A few minutes of high-intensity interval (HIIT) or sprinting exercise may be as effective as much longer exercise sessions in spurring beneficial improvements in mitochondrial function, according to new research. The small study is published ahead of print in the American Journal of Physiology — Regulatory, Integrative and Comparative Physiology.
The report explains, “Mitochondria, the energy centers of the cells, are essential for good health. Previous research has found that exercise creates new mitochondria and improves the function of existing mitochondria. Altered mitochondrial function in response to a single session of exercise generates signals that may lead to beneficial changes in the cells, lowering the risk for chronic disease. High-intensity interval exercise consists of short bursts of high-intensity aerobic exercise — physical activity that raises the heart rate — alternating with brief recovery periods. Whether the intensity of a workout affects mitochondrial response is unclear.”
HIIT training is a great way to get your strength sessions and aerobic exercise at the same time. Super-efficient HIIT is the ideal workout for a busy schedule—whether you want to squeeze in a workout during your lunch break or to get in shape for a fast-approaching event. Research shows you can achieve more progress in a mere 15 minutes of interval training (done three times a week) than jogging on a treadmill for an hour. And according to a 2011 study presented at the American College of Sports Medicine Annual Meeting, just 2 weeks of high-intensity intervals improves your aerobic capacity as much as 6 to 8 weeks of endurance training.
