During high endurance activities, the primary muscles used are predominantly slow-twitch muscle fibers, found in muscles like the quadriceps, hamstrings, and calves for lower body activities, and the deltoids and pectorals for upper body movements. These fibers are more fatigue-resistant and are designed for prolonged activity, utilizing aerobic metabolism to efficiently produce energy. Endurance activities also engage core muscles to stabilize the body and maintain posture over extended periods. Overall, the key muscle groups are those that support sustained, rhythmic movements.

What is high endurance?
Endurance refers to the amount of stress, activity, and exersize your body is capable of handling. High endurance indicates that said body can handle a lot more activity than most. Your endurance is a reflection of how active you are - the more you exersize and remain active, the more your body will become accustom to it, and your endurance will increase. Eventually, living an active, healthy life, you will notice that you have achieved high endurance.
Is cardiovascular endurance the ability to perform short duration high intensity exercise?
false
How do muscles get energy during high levels of activity?
Fermentation
What is Anaerobic exericse A.an exercise that uses special machines that provide resistance and control the speed of contraction within the range of motion. B.any physical activity that is short?
Anaerobic exercise refers to any physical activity that is short in duration and high in intensity, where the body's demand for oxygen exceeds the oxygen supply available. This type of exercise includes activities like weightlifting, sprinting, and high-intensity interval training (HIIT), which primarily rely on energy sources stored in the muscles rather than oxygen. It helps build muscle strength, power, and endurance.
Why does long distance runners need cv endurance?
Long-distance runners require cardiovascular (CV) endurance to sustain prolonged physical activity without excessive fatigue. High CV endurance allows them to efficiently deliver oxygen to their muscles and remove waste products, which is crucial for maintaining performance over extended periods. This endurance helps prevent early onset of fatigue, enabling runners to maintain their pace and improve overall race times. Additionally, strong CV endurance contributes to better recovery and reduced risk of injury.
Why does a trampolinist need cardivascular endurance?
A trampolinist requires cardiovascular endurance to maintain high energy levels throughout their routines, allowing them to perform complex aerial maneuvers without fatigue. This endurance supports sustained physical activity, enabling them to recover quickly between jumps and maintain optimal performance. Additionally, a well-conditioned cardiovascular system helps manage oxygen supply to the muscles, enhancing overall agility and coordination during routines.
How is glycogen loading achieved?
Glycogen loading, also known as carbohydrate loading, is achieved by increasing glycogen stores in the muscles through a combination of tapering exercise, reducing training intensity, and consuming a high-carbohydrate diet leading up to an event. This process helps improve endurance performance by ensuring the muscles have more fuel available for prolonged activity.
How do your muscles continue to get energy during high levels of activity when there is not enough energy?
The muscles continue to get enough energy during high levels of activity when there is not enough oxygen through the absorption of water. It is a good idea to drink water frequently when doing strenuous exercise.
What are the thress types of muscle fibers and how does each affect muscles strength and endurance?
The three types of muscle fibers are Type I (slow-twitch), Type IIa (fast-twitch oxidative), and Type IIb (fast-twitch glycolytic). Type I fibers are endurance-oriented, providing sustained energy for long-duration activities but less strength. Type IIa fibers offer a balance of strength and endurance, suitable for activities requiring both. Type IIb fibers are geared for high-intensity, short-duration bursts of strength but fatigue quickly, making them less effective for prolonged exertion.
Is a hurdler anaerobic or aerobic?
A hurdler primarily relies on anaerobic energy systems during their event. Hurdling involves short bursts of intense activity, requiring quick, explosive movements for sprinting and jumping over hurdles, which are fueled by anaerobic processes. While aerobic fitness is important for overall endurance, the short duration and high intensity of hurdling make it predominantly an anaerobic activity.
Why do our muscles need lots of mitochondria within their cells?
Muscles require a high number of mitochondria within their cells to efficiently produce adenosine triphosphate (ATP), the primary energy currency of the cell. Mitochondria generate ATP through aerobic respiration, which is crucial during prolonged or intense physical activity. This energy production supports muscle contraction and endurance, allowing muscles to perform optimally and sustain activity over time. Additionally, more mitochondria enhance the muscle's ability to utilize oxygen and metabolize fats and carbohydrates for energy.
Using carbo-loading to increase the store of glycogen seems to benefit only those athletes who engage in aerobic activities that are?
Carbo-loading primarily benefits endurance athletes who participate in prolonged aerobic activities, such as long-distance running, cycling, or swimming. This strategy enhances glycogen stores in muscles, delaying fatigue and improving performance during extended efforts. However, it may not significantly impact athletes involved in shorter, high-intensity or anaerobic activities, where glycogen depletion occurs over a shorter duration. Thus, the effectiveness of carbo-loading is closely tied to the duration and intensity of the activity.
