Which of the following indicates correct application of expansion in kata?

The correct application of expansion in kata is exemplified by stretching and reaching out during movements. This concept emphasizes the importance of fully extending your techniques to demonstrate power, control, and precision. When practitioners engage in expansion, they project energy outward, which is a fundamental aspect of effective martial arts practice. This outward expression not only signifies strength but also helps in developing a comprehensive understanding of distance, timing, and rhythm throughout the kata.

In contrast, the other options hinder this principle. Rapid retraction of movements might demonstrate speed but lacks the necessary focus on extending and utilizing technique effectively. Limiting the scope of techniques contradicts the idea of expansion, as it restricts the dynamics of movement and does not fully exploit the potential of the techniques being performed. Avoiding contact with opponents also does not align with the fundamental nature of kata, which is designed to prepare the practitioner for real-life applications, including engagement with an opponent. Therefore, focusing on stretching and reaching is key to embodying the principle of expansion in kata.
