What are the health benefits of adequate carbohydrates for athletes?

It is well documented that athletes need to replenish carbohydrate stores in the body, especially during periods of intense training or competition. Consuming carbohydrates during training sessions lasting longer than an hour can also improve performance and delay the onset of fatigue.
RECOMMENDED CARBOHYDRATES INTAKE Depending on the training routine, athletes should consume between 3 and 12 grams of carbohydrates per kilogram of body weight throughout the day. This percentage is only a guide for estimating carbohydrate requirements.
Nutrition is one of the most important components of performance training. The popular belief that sugar and carbs are bad for athletes has been debunked! Many studies show that carbs are one of the best ways for an athlete to replenish muscle glycogen stores.
Consuming carbs during workouts longer than an hour can also improve performance and delay the onset of muscle muscle fatigue. Studies have shown that athletes who play intermittent sports, such as basketball and soccer, should also focus on consuming more carbohydrates during training and competition.

A. Protein is more important than carbohydrate as an energy source for muscle activity. B. The use of protein as a source of energy is more important for endurance athletes than for those who build their bodies or lift weights.
Muscle glycogen is the main fuel for intense exercise and is a source significant amount of fuel during the first hour of exercise. of exercise. During periods of low-intensity exercise, such as a leisurely walk, blood sugar levels as well as fat stores are primarily used to produce ATP. Some of this glucose comes from the breakdown of glycogen by the liver.

What is most important as a source of energy for muscle activity?

Muscle function Muscles use the chemical energy stored in the food we eat and convert it into heat and energy for movement (kinetic energy). The source of energy used to power the contraction movement of working muscles is adenosine triphosphate (ATP), the body’s biochemical way of storing and transporting energy.
The most abundant source of energy in muscle fibers is glycogen. When glycogen is needed to provide energy for sustained contractions (longer than a few seconds), it is first broken down into the glucose molecules that make it up.
Muscle Energy Systems. To continue working, muscle cells must replenish their ATP supply. All muscle cells contain a high-energy compound, creatine phosphate, which is quickly broken down to produce ATP. Since creatine phosphate stores are also limited, this energy system can only sustain peak muscle production for about 10 seconds. need to recover. -Synthesize ATP. Carbohydrate metabolism is faster than fat metabolism.

What is the source of energy for muscle contraction?

The direct source of energy for muscle contraction is ATP. ATP, however, is not stored in large amounts in muscle fibers and is consumed within seconds. Secondary energy sources are creatine phosphate and glycogen. Creatine phosphate is, like ATP, a molecule that transfers energy.

ATP is a high-energy nucleotide that acts as an instant energy source within the cell . When muscles contract, they break down ATP in a reaction that provides energy. However, muscle cells only store enough ATP to fuel a few seconds of peak contraction. Once muscle contraction begins, ATP production should begin rapidly.

When glycogen is needed to provide energy for sustained contractions (longer than a few seconds), it is first broken down into molecules of glucose from which it is made. Glucose is then broken down in the process of cellular respiration to produce ATP, and muscle fibers can continue to contract.
Muscles have two sources of oxygen. Blood provides a continuous supply of oxygen from the lungs, which is carried by hemoglobin in red blood cells. Within the muscle fibers themselves is another protein called myoglobin, which stores oxygen in muscle cells.

What is the energy system of muscle cells?

muscular energy systems. To continue working, muscle cells must replenish their ATP supply. All muscle cells contain a high-energy compound, creatine phosphate, which is quickly broken down to produce ATP. Since creatine phosphate stores are also limited, this energy system can only sustain peak muscle production for about 10 seconds.
The muscular system is a set of body tissues with the ability to change shape. Muscle cells connect to each other and eventually to parts of the skeletal system. When muscle cells contract, a force is created as the muscles pull against the skeleton. Actin and myosin are the main proteins used in muscle cells to cause contraction.

In these cells and from these energy sources, adenosine triphosphate (ATP) is formed to provide fuel. The body uses 3 different systems to provide cells with the ATP needed to meet energy needs.

Why do muscles need carbohydrates to sustain exercise?

Role of Carbohydrates in Exercise Carbohydrates are an important source of energy during exercise. During brief intense exercise, it may be the sole source of energy for the working muscle and may come exclusively from glycogen stores in the muscle fibers themselves. During prolonged submaximal exercise, the amplitude of con…
After exercise or at rest, muscles need to repair and rebuild. Just like building muscle, protein and glycogen are necessary for muscle repair. The importance of glycogen for muscles cannot be overstated and carbohydrates are needed to maintain glycogen stores.
The main purpose of consuming carbohydrates is to provide us with energy. When we eat carbohydrates, they are digested and absorbed in the small intestine, then supply glucose to the blood. This glucose is used in the tissues for fuel or stored as glycogen in the liver and muscles.
However, if you are an athlete or do regular strenuous activity, you probably need a slightly higher carbohydrate intake than the average person. The types of carbohydrates you consume will have drastically different results in terms of energy production, total nutritional value, and effect on blood sugar.

What is the end product of aerobic and anaerobic breakdown of glucose?

B. the end product of the aerobic breakdown of glucose is lactic acid; the end products of the anaerobic breakdown of glucose are carbon dioxide and water. C. the end products of aerobic breakdown of glucose are carbon dioxide and water; the end product of the anaerobic breakdown of glucose is lactic acid. D. Anaerobic breakdown of glucose uses oxygen, while aerobic breakdown does not.
Anaerobic respiration is similar to aerobic respiration, except the process occurs without the presence of oxygen. Therefore, the by-products of this process are lactic acid and ATP.
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide and energy. All higher organisms, including mammals, have this type of respiration.
The aerobic breakdown of glucose provides most of the energy needed for sports activities lasting A. up to 30 seconds. B. 30 seconds to 1 minute. C. 1 to 2 minutes. D. 2 minutes to 4 hours.

Conclusion

The aerobic energy pathway is able to produce the most ATP of these three systems. This is largely due to the ability of this energy system to convert fats, carbohydrates, and proteins into a state that can enter the mitochondria, the site of aerobic ATP production. Physiological characteristics of marathon runners
During a race, the marathon runner uses about 75 kilograms of ATP, and since this quantity cannot be stored in the body, the ATP is resynthesized from different fuels (ie PCr, carbohydrates, lipids and proteins), with the catabolism of fuels that provide the necessary energy.
Third source of energy during a marathon: the aerobic system. The aerobic system can use carbohydrates, fats or proteins to produce energy. Power generation is slower, however, more efficient than the other two systems. As the name suggests, the aerobic system requires an adequate amount of oxygen to be delivered to the working muscles.
ATP is the only fuel that working muscles can use directly for contraction. The body has limited stores (~80-100 grams) of ATP, just enough to provide energy for two seconds of maximum running; therefore, ATP must be continuously resynthesized from other sources through different metabolic pathways.
