Resistance training has become a mainstay of exercise training in
type 2 diabetes mellitus (T2DM). However, it remains controversial whether
hypertrophy resistance training (HRT) is superior to endurance resistance
training (ERT) with regard to its effects on glycaemic control, muscle mass and
strength. METHODS: Thirty-two patients with T2DM (13 men and 19 women; 64.8 +/-
7.8 years) were randomly assigned to either eight weeks of HRT (n = 16; 2 sets,
10-12 repetitions, 70% of the one-repetition maximum (1-RM)) or ERT (n = 16; 2
sets, 25-30 repetitions, 40% 1-RM). In addition, all patients participated in
aerobic exercise training (AET; 1 hour/day on 2 non-consecutive days/week; cycle
ergometer; 70% of heart rate reserve). RESULTS: After eight weeks of
intervention, there were time but not group effects for reduced glucose and
fructosamine levels, weight, BMI, waist circumference, subcutaneous abdominal
fat, resting heart rate, systolic and diastolic blood pressure; muscle mass of
the arms and physical exercise capacity increased significantly. Significant time
and group effects were documented for maximum strength of the chest, with a
greater increase for HRT than ERT (p = 0.01). CONCLUSIONS: Specific maximal
resistance training of the chest muscles led to superior gain in strength as
compared to endurance resistance training. This, however, did not translate into
superior values of glycaemic control, weight, waist circumference, muscle mass
and physical work capacity, which all improved significantly by a similar
magnitude in both groups. Since overall effects of both protocols were
comparable, both may be offered to patients according to their personal
preference.
