Aerobic exercise (also known as cardio) is physical exercise of relatively low intensity that depends primarily on the aerobic energy-generating process.[1] Aerobic literally means "living in air",[2] and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.[3] Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time.[1]
When practiced in this way, examples of cardiovascular/aerobic exercise are medium to long distance running/jogging, swimming, cycling, and walking, according to the first extensive research on aerobic exercise, conducted in the 1960s on over 5,000 U.S. Air Force personnel by Dr. Kenneth H. Cooper.[4][5]
Aerobic exercise and fitness can be contrasted with anaerobic exercise, of which strength training and short-distance running are the most salient examples. The two types of exercise differ by the duration and intensity of muscular contractions involved, as well as by how energy is generated within the muscle.
In most conditions, anaerobic exercise is accompanied by aerobic exercises because the less efficient anaerobic metabolism must supplement the aerobic system due to energy demands that exceed the aerobic system's capacity. What is generally called aerobic exercise might be better termed "solely aerobic", because it is designed to be low-intensity enough not to generate lactate via pyruvate fermentation, so that all carbohydrate is aerobically turned into energy.
Initially during increased exertion, muscle glycogen is broken down to produce glucose, which undergoes glycolysis producing pyruvate which then reacts with oxygen (Krebs cycle) to produce carbon dioxide and water and releases energy. If there is a shortage of oxygen (anaerobic exercise, explosive movements), carbohydrate is consumed more rapidly because the pyruvate ferments into lactate. If the intensity of the exercise exceeds the rate with which the cardiovascular system can supply muscles with oxygen, it results in buildup of lactate and quickly makes it impossible to continue the exercise. Unpleasant effects of lactate buildup initially include the burning sensation in the muscles, and may eventually include nausea and even vomiting if the exercise is continued without allowing lactate to clear from the bloodstream.
As glycogen levels in the muscle begin to fall, glucose is released into the bloodstream by the liver, and fat metabolism is increased so that it can fuel the aerobic pathways. Aerobic exercise may be fueled by glycogen reserves, fat reserves, or a combination of both, depending on the intensity. Prolonged moderate-level aerobic exercise at 65% VO2 max (the heart rate of 150 bpm for a 30-year-old human) results in the maximum contribution of fat to the total energy expenditure. At this level, fat may contribute 40% to 60% of total, depending on the duration of the exercise. Vigorous exercise above 75% VO2max (160 bpm) primarily burns glycogen.[6][7]
Major muscles in a rested, untrained human typically contain enough energy for about 2 hours of vigorous exercise. Exhaustion of glycogen is a major cause of what marathon runners call "hitting the wall". Training, lower intensity levels, and carbohydrate loading may allow postponement of the onset of exhaustion beyond 4 hours.[7]
Aerobic exercise comprises innumerable forms. In general, it is performed at a moderate level of intensity over a relatively long period of time. For example, running a long distance at a moderate pace is an aerobic exercise, but sprinting is not. Playing singles tennis, with near-continuous motion, is generally considered aerobic activity, while golf or two person team tennis, with brief bursts of activity punctuated by more frequent breaks, may not be predominantly aerobic. Some sports are thus inherently "aerobic", while other aerobic exercises, such as fartlek training or aerobic dance classes, are designed specifically to improve aerobic capacity and fitness. It is most common for aerobic exercises to involve the leg muscles, primarily or exclusively. There are some exceptions. For example, rowing to distances of 2,000m or more is an aerobic sport that exercises several major muscle groups, including those of the legs, abdominals, chest, and arms. Common kettlebell exercises combine aerobic and anaerobic aspects.
Among the recognized benefits of doing regular aerobic exercise are:
As a result, aerobic exercise can reduce the risk of death due to cardiovascular problems. In addition, high-impact aerobic activities (such as jogging or using a skipping rope) can stimulate bone growth, as well as reduce the risk of osteoporosis for both men and women.

Michelin restaurant guide: an alternative scoring system

Early on
* Unless you're very lucky, house apritifs are invariably coloured nuclear orange, the result of mixing concentrated apricot juice with the cheapest sparkling wine. A scotch is always preferable. I really don't know why Michelin never mentions this.
* Menu descriptions longer than the meal itself, tending to imply that the chef is a poet and sage: these are to be proscribed, unless the exponent is the incomparable Christian Sinicropi of the Palme-d'Or restaurant in Cannes. In a land of impenetrable philosophers - Descartes, Sartre, Cantona - Mr Sinicropi remains the least penetrable of all. His menu texts wrap themselves around each other into a sort of zenith of incomprehensibility. Thus, from his autumn menu : "A dimension of emotion, of sharing, of palliative exchanges superimposed on an initial approach with a title of nobility in two, three or four phases." In the presence of such genius, one can but genuflect. But other, lesser talents, aiming for incomprehensibility, remain all-too-comprehensible. Thus it is that we shall deduct points for each menu use of (the French versions of) "symphony", "harmony", "ethereal", "sublime" and any other terms suggesting we're in for an apparition of the Virgin Mary rather than a meal. Points are also lost for all references to "the hills and valleys of our region", "traditional peasant practices", and "long-forgotten vegetables".
* "Oven-roasted " and "pan-fried" are obvious points losers. (Where do you expect to roast and fry? In the car boot?)
* Nor do we need to know the name and address of the fellow who supplied the goats' cheese. We're not here to make friends with cheese producers.
Wine
* It is time to state the obvious: being a sommelier is not a serious job. It is not a job at all. It is simply affectation in an apron. The only people interested in a sommelier's services will know much about wine already. They'll be more determined to show off their own knowledge than listen to a wine waiter. Everyone else will go for the second-cheapest on the list, whatever happens. Wine lists longer than David Copperfield are a damned nuisance, and wines over 50 an irrelevance in almost all cases.
* Nor does anyone really want to talk about how the mineral fruitiness of the merlot teases out the marrowy nuances of the cte-de-boeuf. They want to talk about soccer, sex and shopping. So - sommelier: skedaddle. Your presence is losing vital points.
* And it's losing more yet if you are in the habit of serving the wine, then placing the bottle in a stand or on a nearby table just beyond the reach of the diners. This means they're dependent on you for re-fills - which may help you occupy those dead moments between clocking on and knocking off - but drives them either witless or to wrench a shoulder. If people are rich enough to eat in your restaurant, they can handle the wine.
