Nutrition in Mountain Biking I. Waterworld 1. Muscles produce 30-100 times more heat while riding 2. Water doesn't supply calories, minerals, or vitamins A. But it is used for almost every body function B. 55-65% of body weight is water 3. When losing a quart of fluid heart beats 8 more times a minute 4. Before a long ride start hyperhydrating 1 day in advance 5. Do drinking strategies during your training II. Rehydrate 1. Drink alot after a ride 2. Sports drinks replenish the best 3. Eat alot of salty snacks A. Sodium makes your blood like a sponge B. meals contain more sodium naturally than sports bars III. Diet helps 1. 60% of your daily fluid comes from food 2. Fruit and vegatables are great fluid sources 3. Foods high in fat do not provide to much fluid IV. Equipment 1. Warm up bikes are good for bad weather or the dark 2. Good for intense intervals V. Liquids 1. Replenish your self after rides 2. As soon as the rides over is the best time to replenish 3. Drink or eat 100 grams of carbo 4. Drinking carbo is much faster than eating carbo 5. You can spend over $1000 a year on recovery drinks VI. Cereal 1. Flakes are carbo rich, low in fat, and quickly digested 2. Sugar coated are not bad either 3. Most cereals contain less than 2 grams of fat per serving When riding a bicycle, your muscles produce 30-100 times more heat than when your body is at rest. The body puts out this inferno by increasing the sweat rates. In the summer you can lose over two liters of fluid per hour on a really hot day, dehydration and saddle soars are the leading reasons cyclists drop out of races. The body loses this much fluid mostly from an increase in sweat rates. Water does not supply calories, minerals, or vitamins, but it is mandatory almost for every body function. It keeps body temperatures from rising while the person is exercising. Water accounts for 55-65% of your body weight. Cyclist that lose over a quart rate, which goes up to eight beats per minute a decrease in cardiac function, and an increase in body temperature. This is a study by Edward Coyle Ph.D. Director of the Humane Performance Laboratory at the University of Texas (Walsh 92). Dehydration can possibly increase metabolic stress on muscles. It also causes problems on your internal thermostat by decreasing blood flow to the skin, slowing sweat rate... ... middle of paper ... ...ients (Walsh 82). Even the fattest flakes are skinny compared to sausage or French toast. Most cereals contain less than 2 grams of fat per serving. Pudgy cereals would be those with more than three grams of fat per serving these generally include granola, and flaked cereal with nuts (Walsh 82). The competitive sport of mountain biking is making its way to the United States. The sport which was mainly held in Europe, has come to the United States and beginning to draw a heap of notable foreign competitors. According to most estimates, cycling is the most popular spectator sport in the world, just behind soccer. The mountain bike is having improvements made to everyday, and people are willing to spend the money to get the best bike (Comptons Interactive Encyclopedia).

How might the body immediately begin to reduce those avenues of water loss in Question #4? What important physiological reflexes would minimize the rate of water loss from those specific avenues?
results in the need for more blood. Since more blood is needed to fill the
amount of fat they consume on a daily basis thus causing the person to lose
-- Most of the weight you lose is not fat, it is more in the form of water and muscle
The first step to begin carb cycling is to understand what carbohydrates are and what they do for the body nutrition wise and how they affect one’s endurance. Carbohydrates replenish the body’s glycogen (Fass). Glycogen stores the carbohydrates consumed and helps prevent fatigue, muscle cramps and more (Coleman). Carbohydrates are also a main source of energy for the body
Sympathetic pathways change nerve activity during times of stress, exercise, low blood glucose levels, excitement or fear, due to the flight or fight response. These changes can have an effect on homeostasis by increasing heart rate, increasing blood flow, dilating pupils, sweating, releasing glycogen, increasing oxygen intake and diverting blood flow away from the gastrointestinal tract.
The Carb Lovers Diet is told to make you get slimmer by eating carbs. But you have to eat the right carbohydrates, the resistant starch. Bread, cereal, pasta, bananas and potato chips are resistant starch. These carbs makes you feel fuller for a longer time which will make you eat less. Other carbs that are included in this die are lentils, garbanzo beans and brown rice. Those carbs does not get transformed into glucose. There have been studies that show that if you eat breakfast that includes these resistant starches, you will burn 25% more calories per day.
The human body is estimated to be about 60 to 70 percent water. Blood, as well as your muscles, lungs, and brain all contain a high percentage of water. Water is extremely important and essential to our health (Kaushik, Mullee, Bryant, Hill, 2007). Dehydration is one of the most common side effects of not consuming enough w...

Two thirds of the human body, including an athlete's body, is made up of water. Without water we can not live, nor would we exist. Water needs to be purified in order to be drinkable and safe for humanity. Most athlete's drink high quality purified water which promotes their hydration. Dehydration is the result of not having water in your body. This can lead to fatigue, headaches, joint pain and other uncomfortable states in the human body which would affect an athlete's performance. A human can not spend more than three days without having water, therefore an athlete that uses more water than a normal person would have a shorter period of time because of how quickly they use the water. The average tissue in your body is made up of 50 percent
Carbohydrates provide energy for the body to function. When these carbohydrates are not eaten the body then burns its stored fat for fuel. As the body's supply of fat diminishes one begins to lose weight. Therefore, the Atkins Diet is successful at making one lose weight in the short term because carbohydrate intake is severely restricted to less than 20 grams per day and will eventually climb to about 40 grams after a few weeks. This "translates to no more than three cups of loosely packed salad or two cups of salad with two-thirds cup of certain cooked vegetables each day" (www.webmd.com). However, the body needs a certain amount of these carbohydrates and after a while of recieving them the body does not function properly. According to Gail Frank, a PhD professor of nutrition at California State University in Long Beach, "The body needs a minimum of carbohydrates for efficient and healthy functioning -- about 150 grams daily" (www.webmd.com). She states that less than 150 grams of carbohydrates disrupts the body's normal metabolic activity. Also, "the brain needs glucose to function efficiently, and it takes a long time to break down fat and protein to get to the brain," (www.webmd.com). Glucose results from carbohydrates or sugar broken down into the bloodstream; but also occurs naturally in fruits and honey. Therefore, the body needs a certain amount of good carbohydrates like fruits and vegetables to stay healthy.

The most important nutrient categories are starches, minerals, sugars, and electrolytes. Starches and minerals fit into the area of complex carbohydrates. Complex carbohydrates are polysaccharides (many sugars bonded together). Because of the multiple bonds, polysaccharides are able to store energy for later use. Simple sugars make up the other group of carbohydrates. The bonding structures of simple sugars are much less advanced that than those of complex carbohydrates. This allows for the burning of simple sugars in an athlete's body. Electrolytes are a category of their own because they are helpful to an athlete all of the time, whether energy storage or energy burning is needed.
Although juices, milk and beverages increase fluid intake but plain water is the best source. Most beverages contain some sugar, natural or added, this will have an effect on our body weight. But plain water does not contain anything t...
