100

This nutrient is the body’s primary quick source of energy.

What are carbohydrates?

100

This energy system is used during short, explosive efforts lasting about 5–10 seconds.

What is the Phosphagen or ATP-PC system?

100

This energy system is primarily used during a basketball fast break.

What is the phosphagen or ATP-PC system?

100

This explains why sprinters rely on short-term energy systems instead of aerobic (oxidative) metabolism.

What is the need for immediate, high-power energy?

200

This nutrient is essential for muscle repair and recovery.

What is protein?

200

This energy system produces energy without oxygen.

What is glycolytic?

200

This energy system is heavily relied on during a 400-meter race.

What is the glycolytic system?

200

This is what happens to performance when an athlete does not consume enough carbohydrates.

What is decreased energy or fatigue?

300

This nutrient provides the most energy per gram.

What are fats?

300

This energy system is dominant during long-duration, steady-state exercise.

What is oxidative?

300

This energy system is most dominant during a full soccer match.

What is the oxidative system?

300

This would be an appropriate quick fuel source before high-intensity activity.

What is a carbohydrate-rich food?

400

This process helps regulate body temperature and maintain performance during exercise

What is hydration?

400

This is the reason the ATP-PC system fatigues quickly during activity.

What is limited stored ATP and creatine phosphate?

400

This concept explains why multiple energy systems are used during most sports.

What is energy system overlap?

400

This is the most likely reason an athlete feels fatigued late in a game.

What is depleted glycogen stores (low energy)?
