lichte beweging ook al goed.
The dose-response relationship was seen across age, race, weight, baseline fitness, and hormone therapy subgroups.
Participants’ systolic and diastolic blood pressure levels, weight, and most other cardiovascular risk factors were not significantly altered with any level of exercise.
However, waist circumference, which was similar in each group at baseline, was significantly reduced at the end of the study in all 3 exercise groups compared with the control group (p<0.05 for each). This was a significant finding given the importance of increased risk of insulin resistance, diabetes, and metabolic syndrome, and mortality associated with abdominal obesity, Church and team emphasize.
“Perhaps the most striking finding of our study is that even activity at the 4-kcal/kg per week level (approximately 72 min per week) was associated with a significant improvement in fitness compared with women in the nonexercise control group,” the team comments.
