpara\u00edso 2581967, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3948-8280","authenticated-orcid":false,"given":"Pablo","family":"Vald\u00e9s-Badilla","sequence":"additional","affiliation":[{"name":"Department of Physical Activity Sciences, Faculty of Education Sciences, Universidad Cat\u00f3lica del Maule, Talca 3530000, Chile"},{"name":"Sports Coach Career, School of Education, Universidad Vi\u00f1a del Mar, Vi\u00f1a del Mar 2520000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"ref_1","unstructured":"(2022, July 10).
