HIIT and sprint intervals are two kinds of exercise programs that can give you all the more value for your fitness fee.

Hoping to lose weight through exercise? Intense workouts are more effective with your time, they also burn off the calories faster too.

Interval training, for example running sprints is more effective for weight loss than constant, moderate exercise like brisk walking or biking under 15 kilometers per hour over long distances, published in a new study for the British Journal of Sports Medicine.

"Tabata sprints — running hard for 20 seconds followed by 10 seconds of rest — and burpees, or squat thrusts, with pushups are examples of interval exercises that can be done at home."
“The best part about this kind of exercise is how brief the sessions can be. We have people that get results coming once a week for 10 minutes, with the average being 45 minutes a week,”

said Josh Jarrett, chief exercise officer of Quantify Fitness of Nashville.

The new study was a summary of recently published studies. It goes somewhat against most physical activity guidelines, which in general accentuate the length of the exercise — an hour or more each day for weight loss, for instance.

“Few people meet these guidelines,”

noticed the study, which was led by Ricardo Borges Viana, a faculty member in the physical education and dance division at the Federal University of Goiás in Brazil.

Specialists reasoned that a short blasts of action together with short recuperation periods can decrease both body fat and overall weight.

“During the intervals, the muscles burn a significant amount of their sugar stores, which triggers a reaction causing them to rapidly re-fuel by sucking glucose from elsewhere in the body. This process requires insulin, and over time the body responds by becoming more sensitive to small amounts of insulin. If insulin levels are high, the body is unable to burn fat as efficiently, so by making the body more sensitive to smaller amounts of insulin you are able to re-engage the fat-burning machinery,”

said Jarrett.

"Intense exercise depletes the oxygen available to the muscles, forcing them to burn fat for energy instead,"

added Jarrett and noted:

"The body burns calories for hours after the workout ends in order to make up for the resulting oxygen debt."

HIIT the trail and sprint

The study didn't advice any specific exercises.

Nevertheless, the two most accepted methods are high-force interval training (HIIT) and dash interval training like running, jogging, speed walking, and cycling.

Disregarding gender or starting weight, both moderate exercise and interval training diminished weight and body fat over a four-week time span.

Still, interval training produced 28 percent more weight loss, with sprint interval training appeared to be the best and most effective process to lower body weight rapidly.

Varying four minutes of jogging with 30 seconds of all-out sprints is a case of sprint interval training.

Different workouts can include hill climbing and shifting the length of sprinting and running intervals as well as the quantity of sets performed.

Of the major sports, ice-hockey comes closest to giving a run interval training workout with its short, high-energy turns on the ice alternating with brief periods of rest on the bench.

Specialists state you don't need to thoroughly update your present workout in the event that you need to consume fat all the more rapidly.

“Interval training can be performed doing the same exercises you are already doing, whether it’s running outside, doing cardio in the gym, lifting weights — anything that is already steadily elevating your heart rate,”

Said Adam Padgett, a certified personal trainer from Rancho Cucamonga, California.

“However, to perform interval training you need to be focusing on alternating your pace and intensity. If you are running outside, instead of just running at a steady pace most of the way, run as fast as you can for 20 to 30 seconds, followed by maintaining a jogging or walking pace, or just stopping completely depending on your skill level. If you’re lifting weights, line up two to four exercises to perform back-to-back without resting, before again resting or slowing the pace. A recommendation would be perform four to five intervals before stopping,”

he continued.

Emma Green, PhD, a certified personal trainer in London and online fitness coach, warned against exaggerating the study conclusions.

“Although the difference in weight loss was statistically significant, the actual amount was tiny.  Interval training resulted in 1.58kg fat lost (less than 4 pounds) and steady state cardio resulted in 1.13kg lost (less than 3 pounds).”
“It’s important to note that because interval training is so tough on the body, it is not suitable for those who are beginners or those who are injured,”

said Green.

The study authors additionally advised counseling a doctor before starting interval training, noticing that there is a possibility of injury and greater cardiovascular stress.

In A Nutshell

Both moderate, continuous exercise and high-intensity interval exercise can decrease body fat and weight.

Nonetheless, interval training is more effective and efficient for weight loss.

Interval exercises can combine running sprints alternating with light jogging or periods of rest.

To prevent injuries, consult with your physician before doing an intensive interval workout.
