Hence, it has been widely encouraged as a measure by which to combat somatic and psychological ailments. In view of the technical progress, the aging society and the public life restrictions issued during the COVID-19 pandemic, the delivery of interventions using digital devices has become highly popular.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"objective\">\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This systematic review and meta-analysis aimed to examine the effects of online exercise programs on physical activity (PA), motor performance, and mental health.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Two independent investigators performed a systematic literature search, using PubMed, Cochrane Library, and Google Scholar. Randomized controlled trials assessing the effects of online exercise (OE) versus no exercise or face-to-face exercise (FFE) in healthy adults were included. Effect sizes (standardized mean difference [SMD]) were pooled using robust variance estimation. The quality of the included studies was assessed by 2 independent reviewers applying the PEDro scale, and publication bias was checked by means of funnel plots. To determine the certainty about the evidence, the results were rated by means of the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 18 articles with moderate to high methodological quality (7\/10 points on the PEDro scale), including a total of 3571 participants, were identified. Visual inspection of funnel plots provided indications of a publication bias for 2 out of 16 outcomes. According to the meta-analysis, OE was superior to no exercise regarding strength (SMD=0.61, 95% CI 0.06 to 1.15, n=5 studies), balance (SMD=0.52, 95% CI 0.06 to 0.99, n=4 studies), endurance (SMD=0.85, 95% CI \u22120.01 to 1.70, n=5 studies), PA (SMD=0.46, 95% CI 0.05 to 0.87, n=5 studies), depression (SMD=1.08, 95% CI \u22120.01 to 2.16, n=4 studies), mood or emotion (SMD=0.47, 95% CI 0.05 to 0.90, n=5 studies), mental well-being (SMD=0.79, 95% CI 0.06 to 1.52, n=4 studies), and self-efficacy (SMD=1.1, 95% CI 1.03 to 1.17, n=3 studies). Compared to FFE, OE was noninferior (\n                      <jats:italic>P<\/jats:italic>\n                      &gt;.05) except for gait speed which improved more following FFE (SMD=0.25, 95% CI 0.24 to 0.26, n=2 studies). The certainty about the evidence (GRADE criteria) was low to moderate for all comparisons.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>OE represents an effective strategy to improve PA, physical function, and mental health in healthy adults and may hence help combat physical inactivity. However, despite the encouraging findings, some limitations need to be tackled before drawing definitive conclusions. These, inter alia, include a small total number of studies and substantial between-trial heterogeneity for some outcomes. Furthermore, as this review focused on healthy adults, future research examining other populations (eg, children and adolescents) is needed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/64856","type":"journal-article","created":{"date-parts":[[2025,5,5]],"date-time":"2025-05-05T17:50:28Z","timestamp":1746467428000},"page":"e64856-e64856","source":"Crossref","is-referenced-by-count":7,"title":["The Effectiveness of Online Exercise on Physical Activity, Motor Function, and Mental Health: Systematic Review and Meta-Analysis"],"prefix":"10.2196","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1353-7459","authenticated-orcid":false,"given":"Adelle Kemlall","family":"Bhundoo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8502-8878","authenticated-orcid":false,"given":"Julian David","family":"Pillay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9147-2369","authenticated-orcid":false,"given":"Jan","family":"Wilke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,8,15]]},"reference":[{"issue":"6","key":"R1","doi-asserted-by":"publisher","first-page":"801","DOI":"10.1503\/cmaj.051351","article-title":"Health benefits of physical activity: the evidence","volume":"174","author":"Warburton","journal-title":"CMAJ"},{"issue":"2-2","key":"R2","doi-asserted-by":"publisher","first-page":"343","DOI":"10.13187\/issn.2219-8229","article-title":"Lifestyle, physical and sports education and health benefits of physical activity","author":"Bend\u00edkov\u00e1","journal-title":"European researcher"},{"issue":"3","key":"R3","first-page":"131","volume":"58","author":"McKinney","journal-title":"B C Med J"},{"issue":"7","key":"R4","doi-asserted-by":"publisher","first-page":"925","DOI":"10.1007\/s40279-016-0535-8","article-title":"Designing Environments to Enhance Physical and Psychological Benefits of Physical Activity: A Multidisciplinary Perspective","volume":"46","author":"Brymer","journal-title":"Sports Med"},{"issue":"10","key":"R5","doi-asserted-by":"publisher","first-page":"710","DOI":"10.13189\/ujer.2015.031008","article-title":"Psychological Benefits of Regular Physical Activity: Evidence from Emerging Adults","volume":"3","author":"Cekin","journal-title":"ujer"},{"issue":"3","key":"R6","doi-asserted-by":"publisher","first-page":"177","DOI":"10.47626\/2237-6089-2021-0237","article-title":"Physical activity, exercise, and mental disorders: it is time to move on","volume":"43","author":"Schuch","journal-title":"Trends Psychiatry Psychother"},{"issue":"1","key":"R7","doi-asserted-by":"publisher","first-page":"125","DOI":"10.1037\/xap0000333","article-title":"Experimental evidence for the effects of job demands and job control on physical activity after work","volume":"27","author":"Abdel Hadi","journal-title":"J Exp Psychol Appl"},{"issue":"9838","key":"R8","doi-asserted-by":"publisher","first-page":"219","DOI":"10.1016\/S0140-6736(12)61031-9","article-title":"Effect of physical inactivity on major non-communicable diseases worldwide: an analysis of burden of disease and life expectancy","volume":"380","author":"Lee","journal-title":"The Lancet"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.1097\/HCO.0000000000000437","article-title":"Health benefits of physical activity: a systematic review of current systematic reviews","volume":"32","author":"Warburton","journal-title":"Curr Opin Cardiology"},{"issue":"9838","key":"R10","doi-asserted-by":"publisher","first-page":"294","DOI":"10.1016\/S0140-6736(12)60898-8","article-title":"The pandemic of physical inactivity: global action for public health","volume":"380","author":"Kohl","journal-title":"The Lancet"},{"key":"R11","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-med-060619-022943","article-title":"The Role of Exercise in Management of Mental Health Disorders: An Integrative Review","volume":"72","author":"Smith","journal-title":"Annu Rev Med"},{"key":"R12","unstructured":"United Nations Department of Economic and Social Affairs. 2023.
