Swimming or standing in water for BI recovery

[RecoveringH]

Just being in chest-level deep water leads to a 14% increase in blood flow to the brain.

An article entitled The Best Swim Workouts + 8 Key Benefits of Swimming By Dr Axe may contain helpful recovery information for BI survivors.

Who is off to the swimming pool tonight for a Sunday evening paddle? I often wondered about the 80+ year olds standing around chatting in the pool at the side when I was vigorously pounding up and down doing lengths in breast stroke, butterfly and front crawl. I thought them lazy. Little did I know they were wiser than I ! ( ~:

Hi H,

I don’t fully trust Dr. Axe cos although some of the things he says might be correct, some other things are completely wrong.

I think he is a bit controversial or not well informed.

He said, in a video about vitamin B12, that you can only get this vitamin from animals.

Well I get B12 from nutritional yeast so he is obviously wrong.

I have a vegan friend who will say that all the vitamins and minerals you need come from plants.

Animals do not produce protein, they gain it.

Animals do not produce omega 3, they gain it.

Animals do not produce vitamin B12, they gain it.

Fair enough Matt. I like the diagrams and pictorials with short text for information overview. His pages are always clearly laid out in a format that I find accessible. Hope you are well and happy.

Best wishes.

I can be the same, I prefer to view pictorials/diagrams with short text info rather than read up on pages and pages of info. One, I haven't got the time to do all the reading and two, sometimes I am just not in the mood for reading as well.

The pictorials/diagrams I usually see can be found on facebook and I don't know if some of these diagrams have come straight from Dr. Axes website or from other websites.

I am very well and happy thank you :). Hope you are too :).

Ive been using swimming since soon after i left rehab. I still swim at least once a week

That sounds interesting, going to give it a try this week. Does it mention anything about the temperature?

Episodic increases in cerebrovascular perfusion and shear stress may have beneficial impacts on endothelial function that improve brain health. We hypothesized that water immersion to the level of the right atrium in humans would increase cerebral perfusion. We continuously measured, in 9 young (means ± SD, 24.6 ± 2.0 yr) healthy men, systemic hemodynamic variables along with blood flows in the common carotid and middle and posterior cerebral arteries during controlled filling and emptying of a water tank to the level of the right atrium. Mean arterial pressure (80 ± 9 vs. 91 ± 12 mmHg, P < 0.05), cardiac output (4.8 ± 0.7 vs. 5.1 ± 0.6 l/min, P < 0.05) and end-tidal carbon dioxide (PetCO2, 39.5 ± 2.0 vs. 44.4 ± 3.5 mmHg, P < 0.05) increased with water immersion, along with middle (59 ± 6 vs. 64 ± 6 cm/s, P < 0.05) and posterior cerebral artery blood flow velocities (41 ± 9 vs. 44 ± 10 cm/s, P < 0.05). These changes were reversed when the tank was emptied. Water immersion is associated with hemodynamic and PetCO2 changes, which increase cerebral blood velocities in humans. This study provides an evidence base for future studies to examine the potential additive effect of exercise in water on improving cerebrovascular health.

No mention of temperature. Just simply being immersed in water! I wonder if it matters if the body is upright or lying down? I mean, having a bath is also immersing in water! Right I'm off to do some maths in the bath! : ) haha

WOW I just found this amazingly interesting study. I wonder if Headway has seen it?

Comparison of motor skill learning, grip strength and memory recall on land and in chest-deep water.

Abstract

Immersion in chest-deep water may augment explicit memory in healthy adults however, there is limited information on how this environment might affect implicit memory or motor learning. The purpose of this study was to compare the speed and accuracy for learning a motor skill on land and in chest-deep water. Verbal word recall and grip strength were included to gain a more complete understanding of the intervention. Sixty-two younger adults (age = 23.3 ± 3.59 yrs.) were randomly assigned to either a water group immersed to the xiphoid or a land group. Participants in both groups completed the same eight practice trials of a mirror-drawing task on two separate days. Outcome measures for this task included time and error numbers to complete each drawing. The number of words recalled using a 12 word recall test, and peak grip strength using a hand dynamometer were measured each day of testing. The influence of environment and repeated practice on each outcome measure were assessed with an analysis of variance and effect sizes (ES). Time and errors for both groups significantly decreased with practice (p < 0.01, ES = 0.11-0.28), however the drawing time was greater in water than on land for trials 1, 5, and 6 (ES = 0.50-0.55). There was a 7% increase in words recalled (9.24 ± 1.19 vs 8.60 ± 1.19) and a 16% increase in grip strength (405 ± 104 vs 342 ± 83) for water than land groups (ES 0.54-0.64). Healthy adults in chest-deep water and on land display comparable mirror-drawing speed and accuracy after minimal practice. Curiously, water immersion may augment verbal word recall and grip strength abilities.

Temperature affects the location flow of blood in the body. I will be swimming in a lake and it's cold.
