Interventions such as SmartACT, which integrate mindfulness, acceptance, and commitment, guided imagery and hypnosis techniques are still underexplored in high-performance sport, despite their potential to affect both psychological and motor dimensions. Methods: This 7-week controlled trial investigated the effectiveness of SmartACT in reducing psychological and somatic symptoms and enhancing motor performance in adolescent athletes. A total of 193 athletes aged 15\u201318 years were assigned to three groups: SmartACT (n = 69), MAC (Mindfulness\u2013Acceptance\u2013Commitment, the standardized Gardner &amp; Moore protocol; n = 65), and a control group (n = 59). Agility was measured using the T-Drill Agility Test with Microgate electronic timing, and reaction speed was assessed using BlazePod devices. Psychological and somatic symptoms were evaluated using the Depression, Anxiety, and Stress Scale (DASS-21) and the Ghent Multidimensional Somatic Complaints Scale (GMSCS). Results: The SmartACT group showed significantly improved agility (MD = \u22121.07 s, p &lt; 0.001, d = 2.50, 95% CI [1.79, 3.35]), faster reaction times (MD = \u2212643.75 ms, p &lt; 0.001, d = 0.85, 95% CI [0.35, 1.41]), and a higher number of BlazePod touches (MD = +2.53, p &lt; 0.001, d = 1.43, 95% CI [0.87, 2.07]). Psychological symptoms (DASS-21) and somatic complaints (GMSCS) decreased significantly more than in the MAC and control groups. Conclusions: SmartACT appears to be an effective hybrid psychological intervention to simultaneously improve physical performance and reduce psychological and psychosomatic distress in adolescent athletes.<\/jats:p>","DOI":"10.3390\/children12101338","type":"journal-article","created":{"date-parts":[[2025,10,6]],"date-time":"2025-10-06T08:10:51Z","timestamp":1759738251000},"page":"1338","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effects of the SmartACT Intervention on Motor and Psychological Variables in Adolescent Athletes: A Controlled Trial Using BlazePod and Microgate"],"prefix":"10.3390","volume":"12","author":[{"given":"Barab\u00e1si Mad\u00e1r","family":"Timea","sequence":"first","affiliation":[{"name":"Faculty of Physical Education and Sport, \u201cBabes-Bolyai\u201d University, Mihail Kog\u0103lniceanu 1, 400347 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Costea-B\u0103rlu\u0163iu","family":"Carmen","sequence":"additional","affiliation":[{"name":"Faculty of Psychology and Educational Sciences, \u201cBabes-Bolyai\u201d University, Sindicatelor 7, 400347 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ordean Mircea","family":"Nicolae","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, \u201cDecember 1, 1918\u201d University, Gabriel Bethlen 5, 510009 Alba Iulia, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-4566-6417","authenticated-orcid":false,"given":"Mancini","family":"Nicola","sequence":"additional","affiliation":[{"name":"Department of Science of Education and Sport, Pegaso Telematic University, 80143 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4846-4491","authenticated-orcid":false,"given":"Grosu Vlad","family":"Teodor","sequence":"additional","affiliation":[{"name":"Faculty of Industrial Engineering, Robotics, and Production Management, Technical University of Cluj-Napoca, Muncii 103-105, 400461 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sab\u0103u Anca","family":"Maria","sequence":"additional","affiliation":[{"name":"Departament of Physical Education and Sport and Kinetotherapy, Faculty of Geography, Turism and Sport, University of Oradea, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4825-6000","authenticated-orcid":false,"given":"Popovici","family":"Cornelia","sequence":"additional","affiliation":[{"name":"Physical Education Discipline, University of Medicine and Pharmacy \u201cIuliu Ha\u021bieganu\u201d, Pasteur 6, 400347 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0904-9041","authenticated-orcid":false,"given":"Carlos","family":"Herv\u00e1s-G\u00f3mez","sequence":"additional","affiliation":[{"name":"Department of Teaching and Educational Organization, University of Sevilla, 41013 Sevilla, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2846-9586","authenticated-orcid":false,"given":"Grosu Emilia","family":"Florina","sequence":"additional","affiliation":[{"name":"Faculty of Physical Education and Sport, \u201cBabes-Bolyai\u201d University, Mihail Kog\u0103lniceanu 1, 400347 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1426-2901","authenticated-orcid":false,"given":"Monea","family":"Dan","sequence":"additional","affiliation":[{"name":"Faculty of Physical Education and Sport, \u201cBabes-Bolyai\u201d University, Mihail Kog\u0103lniceanu 1, 400347 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1469","DOI":"10.1016\/j.jpeds.2014.01.071","article-title":"Sports participation and parent-reported health-related quality of life in children: Longitudinal associations","volume":"164","author":"Vella","year":"2014","journal-title":"J.
