As stated in a previous blog, there are a number of limitations of cardiovascular training. One in particular being, change in atmospheric pressure due to altitude. As altitude rises, atmospheric pressure decreases, which in turn impair the respiratory system. The percentage of the different components of air we breathe (oxygen, nitrogen, and carbon dioxide) are the same at sea level and at altitude, the only thing that changes is that the air is less dense. The decrease in air density causes there to be fewer molecules of gas in each liter of air. The change in partial pressure is also caused by the increase in altitude which in turn has an effect on hemoglobin and oxygen transport. 2
As stated in a previous blog, one of the limitations of oxygen uptake was the amount of oxygen the respiratory system can utilize during high intensity workouts. Adding higher altitude to this problem gives the situation even more limitations. Altitude initially causes an increase in pulmonary ventilation, an increase in cardiac output, and a decrease in VO2max when exercising. Knowing the importance of a training athletes VO2max, we know traveling to high altitudes would be detrimental to training, or would it?1

After a three to six-month acclimatization period, the body naturally adjusts to altitude hypoxia and adaptations that could benefit training occur. There are longer-term adjustments that happen after the initial acclimatization period that can benefit an athlete's training program and performance. An increase in red blood cell production, increase in hematocrit level, an increased capillary density of skeletal muscles, and an increase in number of mitochondria. Which all of these things can lead to an increase in maximum oxygen consumption. The benefits of these are very similar to the benefits of blood doping, but are conversely an ethical ergogenic aid.1

This information on altitude adaptation on oxygen consumption is very useful for athletes trying to get an edge in competition, but there are some drawbacks. When the athlete trains at a high altitude and gains the benefits of altitude training and returns back to sea level, the adaptations will slowly revert back to pre-exposure of high altitude.2 Within weeks to months, the athlete will have lost the advantages and will be back to the level of performance he was before, or even below that due to the fact that the amount of training volume is limited because of the change in altitude.1 This, of course, led to the want to harvest those benefits without the drawbacks. Some of the training methods that accomplish that task will be discussed in the next blog.

I was able to overcome senile dementia via a complete naturopathic process.
ReplyDeleteAbout two years ago, when I was 56, I started feeling foggy and had occasional memory lapses. My wife, Mary, started to notice it, too, but I also have hearing issues so she thought that was the problem. My memory worsened very gradually over the years, and we lived with it, compensating as needed. I became less social. After some months thereafter, it got to the point where we couldn’t keep making excuses or ignoring it. I had gone from doing our grocery shopping without a list to going with a list, to having the list but not buying what was on it.
Mary went online to do some research, and it was during this process we had been fortunate enough to come across Dr. Utu Herbal Cure: an African herbalist and witch doctor whose professional works had majored on the eradication of certain viral conditions, especially dementia, ( improving the memory capacity positively), via a traditional, naturopathic process and distinguished diet plan. It was by the administration of this herbal specialist that I had been able to improve my condition for better. So to say, the encounter with the above-mentioned herbal practitioner was the first time we ever heard there was something that possibly can be done to improve my memory functionality.
By the existence of such an encounter, I was able to learn of the new approach by which this herbalist successfully treated dementia conditions, which included a distinguished herbal therapy and lifestyle changes of which I had undergone to a tremendous, positive effect.
It was after the completion of the herbal therapy I had started to experience a great deal of cognitive improvement when it came to rational decision making.
In brief, I was able to go through the dreadful hollows of senile dementia without any further hazardous damage to my health condition, and within a short period. Had it not been for the support of my wife, of whom had encouraged me to undergo the above-mentioned therapy and that of the herbal practitioner of whom now happens to be benefactor - I would have been long exposed to the further perils of this condition and of which had been apt to result to a calamitous end.
I would also wish for the same positiveness upon patients who may happen to be suffering from this debilitating disease, and would warmly beseech them to find a confidant like this herbal specialist with whose professional service I was able to attain a divine recovery.
