What BPM threshold affects Complex Motor Skills?

Complex Motor Skills, which involve more intricate movements requiring coordination, are significantly impacted by physiological response to stress, particularly heart rate. Research indicates that when a person's heart rate rises above 145 beats per minute (BPM), their ability to perform these skills diminishes because cognitive processing and fine motor functions are impaired under higher stress conditions.

At this elevated heart rate, the body's response includes heightened adrenaline and decreased focus, leading to reduced effectiveness in executing complex tasks that require precision. Therefore, understanding this BPM threshold is crucial for training and performance in high-stress scenarios, particularly in the context of defensive tactics and law enforcement activities.
