Methods<\/jats:bold><\/jats:italic>: Twenty-four male youth soccer players (16.3\u2009\u00b1\u20090.8\u00a0y old) participating at the trained\/developmental level underwent monitoring for psychophysiological responses (including heart rate, rating of perceived exertion, and visual analog scale), locomotor demands (such as distance covered), and technical performance variables (including successful and unsuccessful passes and shots, as well as lost balls) across 2v2 and 4v4 formats. These formats were applied 4 times within a single session and were replicated twice over 2\u00a0weeks. Results<\/jats:bold>:<\/jats:italic> Large correlations between the number of lost balls per minute and mean heart rate were found in both the 2v2 and 4v4 games (r<\/jats:italic>\u2009=\u2009.586 and r<\/jats:italic>\u2009=\u2009.665, respectively). Successful shots were inversely and largely correlated with mean heart rate (r<\/jats:italic>\u2009=\u2009\u2212.518) in 4v4 games. The number of interceptions per minute was inversely and significantly correlated with the visual analog scale in 2v2 and 4v4 games (r<\/jats:italic>\u2009=\u2009\u2212.455 and r<\/jats:italic>\u2009=\u2009\u2212.710, respectively). The frequency of lost balls was significantly higher among players who attained a higher mean heart rate (2v2: +42.9%, P<\/jats:italic>\u2009=\u2009.031, d<\/jats:italic>\u2009=\u2009\u22120.965; 4v4: +57.1%, P<\/jats:italic>\u2009<\u2009.001, d<\/jats:italic>\u2009=\u2009\u22122.072). Conclusions<\/jats:bold>:<\/jats:italic> Coaches should be aware that highly psychophysiologically demanding scenarios may significantly impair technical performance. Therefore, prioritizing technical performance by deliberately adjusting the intensity should be considered.<\/jats:p>","DOI":"10.1123\/ijspp.2024-0003","type":"journal-article","created":{"date-parts":[[2024,4,1]],"date-time":"2024-04-01T19:17:46Z","timestamp":1711999066000},"page":"576-584","source":"Crossref","is-referenced-by-count":5,"title":["Greater Psychophysiological Intensities in Conditioned Games May Impair Technical Performance: An Exploratory Study in Youth Male Soccer Players"],"prefix":"10.1123","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9813-2842","authenticated-orcid":true,"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, Viana do Castelo, Portugal"},{"name":"Sport Physical Activity and Health Research & Innovation Center, Viana do Castelo, Portugal"},{"name":"Gdansk University of Physical Education and Sport, Gda\u0144sk, Poland"}]}],"member":"100","reference":[{"issue":"3","key":"r1","series-title":"Exerc Sport Sci Rev","doi-asserted-by":"publisher","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 K","year":"2013","unstructured":"Davids K, Ara\u00fajo D, Correia V, Vilar L.
