At what beats per minute (BPM) do Fine Motor Skills typically become affected?

Fine motor skills are generally impacted when an individual's heart rate reaches around 115 beats per minute (BPM). At this level of heart rate, the body begins to experience physiological changes due to stress or heightened arousal, which can affect coordination, dexterity, and the ability to perform precise movements. This is relevant in high-stakes situations, such as those encountered in law enforcement or self-defense scenarios, where maintaining fine motor control is essential for effective response. Understanding that fine motor skills begin to deteriorate around this heart rate can help individuals anticipate their physical capabilities during a stressful encounter and prepare accordingly.
