Heart rate during moderate exercise and cognitive function among adolescents: An experimental study

Area of Science:

• Neuroscience
• Exercise Physiology
• Cognitive Psychology

Background:

• Limited research exists on cognitive function during physical exertion.
• Understanding immediate cognitive impacts during exercise is crucial for productivity and therapy.

Purpose of the Study:

• To investigate the relationship between heart rate and cognitive performance (attention) in adolescents.
• To explore the influence of body mass index (BMI) and sleep quality on attention during physical activity.

Main Methods:

• 32 adolescents (12-18 years) completed the D2 attention test.
• Assessments were conducted at rest and at target heart rates of 100, 120, and 140 bpm.
• Analysis included correlations with BMI and sleep quality.

Main Results:

• A significant positive correlation was found between heart rate and attention (r = 0.39, P < .005).
• Attention showed a significant negative correlation with BMI (r = -0.37, P = .039).
• Sleep quality positively correlated with attention (r = 0.66, P = .014).

Conclusions:

• Moderate physical activity, indicated by increased heart rate, can enhance attention in adolescents.
• Findings suggest potential applications in educational, therapeutic, and occupational settings.
• Further research is recommended to explore broader cognitive domains and populations.
