Abstract in brief

The review investigates how different types of exercise (endurance, high-intensity interval, and sprint interval training) affect mitochondrial content and capillary growth in human skeletal muscle, which are important for aerobic fitness and related to chronic and age-related diseases.
Data from nearly 6,000 participants across multiple studies showed that all exercise types similarly increase mitochondrial content, with percentage improvements around 23-28%, and these effects are not significantly impacted by factors like age, sex, or menopause.
Besides mitochondrial and capillary adaptations, the study also examined changes in VO2max, muscle fiber size, and fiber types, highlighting the comprehensive effects of various training methods on muscle physiology.
