Show Sun Advocate Price, Utah Thursday September 26, 2002 3B transportation - t health and competition The bicycle is a tremendously efficient means of transportation. In fact cycling is more efficient than any other method of walking! The one billion bicydes in the world are a testament to its effectiveness. The engine for this efficient mode of transport is the human body. Because bodies are fueled by food, diet plays an important role in how the body performs. Different muscle groups and types provide the power. Genetic inheritance, intensive training, and a competitive drive help top athletes push the boundaries of endurance and speed on the bicycle. travel--includi- ng In the United States many people still consider cycling only a recreation or professional sport. But millions ofAmericans have found that cycling is a great .way to get work or get around town. Some cyclists are banding together and forming organizations and events advocating issues important to cyclists. The bicycle has had a great impact on popular culture as well In fashion, the bicycle was largely responsible for changing women's clothing in the Tate 1800s. Restrictive corsets and long dresses made way for bloomers and later trousers. It takes less energy to bicycle one mile than it takes to walk a mile. In fact, a bicycle can be up to five times more efficient than walking. When comparing the amount of calories burned in bicycling to the number of calories an automobile bums, the difference is astounding. One hundred calories can power a cyclist for three miles, but it would only power a car 280 feet (85 meters). Unlike automobiles, which require fossil fuel, cyclists are fueled by food, a renewable energy resource. The type of food a cyclist eats can affect performance. All humans require water, pro- tein, carbohydrates, fats, vita terms aerobic and anaerobic. These terms describe two ways in which muscles get eneigy. In aerobic exercise, muscles mins, and minerals to stay healthy. For top athletes, maintaining! proper balance of these nutrients is extremely important During races many cyclists will use drinks, bars, or even gels for instant en- energy source that enables musdes to contract The ability to keep exercising aerobically depenm on the deliveiy of oxygen and fuel molecules (glucose and fatty acids) to the muscles. And that depends cm circulation and respiration, provided by the heart and your lungs. When exercising anaerobi- -' cally, musdes are drawing on stores of glycogen (which is formed from glucose) and converting them to ATP. During this exieirise the type of musdes are producing energy The human body is made up , little as 2 percent of the body's fluid through sweat can adversely affect cycling performance. Athletes riding in hot conditions for extended periods need to be careful. Severe dehydration can cause heat exhaustion or heat stroke and in even in some extreme cases, death. Cyclists are instructed to drink a few cups of water before riding and then to drink often during exercise. A cyclist's legs provide the power for cycling. Muscle attached to the thighbone (femur) and the shinbone (tibia) do the majority of the work. The thighbone works like a lever and if ifs longer than your shinbone it will provide extra leverage on each stroke of the pedals. The length of a persons thighbone is deter- mined by genetics. The length of the thighbone is not the whole story, though--it takes muscles to move those bones. Thousands of thin spaghettilike fibers make up muscle tissue. These fiben receive messages from the brain, causing the fibers to contract The main muscles at work in cycling are the quadriceps and hamstrings in the upper leg, and the gastrocnemius and soleus in the calf These muscles contract in a sequence that creates the pedaling action. The quadriceps and hamstrings do most ofthe work when you ride a bicycle. It's one thing to have the brain send amiessage to the muscles, but what fuels the muscles during the thousands of contractions that occur during extended cy- cling 7 This has to do with the A draw on oxygen as well as the glucose and fatty adds carried in by the Mood to produce adenosine triphosphate or ATP.
