Environmental approaches appear promising: signs that encourage the use of stairs, as well as community campaigns, may increase exercise levels.[126] The city of Bogotá, Colombia, for example, blocks off 113 kilometers (70 mi) of roads on Sundays and holidays to make it easier for its citizens to get exercise. Such pedestrian zones are part of an effort to combat chronic diseases and to maintain a healthy BMI.[127][128]
Making older adults exercise and keeping them in exercise programs is a major challenge. Understanding how older adults prefer to exercise may help developing tailored exercise programs and increase sustained exercise participation in ageing populations. We aimed to describe exercise patterns, including frequency, intensity, type, location and social setting of exercise, in older adults instructed to follow continuous moderate-intensity training (MCT) or high-intensity interval training (HIIT) over a one-year period.
Recruitment criteria were one or both of sedentariness and dysmetabolism. Thus, we selected subjects who were not physically active or involved in any exercise program; that is, they had a sedentary lifestyle. Moreover, before entering the study, they were carefully screened for metabolic problems which attested a dysmetabolic status, as increased levels of plasma glucose, free fatty acids, triglyceride, and urate in fasting state. Both criteria were verified by means of family doctor databases of subjects.
