PURPOSE: Gain in strength is a level A recommendation for treatment of type-2 diabetes mellitus (DM). Vibration training resulted in gain in strength. Metabolic effects in DM-patients have rarely been investigated. Aim: To compare the effects of strength and vibration training on metabolism in DM. METHODS: A group of 22 female type-2-diabetes, mean age 65 years, agreed to participate in a training intervention study, 7 for strength training (BMI 25 kg/m2), 7 for vibration training (BMI 30 kg/m2) and 8 for controls (BMI 31 kg/m2). Each training session lasted 30 minutes, conducted twice a week over 12 weeks. Knee isometric strength of flexion and extension were measured. Shoulder training, lumbar extension and flexion before and after training, glucose, HbA1c, cholesterol, triglycerides, HDL and LDL after overnight fasting and a glucose tolerance test. RESULTS: BMI remained constant. Knee extension and flexion increased in both intervention groups, also shoulder strength and the strength of the lumbar extensors and flexors. HbA1c dropped from 6.7 to 6.4 % (p<0,05) in the vibration and from 6.8 to 6.2 % (p<0,05) in the strength training group. HDL increased from 52 to 59 mg/dl (p<0,05) in the strength training group. Also, the area under the glucose tolerance curve regressed in both groups. No changes of LDL, cholesterol, triglycerides and fasting glucose and none at all in the control group. CONCLUSIONS: <BRVibration training may be recommended as well as strength training for improving glycemic parameters in DM women.
