Dr. Mercola Interviews Doug McGuff about High Intensity Exercise

[US51351142]

So enlightening. I've been killing myself 5 days a week. Just finished first 3 day recovery period. Never felt better. Stepping it up to 4 days after Monday's workout not to return to Planet Fitness until the following Saturday. Love it, just love it. Thank you Sahib.

Great insight...will def incorporate them into my workout protocol!

HIT training has it's applications to those of us that are competitive cyclist. So lets not disparage the idea of cardio. I changed my training several years ago from 60 to 100 miles a day of training, back to 30 miles a day with one 100 mile ride each week and found that pushing at my maximum for 30 miles produced more power with none of the recovery problems I'd suffered with for years with more volume. Running a HR at 175 to 190bpm for me has been the point were I produce the best race result

I would agree with this training principle. Last summer I did high intensity multi-hour bicycle rides a few times per week along with running, Pilates, weightlifting, rowing, and swimming. The result . . . adrenal failure with a testosterone and cortisol crash. After a 4 month break my body basically favored a short duration moderate intensity interval exercise regime.

This interview really blew me away. What an inspiration. Thank you so much Dr. Mercola and Dr. McGuff!

I want to thank Dr. Mercola for these top notch interviews. It really made my day!

Great and enlightening interview, although I've seen him exercise and it appears he is hyperventilating when things get difficult. He mentioned heart stroke volume rising, but not pulse rate so much, perhaps the hyperventilating is supposed to get more oxygen to the muscles when the heart doesn't raise its rate. I don't think the hyperventilating aspect is too good, I would mix super slow with other speeds to get the benefits but not hyperventilation. I should really look into it further.

@adrianwaj That "hyperventilating" you observed is deliberate, to avoid the occurrence of val salva. At the end of a high intensity set the natural tendency is to want to hold your breath, so the trainee employs a faster breathing pace as a mental and willful choice (it is not physiologically driven) to avoid an increase in blood pressure that holding the breath would cause.
