That’s a dumbbell in her right hand. I work-out with those myself.
I don’t have access to the full scientific report, but I’ve posted part of the abstract below.
The biggest problem with the study at hand is that physical activity apparently was surveyed only at the start of this 14-year study. Results would be much more robust if activity was surveyed every year or two. My overall activity level seems to change every two or three years. How about you?
Moving on.
“Compared to women who reported no strength training, women engaging in any strength training experienced a reduced rate of type 2 diabetes of 30% when controlling for time spent in other activities and other confounders. A risk reduction of 17% was observed for cardiovascular disease among women engaging in strength training. Participation in both strength training and aerobic activity was associated with additional risk reductions for both type 2 diabetes and cardiovascular disease compared to participation in aerobic activity only.
CONCLUSIONS: These data support the inclusion of muscle-strengthening exercises in physical activity regimens for reduced risk of type 2 diabetes and cardiovascular disease, independent of aerobic exercise. Further research is needed to determine the optimum dose and intensity of muscle-strengthening exercises.”
