Sprint interval training (SIT) rapidly increases skeletal muscle GLUT4 and oxidative capacity (COX4) proteins, and these specific adaptations persist for at least 6 weeks after detraining, whereas fatty acid transport proteins remain unchanged.
To boost your muscle's ability to handle glucose and energy production, try Sprint Interval Training (SIT). Perform 4-6 bouts of 30-second all-out cycling, with 4 minutes of rest between each. Do this 3 times a week for 6 weeks. You will likely see significant improvements in your metabolic health markers, and these benefits will stick around even if you take a break from training for a few weeks.
We conclude that short-term SIT induces rapid increases in skeletal muscle oxidative capacity but has divergent effects on proteins associated with glucose, lactate, and fatty acid transport... Muscle GLUT4 content increased after 1 wk of SIT and remained >20% higher compared with baseline during detraining... Muscle oxidative capacity... increased by ~35% after 1 wk of SIT and remained higher... even after 6 wk of detraining.
Why this rating
Randomized controlled design with muscle biopsies, though small sample size (n=6 for biopsy) limits generalizability.
