I have read a few articles around the subjects and i thought the finding were interesting.
When you’ve had a hard workout you may experience muscle pain and the odd adage is telling you that this pain is caused by the buildup of lactic acid in the muscle.
DOMS is not caused by lactic acid buildup in the muscle. This is the myth that refuses to die. Within one hour after exercise, most, if not all, of the lactic acid produced is removed and recycled.
The lactic acid myth was passed fro the scientific community to mainstream because scientist genuinely believed for a long time that lactic acid was the cause of pain.
“It’s one of the classic mistakes in the history of science,” Dr. Brooks said.”
Its origins lie in a study by a Nobel laureate, Otto Meyerhof, who in the early years of the 20th century cut a frog in half and put its bottom half in a jar. The frog’s muscles had no circulation — no source of oxygen or energy.
Dr. Myerhoff gave the frog’s leg electric shocks to make the muscles contract, but after a few twitches, the muscles stopped moving. Then, when Dr. Myerhoff examined the muscles, he discovered that they were bathed in lactic acid.
A theory was born. Lack of oxygen to muscles leads to lactic acid, leads to fatigue.
So what does cause muscle pain ?
Studies show that the vast majority of pain associated with DOMS is caused by the action of stretching muscles ‘Eccentric’, in which the muscle fibers are lengthened as force is applied to them.
Lactic acid is actually a fuel. Muscles make it deliberately, producing it from glucose, and they burn it to obtain energy. The reason trained athletes can perform so hard and so long is because their intense training causes their muscles to adapt so they more readily and efficiently absorb lactic acid.
I came across an interesting post done by an American woman where she compares her experiences of the American versus the UK health system.
She makes very interesting conclusions
a)The NHS looks like a a very socialist – soviet style – health care model.
b)At least health care in the UK is not dictated to you by someone else, you are free of your own decisions. In the US insurance companies force you to do all sort of stuff
c)There are a lot of delays in the UK but just about the same as in the US
d)Thank god in the UK you can choose your own doctor.
e)You don’t receive bills from the hospital. Free means free.
f)Brits truly believe that health care is a human right and are happy to have a system that covers everyone, all the time.
e)A private system is healthy and alive in the UK. Both public and private systems can coexist.
f)Brits do not have to worry about care being tied up to employment. They don’t have to worry how they will bring health care to their family. This stimulates productivity !
g)The government answers to the people in a way that US insurance companies never do because the government has a public duty.
h)There is an emphasis on preventative care and the simplest way this happens is that people actually go to see their doctor when they are sick.
Finally the author concludes “I can sum up my experience of the British and American health care systems in one simple sentence: given a choice between the two systems, I’d choose the NHS in a heartbeat. And though this is the experience of only one single person out of millions, unlike so much of the propaganda and hysteria surrounding the current health care debate, it is the absolute Gospel truth.”
I came across this simple post about sleep quality and i thought the finding were good to repeat here. The author propose a few points of Reflexion to make sure we take care of our sleep.
In order :
a) One of the biggest mistakes people make in corrupting their sleep is to use their bedroom for activities other than sleep or sex. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high.
b) Going to sleep should be a process whereby you begin to disengage from the day to enter into sleep. Having regular (as much as humanly possible) sleep and awake times will assist with setting your sleep routine.
c) Avoid spicy food, caffeine, sugar and alcohol at least 4 to 6 hours prior to your sleep time
d) Avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
e) Establish a pre-bedtime ritual that will help focus you on sleep
I read the following article that describe the seven stages of the Alzheimer disease. I thought that was informative.
