MIni book review: specialized but worth reading
52 minutes ago
b2d: a blog about (1) trying to understand how we work, in terms of health, fitness and well-being (2) sharing that understanding (3) trying to figure out or review best practice to optimize and operationalize (ie make it work) that practice for us.
There's been some discussion on the DD forum of late of what constitutes Cardio workouts, and what are optimal KB routines for cardio. It may be that we need to get our terms agreed. There's a difference between high intensity interval work (like Kenneth Jay's VO2max Protocols, such as the
original, belowhigh intensity work stimulates the sympathetic nervous system (fight or flight) while low intensity work stimulates the parasympathetic nervous system (rest and digest).
Also, as said above, another benefit of cardio work is to enhance mitochondria. These are the little elements of cells that DO that aerobic energy work with the O2. Going beyond 80% MaxHR - going outside the aerobic zone - has not been seen as optimal for mitochondria focus. My understanding is that there's an hypoxic effect on mitochondria when going anaerobic, and that impacts mitochonrdria hyperplasia (the reproduction of these cells).While the present study demonstrates the potency of SIT to elicit changes in muscle oxidative capacity and selected metabolic adjustments during exercise that resemble ET, the underlying mechanisms are unclear. From a cell signalling perspective, exercise is typically classified as either 'strength' or 'endurance', with short-duration, high-intensity work usually associated with increased skeletal muscle mass, and prolonged, low- to moderate-intensity work associated with increased mitochondrial mass and oxidative enzyme activity (Baar, 2006). Given the oxidative phenotype that is rapidly up-regulated by SIT, it is possible that metabolic adaptations to this type of exercise could be mediated in part through signalling pathways normally associated with traditional ET.In other words the 02 deficit may be SO HIGH after this effort your body may up-regulate O2 consumption afterwards, which impacts the aerobic system. So it might be the rest intervals during and post the effort where the aerobic ET-like adaptation is occurring. Dunno. Speculation.
It should be noted that although interval training groups spend some of their training time at a very high intensity, a similar amount of time is spent at a lower intensity, and therefore the mean intensity of training may not be any higher than that of a continuous training program. In the current study, the interval training group used 5 min each for the work and the recovery phases of the intervals and had an average intensity of 72% HRR, which is slightly less than the 75% HRR of the vigorous [the steady state -mc] group. The work-recovery periods of Helgerud et al.[16] were 4 min at ∼93% HRmax and 3 min at 70% HRmax, for a mean intensity of 83% HRmax in the interval group, whereas one of the continuous groups used 85% HRmax. Warburton et al.[37] used 2 min at 90% HRR and 2 min at 40% HRR for the work and the recovery phases, yielding a mean intensity of 65% HRR in the interval group, and had the continuous training group use 65% HRR. Wisloff et al.[38] used 4-min work phases at ∼93% HRmax and 3-min recovery phases at 60% HRmax, for a mean intensity of 79% HRmax in the interval group, and used ∼73% HRmax in the continuous training group. Despite the similarity of mean intensity between the interval and the continuous training groups, the interval groups in all of these studies experienced greater improvements in aerobic fitness after training. Therefore, although intensity is a key variable in cardiorespiratory training (as shown by comparing the two continuous training groups in this study), the mean intensity may not be as important as the highest intensity that is used for a significant portion of the training. A topic for future research is to determine what portion of training should be done at high intensities and using what work-recovery periods to obtain the greatest results [emphasis -mc].And another interesting find in support of high intensity intervals - though again not necessarily VO2max (no info in the study on that point), is a recent study on rowing (an activity that KJ argues is similar to KB'ing). It shows that doing endurance work is actually pretty important if doing resistance work for the heart - to keep it elastic (endurance benefit) rather than thickening it (effect of heavy resistance work). Their rowers, they said, did 65% of their work at "high-intensity" - though that's not further defined. The conclusion is, "Our results suggest that simultaneously performed endurance training may negate the stiffening effects of strength training."

Here's why i think Precision Nutriton is the best process & place to learn about nutrition for health & body comp goals. And here's a free 40page+ ebook overview of the approach.

For folks interested in intermittent fasting, folks i trust keep recommedning Eat Stop Eat.
If you're wondering what zhealth is,
Gymboss
Lighter, smaller and less risky stuck on a rack at the gym or taped to a wall than your phone as an interval timer for things like,
oh, Viking Warrior Conditioning (overview here)
Lots of folks are interested in ketogenic dieting. The best reference out there is still Lyle McDonald's The Ketogenic Diet Book - helps you make an informed choice if you want to experiment with this approach.
if you work with athletes this is a nice way to be able to point out issues for the athlete to see, as well as to show how much they've improved with your tutelage via side by side comparisons of before and afters.
I also regularly break up the rice with cool stuff like Hemp Protein also from
True Nutrition
either the Extreme (of course extreme) Warrior Force protein or even wilder and somehow crazier just this side of visionary, are the "elite green" proteins. They have sample sizes, too. In GLASS jars. Seriously, i like this stuff a lot. But it's not quite something i can afford as an every day protein. But mm mm mm. weirdly wackily awesome.

Since this info used to be available at Dragon Door (link no longer working within new forum) and at Rif's blog (no longer publicly accessible), allow me to repost Kenneth Jay's original DD post on his first VO2max protocol, from the post "true cardiovascular kettlebell training: improving the SSST (long)
----------------------
I will share with you one of my best advanced protocols for improving VO2max and lactate buffering capacity using the kettlebell.
To improve the 10 min. SSST you need to tax the oxidative energy pathways as well as the glycolytic pathways. Basically that means that you should train to stimulate your VO2max and your lactate producing and buffering capacities.
The program below is derived from the latest research on improving 10-15 min. work bouts. Most research is done on running and bicycling for good reason but based on findings from these studies it is possible to specifically design optimal SSST programs using this data and the knowledge of VO2 kinetics during submaximal and maximal work.
I will not go into the deep theory behind this kind of training but rather just provide you with a protocol you can start doing immediately. Should you be interested in knowing in detail why and how it works I hope to see you at the RKC II where there is a possibility of discussing it further.
The first thing you have to do is to establish at what snatch cadence you come the closest to eliciting your VO2max. This is done by doing an incremental test that lasts no less than 6 minutes. Basically you just start out very slow and for each minute you increase the cadence. When you have get to the 6th minute you go all out snatching as many times as you can without stopping for at least one minute. The test might look like this but is subject to individual differences:
1st minute: 10 reps left arm
2nd minute: 12 reps right arm
3rd minute 15 reps left arm
4th minute: 17 reps right arm
5th minute: 18 reps left arm
6th minute: 26 reps right arm (all out effort)
The 6th minute reflects your VO2max cadence, hence that will be your interval training tempo. It is very important for the protocol that you continued snatching for the entire 6th minute. (make sure afterwards you balance out the numbers of snatches performed on each side so each side get a total equal amount of work).
In this example the VO2max cadence = 26reps
The interval work/rest time is determined to 36 sec. which is 60% of one min.
In those 36 sec. you need to keep your VO2max cadence = 26reps x 60% = approx. 16 reps.
So the setup is as follows:
VO2max/lactate tolerance and buffering:
Work/rest ratio: 1:1 (36 sec of work separated by 36 sec of rest.)
Number of intervals: at least 10 and the goal is to work up to 17+ sets before you test the SSST.
Number of reps per set: 16 (it is very important NOT to go faster or slower. DO NOT speed up to get more rest- it will ruin what you are trying to do.)
If your hands can take it do this at least twice per week. Only substitute with swings if it is really necessary. The program is based on the specific VO2 kinetics of the snatch not the swing.
The program is very taxing and one should always build up volume slowly.
Now go be an animal and try it!

mc,
just checking in. We have been crossing paths on the various forums. I'm still going strong on the plant-based eating that you inspired in me. I just want to commend you on being such a wonderful resource for us. As a matter of fact, if you bottled your bathwater, I would make it my chief supplement. I'm certain even your offscourings would be beneficial.
Ron, nice to see you. Hope your term's been going well, and way to go staying green. coolio. you take care into the Dark and Cold winter.

What a fantastic article. I'll be getting some kettleballs then!

I'm so impressed with how thorough and even handed this article is. A rare gem in the blogging community. I'm glad I found it.
Thanks for visiting b2d Tamson.
