Things You Should Know...A.A.S

Explanation
Carbohydrates should be the main source of energy in any healthy diet because they are the body's preferred source of fuel. They provide quick energy and are easily broken down into glucose, which is used by the body for various functions. Carbohydrates also provide essential nutrients such as vitamins, minerals, and fiber, which are important for overall health and digestion. Protein and fat are also important components of a healthy diet, but they should be consumed in moderation and not as the primary source of energy. Fiber, although important for digestion, does not provide the same amount of energy as carbohydrates.

Explanation
Men generally have higher muscle mass and a higher metabolic rate compared to females. Protein is essential for muscle growth, repair, and maintenance, as well as for various bodily functions. Therefore, men require more protein to support their higher muscle mass and metabolic needs. This is why the statement "Men need more protein than females" is true.

Explanation
The proper running form involves coordinating the movement of the right leg with the left arm. This is because when the right leg moves forward, the left arm swings forward and vice versa. This coordination helps maintain balance and stability while running, optimizing the efficiency of movement and reducing the risk of injury.

Explanation
Running on sand carries a higher risk of ankle sprain compared to running on grass. This is because sand is an unstable surface that provides less support and stability to the ankle joint. When running on sand, the foot sinks into the soft surface, causing the ankle to roll or twist more easily, leading to a higher risk of spraining the ankle. On the other hand, grass provides a more stable and cushioned surface, reducing the risk of ankle sprains.

Explanation
The 100m race is qualified as a sprint because it is a short-distance race that requires athletes to run at their maximum speed. Sprints are typically races that are shorter in distance and focus on explosive power and speed. The 100m race is one of the most iconic sprint events in track and field, where athletes compete to see who can cross the finish line first in the shortest amount of time.

Explanation
The lung is a vital organ that is part of the respiratory system. It plays a crucial role in breathing, especially during physical activities like running. When we run, our body requires more oxygen, and the lungs help in taking in oxygen and removing carbon dioxide from the body. The lungs expand and contract to facilitate the exchange of gases, allowing us to breathe properly while running.

Explanation
Jumping rope is considered a cardio exercise because it increases heart rate and breathing rate, thereby improving cardiovascular endurance. It involves continuous movement of the entire body, which helps to burn calories and improve overall fitness. Jumping rope also engages multiple muscle groups, including the legs, arms, and core, making it an effective full-body workout. Planks, push-ups, and lunges are strength exercises that primarily target specific muscle groups and do not provide the same cardiovascular benefits as jumping rope.

Explanation
Coconut water is considered the best way to replenish potassium while running. This is because coconut water is a natural source of electrolytes, including potassium. Potassium is an essential mineral that helps maintain proper muscle function and hydration levels. Coconut water also contains other beneficial nutrients, such as magnesium and calcium, which can further support athletic performance. Therefore, consuming coconut water during or after a run can help replace lost potassium and electrolytes, aiding in hydration and muscle recovery.

Explanation
Muscles have a larger glycogen capacity compared to the liver. Glycogen is a form of glucose storage in the body, and it is primarily stored in the liver and muscles. While the liver stores glycogen to regulate blood sugar levels and provide energy to the body, the muscles store glycogen to fuel their own activity. Since muscles are larger in mass compared to the liver, they have a greater capacity to store glycogen. This allows muscles to sustain prolonged physical activity and provide a readily available energy source during exercise.

Explanation
A relay team typically consists of four members. In relay races, each team member runs a portion of the race and then hands off a baton to the next runner. The four members work together to complete the race, with each member contributing to the team's overall performance. This is a common format in track and field events, as well as in swimming relays and other team sports.
