Balancing Speed and Accuracy: The Impact of Breathing Frequency on Fine and Gross Motor Tasks

<b>Background:</b> Achieving a balance between speed and accuracy is crucial for optimal motor performance in sports and professional settings. However, rapid movements often compromise accuracy, a phenomenon known as the speed-accuracy trade-off, which can be measured using Fitts' Law. Emotional state also influences motor performance, particularly arousal levels, which may vary depending on task type (fine vs. gross motor tasks). Arousal regulation techniques like breath control may help optimize performance in speed-accuracy tasks. <b>Purpose:</b> This study examined the effects of breathing frequencies on the speed-accuracy trade-off in fine and gross motor tasks. <b>Methods:</b> Using a repeated-measures design, 44 participants completed two motor tasks under three breathing conditions (normal, slow, and fast), with condition and task order randomly counterbalanced. The fine motor task was performed on an iPad, while the gross motor task used a Smart Board. <b>Results:</b> The results revealed significant effects of breathing rate and task type but no interaction. Slow breathing led to less performance variability and lower arousal than fast breathing. As task difficulty increased, response times increased more in gross motor tasks. Fine motor tasks showed slower baseline average reaction times. Gross motor tasks also heightened arousal and stress levels. <b>Conclusion:</b> This aligns with previous research suggesting that slow breathing enhances autonomic regulation, improves motor performance consistency, and influences arousal. The findings of this study contribute to our understanding of how breathing frequencies can positively impact performers across diverse tasks that require precise and swift decision-making.
