Correct & Verified
How does sleep affect recovery and athletic performance?
✔✔ It promotes muscle repair, hormone regulation, and cognitive function.
What is the role of carbohydrates in an athlete’s diet?
✔✔ They provide quick energy for high-intensity workouts.
Why should static stretching be avoided before explosive activities (e.g., sprinting)?
✔✔ It may temporarily reduce muscle power and reaction time.
What is DOMS, and how can it be managed?
✔✔ Delayed Onset Muscle Soreness; managed with light activity, hydration, and rest.
How does breathing technique affect weightlifting performance?
✔✔ Proper bracing (e.g., Valsalva maneuver) stabilizes the core for heavy lifts.
1
,What is the purpose of periodization in training programs?
✔✔ To systematically vary intensity/volume to prevent plateaus and overtraining.
Why is protein intake critical post-workout?
✔✔ It aids muscle protein synthesis and recovery.
What is the difference between aerobic and anaerobic exercise?
✔✔ Aerobic uses oxygen for sustained energy; anaerobic is short, high-intensity bursts.
How does dehydration affect reaction time and coordination?
✔✔ Even mild dehydration impairs focus, speed, and motor skills.
What is the "talk test" for measuring exercise intensity?
✔✔ If you can speak comfortably, you’re likely in a moderate-intensity zone.
Why is proper footwear important for injury prevention?
✔✔ It supports alignment, absorbs impact, and reduces joint stress.
2
,What is the recommended rest time between sets for hypertrophy (muscle growth)?
✔✔ 30–90 seconds to balance fatigue and volume.
How does stress impact physical performance?
✔✔ Chronic stress raises cortisol, impairing recovery and immune function.
What is the "overload principle" in fitness?
✔✔ Gradually increasing demands on the body to drive adaptation.
Why is core strength vital for overall athleticism?
✔✔ It stabilizes the spine and transfers force between upper/lower body.
What are signs of overtraining syndrome?
✔✔ Fatigue, performance decline, irritability, and frequent illness.
How does flexibility training benefit non-flexibility sports (e.g., weightlifting)?
✔✔ It improves range of motion, reducing injury risk and enhancing technique.
3
, What is the role of electrolytes during prolonged exercise?
✔✔ They maintain nerve/muscle function and fluid balance (e.g., sodium, potassium).
What is the primary goal of a dynamic warm-up before exercise?
✔✔ To increase blood flow, flexibility, and prepare muscles/joints for movement.
How does proper hydration impact athletic performance?
✔✔ It maintains electrolyte balance, prevents cramps, and optimizes endurance.
What is the difference between muscular strength and muscular endurance?
✔✔ Strength = max force in one effort; endurance = repeated contractions over time.
Why is cooldown important after intense physical activity?
✔✔ It gradually lowers heart rate and prevents blood pooling in muscles.
What are the key components of the FITT principle for exercise programming?
✔✔ Frequency, Intensity, Time, and Type of activity.
