Our aim was to examine the effects of seven high-intensity aerobic interval training (HIIT) sessions over 2 wk on skeletal muscle fuel content, mitochondrial enzyme activities, fatty acid transport proteins, peak O(2) consumption (Vo(2 peak)), and whole body metabolic, hormonal, and cardiovascular responses to exercise. Eight women (22.1 +/- 0.2 yr old, 65.0 +/- 2.2 kg body wt, 2.36 +/- 0.24 l/min Vo(2 peak)) performed a Vo(2 peak) test and a 60-min cycling trial at approximately 60% Vo(2 peak… Expand
High-intensity aerobic interval training increases fat and carbohydrate metabolic capacities in human skeletal muscle.
TLDR
This study demonstrated that 18 h of repeated high-intensity exercise sessions over 6 weeks (3 d.week-1) is a powerful method to increase whole-body and skeletal muscle capacities to oxidize fat and carbohydrate in previously untrained individuals. Expand
Effect of two doses of interval training on maximal fat oxidation in sedentary women.
TLDR
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. Expand
Effect of training in the fasted state on metabolic responses during exercise with carbohydrate intake.
TLDR
Although there was a decrease in exercise-induced glycogen breakdown and an increase in proteins involved in fat handling after fasting training, fat oxidation during exercise with carbohydrate intake was not changed and fat oxidation rates during exercise were not altered by training. Expand
Re-examination of the contribution of substrates to energy expenditure during high-intensity intermittent exercise in endurance athletes
TLDR
The present study indicates that 17 times more fat oxidation was measured in the athlete group compared to the untrained group, however, the athletes had the same CHO oxidation rate as the recreationally active subjects during high-intensity intermittent exercise. Expand
Effect of high-intensity interval exercise on lipid oxidation during postexercise recovery.
TLDR
Findings show that lipid oxidation during postexercise recovery was increased by a similar amount on two isoenergetic exercise bouts of different forms and intensities compared with the time-matched no-exercise control trial. Expand
Two Weeks of Interval Training Enhances Fat Oxidation during Exercise in Obese Adults with Prediabetes.
TLDR
High intensity INT training enhancesFat oxidation during the same relative intensity exercise in people with prediabetes is enhanced and correlated with increased VO2peak. Expand
Effect of interval training intensity on fat oxidation, blood lactate and the rate of perceived exertion in obese men
TLDR
Interval training can increase fat oxidation with no effect of exercise intensity, but BLa and RPE decreased after HIIT to greater extent than MIIT. Expand
Magnitude and time course of changes in maximal oxygen uptake in response to distinct regimens of chronic interval training in sedentary women
TLDR
It is demonstrated that a relatively prolonged regimen of moderate or more intense interval training induces similar improvements in cardiorespiratory fitness, although HI induced greater increases in VO2max early on in training than LO. Expand
Effects of high-intensity interval training on cardiometabolic risk factors in overweight/obese women
TLDR
Short-term interval exercise training may be effective for decreasing FM and improving exercise tolerance in overweight and obese women. Expand
An acute bout of endurance exercise but not sprint interval exercise enhances insulin sensitivity.
TLDR
It is demonstrated that an acute bout of EE, but not SIE, increases insulin sensitivity relative to a no-exercise control condition in healthy males and females and underscores the use of regular EE as an effective intervention strategy against insulin resistance. Expand

Adaptations in skeletal muscle exercise metabolism to a sustained session of heavy intermittent exercise.
TLDR
Findings are consistent with other studies, namely, that muscle metabolic adaptations to regular exercise are an early adaptive event that occurs before increases in oxidative potential. Expand
Initial aerobic power does not alter muscle metabolic adaptations to short-term training.
TLDR
It is demonstrated that metabolic adaptations to prolonged exercise occur within the first 3 days of training and during the non-steady-state period, and neither time course nor magnitude of metabolic adaptations appears to depend on increases in mitochondrial potential or on initial aerobic power. Expand
Effect of gender on lipid kinetics during endurance exercise of moderate intensity in untrained subjects.
TLDR
It is concluded that lipolysis of adipose tissue triglycerides during moderate-intensity exercise is greater in women than in men, who are matched on adiposity and fitness. Expand
The effect of a 3-month low-intensity endurance training program on fat oxidation and acetyl-CoA carboxylase-2 expression.
TLDR
A minimal amount of physical activity tends to increase fat oxidation and leads to marked changes in the expression of genes encoding for key enzymes in fat metabolism. Expand
Six sessions of sprint interval training increases muscle oxidative potential and cycle endurance capacity in humans.
TLDR
It is concluded that short sprint interval training (approximately 15 min of intense exercise over 2 wk) increased muscle oxidative potential and doubled endurance capacity during intense aerobic cycling in recreationally active individuals. Expand
Skeletal muscle buffering capacity and endurance performance after high-intensity interval training by well-trained cyclists
TLDR
The results indicate that βm may be an important determinant of relatively short-duration (< 60 min) endurance cycling activity and responds positively to just six sessions of high-intensity, submaximal interval training. Expand
Effect of short-term sprint interval training on human skeletal muscle carbohydrate metabolism during exercise and time-trial performance.
TLDR
It is concluded that short-term SIT improved cycling TT performance and resulted in a closer matching of glycogenolytic flux and pyruvate oxidation during submaximal exercise. Expand
Muscle performance and enzymatic adaptations to sprint interval training.
TLDR
It was concluded that relatively brief but intense sprint training can result in an increase in both glycolytic and oxidative enzyme activity, maximum short-term power output, and VO2 max. Expand
Substrate utilization during endurance exercise in men and women after endurance training.
TLDR
It is concluded that females oxidize proportionately more lipid and less carbohydrate during exercise compared with males both pre- and posttraining, which was cotemporal with a higher glycerol R(a) in females. Expand
Progressive effect of endurance training on metabolic adaptations in working skeletal muscle.
TLDR
The results show that a period of short-term training results in many characteristic training adaptations but that these adaptations occurred before increases in mitochondrial potential, which were linked to the increase in muscle mitochondrial capacity. Expand
