The benefits of interval training were discussed on Tuesday nights Catalyst. They discussed the benefit of sprints. They were discussing exercising hard, for 30 second intervals with a four to five minute rest. Four times. They noted that you may need a good 20 min warm up.
They suggested that the effects of interval training go all the way to the cellular mitochondria. These are the power house of the cells.
This training may reduce the effect of free radicals, and lead to improvements in fitness, and slow down the rate of ageing even in the skin......
The guinea pig, whoops, presenter stayed with this training regime for 15 weeks and showed an improvement in body composition, namely a reduction in body fat, an improvement in VO2 max, the measurement of aerobic fitness and in crease in number and activity of mitochondria.
We have met this idea before, Michael Mosely did a documentary on abbreviated training.
I believe these fast sprints confer benefit and should be a part of a good exercise program even for older adults... That is why we have been doing these 8 sec sprints 12 seconds slow, intervals for MORE THAN TEN YEARS now.
Glad everyone else is catching on.
The show, Catalyst, is well worth a look .. I'm sure you can watch this episode on line. In fact, here is the link http://www.abc.net.au/catalyst/stories - six minutes of exercise
