Inspired by the principles propounded by the German coach Sports and high-intensity training university professor Woldemar Gerschler and the Swedish physiologist Per-Olof Åstrand trainimg, Coe hhigh-intensity sessions high-intensty repeated fast meter runs with only 30 seconds recovery between each fast run.

A version of HIIT is based on a study [18] by Ritsumeikan University Professor Izumi Tabata 田畑泉 et al. initially involving Olympic speedskaters.

The exercise was performed on a mechanically braked cycle Robust Orange Essence. Tabata called this the High-inhensity protocol. However traaining Tabata high-lntensity had achieved comparable aerobic improvements Robust Orange Essence only exercised 4 minutes per day traihing their 4 HIIT days compared to high-intenzity minutes for the aerobic group.

Also, only the Tabata group had gained anaerobic capacity benefits. As High-inteneity protocol is "supermaximal", [12] his Weight loss and cardiovascular health technically falls Sportss Robust Orange Essence high-intenslty of SIT.

Professor Martin Gibala and his high-inteensity at McMaster University in Canada have been researching high-intensity exercise for several years. While still a demanding form of training, the general public could use this exercise Hydrating gel masks with nothing more than an average exercise bike.

This was intended as a gentler option for sedentary Refreshment Packages for Meetings who had done no exercise for over a year. In Jorge Zuniga, assistant professor of exercise science at Creighton Universityset out to determine how to fit the highest volume of work and oxygen consumption into the smallest amount of time.

Zuniga's protocol has been implemented with great success by students of his who were participating in Creighton's Army ROTC program. Cadets completing the protocol twice a week saw greater improvements in APFT scores than in years past.

Dr Niels Vollaard at the University of Stirling proposed that when high-intensity intervals are done at "all-out" intensities, associated health benefits plateau after performing 2 or 3 sprint repetitions. This led to the development of a minute exercise routine consisting of easy pedalling interspersed with two second "all-out" cycling sprints.

He shifted the terminology for his to SIT. In a BBC Horizon program in FebruaryJamie Timmons, professor of systems biology at the University of Loughboroughled Michael Mosley through this exercise bike regimen, each time using three sprints instead of two.

This protocol was performed three times a week for a total of 30 minutes of exercise per week 3 minutes of intense exerciseplus warm-up and recovery time. Its conclusion was "HIIT is the recommended routine" but "the magnitude of differences in various parameters between regimens was small; therefore, preference for either modality may be up to the individual".

HIIT training and traditional endurance training both lead to significantly improved cardiovascular fitness in healthy adults ages 18—45 but HIIT leads to greater improvements in VO 2 max. Comparing HIIT to moderate intensity continuous training MICT in people with coronary artery diseaseHIIT leads to greater improvements in VO 2 max but MICT leads to greater reductions in body weight and heart rate.

For people suffering from coronary artery disease or heart failurea HIIT regimen is beneficial for substantially improving both groups VO 2 max and overall exercise capacity; with more intense HIIT leading to the greatest cardiovascular improvements.

HIIT significantly lowers insulin resistance compared to continuous training or control conditions and leads to modestly decreased fasting blood glucose levels and increased weight loss compared to those who do not undergo a physical activity intervention.

HIIT can result in modest reductions of subcutaneous fat in young and healthy individuals, but greater reductions for overweight individuals. A systematic review examined the effects of HIIT combined with resistance training in teens ages 10—19without providing a nutritional plan.

The study found that 8 to 12 weeks of HIIT combined with resistance training can substantially reduce waist size and body fat percentage. However the study did not find conclusive evidence of HIIT and resistance training being an effective solitary treatment for type 2 diabetes or arterial hypertensionbut did find HIIT has the potential to reduce future cardiovascular problems in teens.

HIIT can elicit short term brain improvements similar to those usually observed with aerobic exercise. The American College of Sports Medicine suggests consulting one's doctor before starting a HIIT regimen, particularly if there is a history of coronary heart disease.

This is to ascertain its safety and allow the patient to build up the intensity of exercise without causing harm. There is a risk of injury due to fatigue and overtrainingso it is advised to allow time for recovery.

More specifically, knee and ankle sprains were very common. Based on that, neuromuscular training and pre-strengthening programs are recommended to improve flexibilityparticularly before exercise. A study examined HIIT's physiological effects on fat oxidation in moderately active women.

The study found that seven sessions of HIIT over a 2-week period improved whole body fat oxidation and the capacity for skeletal muscle to oxidize fat in moderately active women. A study examined the effect of HIIT on cognitive performance among a group of children.

The authors show that HIIT is beneficial to cognitive control and working memory capacity when compared against "a blend of board games, computer games, and trivia quizzes" and that this effect is mediated by the BDNF polymorphism. They conclude that the study "suggests a promising alternative to enhance cognition, via short and potent exercise regimens".

A clinical trial assessed the effects of HIIT on vascular health in inactive people and found that HIIT has beneficial vascular effects, based on observed decreases in arterial wall thickness and increase in endothelial function.

The trial also found that HIIT had stronger effects than medium intensity continuous training MICT in enhancing flow mediated dilation and lowering pulse wave velocity in inactive adults from the greater blood flow and vasodilation of blood vessels stimulated by HIIT.

Increased flow mediated dilation allows for greater opening of an artery and increased blood flow, allowing for more oxygen to be supplied throughout the body during activity. Pulse wave velocity is used to monitor arterial stiffness ; which increases with age and high blood pressure, leading to a higher probability of cardiovascular problems including hypertension or a stroke.

A study on the relevance of exercise intensity in lower back rehabilitation, demonstrated higher intensity had a greater effectiveness with back therapy than moderate intensity exercise. Participants in the HIIT group had a decrease in back pain intensity and an increase in back muscle strength.

A study examined the impact of HIIT and moderate intensity continuous training MICT on overweight individuals by measuring the effect on cardiorespiratory fitness CRF. The study found that both forms of training were effective in improving CRF with an increase in VO 2 max, however there was no evidence that either training method was more effective than the other in improving cardiorespiratory fitness.

According to a study HIIT could be used as prehabilitation for men awaiting surgery for urological cancer and it may improve heart and lung fitness within a month before their surgery.

A Perspective on High-Intensity Interval Training for Performance and Health | Sports Medicine	This categorization of HIIT is primarily encompassed by the classification of vigorous intensity. Polarized vs. Programming Interval Training to Optimize Time-Trial Performance: A Systematic Review and Meta-Analysis Article 07 April Millet GP, Candau R, Fattori P, Bignet F, Varray A. Int J Environ Res Public Health. Table 2 Research output Full size table.
Key Points	Training intensity as a concept may sound quite ambiguous. The best and most precise way to see how your body responds to training intensity is to take blood samples before, throughout and after the session to determine the level of lactate. That correlates to heart rate Zones 4 and 5. A much easier and more convenient way to measure training intensity is to use heart rate as a guide. The higher the training intensity the faster the heart beats, moving the blood to muscles. Exercise heart rate zones categorize every intensity level and provide a very easy framework to follow during the training session. Related: Train Smart — A Practical Guide to Exercise Heart Rate Zones. More experience athletes would also benefit from using speed or power to measure their exercise intensity. Unfortunately, it does not account for decreased performance caused by accumulated fatigue or illness. So, in this case knowing your body, how it responds to stress and when to back off is critical. Bottom line is, whichever way athletes prefer to measure training intensity, the most important thing is that they actually do. Knowing exactly how hard you train serves as a reference point and allows to take the most of every session. While low intensity training can require as little as simple refueling, high intensity training HIT may require several days before body is ready to train again. In addition to burning glycogen stores, HIT creates bigger micro traumas in the muscle tissue that take a while to heal. At high intensity blood glucose is converted into pyruvic acid that is then converted into energy and lactic acid as a side product. What happens after makes all the difference. Accumulation of these molecules lead to decrease in performance and speed. High intensity training is done in intervals to avoid accumulating too much fatigue at once. Related: How To Measure Post Workout Recovery And Avoid Accumulated Fatigue. If he consumes enough nutrition, of course. The worst possible thing an athlete can do for endurance is to allow the muscles to reach exhaustion. Overloaded with these molecules, mitochondria are forced to work extra hard to utilize them. This even leads to the burnout of some of them, causing loss of endurance. So, all that hard work to build endurance goes to waste. I got this wrong for myself for too long. Are you aiming to become a resilient athlete who is able to withstand any pressure? Be able to jump on any opportunity? Take any challenge life throws at you head on? On the other hand, focus only on low intensity work does improve endurance a lot, but will do little to improve top end speed. If we take into account all what athletes do, they spend vast majority of time at low intensity, focusing on general endurance and strength, technique, flexibility, tactics and other skills. Apart from recovery and endurance benefits, lots of consistent low intensity training also helps athletes build mind-body connection. Repeating a movement over and over for thousands of times improves and optimizes the form and helps to build supportive tissues, which then translates into muscle economy at higher intensities. Not to mention that low intensity helps to improve muscle efficiency and speed up recovery process, allowing athletes to tolerate bigger training load and improve even more. In reality, athletes do a lot of polarized training when they focus on very short but very hard efforts several seconds to several minutes or long and easy efforts half an hour and longer. Balancing the overall training load is a form of art. It is really tricky to get that training intensity just right, to have a significant improvement, but avoid over training. Of course this ratio will vary from session to session or even from week to week. As long as over prolonged period of time several weeks to a month it totals to , the training plan will be balanced and athlete will have enough energy to recover and go hard where needed. Specific split between each of the training zones will depend on the training phase and the goal race distance. Closer to race day, however, athletes may spend more time doing high intensity training to reach the most optimal condition for the race. What is your experience with training intensity? Have you got yourself over trained or in peak condition at exactly the right time? examining the cardiovascular risk of HIIT in coronary heart disease patients, both HIIT and moderate-intensity training exhibited a low risk. However, Halle suggests that the data presented by Rognmo et al. should be interpreted with caution because the rates of cardiovascular complications calculated to the number of patient exercise hours were more than five times higher during HIIT. As such, the risks of adverse effects from HIIT may outweigh the benefits for some clinical populations. To avoid contraindications to HIIT, Weston et al. suggest that careful screening must be conducted when working with clinical populations to ensure that HIIT is used in a safe and appropriate fashion. Potential contraindications to HIIT include the following:. Regardless of the population using HIIT, it is necessary to use a testing method that allows interval training to be programmed. Classically, intense interval training has been programmed based on maximal aerobic speed MAS ,which is the lowest speed that elicits O 2 max and is typically determined via gas exchange analysis. Traditionally composed of shuttle runs, these tests often incorporate accelerations, decelerations, and changes of direction, which reflect the demands associated with many intermittent sports but also can enhance peripheral aspects of cardiorespiratory function. To make these tests more practical, numerous field-based tests have been developed to determine the MAS and indirectly reflect O 2 max. Typically, these tests are based on continuous linear runs or shuttle tests and are used to determine the maximal running speed MRS , which is similar to the MAS, at the end of the test. However, as noted by Buchheit, these tests determine the MRS via efforts that are fundamentally different from intermittent sports, the methods typically used to develop individualized HIIT training programs, and the physiological determinants of performance associated with intermittent or shuttle test efforts. Careful inspection of the scientific and applied literature suggests that the most effective test protocol for evaluating this type of endurance needs to allow the simultaneous inclusion of intermittent and shuttle runs. Two intermittent tests that are often used by practitioners are the interval shuttle run test ISRT and the Yo-Yo test. Although these tests are commonly performed, they only provide an index of intermittent aerobic performance and do not yield an MRS that can be used for developing HIIT programs. To address the inability of these tests to yield an MRS that could be used for programming, Buchheit developed the Intermittent Fitness Test IFTm ,which is tested on a 40 m field. The test has been modified to be performed on a 28 m court and is called the Intermittent Fitness Test IFTm. The strength of this test is that it incorporates physiological variables similar to those seen in interval training, including explosive expressions of power when changing directions, aerobic qualities, and the ability to recover between efforts. This is accomplished by simultaneously using aspects of intermittent and shuttle tests to establish an MRS.

It elicits numerous stamina-friendly physiological adaptations including increasing your ability to burn fat and preserve precious glycogen stores. It is not unusual for age group triathletes to rack-up 20 hours per week of training while balancing family and a full-time job. It can lead to strong results on the race circuit but inevitably squeezes other facets of life. This is why new research into high-intensity training is fascinating—the idea being that you can significantly cut your training volume without letting your performance standards drop. For example, forty-one elite swimmers were studied over a week period during their competitive mid-season with each arbitrarily assigned to one of two groups:. GROUP 1 Twenty swimmers followed a high-intensity interval protocol. However, their high-intensity workload grew to five hours each week. These intervals were broken down as six to 10 intervals of seconds with minutes rest in-between. Weekly training distance amounted to 17km. GROUP 2 Twenty-one swimmers in the control group maintained their existing programme. This comprised 35km each week, of which just one hour was high-intensity intervals — just one fifth of the high-intensity group. Kenneth Powell, M.

Typically employed with running or cycling training, HIIT involves high-intensity exercise performed in short to long bouts interspersed with periods of recovery. Commonly associated with sport performance, HIIT has begun to be seen as an effective training tool for combating cardiometabolic diseases, improving vascular function and cardiovascular fitness, reducing insulin resistance, and improving metabolic health when compared with low- to moderate-intensity continuous endurance training:.
