The same results exercising in just 1/5 the time

A study examined the effects of two different exercise protocols on health indicators such as insulin sensitivity and cardio-respiratory fitness. The two protocols: the sprint exercise protocol (SIT), three 20-second ‘all-out’ cycle sprints with two minutes of easy cycling between sprints and the moderate-intensity continuous training (MICT) protocol, 45 minutes of cycling at a moderate pace. Both had warm-up and cool down periods.

A quote from this article, No time to get fit? Think again, that reported on the study:

“After 12 weeks of training, the results were remarkably similar, even though the MICT protocol involved five times as much exercise and a five-fold greater time commitment.”

From this article, Even Short Bursts Of Exercise Can Reverse Heart Problems In People With Type 2 Diabetes, come these quotes:

“In a new study published in Diabetologia, researchers examined the effect of brief, high-intensity workouts on type 2 diabetes patients who had already experienced heart abnormalities due to the disease. They found that these short bursts of exercise had a positive impact on the patients, improving their heart structure and offering some of the best protection for diabetes control.”

"The researchers measured cardiac structure and function with MRIs, and they found that these high-intensity, intermittent workouts greatly improved heart structure and function."

High intensity sprint training you can stick to

With any exercise program if you set the bar too high you’ll likely quit. Set the bar lower and you are more likely stick to it and see more results in the long run.

One way to do sprint training that I have seen recommended and I have tried:  Warm up on an exercise bike or other aerobic equipment.  Then go as fast as you can for 30 seconds.  Recover at much slower RPMs for 90 seconds then repeat the cycle for a total of eight sprints. If you are truly going as fast as you can it will take a long time to acheive eight all-out sprints.  It is grueling. It took me months to build up to eight sprints. I had great results, but I absolutely hated it. I had a sense of dread whenever I would go into the gym to do it. I eventually quit. 

Trying to go as fast as you can is a euphemism for trying to withstand as much pain as you can. These sprints are difficult. Approaching spring training in this manner was, for me, a prescription for quitting.

Sprint training for fat loss

personal trainers at work personal training New Orleans

From this study, High-Intensity Intermittent Exercise and Fat Loss comes this:

Dosage:

A thirty second all-out sprint of on a bike, recover at a reduced RPM, repeat four to six times. Do this three times a week for two to six weeks.

Results:

1. Increase both aerobic and anaerobic fitness.
2. Significantly lowers insulin resistance
3. Skeletal muscle adaptations that result in enhanced skeletal muscle fat oxidation

Long distance running lowers testosterone; sprint training increases it

personal trainers at work personal training New Orleans

From This study, Effect of altered reproductive function and lowered testosterone levels on bone density in male endurance athletes: "Relatively short duration exercise bouts at maximum or near maximum intensity appear to increase serum testosterone levels, with measurable changes evident within minutes. However, with prolonged acute submaximal exercise bouts of approximately two hours or longer, suppression of circulating testosterone is noted which may remain for several days. "
