Competition of internal and external information in an exercise setting

Area of Science:

• Psychology of Exercise
• Human Perception
• Cognitive Neuroscience

Background:

• Physical exercise involves competing internal and external sensory cues.
• Understanding how attentional focus affects the perception of physical exertion is crucial for optimizing training and performance.

Purpose of the Study:

• To investigate how attention to external environmental cues impacts the perception of physical symptoms and fatigue during exercise.
• To determine if external distractions can attenuate subjective experiences of exertion.

Main Methods:

• Experiment 1: Treadmill exercise with constant physical performance, comparing perception between subjects hearing distracting sounds versus amplified breathing sounds.
• Experiment 2: Cross-country versus lap course jogging of equal length, assessing performance and subjective reports.

Main Results:

• Distracting sounds during treadmill exercise led to lower reported fatigue and fewer symptoms compared to amplified breathing sounds.
• While cross-country jogging was faster, requiring more external attention, subjective fatigue and symptom reports were similar to lap course jogging.

Conclusions:

• Attentional focus dynamically shifts between internal and external information sources during physical activity.
• Directing attention towards external cues can diminish the perception of internal physical symptoms and fatigue, suggesting a mechanism for modulating subjective exercise experience.
