To determine which activity will best help Yoko become a faster runner by developing her speed, we'll consider the overall characteristics of each activity in the list:
1. Bicycling: This activity primarily focuses on endurance and leg strength. While it does contribute to cardiovascular fitness, it may not directly translate to running speed as it uses different muscle groups and motion than running.
2. Swimming: Swimming is an excellent cardiovascular workout that enhances overall fitness and endurance. However, it predominantly uses the upper body and core, which might not fully align with the specific muscles used for running speed.
3. Gymnastics: Gymnastics builds strength, flexibility, and balance but does not focus heavily on speed in the same context as running; it's more about precision and control.
4. Soccer: Soccer is a sport that involves a great deal of running, often in short, intense bursts followed by periods of active recovery. This pattern helps develop both speed and endurance. The frequent sprints, changes in direction, and high intensity match the requirements needed for enhancing running speed.
Given these considerations, the activity that best supports Yoko in becoming a faster runner is:
Soccer
