Abstract:
This is a randomized crossover study design. We examined the acute effects of prolonged social media use (SMU) vs. computerized Modified Stroop Task (MST) on electroencephalogram (EEG) spectral power and physical performance in taekwondo (TKD) athletes. Fifteen athletes underwent cognitive manipulations (SMU, MST, documentary [DOC]), followed by mental tiredness checks (Visual Analogue Scale [VAS]), EEG measurements, an intermittent TKD task, and psychobiological variables (heart rate [HR], rating perceived exertion [RPE]). Only MST significantly increased the VAS (p < 0.05). Theta power decreased in the parietal cortex after cognitive manipulations across conditions (p < 0.001). MST presented a time effect for theta, alpha 1, and alpha 2 in parietal cortex during the task at 15 min (ps < 0.004), diminishing over time. Physical performance declined throughout rounds (p < 0.001), more under MST vs. DOC (p = 0.03). RPE increased (p < 0.001); no significant difference in HR was found (ps > 0.07). High cognitive demand tasks may impair the performance of TKD athletes.
