Virtual Reality (VR) technology to support conventional exercise has recently gained much attention. Therefore, this study aimed to assess the effects of traditional treadmill exercise compared to virtual reality-simulated treadmill exercise on fatigue, cognitive function, sleep quality, and participant satisfaction with the exercise program in post-COVID-19 subjects.</p></div><div><h3>Methods</h3><p>This single-centered, randomized, parallel-group intervention study was conducted between December 2021 and March 2022. Sixteen of twenty post-COVID-19 subjects completed this study (n1 = 8, n2 = 8). Inclusion criteria were persistent dyspnea/fatigue, mild cognitive problems, and age from 30<strong>–</strong>60 years. Exclusion criteria were previous severe COVID-19 infection and ICU admission, concomitant respiratory or cardiovascular disease, and musculoskeletal or neurological disease. Eligible subjects were assigned randomly to two groups: a non-VR group that received traditional treadmill aerobic exercise only and a VR group that received treadmill exercise with non-immersive VR. Both groups received moderate-intensity exercise on a treadmill at [50<strong>–</strong>60 % (peak HR－resting HR) + resting HR] for 30<strong>–</strong>45 min, three times per week, and for four weeks. The outcome measures were the Chalder Fatigue Scale, Montreal Cognitive Assessment (MoCA) questionnaire, Pittsburgh Sleep Quality Index (PSQI), and participant satisfaction with the exercise program rated on a 5-point Likert scale.</p></div><div><h3>Results</h3><p>Both groups showed significant improvements in the Chalder Fatigue Scale, the MoCA questionnaire, and the PSQI scores after training compared to baseline (p &lt; 0.05), without significant differences between them (p &gt; 0.05). However, participant satisfaction with the exercise program was significantly higher in the VR group than in the non-VR group (p = 0.037).</p></div><div><h3>Conclusion</h3><p>A moderate-intensity 4-week treadmill exercise program with and without non-immersive VR may improve fatigue, cognitive function, and sleep quality to the same extent in COVID-19 survivors. However, participant satisfaction with the exercise program could be greater after conventional treadmill training assisted by non-immersive VR than after conventional treadmill training alone in this cohort.</p></div><div><h3>Trial registration</h3><p>Pan African Clinical Trials Registry, PACTR202311561948428, retrospectively registered.</p></div>","PeriodicalId":15793,"journal":{"name":"Journal of Exercise Science & Fitness","volume":"22 4","pages":"Pages 316-321"},"PeriodicalIF":2.8,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1728869X24000388/pdfft?md5=853d355480ad6af16724cafd515b7df3&pid=1-s2.0-S1728869X24000388-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140794036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this review was to identify the scope and gaps in the measurement of active play based on data gathered from 68 countries that participated in the Global Matrix (GM) initiative, led by the Active Healthy Kids Global Alliance (AHKGA). GM is the global-level, biennial evaluation system of physical activity related behaviors among children and youth, including the Active Play indicator, and the sources of influence using letter grades (ranging between “A” and “F”). Based on the identified scope and gaps, this study offers recommendations for future research dedicated to the measurement/surveillance of active play. Out of the 68 countries involved in the previous GM (2014–22), 55% of the grades remained unassigned due to insufficient data on the Active Play indicator. The high number of unassigned grades, combined with the absence of valid measurement tool, highlight a need for a standardized measurement tool for improved global data generation of active play among children and youth. Our findings emphasize the need to address challenges in measuring active play. This review offers future considerations, research recommendations specific to the GM initiative, and two sets of age- and location-specific (indoor and outdoor settings) questionnaire items along with guidelines for its use.

We hypothesize SCD will improve these markers in a dose-response manner following a mixed meal.</p></div><div><h3>Methods</h3><p>In a randomized, controlled, crossover trial, young adults (N = 31) performed SCD for 0 (seated control), 1, 3, and 10 minutes after a mixed meal (650 kilocalories; 53% carbohydrates, 33% fat, and 14% protein). Differences in glucose, insulin, and insulin sensitivity (ISI) from baseline to 30 min were analyzed using a mixed-effects ANOVA.</p></div><div><h3>Results</h3><p>A significant fixed-effect was found for change in glucose [F(2.551,67.17) = 4.724,p = 0.007)], insulin [F(2.692,74.49) = 11.28,p &lt; 0.001)], and ISI [F(2.127,56.00) = 5.848,p = 0.004)]. Compared to the seated control (0 minutes), changes in glucose were lower after 1 minute (−14.0 (−7.2)mg/dL,p &lt; 0.001), 3 minutes (−18.4 (−7.0)mg/dL,p = 0.0007), and 10 minutes (−10.0 (−8.1)mg/dL,p = 0.039); changes in insulin were lower after 1 minute (−1.8 (−0.9)μIU/mL,p = 0.0011), 3 minutes (−2.8 (−0.9)μIU/mL,p &lt; 0.001), and 10 minutes (−1.1 (−0.9)μIU/mL,p = 0.033); and changes in ISI were significantly higher after 3 minutes (2.4 (1.5),p &lt; 0.001) and 10 minutes (1.3 (1.6),p = 0.014) but not 1 minute (1.2 (1.5),p = 0.059).</p></div><div><h3>Conclusion</h3><p>Postprandial glucose and insulin improved with 1 minute, and insulin resistance improved with 3 minutes, of SCD at a self-selected, comfortable pace, after consumption of a mixed meal in apparently healthy young adults.</p></div><div><h3>Protocol</h3><p>Trial registration: <span>ClinicalTrials.gov</span><svg><path></path></svg> Identifier: NCT04232475.</p></div>","PeriodicalId":15793,"journal":{"name":"Journal of Exercise Science & Fitness","volume":"22 3","pages":"Pages 266-270"},"PeriodicalIF":2.8,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1728869X24000200/pdfft?md5=862dbf72c8a41d672ed629418a13a215&pid=1-s2.0-S1728869X24000200-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140199731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
