I've talked about intervals before. I spotted this new article; there wasn't much in the abstract, so have bought the whole thing and will comment more when I've had a chance to read it.
Exercise & Sport Sciences Reviews. 36(2):58-63, April 2008.
Abstract:
High-intensity interval training (HIT) is a potent time-efficient strategy to induce numerous metabolic adaptations usually associated with traditional endurance training. As little as six sessions of HIT over 2 wk or a total of only approximately 15 min of very intense exercise (~600 kJ), can increase skeletal muscle oxidative capacity and endurance performance and alter metabolic control during aerobic-based exercise.
Thanks for the link. That's an interesting study.
ReplyDeleteI have warmed up to intervals in the last few months due to your blog, Mark's, and Art's.
ReplyDeleteIt does seem to produce superior results in little time. I suspect its benefits stick with you longer i.e., it takes longer to become de-trained.
Two other quick observations. (1) It is easy to over-do intervals. A little will go a long way. (2)Each Interval duration probably should be 20 seconds or less. I feel refreshed afterwards and next day if my kb snatches / sprints are less than 20 second bursts. Anything over 30 seconds starts pushing me closer to the red zone.
