Across
- 2. – Supplement that increases high-intensity power by replenishing ATP stores.
- 5. – Breakdown of glucose to make ATP anaerobically.
- 8. – Ability of muscle cells to switch between fuel sources (carbs, fats).
- 11. – Power training using explosive throwing, jumping, or striking movements.
- 12. – Rate of motion or distance covered per unit of time.
- 15. – Muscle shortens during contraction (lifting phase).
- 16. – Sequence of exercises done one after another with short rests.
- 17. – Aerobic process that produces energy from carbohydrates, fats, and proteins.
- 20. – Muscle lengthens while under tension (lowering phase).
- 22. – Maximum oxygen uptake; a measure of aerobic capacity.
- 23. – “Speed-play” method mixing steady exercise with bursts of faster effort.
- 24. – A motor neuron and all the muscle fibers it controls.

Down
- 1. – Exercise that alternates intense effort with rest or low activity.
- 3. – Amino acid supplement that buffers acid buildup during intense exercise.
- 4. – Individual muscle cell capable of contraction.
- 6. – Unit that estimates energy cost of physical activity.
- 7. – 30-second all-out cycling test for anaerobic power.
- 9. – Rate at which energy is transferred; force times distance divided by time.
- 10. – Exercises using quick stretch–shorten actions to build power.
- 13. – Total volume or intensity of training performed.
- 14. – Combining multiple sports or exercise types to enhance performance.
- 18. – The threadlike structure inside muscle fibers that contracts.
- 19. – The push or pull exerted on an object.
- 21. – Enzymes that support aerobic energy production.
