Across
- 3. threshold: Point during exercise where lactate production exceeds clearance, often signaling a shift to anaerobic metabolism.
- 5. fibers: Cells within muscle tissue responsible for generating force and movement.
- 8. Period of rest or reduced activity following exercise to allow for physiological adaptations and repair.
- 13. Pertaining to the heart and lungs' ability to deliver oxygen to muscles during exercise.
- 16. Exercise that requires oxygen to meet energy demands over an extended period.
- 17. rate: Number of heartbeats per minute, often used as an indicator of exercise intensity.
- 19. Force opposing muscle contraction, often provided by weights, bands, or body weight.
- 22. Range of motion around a joint or group of joints.
- 24. rate: Rate at which the body burns calories and produces energy.
- 25. Muscle contraction where length remains constant, such as holding a static position.
- 27. expenditure: Amount of energy used by the body during physical activity.
- 28. Rate at which work is done, often measured as force multiplied by distance over time.
Down
- 1. hypertrophy: Enlargement of muscle fibers due to increased workload, commonly associated with strength training.
- 2. Exercises involving rapid stretching and contracting of muscles to increase power and explosiveness.
- 4. threshold: Intensity of exercise at which the body relies primarily on anaerobic metabolism.
- 6. State of exhaustion or reduced performance following prolonged physical activity.
- 7. Muscle contraction where tension remains constant while length changes, such as during lifting weights.
- 9. Muscle action where the muscle lengthens under tension, such as during the lowering phase of a bicep curl.
- 10. debt: Temporary oxygen deficit accumulated during intense exercise that must be repaid post-exercise.
- 11. prescription: Tailored regimen of physical activity designed to achieve specific fitness goals.11. Oxygen consumption: Rate at which oxygen is used by the body during exercise to produce energy.
- 12. Muscle action where the muscle shortens under tension, such as during the lifting phase of a bicep curl.
- 14. Chemical processes within the body that convert food into energy and other substances.
- 15. Physiological changes that occur in response to exercise training to improve performance and efficiency.
- 18. Ability to sustain physical activity over time without fatigue.
- 20. Storage form of glucose in muscles and the liver, used as a fuel source during exercise.
- 21. Increase in muscle size due to increased workload or resistance training.
- 23. Intense exercise performed without the need for oxygen for short bursts of energy. VO2 max: Maximum oxygen consumption during exercise, indicating aerobic capacity.
- 26. training: Physical activity aimed at increasing muscle strength, often involving resistance exercises.
