HIIT Workout : The Effective and Efficient Way to Burn Fat

HIIT Workout : The Effective and Efficient Way to Burn Fat. Most training programs designed to promote a decrease in fat levels use activities with low or moderate intensity such as walking and jogging activities. Unfortunately, the results from both kinds of use such activities rarely produce. High Intensity Interval Training (HIIT) workout may be the answer.

A Canadian study led by Angelo Tremblay found that high intensity exercise is superior to moderate-intensity aerobics for fat removal. This study was conducted with two groups of people who practice good 20 weeks of moderate intensity aerobic exercise or 15 weeks of HIIT workout. Aerobic group burned 48 percent more calories than HIIT group during the study. HIIT group decreased fat nine times larger, even though they burn fewer calories during exercise than aerobics group. Besides, groups of HIIT has a resting rate higher than 3-hydroxyacyl coenzyme A dehydrogenase (HADH = function of the proteins encoded in the mitochondrial matrix to catalyze the oxidation chain 3-hydroxyacyl-coa as part of the path of beta oxidation. The enzyme activity is highest the fatty acid) which is an important marker of fat burning.

HIIT workout painful and suffering but paid with a huge advantage. Besides accelerating fat loss, HIIT build fitness, metabolic capacity, and maximal oxygen consumption amazingly fast.

HIIT workout: How does it work?

HIIT program is very diverse, but usually involves short sprints repeatedly with high intensity on the track, treadmill, or bike followed by low intensity workout or rest. This workout routine is not pleasant; The workout is actually very difficult, but the effect of fat disappear faster and leaner midsection.

Hormones such as catecholamines, cortisol, and growth hormone increases during HIIT, contributing to the loss of fat. Fat-burning hormones increase more during HIIT than aerobics, it can explain why HIIT is more effective for fat loss.

Catecholamineis a hormone produced in fat burning during high intensity workouts. Catecholamines, particularly epinephrine, increase the release of fat from both the surface and the supplies of fat in the muscle. These hormones work by binding to receptor beta. Beta receptor density is greater in abdominal fat than fat surface, so that HIIT can increase abdominal fat loss.

A study in 2009 that examined the response to catecholamines from 12 men who completed during the 6 second sprint to 10 repetitions and recovery 30 seconds between each run. From the beginning, the liquid epinephrine increased 6.3-fold, while norepinephrine increased 14.5-fold by the end of the sprint.

HIIT: An Explosion GH (Growth Hormone)

Growth hormone (GH) triggers growth during childhood, but it is also important to build muscles and bones and scrape the fat in adults. HIIT causes the release of growth hormone (GH). Only 30 seconds maximal exercise, growth hormone increased 1000%. It will remain elevated one hour after exercise. Growth hormone (GH) hold the body's primary fat storage is performed by the enzyme lipoprotein lipase (LPL), an enzyme that makes the accumulation of fat beneath the folds of the stomach. Sprint repeatedly led to a decrease in the activity of lipoprotein lipase (LPL) as much as 65 percent in fat cells.

Growth hormone [GH] and Catecholamines: The combination of the Maximum Fat Burning

When the growth hormone (GH) and catecholamines increased from HIIT workout, growth hormone (GH) increased the activity of catecholamines. In the laboratory, the addition of growth hormone (GH) can improve the response of fat cells to epinephrine (a hormone powerful fat burner).

In 2000, researchers studied the response of growth hormone (GH) and catecholamines during and after exercise, from a wide range of intensity and associated with this response to changes in the fat burning effect. Fat burning after exercise associated with the exercise intensity and while it was correlated with both things: the peak of growth hormone (GH) and peak response of epinephrine. Upon further analysis, the peak response of growth hormone (GH) is the best predictor of post-exercise fat utilization.

HIIT Workout Burn More Fat in the Lower Skin

HIIT will burn more fat than ordinary walking on the treadmill, comparing HIIT and aerobic exercise, after 24 weeks, subjects in the HIIT group lost fat under the skin more, as measured by skin folds.

Another study conducted on HIIT program for 15 weeks with three weekly sessions of 20 minutes of HIIT. HIIT cycles, consisting of sprint 8 seconds followed by 12 seconds of low intensity. Another group performed aerobic cycles program consisting of a stable cycles with 60 percent of VO2max for 40 minutes. The results showed that the HIIT group lost more fat level (2.5 kg) than the aerobic group.

If you want to shrink the several layers of abdominal fat, try interval training. Why waste time with low intensity walking program, when you can shape the abdomen in a short time?
