The data sources utilized were Web of Science, Scopus, SPORTDiscus, and PubMed. The study eligibility criteria were: (i) parallel studies (SSG-based programs vs. running-based HIIT) conducted in soccer players with no restrictions on age, sex, or competitive level; (ii) isolated intervention programs (i.e., only SSG vs. only running-based HIIT as individual forms) with no restrictions on duration; (iii) a pre\u2013post outcome for RSA; (iv) original, full-text, peer-reviewed articles written in English. An electronic search yielded 513 articles, four of which were included in the present study. There was no significant difference between the effects of SSG-based and HIIT-based training interventions on RSA (effect size (ES) = 0.30; p = 0.181). The within-group analysis revealed no significant effect of SSG-based training interventions (ES = \u22120.23; p = 0.697) or HIIT-based training interventions (ES = 0.08; p = 0.899) on RSA. The meta-comparison revealed that neither SSGs nor HIIT-based interventions were effective in improving RSA in soccer players, and no differences were found between the two types of training. This suggests that complementary training may be performed to improve the effects of SSGs and HIIT. It also suggests that different forms of HIIT can be used because of the range of opportunities that such training affords.<\/jats:p>","DOI":"10.3390\/ijerph18052781","type":"journal-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T12:08:01Z","timestamp":1615291681000},"page":"2781","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["A Meta-Analytical Comparison of the Effects of Small-Sided Games vs. Running-Based High-Intensity Interval Training on Soccer Players\u2019 Repeated-Sprint Ability"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9813-2842","authenticated-orcid":false,"given":"Filipe Manuel","family":"Clemente","sequence":"first","affiliation":[{"name":"Escola Superior Desporto e Lazer, Instituto Polit\u00e9cnico de Viana do Castelo Rua Escola Industrial e Comercial de Nun\u2019\u00c1lvares, 4900-347 Viana do Castelo, Portugal"},{"name":"Instituto de Telecomunica\u00e7\u00f5es, Delega\u00e7\u00e3o da Covilh\u00e3, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2035-3279","authenticated-orcid":false,"given":"Rodrigo","family":"Ramirez-Campillo","sequence":"additional","affiliation":[{"name":"Quality of Life and Wellness Research Group, Human Performance Laboratory, Department of Physical Activity Sciences, Universidad de Los Lagos, Osorno 5290000, Chile"},{"name":"Centro de Investigaci\u00f3n en Fisiolog\u00eda del Ejercicio, Facultad de Ciencias, Universidad Mayor, Santiago 7500000, Chile"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2038-393X","authenticated-orcid":false,"given":"Jos\u00e9","family":"Afonso","sequence":"additional","affiliation":[{"name":"Centre for Research, Education, Innovation and Intervention in Sport, Faculty of Sport of the University of Porto, 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8681-0642","authenticated-orcid":false,"given":"Hugo","family":"Sarmento","sequence":"additional","affiliation":[{"name":"Research Unit for Sport and Physical Activity, Faculty of Sport Sciences and Physical Education, University of Coimbra, Coimbra, 3004-531 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6436-6306","authenticated-orcid":false,"given":"Thomas","family":"Rosemann","sequence":"additional","affiliation":[{"name":"Institute of Primary Care, University of Zurich, 8091 Zurich, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2412-9103","authenticated-orcid":false,"given":"Beat","family":"Knechtle","sequence":"additional","affiliation":[{"name":"Institute of Primary Care, University of Zurich, 8091 Zurich, Switzerland"},{"name":"Medbase St. Gallen Am Vadianplatz, 9001 St. Gallen, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"154","DOI":"10.1097\/JES.0b013e318292f3ec","article-title":"How small-sided and conditioned games enhance acquisition of movement and decision-making skills","volume":"41","author":"Davids","year":"2013","journal-title":"Exerc.
