Question

23 multiple answer 2 points which of the following statements are true about \hitting the wall\? it sets in after 120 minutes of an endurance sports event glycogen stores are depleted characterized by extreme fatigue carbohydrate loading can prevent this from occurring drinking red bull can prevent this from happening

Explanation:

• "It sets in after 120 minutes of an endurance sports event": In endurance sports like long - distance running, "hitting the wall" typically occurs around 90 - 120 minutes into the event as glycogen stores start to deplete, so this statement is true.
• "Glycogen stores are depleted": "Hitting the wall" (also known as bonking) is mainly caused by the depletion of glycogen stores in the body, which are the main source of energy for high - intensity or prolonged endurance exercise, so this statement is true.
• "Characterized by extreme fatigue": When glycogen stores are depleted, the body has to rely more on fat metabolism (which is a slower energy - producing process), leading to a significant drop in energy levels and extreme fatigue, so this statement is true.
• "Carbohydrate loading can prevent this from occurring": Carbohydrate loading increases the glycogen stores in the body before an endurance event. With more glycogen available, the time until glycogen depletion (and thus "hitting the wall") is delayed or prevented, so this statement is true.
• "Drinking Red Bull can prevent this from happening": Red Bull is an energy drink that mainly provides a short - term boost from caffeine and sugar. It does not address the underlying issue of glycogen depletion. Once glycogen is depleted, a short - term energy boost from an energy drink will not prevent the physiological effects of "hitting the wall", so this statement is false.

Answer:

• it sets in after 120 minutes of an endurance sports event
• glycogen stores are depleted
• characterized by extreme fatigue
• carbohydrate loading can prevent this from occurring
