Immersion diuresis, which literally means “water loss due to immersion,” is the culprit behind that urge to pee when you are in the water. The lower temperature and increased pressure of the surrounding water makes you pee. It’s really as simple as that. Immersion diuresis is a physiological response to being submerged in water and it’s actually part of the Mammalian Dive Reflex. When the body is immersed in water the colder temperatures and increased pressure from the surrounding environment causes a narrowing of the blood vessels (vasoconstriction) in your extremities. As a result of this vasoconstriction, your body moves blood volume away from your skin and extremities and redistributes it towards your core areas. So your coach was partially right with the cold part; the other parts being the increase in pressure and the mammalian dive reflex. Nice work out there Lionel! Can’t wait for the next video

@@taylorcall2951 he is not being compressed under water. He is swimming on the surface. What makes him urinate is the following: the cold water causes his peripheral blood vessels to constrict, redistributing blood flow to the core to maintain normal core temperature for the vital organs. This causes an increase in blood flow to the kidneys, causing an increase in urination. The opposite happens in heat. Dr Edson

I hypothesize that the conventional thinking and practice of contraction of the abdominal muscles during swimming, for example; drawing in the belly button and maintaining tension in the abdominal region to assist your streamlining, might be over stimulating Lionel's abdominals and may be a contributing factor in creating excess pressure on the bladder. Practising intra-abdominal pressure while swimming (in conjunction with overall practice of Dynamic Neuromuscular Stabilisation, or DNS) could reduce this factor by creating more room in the abdominal cavity for the organs, more room for the diaphragm to expand into for more efficient breathing while still giving support to core region. Also, it allows better rotation through the thoracic area by reducing excessive tension of the abdominal muscles which may increase overall swimming ability.

I would have the same skeptical look as Lionel when the coach is explaining his HR going down on the second lap with his form falling apart and stating that he is getting the same power output.? Seems to be some flaw in that logic. Every other discipline, form collapse equals less efficiency with an increase in HR to maintain the same power\pace. But maybe I only caught part of the conversation and didn't understand what he was actually saying.
@bow.10734 жыл бұрын
I am still pondering the decreased HR. I am wondering if they tracked his stroke rate on the return. He said he had the same perceived rate of exertion and was 1:30 minutes slower with a HR decrease by 10 beats and felt fatigue limiting him. Wouldn't surprise me if he still had quality strokes but glide phase increased resulting in decreased stroke rate but also decreasing his HR.

A bit of scissors kick, especially the first after breathing. Which, I guess, comes from kicking too much from the knee, rather than the hip. And having the legs spread that wide creates hack of a lot of drag. Lionel's swimming has improved substancially, but there are always small things that can make big difference if corrected. And this is an easy one to correct. And well, buying a 2nd hand wetsuit is never a good idea😁 Anyway, nice approach, having it all dialed in based on pro research. No place 'bro science' here 😉

It's common to cut weight (sweat) by taking Epsom salt baths. I don't think it's the same as sea salt but you do sweat when swimming - usually less than when running but the amount varies from person to person so you could be sweating a lot more than when running compared to others. Do you use any lotion before a race on your body? Another weight cutting technique is to use alcohol with a bath because the body reacts by sweating more - commonly used by fighters, weightlifters, etc.

Swimming is the best to teach Newton Law, its pretty simple if you care to learn about it. Why your HR goes lower when you feel like you're putting more effort and actually going slower. Yeah the cause of peeing in the water, is called vasoconstriction. The body constrict the blood vessel to direct the heat towards the core to keep it warm, so this puts strain on your arterial valve(increase in blood pressure). And the best way to manage blood pressure is to relief bodily fluids, in this case your body goes through what its called "cold immersion diuresis". Kidney filters too much fluids which increases urination.This is also the theory why open water swimmer may suffer from SIPE.
