High impact can mean high rewards

Can fat really be gone in 60 seconds? Not quite, but not too far off.

Researchers have found that a few minutes of high intensive interval training (HIIT) a few times per week delivers the same long-term results as spending 20-30 minutes on the elliptical or treadmill.20110921_S

In the short term, the study revealed that the HIIT showed immediate increases in certain proteins associated with improvements in endurance capacity. But when researchers studied the effects in a longer timeframe, the difference between going all-out in short spurts in a short time wasn’t dissimilar to those of a longer, less strenuous workout.

“It would appear that there is something important, even essential, about the pulsative nature” of on-off HIIT training, Martin Gibala, chairman of the department of kinesiology at McMaster University, told the New York Times.

So maybe you don’t have to spend 2-3 hours at the gym each week in order to stay fit. A few sessions per week of 45-second high impact intervals with a minute break in between may be all you need. Of course, that’s if your body — and mind — can handle it.
