Shrek - Turbo and the NS Community
Turbos back!! ....and we get up to mischief in episode 100 - the
Community Special! This episode features listener calls and
questions as well as some expert advice about CO2 tolerance and
training from Jaap Verbaas. This episode was fun and as usual
educational. Check it out and leave a comment:)

10:40 What’s Turbo been working on?
11:30 Patreon: What is
the plan for the funds from the Noob Spearo Patreon. Our PATREON VISION:
Turbo and I would like to dedicate 100% of the funds to trips.
Interviews on the road, going spearing with listeners, organizing a
talk or live interview and enjoing travelling to meet our
listeners. We have $130 USD in there now and its growing.
August 2019 Melbourne Trip is our first tentative
14:00 Random community questions
- “I've recently made the move from north Queensland to southern
Queensland and I've noticed a lot of the diving is deepwr. How do I
make my way from a 10-12m diver to hitting 18-20m?”
2. "How can I get out spearfishing more?”
3. “How do I find someone experienced to take me out and show me
4. Alex "I've had my speargun for about a year now, I was just
wondering if you guys had any actionable information that could
help me out?"
5. Hand Spear or Pole Spear Tips
28:30 Rhys Clay Listener Call
38:30 Richard Metzger "In listening to your shows a question
that always lingers with me is what do the spearos do for their
professional carers to make money to support their spearing?
I know a lot of the guests are not full time professional
spearos so i am always interested to learn how they are able to
maintain a regular job and still travel and get out in the water.
Especially for those who travel the world for long periods of
time - do they work in each spot they visit? Do they save up and
live on the cheap as they travel? How do they make the money

CO2 tolerance is complicated, hence this post is complicated.
Hopefully it is less complicated to read than it was to write. Just
in case it gives you a headache, here are the highlights:
- CO2 is transported in three ways: bound to hemoglobin, as
bicarbonate ion, and dissolved in the blood stream.
- Red blood cells are crucial for generating bicarbonate ion, and
for facilitating CO2 bound to hemoglobin.
- Only dissolved CO2 can diffuse to the central
- Physical CO2 tolerance may be governed by blood volume and
quality, which is commonly overlooked in CO2 tolerance
- Endurance athletes commonly have the highest CO2 tolerance and
storage (in comparison to short and mid distance sprinters).
- Mental CO2 tolerance focuses on desensitization of the central
What do lactate and lactic acid have to do with
- We do not produce lactic acid.
- We produce lactate. We do also, however, produce H+ in muscle
cells. Combine the two, and you have lactic acid. However, the
reaction producing the excess H+ is separate from that which
- Lactate is produced continuously, even at rest.
- Even when excess O2 is available, we produce lactate.
- Lactate is not metabolic waste
- Lactate is used as fuel, both directly and indirectly.
- Once O2 becomes limited, lactate starts accumulating and
enters the bloodstream (we'll call it blood lactate)
- Lactate is actually slightly basic... not acidic. But, H+
starts accumulating in the bloodstream too, although at a different
- Blood lactate can be converted to glucose in the liver, or
taken up by the muscle cells once the workload decreases.
- Blood lactate increases rapidly when you hold your breath, even
while doing a static.
- The dive reflex promotes anaerobic metabolism. The increase in
lactate shows that the oxygen supply to the non-essentials is
effectively cut off.
- Peak blood lactate is highest in mid-distance sprinters,
indicating sprinting might be a good method to train for
freediving. However, endurance training reduces the amount of
lactate that accumulates in the blood without affecting the amount
of lactate produced in muscle cells. Perhaps we need a bit of both
types of training, and perhaps this is why most freedivers believe
that high intensity interval training works wonders (it is somewhat
in between mid distance and endurance training).
Where does lactic acid come in? Well, hydrogen and lactate occur
in equilibrium with lactic acid (H + lactate = lactic acid). In
blood plasma the rate is about 1:20 for lactic acid to lactate. So
lactic acid does play a role, but it is minor. Actually, it is
minor when it comes to muscle functioning.
What cardio can do for your freediving
- Many freedivers shy away from cardio because they believe that
cardio does not benefit freediving. However:
- Endurance runners have the highest blood volume compared to
short and mid-distance sprinters
- Endurance runners have the highest blood quality (Hb) compared
to short and mid-distance sprinters
- Endurance runners have the highest CO2 storage capabilities
compared to short and mid-distance sprinters
- Endurance training reduces the amount of lactate that
accumulates in the blood without affecting the amount of lactate
- Endurance training drastically reduces recovery time
- Base cardio is very beneficial to recreational freedivers and
- Base cardio is likely very beneficial to competitive
- VO2 max has never been shown to negatively effect freedivers of
any kind, however there is some theoretical basis to say that it
will negatively effect pool disciplines such as dynamic and

28-day Freediving Transformation. Want to
increase your bottom time? Want to lower your comfortable operating
depth? Want to increase your breath hold? In 4 weeks you can
transform your physiology to improve your performance as a
freediver. Learn the proven strategies competitive freedivers
use to strengthen their performance.
Make you equalization problems a thing of the
past. If you are freediver who struggles to equalize
your ears in the 15-30 ft range this course is the answer. I’ve
taught over 500 people to equalize for freediving via my one
on one Skype sessions. I’ve taken that method and turning in into
an online course with over 14 videos discussing every equalization
problem I’ve ever encountered.
Tuesday Ted Talks Freediving. 19 one hour
live Instagram episodes where I discuss a variety of freediving
topics and answer peoples question live on Instagram.
