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 planned trip
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 the ropes?”
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?”

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 work?”

64:00 Jaap Verbaas with the three latest articles from FreediveWire.com
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 chemoreceptors.
- Physical CO2 tolerance may be governed by blood volume and quality, which is commonly overlooked in CO2 tolerance training.
- 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 chemoreceptors.
What do lactate and lactic acid have to do with freediving?
- 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 produces lactate.
- 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 rate.
- 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 produced
- Endurance training drastically reduces recovery time
- Base cardio is very beneficial to recreational freedivers and spearfishers
- Base cardio is likely very beneficial to competitive freedivers
- 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 dynamic-no-fins.

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.
