One resistance-trained man performed blood-flow-restricted leg exercise at 30 percent 1RM on one leg and normal exercise at 70 percent 1RM on the other. Muscle biopsies were compared by electron microscopy before and 30 minutes after exercise. BFR produced longer sarcomeres and wave-like myofibril changes with pockets of sarcoplasm, consistent with fluid pooling and fiber swelling. No ketone supplement was part of this study.
