Abstract in brief

  • Low-volume high-intensity interval training (HIT) can effectively improve muscle performance, increase mitochondrial biogenesis, and enhance endurance capacity, as shown by improved cycling times and metabolic markers in participants.
  • Biopsies from skeletal muscle show that HIT boosts mitochondrial enzyme activities (like citrate synthase and cytochrome c oxidase), increases mitochondrial-related proteins, and raises levels of PGC1α and SIRT1, all key factors in promoting mitochondrial growth and function.
  • The study suggests that a practical, safer, and more accessible HIT model can induce significant molecular and metabolic adaptations in muscle, highlighting its potential as a viable alternative to traditional endurance training.
