Ten recreational U-17 soccer players participated in this study (16.89 \u00b1 0.11 years). We used different strategies of task manipulation to design two 4 vs. 4 SSCG: Structural SSCG and Functional SSCG. In Structural SSCG, pitch format and goal sizes were manipulated, while in Functional SSCG, players were allowed to kick the ball twice and at least 5 passes to shoot at the opponent\u2019s goal. Players participated in four Structural and Functional SSCG, of five minutes duration with a two-minute interval in between. Players\u2019 physical performance and tactical behavior were assessed using the WIMU PROTM inertial device. Structural SSCG stimulated players to cover more distance in sprinting (p = 0.003) and high-speed running (p &lt; 0.001). Regarding tactical behavior, Structural SSCG stimulated players to explore game space better (p &lt; 0.001). Moreover, Functional SSCG stimulated players to be closer to the ball, decreasing the effective playing space (p = 0.008). We conclude that these strategies of task constraint manipulation impact physical and tactical demands of the game.<\/jats:p>","DOI":"10.3390\/s22124435","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T02:01:44Z","timestamp":1655085704000},"page":"4435","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Applying Different Strategies of Task Constraint Manipulation in Small-Sided and Conditioned Games: How Do They Impact Physical and Tactical Demands?"],"prefix":"10.3390","volume":"22","author":[{"given":"Jo\u00e3o Cl\u00e1udio","family":"Machado","sequence":"first","affiliation":[{"name":"Faculty of Physical Education and Physiotherapy, Federal University of Amazonas, Manaus 69067-005, Brazil"}]},{"given":"Alberto","family":"G\u00f3es","sequence":"additional","affiliation":[{"name":"Faculty of Physical Education, State University of Campinas, Campinas 13083-859, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4885-7316","authenticated-orcid":false,"given":"Rodrigo","family":"Aquino","sequence":"additional","affiliation":[{"name":"LabSport, Post-Graduate Program in Physical Education, Center of Physical Education and Sports, Federal University of Esp\u00edrito Santo, Vit\u00f3ria 29075-910, Brazil"}]},{"given":"Bruno L.
