Muscle pain after exercise (DOMS) is not caused by lactic acid buildup in the muscle

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.

America’s versus Britain’s Healthcare System

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.”

Take control of your sleeping patterns

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

The Seven Stages of Alzheimer’s Disease

I read the following article that describe the seven stages of the Alzheimer disease. I thought that was informative.

    Stage 1 : No noticeable cognitive impairment

  1. In earlier stages of Alzheimer’s disease, there are no visible impairment in memory or other brain functions even under close examination of a qualified physician.
  2. Stage 2 : Very mild decline in cognitive function

  3. The second stage is still early in the process, and it may not be evident to close family and friends or a doctor. It is more akin to age-related memory loss and is noticeable generally only by the one suffering from the disease. It is characterized by having trouble recalling names, places, or where belongings such as purse or house keys where last placed.
  4. Stage 3 : Mild decline in cognitive function

  5. This is really the first stage in which a diagnosis of Alzheimer’s disease can be performed. The symptoms are more pronounced, though a diagnosis may not always be possible in this stage. It is characterized by the inability to retain new information, decreased performance at work and an inability to organize or make plans. Also, memory lapses become much more pronounced and noticeable by family, friends and coworkers.
  6. Stage 4 : Moderate decline in cognitive function

  7. At this stage of Alzheimer’s disease a diagnosis is clear and steps will begin to treat the symptoms. Patients in this stage exhibit symptoms such as the inability to perform tasks such as keeping up with their finances or making any sort of complex plans. Also, some memories of personal history will be forgotten and new associations will generally not be retained.
  8. Stage 5 : Moderately severe decline in cognitive function

  9. This is considered the mid-stage of Alzheimer’s disease. Those suffering in this stage will generally require daily help with many normal activities. Memory gaps will be wider and more severe, though major information such as deep-seeded memories and knowledge of family and their names will still be recalled. However, things such as address or the date (including the month or even the season) may be forgotten on a regular basis.
  10. Stage 6 : Severe decline in cognitive function

  11. This stage of Alzheimer’s disease will result in a severe memory loss and almost complete disappearance of the awareness of the person’s immediate surroundings. Memory of close friends, family and children will have begun to fade, including their names and faces. A person in this stage may also need help with activities such as bathing and using the toilet. It is in this stage where hallucinations may begin as well as wandering away and becoming lost.
  12. Stage 7 : Very severe decline in cognitive function

  13. This is the final stage of Alzheimer’s disease where the symptoms are incredibly severe. The person suffering will no longer be able to recall any memories, though the most severe aspect of this phase is the inability of the person to communicate or physically interact with their surroundings. Virtually all aspects of their daily lives will require assistance. The ability to speak, to swallow, to smile, to walk or to sit up without some sort of support will be lost or severely impaired in this stage.
