12PE - Energy Systems #5

Which of the following is a by-product(s) of aerobic respiration?

• carbon dioxide, water and heat

• lactate and hydrogen ions

• inorganic phosphates

• lactic acid

Which one of the following is the common term missing from both diagrams?

• carbon dioxide

• pyruvic acid

• lactic acid

• hydrogen

Based on the data, the correct work-to-rest ratio (W:R) and the dominant energy system for this game are

• 1:5 and ATP-CP system.

• 1:3 and anaerobic glycolysis.

• 3:1 and aerobic energy system.

• 5:1 and aerobic energy system.

Which of the following best represents each energy system’s contribution to rowing a 2 km race (approximately six minutes)?

• A.

• B.

• C.

• D.

Fats are the primary fuel source for energy at

• 60% of VO2 max.

• 70% of VO2 max.

• 80% of VO2 max.

• 90% of VO2 max.

The predominant energy system used during a training session depends on the

• duration of the session.

• intensity of the session.

• athlete’s training status.

• frequency of the sessions.

Which one of the following energy systems has the slowest rate of energy (ATP) production?

• ATP-CP energy system

• aerobic energy system

• lactic acid energy system

• adenosine triphosphate breakdown

Which one of the following energy systems produces the largest amount of ATP through its chemical reaction?

• ATP-CP energy system

• aerobic energy system

• lactic acid energy system

• adenosine triphosphate breakdown

What chronic adaptation is shown in the graph above?

• increased stroke volume

• decreased stroke volume

• decreased resting heart rate

• increased resting heart rate

The adaptation shown in the graph is possible because

• stroke volume increases so the heart does not need to beat as often.

• oxygen consumption increases so the heart does not need to beat as often.

• resting heart rate increases to increase the amount of oxygen delivered to the working muscles.

• stroke volume and heart rate decrease due to an increase in the efficiency of the cardiovascular system.
