Due to these self-perceived barriers, the aim of our study was to evaluate the efficacy of an online training program on self-reported physical fitness (SRPF) in children with obesity (OB).<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>   \n<jats:p>A total of 32 children with OB carried out physical fitness (PF) tests and were asked to complete the International Fitness Enjoyment Scale (IFIS) questionnaire. The physical fitness tests were the Standing Broad Jump (SBJ), the 6-Min Walking Test (6MWT) and the 4 \u00d7 10 m sprint test. Children participated in a 3-weekly 60-min training session through Zoom platform. Before the beginning of the training protocol, OB children were compared with normal weight (NW) ones for PF batteries and the IFIS questionnaire. Changes in performances after the training were assessed by paired Student t and Wilcoxon tests.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>After the online training program children increased their performance in 6MWT (mean difference (MD) = 54.93; <jats:italic>p<\/jats:italic> &lt; 0.0001) in SBJ (MD = 10.00; <jats:italic>p<\/jats:italic> = 0.0001) and in 4 \u00d7 10 m sprint test (MD = \u22120.78; <jats:italic>p<\/jats:italic> &lt; 0.0001).

Instead, the lack of differences in SRPF after the training suggests interesting questions to be explored on the aspects linked to self-perception. Therefore, even if our training protocol could not directly improve SRPF in children with obesity, the enhancement of their PF could be a starting point for achieving this result with a longer training period and consequently improve PA participation for children with OB.<\/jats:p>\n<\/jats:sec>","DOI":"10.7717\/peerj.15765","type":"journal-article","created":{"date-parts":[[2023,7,31]],"date-time":"2023-07-31T10:02:36Z","timestamp":1690797756000},"page":"e15765","source":"Crossref","is-referenced-by-count":1,"title":["International
