What is the primary genetic factor contributing to an athlete's speed?
What is the primary genetic factor contributing to an athlete's speed?
- An average percentage of both muscle types
- A high percentage of slow-twitch muscle fibers
- A low percentage of total muscle mass
- A high percentage of fast-twitch muscle fibers (correct)
How does strength training affect an athlete with fewer fast-twitch muscle fibers?
How does strength training affect an athlete with fewer fast-twitch muscle fibers?
- It allows the athlete to run slower by increasing muscle size.
- It only benefits those with a high percentage of fast-twitch muscle fibers.
- It decreases the overall muscle mass.
- It increases the force applied against the ground, improving speed. (correct)
What might a player achieve through the combination of high fast-twitch fibers and strength training?
What might a player achieve through the combination of high fast-twitch fibers and strength training?
- No change in performance metrics.
- Reduced overall speed due to fatigue.
- Significantly improved speed performance. (correct)
- Increased endurance over prolonged periods.

Study Notes
Speed in Athletes
- Speed is a crucial quality for athletes like soccer players.
- High-velocity performance (running, swimming) depends on two factors:
- Genetic inheritance: Athletes with more fast-twitch muscle fibers are faster.
- Strength training: Improves force applied to the ground, leading to faster running.
- Fast-twitch muscle fibers are linked to speed. A higher percentage (e.g., 53%) correlates to faster performance.
- Strength training is beneficial for all athletes, especially those with fewer fast-twitch fibers.
- Combining good genetics (fast-twitch fibers) with strength training maximizes speed potential.
