HIIT is a form of interval training.
What is interval training?
Alternating periods of work with periods of rest.
What is Aerobic and Anaerobic mean?
Simply the terms "aerobic" ,running slower longer periods of time, and "anaerobic", Short intense bouts of exercises, refer to the presence and absence of oxygen, respectively.
Why intervals?
In the Gibala study, two groups were tested. It compared 20minutes of interval training 30sec on 4min off, compared to 90 -120 minutes of steady endurance heart rate zone, same improvements in oxygen utilization.(1)
This means that both groups had the same effect on there VO2 Max and one did more then half the work. So...
- Intervals develop aerobic capacity better then aerobic training.(1)
- The fastest way to raise VO2@ max, the standard measure of aerobic fitness, is through interval training.(1, 2)
Interval Methods
- Work to rest- uses a set time for work and a set time for rest
:15-:45 (3-1)
:30-1:30 or :30-1:00 ( 3-1 or 2-1)
1:00-2:00 or 1:00-1:00 ( 2-1 or 1-1)
As the interval gets longer the recovery time does not need to be as long as it relates to the interval.
Why do people still do aerobic training?
- Easier then interval work, and interval training is hard.
- Slow steady jogging or walking for long periods of time ( aerobic) is all they know.
Why should people do aerobic training?
- Aerobic training helps beginners.
- If you are going to or want to do aerobic sports; 5k's, 10k's, half and full marathons.
- The reality is that conventional aerobic training is only good to get a person fit enough to tolerate interval training (2)
If you want to lose weight, and be in great shape, interval training is the way to go. Interval training is great if you are pressed for time and can be done effectively and safely in about 30 minutes. It is also a great way to compete with your training partner.
