NCT04222231

Brief Summary

The study aims to investigate the metabolic and cardiovascular effects of classical resistance training with high loads and blood-flow restricted training (BFRT) with low loads in individuals with type 2 diabetes over 12 weeks.

Outcome Measures

Primary Outcomes (1)

  • Change in insulin sensitivity by blood-flow restriction or classical resistance training

    By using hyperinsulinemic-euglycemic clamp technique, changes in the M-value (mg x kg-1 x min-1) will be measured. The m-value represent the glucose infusion rate at a defined level of hyperinsulinemia during a glucose clamp test. The hyperinsulinemic-euglycemic clamp technique will thus be implicated to assess changes in insulin sensitivity before and after 12 weeks of resistance training.

    Before and after 12 weeks of training (intervention)

Secondary Outcomes (1)

  • Changes in skeletal muscle mass by blood-flow restriction or classical resistance training

    Before and after 12 weeks of training (intervention)

Other Outcomes (1)

  • Changes in skeletal muscle strength by blood-flow restriction or classical resistance training

    Before and after 12 weeks of training (intervention)

Study Arms (2)

Blood-flow restriction resistance training

EXPERIMENTAL

Resistance training with low loads (15-30% RM) in combination with a brief occlusion of venous blood flow using a tourniquet while exercising.

Other: Blood-flow restriction resistance training

Classical resistance training

EXPERIMENTAL

Resistance training with high loads (60-80% RM).

Other: Classical resistance training

Interventions

Training program: After 10 minutes of warm-up the participant performs three exercises with BFRT for the lower extremities. The intensity is about 15-30% of 1-RM.

Blood-flow restriction resistance training

Training program: After warm-up the participant performs three exercises for lower body. The intensity is about 60-80% of 1-RM.

Classical resistance training
