HPER 435 Quiz 2B - Questions and Answers A type I muscle fiber is called a slow-twitch red fiber. Which of the following hormones is involved in reducing the amount of glucose in the blood in reaction to hyperglycemia? Insulin One gram of fat yields _______ Calories. 9 The technique of carbohydrate loading is effective primarily for which type of athletic events? long endurance events like marathons and long triathlons The immediate source of energy for all body processes, including muscle contraction, is adenosine triphosphate. Drag the class of nutrient to its corresponding energy-yielding or non-energy-yielding category. yielding: carbohydrate, protein, fat non-yielding: water, vitamins, minerals Which energy system would predominate in an all-out, high-intensity, 100-meter dash in track? ATP-PC (phosphagen) The greatest total amount of carbohydrate stored in the body is in the form of muscle glycogen. The main energy source for the lactic acid system during exercise is carbohydrates. Because animals store glycogen in their muscles, eating meat, fish, and poultry is a good source of carbohydrate because you are eating the dead animal's stored glucose.

During anaerobic cell metabolism, athletes sometimes complain of short-term muscle fatigue. What can be causing this fatigue? Check all that apply: 1. Lactic acid accumulating in the muscle cells increases acidity of the muscle, which inhibits the activity of some enzymes, causing fatigue. 2. Acidity in muscle cells increases potassium loss from muscles, causing fatigue. Approximately how many Calories will a 150-pound individual use while jogging a mile? 110 Which one of the following statements about fatigue is true? The most important factor in the prevention of fatigue during exercise is training Carbohydrates are an important macronutrient for fueling muscles. During exercise, where can the body get carbohydrate? Check all that apply: 1. Carbohydrate can come from glycogen stored in the muscle cells. 2.
