At what heart rate does a loss of fine motor skills typically occur?

A loss of fine motor skills typically occurs at a heart rate around 115 BPM. When a person’s heart rate rises to this level, the body is under increased stress, which can affect coordination and dexterity. Fine motor skills require the brain to communicate rapidly with small muscles, particularly in the hands and fingers. Elevated heart rates can lead to decreased blood flow to extremities and changes in concentration and hand-eye coordination, making it more challenging to perform tasks that require delicate movements.

Understanding this physiological response is vital in training contexts, particularly for individuals in law enforcement or emergency situations where calm and precise actions are necessary despite physiological stress.
