However, only one study has analysed how the different variables that define SSGs can modify the goalkeeper\u2019s behavior. The aim of the present study was to analyze how the modification of the pitch size in SSGs affects the physical demands of the goalkeepers. Methods: Three professional male football goalkeepers participated in this study. Three different SSG were analysed (62 m \u00d7 44 m for a large pitch; 50 m \u00d7 35 m for a medium pitch and 32 m \u00d7 23 m for a small pitch). Positional data of each goalkeeper was gathered using an 18.18 Hz global positioning system. The data gathered was used to compute players\u2019 spatial exploration index, standard ellipse area, prediction ellipse area The distance covered, distance covered in different intensities and accelerations\/decelerations were used to assess the players\u2019 physical performance. Results and Conclusions: There were differences between small and large SSGs in relation to the distances covered at different intensities and pitch exploration. Intensities were lower when the pitch size was larger. Besides that, the pitch exploration variables increased along with the increment of the pitch size.<\/jats:p>","DOI":"10.3390\/s19163605","type":"journal-article","created":{"date-parts":[[2019,8,19]],"date-time":"2019-08-19T11:22:38Z","timestamp":1566213758000},"page":"3605","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Physical and Tactical Demands of the Goalkeeper in Football in Different Small-Sided Games"],"prefix":"10.3390","volume":"19","author":[{"given":"Daniel","family":"Jara","sequence":"first","affiliation":[{"name":"Department of Physical Activity and Sport, Faculty of Sport Science, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, 30720 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9067-4337","authenticated-orcid":false,"given":"Enrique","family":"Ortega","sequence":"additional","affiliation":[{"name":"Department of Physical Activity and Sport, Faculty of Sport Science, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, 30720 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel-\u00c1ngel","family":"G\u00f3mez-Ruano","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, Polytechnic University of Madrid, 28031 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Weigelt","sequence":"additional","affiliation":[{"name":"Department of Sport and Health, University of Paderborn, 33098 Paderborn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brittany","family":"Nikolic","sequence":"additional","affiliation":[{"name":"Department of Health, Exercise Science and Sport Management, University of Wisconsin-Parkside, Kenosha, WI 53141, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pilar","family":"Sainz de Baranda","sequence":"additional","affiliation":[{"name":"Department of Physical Activity and Sport, Faculty of Sport Science, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, 30720 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"295","DOI":"10.1123\/ijspp.6.3.295","article-title":"Applications of GPS Technologies to Field Sports","volume":"6","author":"Aughey","year":"2011","journal-title":"Int.
