High-intensity interval training (HIT) is characterized by intermittent periods of work and rest and may include work bouts lasting seconds to minutes. HIT has typically been applied to older, diseased, and at-risk populations using longer work intervals (2-4 minutes), whereas more recent definitions of HIT include work intervals of 30 to 60 s. Both traditional endurance training (TET) and HIT exert a peripheral affect increasing the capacity of muscle cells to oxidize substrate via signaling…

High Intensity Resistance Exercise Training vs. High Intensity (Endurance) Interval Training to Fight Cardiometabolic Risk Factors in Overweight Men 30–50 Years Old

The main practical application might be that in general overweight-obese people can freely choose their preferred exercise type (HIIT-END or HIT-RT) to improve their cardiometabolic health, while investing an amount of time that should be feasible for everybody.


: Objectives: To compare the effects of high intensity interval training VS moderate intensity continuous training on the cardiovascular endurance in young healthy females. Method: 30 young healthy

Comparison of training responses and performance adaptations in endurance-trained men and women performing high-intensity interval training

Although HIIT improved cycling performance in men and women, it might not be appropriate to evaluate the effectiveness of HIIT using the same variables for both sexes.

High-intensity Interval Training in the Boundaries of the Severe Domain: Effects on Sprint and Endurance Performance.

Although the improvements in endurance performance were similar, training at IHIGH led to higher gains in WAnT performance than training at 105%CP, and changes in RMS and MPO induced by the training were significantly correlated.

Modified sprint interval training protocols: physiological and psychological responses to 4 weeks of training.

This study effectively demonstrated that the repeated generation of peak speed during brief SIT work bouts sufficiently stimulates adaptive mechanisms promoting increases in aerobic and anaerobic capacity.

Sex Differences in High-Intensity Interval Training–Are HIIT Protocols Interchangeable Between Females and Males?

It is concluded that female- and male-specific HIIT protocols should be established since anthropometric and physiological differences across sexes may affect training performance in real-world settings.

Acute effects of three different circuit weight training protocols on blood lactate, heart rate, and rating of perceived exertion in recreationally active women.

Comparing acute effects of three circuit weight training protocols on blood lactate (BLA), heart rate (HR), and ratings of perceived exertion (RPE) found combined circuit weight-interval training (CWIT) elicited greater RPE than traditional circuit weightTraining (TRAD) at all measures.

Active vs. passive recovery during an aerobic interval training session in well-trained runners

Considering that PR elicited lower perceptual loading for a similar cardiorespiratory response, its use would be preferable, at least, for this type of AIT running sessions.

Monitoring training status with HR measures: do all roads lead to Rome?

This review contends that most of the contradictory findings are related to methodological inconsistencies and/or misinterpretation of the data rather than to limitations of heart rate measures to accurately inform on training status, and provides evidence that measures derived from 5-min recordings of resting and submaximal exercise heart rate are likely the most useful monitoring tools.

Increased physical fitness levels of mountaineering athletes: a study of the effects of high-intensity interval training and oregon circuit training

The purpose of this study was to compare the impact of giving High Intensity Interval Training (HIIT) and Oregon Circuit Training on cardiorespiratory endurance abilities. This study used an

Signaling through AMP-activatedprotein kinase and p38 mitogen-activated protein kinase to PGC-1alpha may explain, in part, the metabolic remodeling induced by HIT, including mitochondrial biogenesis and an increased capacity for glucose and fatty acid oxidation.

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.

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.

Aerobic high-intensity intervals improve VO2max more than moderate training.

High-aerobic intensity endurance interval training is significantly more effective than performing the same total work at either lactate threshold or at 70% HRmax, in improving VO2max.

The effects of high-intensity interval training in well-trained rowers.

Four weeks of HIT improves 2000-m time-trial performance and relative Vo2peak in competitive rowers, more than a traditional approach.

Short‐term sprint interval versus traditional endurance training: similar initial adaptations in human skeletal muscle and exercise performance

Data demonstrate that SIT is a time‐efficient strategy to induce rapid adaptations in skeletal muscle and exercise performance that are comparable to ET in young active men.

Metabolic response of trained and untrained women during high-intensity intermittent cycle exercise.

It is shown that high-intensity intermittent exercise resulted in significant elevations in catecholamines that appear to be related to increased venous glycerol concentrations.

Matched work high-intensity interval and continuous running induce similar increases in PGC-1α mRNA, AMPK, p38, and p53 phosphorylation in human skeletal muscle.

It is demonstrated that acute HIT and CONT running (when matched for average intensity, duration, and work done) induces similar activation of molecular signaling pathways associated with regulation of mitochondrial biogenesis, thus highlighting an additional pathway by which exercise may initiate mitochondrialBiogenesis.

An acute bout of high-intensity interval training increases the nuclear abundance of PGC-1α and activates mitochondrial biogenesis in human skeletal muscle.

Findings support the hypothesis that an acute bout of low-volume HIT activates mitochondrial biogenesis through a mechanism involving increased nuclear abundance of PGC-1α.

Physiological responses to interval training sessions at velocities associated with VO2max.

High intensity, short-duration 2:1 W/R intervals appear to produce responses that may benefit both aerobic and anaerobic energy system development and an upper limit for individuals in the initial phases of interval training is found.
