PURPOSE The present study compared the effects of aerobic endurance training at different intensities and with different methods matched for total work and frequency. [] Key Method All four training protocols resulted in similar total oxygen consumption and were performed 3 d.wk for 8 wk. RESULTS High-intensity aerobic interval training resulted in significantly increased VO2max compared with long slow distance and lactate-threshold training intensities (P<0.01).

Figures and Tables from this paper

Effect of intensity of aerobic training on VO2max.

When volume of exercise is controlled, higher intensities of exercise are more effective for improving VO2max than lower intensitiesof exercise in healthy, young adults.

Low- and High-Volume of Intensive Endurance Training Significantly Improves Maximal Oxygen Uptake after 10-Weeks of Training in Healthy Men

The data suggest that a single bout of AIT performed three times per week may be a time-efficient strategy to improve VO2max and reduce blood pressure and fasting glucose in previously inactive but otherwise healthy middle-aged individuals.

The Effects of High Intensity Interval Training vs Steady State Training on Aerobic and Anaerobic Capacity.

Although HIIT protocols are time efficient, they are not superior to conventional exercise training in sedentary young adults, and enjoyment of training decreases across the course of an 8 week experimental training program.

Physiological Adaptations to Sprint Interval Training with Matched Exercise Volume

The higher incremental aerobic performance and lower skinfold thickness in HIIT 60s versus HIIT10s reflected similar adaptations, but the higher repeated sprint performance was observed only in responses to HIIT60s, which may elicit greater anaerobic adaptations.

Overspeed HIIT in Lower-Body Positive Pressure Treadmill Improves Running Performance.

A 4-wk HIIT protocol at 100% vVO2max improves field performance, vVO 2max, VO2max and submaximal HR in trained runners and could provide an alternative for taxing HIIT sessions.

The Effects of High-Intensity Interval Training versus Moderate-Intensity Continuous Training on Maximal Oxygen Uptake in Sedentary Adults

8 weeks of low-volume HIIT & 8 weeks of high-volume MICT led to increases in VO2max that did not differ significantly in 24 sedentary adults, and VO2 max increased significantly in all participants after the interventions.

It is indicated that HICR can be equally performance enhancing as MICR, non-matched for total work, in recreational athletes, and can increase maximal aerobic power, whereas MICR may enhance fat oxidation.

Magnitude and time course of changes in maximal oxygen uptake in response to distinct regimens of chronic interval training in sedentary women

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.

HIIT vs moderate intensity endurance training: impact on aerobic parameters in young adult men

HIIT was more effective for improving rVO2max and vVO2 max than CT+HIIT in healthy, young adults.



The effect of interval and continuous training on the aerobic parameters.

There were no between-group differences; thus neither low power output nor high power output interval training offers an advantage over continuous training of the same average power output in altering the aerobic parameters.

Improved running economy following intensified training correlates with reduced ventilatory demands.

Recreational runners can improve RE and aerobic run performance by exchanging parts of their conventional aerobic distance training with intensive distance or long-interval running, whereas short-intervals running is less efficient.

It was concluded that the higher VO2max and Than in the men was compensated for by more running, superior CR, and a higher exercise intensity during the race in the performance-matched female marathon runners.

Effects of different running programs on VO2 max, percent fat, and plasma lipids.

It is indicated that interval training may benefit aerobic capacity more than continuous running in young adults who have moderately high initial fitness levels and cardiovascular fitness parameters are not easily altered by short term exercise in young active men and women.

Maximal strength training improves aerobic endurance performance

Maximal strength training with emphasis on neural adaptations improves strength, particularly rate of force development, and improves aerobic endurance performance by improved work economy.

Aerobic endurance training improves soccer performance.

Enhanced aerobic endurance in soccer players improved soccer performance by increasing the distance covered, enhancing work intensity, and increasing the number of sprints and involvements with the ball during a match.

Sex differences in performance-matched marathon runners

Apart from the well-known variation in height and differences in the percentage of fat, the difference between performance-matched male and female marathon runners seemed primarily to be found in running economy and amount of training.

Effects of low intensity aerobic training on skeletal muscle capillary and blood lipoprotein profiles.

It is indicated that low intensity training increases capillary density in skeletal muscle, which may explain in part the changes in the lipoprotein profiles.

Effect of training intensity on muscle lactate transporters and lactate threshold of cross-country skiers.

The training response differed between MIG and HIG both in terms of performance and of the effect on MCT1, which may be important for releasing lactate to the blood during long-lasting exercise.

The Interactions of Intensity, Frequency and Duration of Exercise Training in Altering Cardiorespiratory Fitness

Although these pooled data suggest that maximal gains in aerobic power are elicited with intensities between 90 to 100% V̇O2 max, 4 times per week with exercise durations of 35 to 45 minutes, it is important to note that lower intensities still produce effective changes and reduce the risks of injury in non-athletic groups.
