Question of Strength: April
by Charles Poliquin
Splits for Hypertrophy
Q: What's a couple of good splits to use if my main goal is building
muscle? Maybe something a little untraditional?
A: There's two ways you could do it:
Split #1:
Day 1: Chest and Back
Day 2: Anything from the bellybutton down (lower body)
Day 3: Off
Day 4: Shoulders and Arms
Day 5: Off
Day 6: Repeat the cycle
Split #2:
Day 1: Chest and Biceps
Day 2: Anything from the bellybutton down (lower body)
Day 3: Off
Day 4: Back and Triceps
Day 5: Off
Day 6: Repeat the cycle
Occlusion And Vibration Training: Valuable?
Q: Have you read anything about this occlusion training stuff ("
Kaatsu"),
where blood supply is cut off when lifting? Seems to be the rage in Japan.
What about vibration training?
A: Yes, and occlusion training is about as useful as tits on a bull.
How convenient is it anyway? You need an occlusion suit or bands that
restrict blood flow while you lift. You block and release blood flow,
going back and forth. They claim it gives you more hypertrophy, but
the studies were done on untrained subjects.
It's very gimmicky. If I make you do ten sets of five on the deadlift,
you're going to grow whether you're wearing an occlusion device or not.
No need to buy an anaconda to wrap around you when you deadlift.
Vibration training is the same. What are the odds that you're going
to do squats during an earthquake?
In all fairness, it has been shown to have some benefits with those
suffering from cerebral palsy and some other neurological disorders.
But there's a guy who studied under me who did his Master's thesis at
the University of Calgary on vibration training. He used it with Olympic
athletes and didn't see any effects, nor was he able to reproduce any
of the benefits reported in the previously published literature.
No surprise, last July a Dutch researcher came out and admitted that
they had falsified the data in a lot of the studies.
I'm not completely writing off vibration training just yet, but I don't
think it makes that much of a difference, and it's just not worth the
expense.
Honestly, my "colleagues" who are big into vibration training never
really made anybody strong anyway. About the only guy who endorses it
(who specializes in the combine business) also endorses occlusion training.
And he's only had one player stay with him after combine training to
train for the NFL.
Leg Extensions: The Rules
Q: Is there ever a good time to use the leg extension machine?
A: Most people know I'm not a huge fan of leg extensions. The
main reason is that I'm a big believer in exercises that give you the
most "bang for your buck."
Throughout my career, I've had, on average, only 11 weeks to work with
the athlete. For example, that's how much time off that NHL players have
to get in shape for the season. Time is money. And leg extensions are
usually a waste of it.
With that in mind, here are some random thoughts regarding leg extensions:
1. If you're going to use it, use the best machine. The choice of machine
is important. The best models are DAVID, Atlantis, Flex, and Avenger.
These are the brands that best match the strength curve.
2. The angle of the seat is important. Research shows that 90 degrees
is optimal. Angles such as 100 or 110 degrees decrease quadriceps recruitment.
3. The position of your toes affects quadriceps recruitment. This statement
is true when measured by magnetic resonance or by integrated EMG. The
basic rule is based on a continuum of recruitment. If the toes are in,
then there's preferential recruitment of the vastus lateralis. If the
toes are out, then there's preferential recruitment of the vastus medialis.
4. Follow protocols. Leg extensions should be done using hypertrophy
or strength-endurance protocols.
5. Wait until post-exhaustion. Leg extensions should be done in a post-exhaustion
fashion:
last in any quadriceps routine.
6. Research has shown that leg extensions are an oddity. Most exercises
show enhanced motor unit recruitment if done unilaterally (one limb at
a time.) Leg extensions don't. They show greatest activation when done
bilaterally
(both legs at the same time.)
So, leg extensions aren't a great exercise for athletes who are pressed
for time, but they can be a valuable addition to athletes who need greater
hypertrophy like bodybuilders or more local strength-endurance (i.e.
speed skaters).
The End for Flax Seed Oil?
Q: With supplements like Flameout and your own EPA/DHA blends, is there any reason to keep using flax seed
oil?
A: No, not flax seed
oil. But flax seed
hulls are good
for detoxification of xenoestrogens.
I've never been a fan of flax seed oil because if you're obese anyway,
you don't have the enzymes to elongate the molecule to turn it into the
omega-3s. So what's the point of using it?
Another problem is that flax seed oil is usually rancid in most stores,
with 40 out of 42 store-bought brands shown to be rancid in one study.
And even if you can get it fresh, it goes bad very rapidly once you open
it, sometimes in less than two weeks. Plus, I just found that flax oil
never really worked.
But flax
seeds can be used for the anti-estrogen effects and
for adding fiber to your diet. You can buy them whole or pre-milled,
but I'd rather grind them myself.
Make Me Vascular!
Q: Is there a way make yourself more vascular?
A: Yes. First, have low body fat. If you're 20% body fat you'll never
look vascular. Vascularity is inversely proportioned to how much body
fat you have.
But there are nutrients too that can increase vascularity. One of them
is a type of glucosamine that's blood vessel specific. Resveratrol,
because it can strengthen the vascular system, can increase vascularity.
Things that increase nitric oxides, like acetyl carnitine, taken long
term, will increase the elasticity of blood vessels and help you look
more vascular when you're pumped.
Vegetable glycerine, which is often used by bodybuilders before they
go on stage, can help, but it's temporary, lasting only about two hours.
Pull-Up Parameters
Q: What's a respectable number of pull-ups to shoot for? Or is it about
strapping on extra weight? And how can I increase my pull-up performance?
A: First, let's agree that a
pull-up is performed with the hands
pronated (palms facing away from you) and shoulder-width.
A chin-up, on the other hand, is done with a supinated grip (palms facing
you).
