Gedetailleerde beschrijving
Regular, moderate-intensity physical activity can attenuate hyperglycemia in subjects with type 2 diabetes. In addition, these programmes may favourably affect several other cardiovascular risk factors in these subjects. However, it still remains unclear how this evidence can be transferred into clinical practice, considering the very large number of diabetic patients and the characteristics of this population, made up predominantly of elderly, sedentary and overweight patients. In this regard, a realistic approach to this issue requires simple and easily available intervention models.
Walking is a typical mild-moderate aerobic physical activity which is easy to organize and does not require specific skills or preliminary sophisticated medical evaluations. This activity could therefore fit well with the need of involvement of large numbers of patients in different logistic situations. However, it has been reported that, due to the low walking speed typical of type 2 diabetic subjects, self-paced walking is inadequate to obtain a significant metabolic improvement in these subjects.

Overstappen op 6 minuten loopafstand
Tijdsspanne: 4 maanden
|
Deze test meet het aantal meters dat in 6 minuten gelopen kan worden over een parcours van 30 m.
Het is een eenvoudige veldtest om de aerobe functionele capaciteit te beoordelen.
|

|
Change in C-reactive protein levels
Tijdsspanne: 4 months
|
4 months
|
|
|
Change in Energy expenditure through voluntary physical activity
Tijdsspanne: 4 months
|
Energy expenditure is estimated through 7-day activity diaries.
The intensity of each activity (defined in metabolic equivalents, MET) is multiplied by duration and the product for each activity is summed to give a total activity score in MET hours/week.
|
4 months
|
|
Change in Antidiabetic medications
Tijdsspanne: 4 months
|
Class and dosage of blood-glucose lowering drugs are recorded before and at the end of the protocol, to assess changes in hypoglycemic medication during the trial.
|
4 months
|
|
Compliance with walking sessions
Tijdsspanne: 4 months
|
Attendance at the scheduled walking sessions is recorded for each patient.
