The studies\n                    included in this review followed the PICOS criteria: (i) healthy soccer players;\n                    (ii) interventions based on SSGs; (iii) comparators exposed to only HIIT or\n                    combined SSGs+HIIT; (iv) endurance performance variables. Studies were\n                    searched for in the following databases: (i) PubMed; (ii) Scopus; (iii)\n                    SPORTDiscus; (iv) Web of Science. After conducting an initial database search\n                    that retrieved a total of 5,389 records, a thorough screening process resulted\n                    in the inclusion of 20 articles that met the eligibility criteria. Sixteen\n                    studies reported outcomes related to endurance performance measured through\n                    field-based tests, while five studies provided results from direct measurements\n                    of maximal oxygen uptake (VO2max). Results showed a non-significant\n                    small-magnitude favoring effect for the HIIT groups compared to the SSG groups\n                    (ES=0.37, p=0.074) for endurance, while a non-significant\n                    small-magnitude favoring SSGs was observed (ES=\u20130.20,\n                        p=0.303) for VO2max. Despite the very low certainty of\n                    evidence, the findings suggest similar effects induced by both SSG and HIIT on\n                    improving endurance performance and VO2max.<\/jats:p>","DOI":"10.1055\/a-2171-3255","type":"journal-article","created":{"date-parts":[[2023,9,7]],"date-time":"2023-09-07T23:13:27Z","timestamp":1694128407000},"page":"183-210","source":"Crossref","is-referenced-by-count":24,"title":["Endurance Performance Adaptations between SSG and HIIT in Soccer\n                    Players: A Meta-analysis"],"prefix":"10.1055","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9813-2842","authenticated-orcid":false,"given":"Filipe Manuel","family":"Clemente","sequence":"additional","affiliation":[{"name":"Escola Superior Desporto e Lazer, Instituto Polit\u00e9cnico de\n                    Viana do Castelo, Viana do Castelo, Portugal"},{"name":"Research Center in Sports Performance, Recreation, Innovation and\n                    Technology (SPRINT), Melga\u00e7o, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7452-6855","authenticated-orcid":false,"given":"Jason","family":"Moran","sequence":"additional","affiliation":[{"name":"School of Sport, Rehabilitation and Exercise Sciences, University of\n                    Essex, Colchester, Essex, United Kingdom of Great Britain and Northern\n                    Ireland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2035-3279","authenticated-orcid":false,"given":"Rodrigo","family":"Ramirez-Campillo","sequence":"additional","affiliation":[{"name":"Exercise and Rehabilitation Sciences Institute, Exercise and\n                    Rehabilitation Sciences Institute.
