Final answer:
The statement that training for a race can provide a focus when running is True. Setting specific goals such as preparing for a race can significantly enhance a runner's motivation and training efforts, but does not affect their genetic makeup.
Step-by-step explanation:
Training for a race can indeed provide a goal to focus on when running. This statement is True. When a runner has a specific goal, such as preparing for a race, it gives them a clear purpose and motivation, which can enhance their training regimen. During training, runners might focus on improving their speed, endurance, and overall fitness to achieve better performance in the race. For instance, runners may engage in various types of workouts, like interval training or long-distance runs, to target different aspects of their running abilities.
It is also interesting to mention that while natural selection produces beneficial adaptations over generations, individuals cannot change their genetics by exercising. However, they can improve their physical capabilities through consistent practice and training. Considering a scenario where Sarah is running the 5000 m and Laura is running the 10K, which is equivalent to 10000 m, Laura will have to run the longer distance. This is a mathematical comparison that can help students understand how physical preparation might vary depending on the distance of the race they're training for.
