Is cardio a necessity to lowering your pulse? Tom Cruze claimed he has a pulse of 32bpm on the GN show, sigh.

Anyway, so is it a combination of having good cardio and good meditative skill?

Now on top of that how do you increase your Apnea time? Clearly less pulse means less oxygen used.

I was watching a you tube video and he mentioned "Dive Reflex"


I still dont understand what that is but something to do with they found out in the 50s other mamals have it along with sea mamals etc.

Anyway, is static or dynamic breath holding better in the pool, or a combo of both?

The mammal dive reflex come into "action" as soon your cheeks are in contact with cold water. When you dive you will notice your heart rate slowing down significantly after the 30-40 sec mark.
There are whole books written about how to lower oxygen use and increase breath hold, but ultimately it comes down to what you want to use it for. Statics doesn't do anything to your bottom time, but will let you learn a lot about your body. Dynamics is the way to go, have a glass of orange juice beforehand (apparently acidic blood transports more oxygen) and keep on pushing. There are some yoga inspired breathing techniques that help a lot too, but you'll have to be persistent to feel an effect. Mullins will be able to tell you more (and likely correct me) The best way to increase bottom time is simply go out as often as possible.

Most important question is why are you diving? Followed by what do I need to do to achieve what I want?

For me I just want to get some crayfish and paua, have a bit of fun, and get some exercise. I don't need a 5 minute breath-hold to achieve this, I also don't need to get down to 20m to find cray, and as for exercise a couple of hours swimming around in the current and swell we can't get away from down here covers that easily. 75% of the crays we get down here are less than 5m deep, 100% of the paua we get are less than 3m. 

Occasionally when we go out with some friends who are on scuba we will drop on them at check their gauge to see how deep we are, best so far is 17m, but we don't practice this normally when out getting a feed as there is no need.

Cardio does assist in recovery times and stamina though, I have found that I can spend more time diving and get more dives in since I have started jogging with my daughter and taking a rifle for bush walks more often.

I think FF you are over thinking it.
 Heart rate is basically plumbing... If pipes/ arteries are clear, the pump in good knick.. it doesnt need to pump hard or as often.
Get your inner core and chest / shoulders fit..and drop a bit weight.. that will drop your over all heart rate...
Then there is recovery rate...test what over all condition the pipes a pump are in... Get the heart up to around 130 (that not high) take your pulse after a minute and if all good should drop about 25 beats... get it over 30 and you are starting to get into targets.
And while exercising, train to breath deep while doing so.
Then add breathing exercises couple times a day.
 Breath normal and after about 5 or 6 slow breaths get to to total MT  then total full.. and hold...every so often when can suck a bit more in to another cnr of the lungs....Dont strain too hard , but initial target 2 mins.. then build to 2 1/2 to 3 mins.. takes about a week with exercise.

This is more for us over 60s.. younger guys under 50 should be able to do it all off bat nps.

No not overthinking it, more I want to increase my time under water, not for fishing sake, more for the sake of experiecing more bottom time as I love just being under water so much but really dont enjoy the hassle of scuba. 

I agree static breath hold seems to do nothing for me.

I have a pretty good natural apnea, but no harm in wanting to improve it but I think its more in relation to how much oxygen Im using due to my heart rate/fitness.

That whole mamal instinct thing really fascinates me and from what I have read goes along way back in time.

Sprinters tend to have a reall low at rest heart rate, meditation I find slows my heart rate and I can do this very quickly. So maybe its a just improving my cardio interval training, which can be done in a pool, ie HIIT training. 

Jez paua and crays in the deep south dont count mate haha, you only need to hold your breath 10 secs to get your limit lol. Mmmm paua.

Start playing some under water hockey if there's a local team. if you're training in the pool try 50m dynamics with shortening surface intervals, but make sure you have a spotter as you can LMC or SWB.

Try pool training with leaving for a 50m underwater swim every 2 minutes - that's about a 50 second dive and a 70 second recovery. Do them back to back. Try to do a set of 30 in 60 minutes. No mean feat but once you've mastered that your recovery time will be reduced, your confidence to push yourself will be increased, and you'll be a more successful spearo. PS. Have someone watch you and both be training in blackout recovery.
Do or do not. There is no try.

Apnea is an interesting area where you are doing things foreign to most people.

You can do things to promote the onset of the dive response (mammalian dive reflex) such as wetting your face with cool water - in particular the areas below your eyes (above the cheeks).  Although some competitive freedivers with do dives with no warmup and "dry face" until they dive as this brings on the MDR a lot harder - IMO it is not much fun that way.

You can also train to increase your CO2 tolerance so that your body / mind is more used to doing things with higher levels of CO2 and not freaking out about it.

Static Apnea exercises can help - at least with your understanding of the feelings your body will go through.  They don't all have to be "how long can I hold my breath for this time?" exercises.   CO2 tables can help build CO2 tolerance e.g. a "pyramid" with static holds of a set time and ever decreasing surface interval in between each hold to a peak of 1 breath and then extending the surface time out again.  O2 tables can also help - where essentially you have a decent surface interval in between each static hold - and e.g. do a hold until your first contraction, come up and breath and clear all the CO2 out, another hold until the 3rd contraction, etc.

What Barx describes above is essentially a variant of a CO2 table for dynamic apnea.  You could also try a dynamic apnea pyramid.  For starters do this with 25m swims and then change to 50m swims at another session.  Swim the 25m (or 50m), have 1 minute breathing at the end, swim then 50 sec breathing, swim then 40 sec, swim then 30 sec, swim then 20 sec, swim the 10sec, swim then 1 breath, swim then 10 sec, swim then 20 sec, etc.

There are a lot of other exercises that will help you understand how your body feels.  Never do any of these alone - always have an active spotter (not just someone sitting on the side of the pool).
