Original ArticleSupervised group-exercise therapy versus home-based exercise therapy: Their effects on Quality of Life and cardiovascular risk factors in women with type 2 diabetes
Introduction
In combination with dietary and pharmacological treatment, exercise is an integral part of diabetes care [1], [2]. Although people with type II diabetes are generally recommended to exercise according to clinical guidelines, these guidelines contain no particular information on the types of exercise that will maximise clinical benefits [3]. The few studies to have compared the effects of supervised group exercise therapy with home-based programs on health-related quality of life (HRQOL) have published contradictory results. For example, while Vadstrup et al. found no significant differences between the two groups [4]. Nicolucci et al. found the supervised exercise program to improve quality of life more effectively than counselling alone [5].
Patients with diabetes need the best possible exercise program, i.e., programs that are appropriate to the demographic, social, cultural and ethnic characteristics’ of their population. Those programs should be designed on the basis of a number of studies with a specific focus on these variables in each country. Therefore, we compared the effects of supervised group-exercise therapy (SET) and home-based exercise therapy (HET) in Iranian women with type II diabetes over 12 weeks, focusing specifically on health-related quality of life (HRQOL), glycaemic control, lipid profile and anthropometric parameters.

Methods
This randomized clinical trial study was carried out for 12 weeks after approval by the Ethics Committee at Iran University of Medical Sciences. Iran registry of clinical trials number of this research is 201011044251N3. The study included 102 women with type 2 diabetes who had been referred to the following institutes between October 2011 and October 2012: the Endocrine Research Centre at Firouzgar Hospital, Endocrine and Metabolic clinics in the southern districts of Tehran, Imam Khomeini
Results
After screening 589 diabetic women, we enrolled 102 eligible participants in this study, who were randomly allocated to two exercise-therapy groups. After the baseline visit, 36 patients in the HET group and 38 patients in the SET group attended at least one of the pre-determined exercise-therapy visits (in week 6 and week 12).
Discussion
Our findings show that, over the 12 weeks of the intervention, the SET program improved some of the HRQOL items and anthropometric parameters in diabetic women more effectively than the HET program did. Nonetheless, the HET program also improved a number of outcomes, especially lipid profile, HbA1c, and FBG; and also some HRQOL items and anthropometric parameters.
With regard to HRQOL, comparison of our study with other studies showed a wider variety of QOL outcomes between studies. In our own
Comments
Our findings demonstrated that supervised group-exercise therapy is more effective than home-based exercise therapy in improving QOL and body composition in diabetic II women.
However, the effectiveness of home-based exercise therapy on glycaemic control, body composition and lipid profile is also significant. Important roles in promoting physical activity and health outcomes of diabetic patients in supervised or home-based exercise settings can thus be played (1) by minimal interventions such

2018, Journal of Medical Imaging and Radiation SciencesCitation Excerpt :Exercise has been proven to be advantageous in the management of other chronic illnesses such as coronary disease [33]. Cochrane reviews to this end have illustrated the benefit of supervised exercise programmes over home-based interventions [34,35], Further noncancer RCTs strengthen this finding [36]. A cancer review by Velthius et al [22] on multiple cancer sites also highlighted the benefit of supervised programmes compared with that of home-based interventions in breast cancer patients.

Similarly, WC was significantly reduced in five studies [27,30,32,35,38], three of which were exercise based interventions [27,32,38], one of which combined diet and exercise [35], and the final included a hypocaloric diet and restricted diet beverages or water consumption [30].
