#4 - Is high intensity interval training (HIIT) the best way to train? With Dr Marty Gibala

Dr Glenn McConell chats with Professor Marty Gibala from McMaster University in Canada about the physiological effects of high intensity interval training (HIIT) compared with continuous submaximal exercise training. Comparisons between the effects of HIIT and sprint interval training (SIT) are also discussed. The immense interest in HIIT was initiated by a ground breaking study that Marty conducted in 2005 comparing HIIT to submaximal exercise training. He has since been at the forefront of the area. The discussion focussed on HIIT vs SIT vs continuous submaximal exercise in regards to aerobic capacity, exercise performance, cardiovascular function, weight loss, insulin sensitivity and adherence to training. Sex differences in response to exercise training were also discussed. It was apparent from the discussion that although a lot is known in the area there is still much to learn.

Very glad to hear you guys are concerned for science communication. There are a lot of us out here concerned for good health rather than optimal athletic performance.

Great questions. It would be interesting to see more research on slow-twitch mitochondria content from SIT, but it appears that may be the 1 thing that it can't replace from continuous moderately easy exercise.

I'm wondering if the continual glucose monitors (linked to computer analysis) could be a way to get personalised profiles of the effect of exercise. I think of this as the equivalent of Tim Spector looking at the gut microbiome.
