Evidence suggests that sprint interval training (SIT) is a time efficient alternative for improving aerobic fitness or insulin sensitivity due to its reduced training volume and is of increasing interest since most sedentary individuals indicate lack of time as their number one barrier to being physically active. [] Key Method The R-SIT group (n=5) completed 4-10 bouts of 30s “all out” sprints on a motorized treadmill at a 3-5% incline with 4 min active recovery.



Effect of 2 weeks of sprint interval training on health-related outcomes in sedentary overweight/obese men.

Running sprint interval training induces fat loss in women.

Running SIT is a time-efficient strategy for decreasing body fat while increasing aerobic capacity, peak running speed, and fat-free mass in healthy young women.

Low-volume interval training improves muscle oxidative capacity in sedentary adults.

Constant-load low-volume HIT may be a practical time-efficient strategy to induce metabolic adaptations that reduce the risk for inactivity-related disorders in previously sedentary middle-aged adults.

Similar Health Benefits of Endurance and High-Intensity Interval Training in Obese Children

HIT and ET were equally effective in improving important health related parameters in obese youth and revealed a very similar pattern of the most responsive variables among groups.

Sprint interval and traditional endurance training induce similar improvements in peripheral arterial stiffness and flow-mediated dilation in healthy humans.

It is concluded that SIT is a time-efficient strategy to elicit improvements in peripheral vascular structure and function that are comparable to ET, however, alterations in central artery distensibility may require a longer training stimuli and/or greater initial vascular stiffness than observed in this group of healthy subjects.

Effect of two doses of interval training on maximal fat oxidation in sedentary women.

It is suggested that 12 wk of either moderate or more strenuous interval training similarly enhance fat oxidation in sedentary women but do not alter body weight or body composition.

Two minutes of sprint-interval exercise elicits 24-hr oxygen consumption similar to that of 30 min of continuous endurance exercise.

Despite large differences in exercise VO₂, the protracted effects of SIE result in a similar total VO⁂ over 24 hr vs. CEE, indicating that the significant body-fat losses observed previously with SIT are partially due to increases in metabolism postexercise.

Towards the minimal amount of exercise for improving metabolic health: beneficial effects of reduced-exertion high-intensity interval training

It is shown that a novel, feasible exercise intervention can improve metabolic health and aerobic capacity and REHIT may offer a genuinely time-efficient alternative to HIT and conventional cardiorespiratory exercise training for improving risk factors of T2D.

Similar metabolic adaptations during exercise after low volume sprint interval and traditional endurance training in humans

Given the markedly lower training volume in the SIT group, these data suggest that high‐intensity interval training is a time‐efficient strategy to increase skeletal muscle oxidative capacity and induce specific metabolic adaptations during exercise that are comparable to traditional ET.
