Does squatting need attention?-A dual-task study on cognitive resources in resistance exercise

Area of Science:

• Exercise Science
• Cognitive Neuroscience
• Human Performance

Background:

• Resistance exercise and training enhance cognitive functions.
• Mechanisms linking resistance exercise to cognitive benefits are underexplored.
• Cognitive engagement during resistance exercise execution is not well understood.

Purpose of the Study:

• To quantify cognitive resource allocation during barbell back squats.
• To investigate the cognitive load associated with performing resistance exercises.
• To understand the relationship between cognitive demands and physical exertion during squatting.

Main Methods:

• Young adults performed a cognitive task (serial subtraction) during standing and barbell back squatting.
• Cognitive load was assessed by analyzing the number of total and correct responses.
• Perceived exertion, heart rate, and squat performance were also measured.

Main Results:

• Cognitive task performance (total and correct responses) was significantly lower during squatting compared to standing.
• Accuracy on the cognitive task did not differ between conditions.
• No significant correlation was found between cognitive measures and perceived exertion.

Conclusions:

• Barbell back squats demand greater cognitive resources than standing.
• Increased cognitive load during squatting is not explained by perceived exertion.
• These findings suggest an indirect cognitive training effect from resistance exercise execution.
