Effekten av instruktörsledd träning vidövervikt och obesitas : En strukturerad litteraturstudie

Sammanfattning

Health effects from physical activity and exercise fail to manifest when individuals with overweightand obesity experience barriers to engaging in physical exercise.The aim of this structured literature review was therefore to investigate the effect of instructor-ledexercise on (1) body weight, (2) body measurements, and (3) body composition in adult men andwomen with overweight and obesity.A systematic search in PROSPERO, PubMed, Cinahl, and SPORTDiscus confirmed that no previoussystematic reviews had been conducted on this research question. Quality assessment was carriedout using SBU’s appraisal templates, and an independent review of the selection process and qualityassessment was performed by a supervisor.Eight randomized controlled trials (635 participants) were included, of which four were assessed ashaving a moderate risk of bias and four a high risk of bias.The results indicated that instructor-led exercise, when combined with dietary intervention andendurance or combined training, may have beneficial effects for individuals with overweight andobesity. However, further research with stronger methodological quality is needed to explore thistopic in greater depth.Instructor-led exercise does not appear to prevent compensatory behavioral patterns in response toincreased energy expenditure, which should be further investigated.
