Light-intensity PA was found to be beneficially associated with obesity , markers of lipid and glucose metabolism , and mortality .
Conclusions Observational evidence that light-intensity PA can confer health benefits is accumulating .
Background The health effects of light-intensity physical activity ( PA ) are not well known today .
Objective We conducted a systematic review to assess the association of accelerometer-measured light-intensity PA with modifiable health outcomes in adults and older adults .
The Finnish Diabetes Prevention Study (DPS): Lifestyle intervention and 3-year results on diet and physical activity.
OBJECTIVE To describe the 1 ) lifestyle intervention used in the Finnish Diabetes Prevention Study , 2 ) short- and long-term changes in diet and exercise behavior , and 3 ) effect of the intervention on glucose and lipid metabolism . RESEARCH DESIGN AND METHODS There were 522 middle-aged , overweight subjects with impaired glucose tolerance who were r and omized to either a usual care control group or an intensive lifestyle intervention group .  The control group received general dietary and exercise advice at baseline and had an annual physician 's examination . The subjects in the intervention group received additional individualized dietary counseling from a nutritionist . They were also offered circuit-type resistance training sessions and advised to increase overall physical activity .  The intervention was the most intensive during the first year , followed by a maintenance period . The intervention goals were to reduce body weight , reduce dietary and saturated fat , and increase physical activity and dietary fiber . RESULTS The intervention group showed significantly greater improvement in each intervention goal . After 1 and 3 years , weight reductions were 4.5 and 3.5 kg in the intervention group and 1.0 and 0.9 kg in the control group , respectively . Measures of glycemia and lipemia improved more in the intervention group . CONCLUSIONS The intensive lifestyle intervention produced long-term beneficial changes in diet , physical activity , and clinical and biochemical parameters and reduced diabetes risk . This type of intervention is a feasible option to prevent type 2 diabetes and should be implemented in the primary health care system
