Medscape.com reported on research study released February in the British Journal of Sports Medicine that concluded, “interval training may result in greater weight loss than continuous exercise, with sprint interval training (SIT) the most effective.” In addition, “interval training also may be easier for obese and older individuals to perform.”
This conclusion, by scientists at the Federal University in Goias, Brazil, was the outcome of an organized evaluation and meta-analysis, which compared weight loss accomplished with interval training – high and moderate strength – versus moderate-intensity, constant training (MOD).
According to Medscape, “after pooling results from over 1000 individuals, they found both interval training and MOD led to significant reductions in both total body fat percentage and total absolute fat mass.” But, “interval training was associated with a reduction in total absolute fat mass that was more than 28% greater than that seen with MOD, with the greatest reductions seen with SIT.”
In December 2018, released research study in Frontiers in Physiology compared the results of 8 weeks of 2 kinds of interval training – (SIT) and High-Intensity Interval Training (HIIT), on anthropometric procedures – height, weight, BMI, and percent body fat – and cardiorespiratory physical fitness in healthy girls.
The HIIT group carried out 4 periods of 4 minute period at 90-95% of peak heart rate (220-age) on a fixed cycle – with 3 minutes of active healing (light biking) at 50-60% of peak heart rate, while the SIT group carried out 4 periods of “all out,” thirty 2nd biking – with 4 minutes of passive (total rest) or light biking without any load.
It was identified that, “eight weeks of HIIT and SIT resulted in improvements in anthropometric measures and cardiorespiratory fitness, even in the absence of changes in dietary intake.”
In addition, the SIT procedure triggered bigger skinfold decreases compared to the HIIT. Both procedures seem time-efficient interventions, “since the HIIT and SIT protocols took 33 and 23 min (16 and 2 min of effective training) per session, respectively.”
The Brazilian scientists explain that SIT might increase the injury threat and increased cardiorespiratory tension in specific populations, who might not have the ability to adapt to the greater strength level. However, they likewise explain that, “for obese people, virtually everything involves high intensity, because of their low fitness level and because they have to carry a heavier load.”
The Brazilians likewise state, “older people also might have difficulty sustaining exercise for longer periods, which might make interval training a good alternative.”
From my experience monitoring detailed weight management programs and research study for my book, The Fat Burning Bible, it was apparent regarding the advantages of either HIIT or SIT, when integrated with circuit resistance training – moving from one workout to the next, rotating in between the upper and lower upper body. Those advantages consisted of: a boost in resting metabolic rate; a decrease in overall body fat; and, a boost in cardiorespiratory physical fitness over a three-month duration.
Using heart rate tracking throughout the training, after determining the weight loss individual’s optimum endurance capability – VO2 Max – and figuring out the anaerobic limit, we determined the maximum target heart rate training zones to speed up weight loss in the fastest training duration – with HIIT or SIT.
Life is an endurance occasion with periodic sprints – approaching a goal pressed method down the line. The goal is compressed morbidity, the fastest duration of disease pressed to the end of life.
After years of screening numerous people – both professional athlete and non – of any ages and sizes, I reached the point of having the ability to hypothesize – based upon the lead to grownups of the VO2 max and the anaerobic limit test– who may make it through the very first hour after a cardiac arrest.
It all boiled down to HITT or SIT. What’s in your future?
