Blood-flow restriction resistance training improves skeletal muscle mitochondrial oxidative capacity and cardiovascular risk factors in type 2 diabetes
Listed in NCBI GEO
Impaired muscle strength and mitochondrial functionality are hallmarks of type 2 diabetes (T2D).
Description
Conventional combined resistance/endurance exercise training has limited efficacy to simultaneously improve muscle function and metabolism. We examined whether low-load blood flow restriction training (BFRT) increases both muscle strength and mitochondrial oxidative capacity in T2D.
Over 12 weeks, BFRT and conventional resistance training (CREST) similarly improved muscle strength despite lower workload in BFRT. Uniquely, BFRT enhanced muscle and adipose tissue oxidative capacity and increased muscle mitochondrial content. Transcriptomic profiling revealed more pronounced changes, particularly in angiogenesis-linked pathways, upon BFRT.

BFRT also preferentially led to reductions in visceral adipose tissue volume and waist circumference, whereas CREST more effectively decreased subcutaneous adipose tissue volume. Both interventions lowered resting heart rate and diastolic blood pressure. These findings position BFRT as promising low-load exercising strategy to simultaneously improve mitochondrial oxidative capacity, muscle strength and body composition in individuals with T2D.
