What is defined as the lapse of time between muscular movement and external stimuli?

The term describing the lapse of time between muscular movement and external stimuli is known as reaction time. This is a crucial component of skill-related fitness, as it measures how quickly an individual can respond to external events or stimuli. A shorter reaction time indicates a more efficient nervous system and is vital in many sports and physical activities where quick responses are essential for performance, such as in sprinting, catching, or other fast-paced sports.

Improving reaction time can lead to better performance in various physical tasks, as it allows individuals to react more promptly to changes in their environment, making them more effective in competitive situations. Hence, understanding and developing reaction time is important for athletes and those seeking to enhance their overall physical capabilities.
