Nausea and vomiting: mechanisms of biological defense
Vomiting is a symptom that can have many causes
Vomiting or emesis is the violent expulsion from the mouth of the gastrointestinal contents, is usually preceded by nausea. To follow the nausea vomiting due to the vigorous contraction of the diaphragm and abdominal muscles responsible for the expulsion of stomach contents. Usually the vomiting is accompanied by other symptoms such as hypersalivation
·
· pallor
· Increased sweating
Vomiting is a symptom that can have many causes, some of which are linked to a function of defense In fact, the ingestion of dangerous substances (drugs, poisons, etc.) or foreign bodies may lead to the rejection should be seen as an attempt by the body to expel what it can do harm.
ADRENALIN
Vomiting during travel or in the hours following may be several possible explanations. One possible cause of this defensive mechanism is caused by blocking the digestive state of stress generated by an intense and prolonged effort like that of a race. When stress is intense, the increased production of certain hormones such as adrenaline, noradrenaline and cortisol makes it impossible to continue the digestion, the first two hormones (adrenaline and noradrenaline) involved in the adrenergic response called "fight or flight." As you might guess by its name, this reaction is designed to prepare the body to a physical and mental effort makes one feel important to the 'nervous system digestive system, "the presence of something that could be harmful in that moment and it is better to get rid of.
The sense of nausea or vomiting occurs right in the final stretch of a race where he usually tries to keep the pace early in the race thus leading to a growing accumulation of lactic acid. A high concentration of lactic acid accumulated during the athletic effort could provoke a feeling of nausea or vomiting as a significant contributing cause blood acidity.
Physical activity can influence the length of stay in the stomach food and beverage industry. Just think of the two hormones increase during the race (adrenaline and noradrenaline) that allow the body to react to stress resulting in increased cardiac output, thus increasing the amount of blood to the muscles and lungs at the expense of the digestive process. If you vomit the food material means that digestion is not fully completed, the body tries to vomit gastric emptying to send more blood to muscles, which at that time have an infinite need, rescuing it from the stomach has so-called stealing of blood from the digestive tract to the muscles. The body blocks the digestion with gastric emptying to find additional blood send to the muscles. In addition, the nausea can be caused a sharp fall in blood pressure accompanied by dizziness, weak legs and my stomach.
TIME OF DIGESTION OF FOODS
Minutes
Food
Up to 30 '
Glucose, fructose, honey, alcohol, electrolyte isotonic drinks
30' - 60 '
Tea, coffee, skim milk, lemonade
60' - 120 '
milk, cottage cheese, white bread, baked fish, mashed potatoes
120' - 180 '
lean meat, pasta, omelettes
180' - 240 '
cheese, lettuce, ham, tenderloin to Grilled
240 '- 300'
grilled steak, pies, roasts, lentils
360 '
tuna in oil, cucumbers, fried mushrooms
480'
sauerkraut cabbage sardine oil
It 'important to leave for a race or a workout always on an empty stomach with digestion in a fully completed and with full stocks. Many athletes think that is enough to digest a breakfast half an hour, but you need three or four hours. In the race restricted to only drink water never ingest any kind of supplement or would-be triggered just another digestive process by subtracting horsepower to your engine, the muscles.

Cruisy Spots Columbus Ohio
In July I participated in three events this season UISP.
The first race I attended was the 5000 meters in track, which was held in Pavia in Campo Coni. I have traveled in the 5000 meters at the rate of 22'03''4'25''. The race was held in the morning and the heat was absurd, as I came to this meeting a bit 'untrained. In this race I started too fast under 4'00'', and finished the race in distress.
The second race was held in Beresford had a length of 5.7km. The circuit always had mixed national-dirt difficulties, the umber of flies present and for the very sandy soil immediately in the first km. This resulted in a big cloud of dust raised by the runners. Even in this race I started too fast, under 4'00''and then slow down and get it to the finish line in 26'24''affannno in the average rate of 4'38''.
The third race I attended was to Roncaro. 6.35km long circuit. Finally a decent race, they have maintained a more or less constant retum along the first mile to about 4'10'', then in the central part of the race I recovered a bit 'and then accelerate nell'ultmo km, closing the race in 27'44'' the average pace of 4'22''.
Below the graph of kilometers covered in the last year.

Different Forms Of Brownies
Running Races in July in the early morning of May
the early morning, fasting, our body has enough energy to run or is essential to consume before breakfast?
During an overnight fast part of the liver glycogen (sugar stored in the liver) is consumed to maintain blood glucose levels constant, whereas muscle glycogen is not completely eroded.
If the power that follows is appropriate to your caloric intake in the morning you still have sufficient glycogen stores to run quietly an hour (who is well trained to two hours) without experiencing any loss of energy. Stress
more important (for a healthy person) is not so much physical, but it's more of a psychological nature: some are not able to get used to running in the morning even after months of trying, for others a few weeks, getting up out of bed and go running on an empty stomach is perfectly natural and very pleasant.
How to get used?
Assuming that you have already used to run at other times (who hardly begins to run from scratch it does in the morning) to get used to playing sports in the morning without too much trauma is good to follow the following steps:
• If the goal is to get up an hour earlier than usual to get the time to run, takes some getting used to initially set the alarm clock an hour earlier ( without going to run). Doing so may give the race a stress that it depends only on the alarm clock early. When it is natural to get up at a certain time, then you can start running now waking hour that is used to.
• Avoid running in the morning the illusion of gaining an hour in a day "already too short" if you get up an hour earlier in the morning, you go to bed an hour earlier in the evening (otherwise we fall into the error above).
• Allow at least twenty minutes / half an 'hour since the beginning of the alarm Training. Not necessarily be a waste of time: you can wash your face (to wake), shaving (for men only, of course), begin to set the table for breakfast they will do after the race, wear clothing for running, etc..
• Be consistent and regular workouts in the morning! It is perhaps the most important advice: the first few times may be "hard" if the body is not used to be scrambled in the early morning. After a week or two when you continue to run regularly and always only in the morning, the body get used to waking up in a hurry and negative feelings disappear very quickly. Many runners, after less than a month of sports in the morning, think you just wake up the lane and can not wait to begin training.
• Perform a good warm-up: it is always important but especially when exercising in the morning. The heating and allow the muscles to move gradually from the sleep state to full efficiency.
• In winter, cover well for the first kilometers, to avoid running too fast at the beginning of heating to try and not feel the cold. As soon as you feel that you are starting to sweat, you should immediately remove the "first layer" (mesh heavy sweatshirt). If you remain covered for too long and you sweat a lot, at the time when you remove the shirt, the sweat begins to freeze on the skin "with consequences not entirely pleasant.
Breakfast before or after training?
Running is an exercise to be performed preferably on an empty stomach for the kind of movement that causes a shaking of the stomach, both for the intensity of effort that causes slow digestion (to digest also like to run , needed blood and energy).
After the race instead becomes necessary to recover the energy spent during exercise. It supplied the muscle and liver glycogen, it is necessary to consume a good breakfast rich in carbohydrates and, if necessary, supplement with a snack (eg fresh fruit) in mid-morning. It is useful to take a little 'of proteins in order to have available the necessary amino acids for muscle repair the "damaged" during the exercise. A good breakfast could be, for example, milk or yogurt + bread and jam.
Race to fasting helps you lose weight?
Running in the morning on an empty stomach helps to burn a good percentage of fat. Thanks to the long overnight fasting blood glucose levels are lowered and thus the muscles are prone to burn a mixture a little 'richer in fat and a little' less rich in carbohydrates compared to fuel that would be used at other times of the day.
This consideration must not be misleading: what matters most is the total amount of fat (and calories) you burn during exercise (see the article on the race to lose weight). The most important thing is then run as long as possible (morning or evening becomes irrelevant) in order to consume more calories as possible.

Can Court Order For Marriage Counselling
In May, I participated in three races of the circuit UISP I set for myself.
The first was the "Gambolinata" of Gambolò, 12.1km circuit that winds through Gambolò and the surrounding countryside, arriving in the moat of the castle I was able to quit the race in 57'04''average''to 4'43 at km. The race went well, the sun was slightly hazy and did not hot.
The second race was held in Sannazzaro 5.7km circuit on a course in 25'58''to mean''to 4'35 miles, was a quiet ride and the body has held up well. The only flaw reporting the track area, where at one point there was a sharp curve entering into an underworld that was poorly reported.
The third race was held in Tromello on a 10.2km circuit course in 51'23'' the average of 5'02''/ km, was a tough race, because I got tired of the race two days before and the body assigned, then the last 4km I made them at a pace slightly just to get to the bottom.
The month of June begins with a slight physical weakness, it will be the fault of the seasonal change, with results that have not been able to train, another factor is that now I have to train in the morning getting up around 6:00 and now I've made a once in May.
In the month of June in the program there are two races, but I do not know if I'll make both.
See U Later.
