At what heart rate, measured in BPM, do fine motor skills begin to deteriorate?

Fine motor skills, which involve precise movements and coordination, begin to deteriorate as a person's heart rate increases due to physiological stress responses. Research indicates that this deterioration typically starts around 115 BPM. At this heart rate, individuals may experience increased adrenaline, which can lead to trembling and reduced coordination necessary for fine motor tasks. This understanding is crucial for peace officers, as it highlights the impact of stress and physical exertion on their performance and decision-making abilities during critical incidents. Maintaining awareness of one’s physiological state, including heart rate, can assist in managing stress levels and ensuring effective functioning during high-pressure situations.
