Resistance
Exercise Improves Glycemic Control in Older Diabetic Patients
A
program of high-intensity progressive resistance training (PRT)
improves glycemic control and metabolic abnormalities in older
patients with type 2 diabetes.
In
a 16-week, randomized, controlled study, Dr. Carmen Castaneda and
colleagues from Tufts University, Boston, Massachusetts, assigned 62
patients (mean age 66 years) with type 2 diabetes to supervised PRT or
to a control group. The exercise intervention consisted of three
sessions a week in which the subjects performed three sets of eight
repetitions on five pneumatic resistance training machines. Intensity
progressively increased during the program.
Plasma
glycosylated hemoglobin levels decreased from 8.7% to 7.6% in patients
randomized to PRT, and muscle glycogen stores increased from 60.3 to
79.1 mmol glucose/kg muscle. In addition, 72% of patients in this
group had a reduction in the dose of prescribed diabetes medication.
There
was no change in glycosylated hemoglobin among control patients, while
muscle glycogen decreased from 61.4 to 47.2 mmol glucose/kg. Also,
there was a 42% increase in prescribed diabetes medications.
PRT
subjects versus control subjects also increased in lean mass (+1.2
versus -0.1 kg), reduced systolic blood pressure (-9.7 versus +7.7 mm
Hg), and decreased trunk fat mass (-0.7 versus +0.8 kg ), Dr.
Castaneda reported.
They
conclude that "appropriately prescribed and supervised" high
intensity resistance exercise training is feasible and beneficial for
older type 2 diabetics. Diabetes
