At what heart rate do you typically lose complex motor skills?

Complex motor skills are highly coordinated physical movements that require a good level of focus and fine motor control. As heart rate increases due to physical exertion or stress, cognitive and physical performance can be affected. Generally, complex motor skills begin to deteriorate at heart rates above a certain threshold, which is typically around 145 beats per minute.

At this point, the body's physiological response to increased heart rate can lead to diminished coordination, slower reaction times, and reduced precision. As the heart rate climbs higher, more significant impairments in these skills are likely to occur, making it essential for individuals, especially those in law enforcement or similar fields, to be aware of their physiological limits during high-stress situations. Understanding this threshold is crucial for maintaining effectiveness in tasks requiring high levels of coordination and skill.
