What situation justifies substituting mental practice for physical practice?

Substituting mental practice for physical practice is particularly justified when a student cannot physically practice. Mental practice allows individuals to engage with the sport or skill by visualizing movements, scenarios, and tactics in their mind without the need for physical exertion. This method has been shown to be beneficial in maintaining and enhancing motor skills and cognitive awareness of the task, essentially allowing the student to continue their development even in situations where physical practice isn't possible.

When physical limitations prevent a student from practicing—due to injury, illness, or other barriers—mental practice becomes a valuable tool. It enables the individual to conceptualize and refine their technique and strategy, making it a viable alternative that can contribute to overall skill retention and improvement during periods away from physical training.
