New cool research in the Journal of Strength and Conditioning; we review it:
“Effects of intermittent hypoxic training (IHT) followed by intermittent hypoxic exposure (IHE) on aerobic capacity of long-distance runners.”
Highlights of the study:
-Does IHT improve aerobic capacity?
-Aerobic capacity post IHT (Does detraining occur after ending IHT?
-Does IHE (exposure at rest) attenuate detraining effect after IHT
Three groups of trained endurance runners including a control; single-blind:
1) group 1: 6 weeks of IHT, 4 weeks of IHE
2) group 2: 6 weeks of IHT, 4 weeks of normoxic exposure
3) control: 6wks of regular training; 4 wks of normoxic exposure
-Two training sessions per week for groups 1 & 2 were IHT. Subjects lived and trained at 760m.
-Lactate threshold and running economy improved in all groups at post-training, but VO2max, vVT1, and vVT2 improved only after IHT, while improvement in VO2max was inversely associated with baseline VO2max;
-There was no detraining 4 weeks after IHT, with or without IHE. IHE was not required to maintain training adaptations.
-IHT induced more physiological adaptations than NT, which indicates that IHT may be a useful strategy to improve sea-level aerobic capacity of athletes with an intermediate level of aerobic capacity.
-Hemoglobin concentration did not change after IHT or NT. On the other hand, VO2max improved after IHT. Altogether these results suggest that hematological factors do not seem to explain VO2max improvement. An alternative explanation could be the IHT effect on hypoxia inducible factor-1α (HIF-1α), a non-hematological factor. It has been shown that HIF-1α contributes for changes in mitochondrial function and expression of genes related to redox regulation and glucose uptake after IHT
How much do these little things like IHT matter? Is it too much of a “quick fix” and should we be about the bigger picture on what goes into a good performance, i.e. the psychology, mental toughness and other variables, like health, that matter. And a tangent on IMAZ and Andrew Starykowicz’ bike split and overall race execution.
Answers to questions:
– For an age-grouper, is there any real advantage considering a new bike? Or stick with what you got if it seems to be working?
– 650c vs 700c wheels
– Lots of bike knowledge from Lucho!!!
– How to tackled single leg squats (pistol squats) effectively and safely into a strength training routine?
– How far should you go down; what is safe and how to progress to go deeper
– What’s the different between form on a pistol squat vs a weighted front or back squat – it matters!

HIIT vs. MAF
– Pros and cons of HIIT? Can HIIT complement a committed MAF approach? Or not? How to decide if you should be doing HIIT or MAF…
– should a MAF-based athlete add in some speedwork a few weeks before your marathon?
