What training stage focuses on sport-specific training and ongoing fitness development for individuals aged 15-18?

The training stage that focuses on sport-specific training and ongoing fitness development for individuals aged 15-18 is "Training to Compete." At this stage, athletes typically engage in more specialized practices, aimed at refining their skills and preparing for competition. This period emphasizes the importance of sport-specific techniques and strategies, as well as performance enhancement through fitness training.

During this developmental phase, athletes are usually involved in competitive environments where they can apply their skills and gain experience. The focus shifts from general physical development to honing specific abilities related to their chosen sport, creating a foundation that is crucial for future success in competitions. Moreover, ongoing fitness development is essential during this age, as it helps athletes to build endurance, strength, agility, and other performance-related attributes that are integral for competing at higher levels.

In contrast, the other options pertain to different stages of athletic development. For instance, the "FUNdamentals" stage is focused on developing basic motor skills and introducing sports in a fun and engaging manner. "Long-term athletic development" refers to a broader framework that encompasses all stages of an athlete's growth, while "Training to Train" usually emphasizes building a foundation of fitness and skills prior to engaging in competitive sport-specific training.
