High Intensity Resistance Training Improves Glycemic
Control in Older Patients with Type 2 Diabetes
By Chris Defeyter and Ashlie Sklenicka
Type 2 Diabetes Type 2 diabetes is when your body
doesn’t use insulin properly. At first your pancreas makes extra
insulin to make up for it and over time it isn’t able to keep up and can’t make enough to keep your blood glucose levels normal.
Why we chose this topic? Little is known about the impact of
resistance training and diabetes The regimen for improving the
metabolic profile with resistance training of older patients with type two diabetes seemed interesting.
Diabetes is a growing problem in the US in all ages.
Characteristics of Population Men and women ages 60-80 with type 2
diabetes Subjects were overweight, sedentary, were
not taking insulin, and nonsmokers. 110 potential volunteers were invited to
attend a 6 month clinical trial Out of the 110 volunteers 47 were taken
and 36 agreed to do the tests. After exclusions 29 were allowed to do the testings with an ending drop out rate of 19%
Exclusions History or physical findings of ischemic
heart disease Systemic diseases Uncontrolled hypertension Advanced diabetic neuropathy or
retinopathy. Subjects with severe orthopedic,
cardiovascular or respiratory conditions 6 people dropped out of the study after 8
weeks
Hypothesis The aim of this randomized controlled
trial was to examine the effects of a 6 month high- intensity progressive resistance training program, combined with a healthy eating designed to elicit moderate weight loss, on HbA1c and body composition in older adults with type 2 diabetes.
Testing of Hypothesis 6-month randomized controlled clinical trail
with repeated measurements performed at 3 month intervals. Subjects were randomly assigned to either a high- intensity progressive resistance training plus moderate weight loss group.
There was a resistance training and weight loss group and a control group that was just on a weight loss group.
Used specific machines that tested HbA1c levels in the patients.
Sessions 3 times per week on nonconsecutive
days 5 min warm up and cool down of low
intensity stationary cycling and a 45 minute of high-intensity resistance training
Goal: to achieve between 75 and 85% of the current 1-RM.
Sessions Progressive resistance
training program used free weights and a multiple-station weight machine.
Used 3 sets of 8-10 reps Training increased
regularly as tolerated for each muscle group and 1RM was reestablished every 12 weeks.
Used 9 different exercises
Bench press Leg extensions Upright row Lateral pull downs Standing leg curl Dumbbell seated
shoulder press Dumbbell seated
bicep curls Dumbbell triceps
kickbacks Abdominal curls
Results HbA1c: In the RT and WL program had a
significant reduction in HbA1c at 3 and 6 months
There was no change for the WL group In body composition and changes in
Anthropometic there was a significant reduction for both RT and WL and the WL groups
Expected muscle strength increased in RT and WL but no in the WL group
Conclusion The reduction in the HbA1c after
resistance training is likely to offer a prognostic advantage in older patients with type 2 diabetes.
Patients with type 2 diabetes have reported improved insulin sensitivity.
FITT recommendations Frequency: 3-7days/ week Intensity: 40%-60% of VO2R Time: 150 min/ week Type: Emphasize activities that use
large muscle groups in a rhythmic and continuous fashion.
Special considerations Hypoglycemia is the most serious problem
for individuals with DM who exercise Blood glucose monitoring before and for
several hours following exercise The timing of exercise: using insulin,
changing insulin timing, reducing insulin dose.
Physical activity combined with oral hypoglycemic agents haven’t been studied and little is known about potential interactions.
