This phenomenon is particularly dangerous in children, because it negatively affects their later existence in the health, mental and social spheres. This phenomenon is particularly concerning in the pediatric population, as it may have long-term adverse effects on physical health, psychological well-being, and social functioning. Objective: The aim of this study was to assess anthropometric parameters and physical fitness using the EUROFIT test in children and adolescents diagnosed with obesity. Materials and Methods: The study group consisted of 123 pediatric patients attending the Endocrinology and Diabetology Clinic and Pediatric Rehabilitation IP-CZD aged 8\u201316 (64 boys\u201452% and 59 girls\u201448%) with diagnosed simple obesity. Obesity was diagnosed according to the CDC standard using percentile charts from the OLAF study. Physical fitness was assessed using the EUROFIT test using 8 samples, and body mass composition was examined using the bioimpedance method with the BC 418 Tanita analyzer. Results: The results of our own research obtained in this study were compared to population standards. The total results of the EUROFIT test in the study group were statistically significantly lower than the norm. The results of the balance, upper limb movement speed, jumping, trunk strength, functional strength and agility tests were lower than the norm, the flexibility result was within the norm, and only hand strength was higher than the norm. In 4 out of 8 fitness tests, girls achieved significantly better results than boys. Conclusions: Reduced physical fitness is characteristic of children and adolescents with simple obesity. Worse physical fitness shows significant correlations with the results of anthropometric measurements.<\/jats:p>","DOI":"10.3390\/children12101388","type":"journal-article","created":{"date-parts":[[2025,10,15]],"date-time":"2025-10-15T07:17:52Z","timestamp":1760512672000},"page":"1388","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Assessment of Physical Fitness in Children and Adolescents with Simple Obesity"],"prefix":"10.3390","volume":"12","author":[{"given":"Jacek","family":"Podogrodzki","sequence":"first","affiliation":[{"name":"Department of Neurology and Epileptology, The Children\u2019s Memorial Health Institute, Aleja Dzieci Polskich 20, 04-730 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2950-761X","authenticated-orcid":false,"given":"Mieczys\u0142aw","family":"Szalecki","sequence":"additional","affiliation":[{"name":"Clinic of Endocrinology and Diabetology, The Children\u2019s Memorial Health Institute, Aleja Dzieci Polskich 20, 04-730 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Wrona","sequence":"additional","affiliation":[{"name":"Department of Science, The Children\u2019s Memorial Health Institute, Aleja Dzieci Polskich 20, 04-730 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9578-8894","authenticated-orcid":false,"given":"Aldona","family":"Wierzbicka-Ruci\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Clinical Biochemistry, The Children\u2019s Memorial Health Institute, Aleja Dzieci Polskich 20, 04-730 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"658","DOI":"10.1007\/s11684-018-0640-1","article-title":"Epidemic obesity in children and adolescents: Risk factors and prevention","volume":"12","author":"Lee","year":"2018","journal-title":"Front.
