“…Looking at the cardiometabolic blood markers, WE had no effect on lipids and FBG. This is in contrast to a previous study which demonstrated positive effects of WE on FBG and TC [44]. However, the participants were adults with type 2 diabetes, which would explain the beneficial effects of the interventions given that exercise is more effective for improving metabolic outcomes in those with initially higher values [45].…”

Background: Visceral adipose tissue (VAT) is a strong risk factor for cardiovascular disease and increases with age. While supervised exercise (SE) may be an effective approach, web-based exercise (WE) have other advantages such as being more readily accessible. Therefore, we evaluated the effects of WE on VAT, body composition and cardiometabolic risk markers in centrally obese older adults and compared the effects of WE to SE. We also explored the feasibility of WE. Methods: In a randomized controlled trial conducted in Umeå, Sweden during January 2018-November 2018, N = 77, 70-year-old men and women with central obesity (> 1 kg VAT for women, > 2 kg for men) were randomized to an intervention group (n = 38) and a wait-list control group (n = 39). The intervention group received 10 weeks of SE while the wait-list control group lived as usual. Following a 10-week wash-out-period, the wait-list control group received 10 weeks of WE. The primary outcome was changes in VAT. Secondary outcomes included changes in fat mass (FM), lean body mass (LBM), blood lipids, fasting blood glucose. Additionally, we explored the feasibility of WE defined as adherence and participant experiences. Results: WE had no significant effect on VAT (P = 0.5), although it decreased FM by 450 g (95% confidence interval [CI], 37 to 836, P < 0.05). The adherence to WE was 85% and 87-97% of the participants rated aspects of the WE intervention > 4 on a scale of 1-5. Comparing SE to WE, there was no significant difference in decrease of VAT (Cohen's δ effect size [ES], 0.5, 95% CI, − 24 to 223, P = 0.11), although SE decreased FM by 619 g (ES, 0.5, 95% CI, 22 to 1215, P < 0.05) compared to WE. Conclusions: Ten weeks of vigorous WE is insufficient to decrease VAT in centrally obese older adults, but sufficient to decrease FM while preserving LBM. The high adherence and positive experiences of the WE intervention implies that it could serve as an alternative exercise strategy for older adults with central obesity, with increased availability for a larger population.

“…BMI was measured in four of the studies, while body fat percentage (BFP) and BW were measured in three studies. For the three studies where data were presented for both an IG and a CG (Akinci et al 2018;Thompson et al 2014;Wijsman et al 2013), there were significant decreases in WC in favor of the intervention within two of the studies. Specifically, in the study by Akinci et al, the IG decreased WC by a more than 5 cm compared to the CG (P \ 0.05) in the absence of effect on BMI.…”

“…The nature of digital exercise intervention varied widely between the five included studies. Akinci et al (2018) randomized participants to an IG and a CG. The CG received a brochure with information about health and exercise while the IG performed three exercise sessions for eight weeks, where each session lasted 50-60 min.…”

“…In the study by Akinci et al (2018), over 52% of the participants in the IG were excluded due to insufficient adherence to the intervention. Specifically, 28.5% of the participants never visited the website and 23.8% failed to complete the exercise program for three consecutive weeks.…”

“…Similarly, 60% of the studies did not state whether the outcome assessment was blinded or not. Additionally, in one study Akinci et al (2018), there was a high risk of attrition bias given that inappropriate methods were employed for handling missing data, resulting in potentially over-estimated effects. Also, data on changes in body fat were not reported in this study despite stated in the pre-registered study protocol.…”

Objectives We aimed to systematically review the potential benefits of digital exercise interventions for improving measures of central obesity including visceral adipose tissue (VAT) and anthropometric surrogates for VAT in overweight or centrally obese adults aged 18 or over. Methods A systematic literature search was conducted in three databases up until March 2020 (PROSPERO registration nr CRD42019126764). Results N = 5 studies including 438 participants (age 48-80) with body mass index C 25 kg/m 2 met the eligibility criteria and were included. The duration of the interventions ranged from 8 to 24 weeks. No study measured the primary outcome VAT, although in N = 4 studies, waist circumference (WC) decreased by between 1.3 and 5.6 cm in the intervention groups. Conclusions This systematic review shows that there is no evidence for the effects of digital exercise on VAT, although digital exercise may decrease WC. These findings highlight the need for additional randomized controlled trials to confirm the findings with respect to WC, and to further investigate the effects of digital exercise on VAT. Together, this may have important implications for reducing the burden of physical inactivity and obesity.

Type 2 diabetes is a chronic disease, requiring lifestyle management to prevent chronic complications. Increasing physical activity and reducing sedentary behavior are integral to maintaining glycemic control. The purpose of this study was to (1) appraise and synthesize the literature about physical activity and sedentary behavior intervention delivery via telehealth strategies in adults with type 2 diabetes mellitus and (2) to evaluate what is known about the effectiveness of such interventions on physical activity, sedentary behavior, and glycemic control. An integrative literature review was carried out, including the electronic databases PubMed, CINAHL, and PsychInfo, searching for articles published within the past 10 years, meeting specified inclusion and exclusion criteria, following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement guidelines. Seventeen studies were included. Significant improvements in physical activity and sedentary behavior were identified in web and mobile phone‐based interventions. Modest improvements in glycemic control were reported. Theoretical framework use and integration was limited, and intervention length and follow‐up varied greatly in the studies reviewed. Outcomes were measured using both self‐report and objective measures, but objective measures were used less frequently. Further, few studies have been conducted in the United States or in rural populations. Web and mobile phone‐based telehealth interventions to increase physical activity, reduce sedentary behaviors, and improve glycemic control have been supported by the literature. A need exists for future studies that are theory‐driven, include dose‐specific measures, self‐report and objective measures, and long‐term follow‐up. Examining intervention effects in rural populations is needed.

The effects of Internet-based exercise compared with supervised group exercise in people with type 2 diabetes: a randomized controlled study

Abstract: In type 2 diabetes, supervised group-based and Internet-based exercise can improve equally glycaemic control, waist circumference, and quality of life, and both are better than simply counselling.
