Abstract

Introduction: The beneficial effects of exercise on cognitive performance are frequently reported in the literature, while its effects on neural parameters as the individual alpha peak frequency (iAPF), that is positively related to cognitive performance remain largely unknown. Therefore the aim of the present study was to evaluate the effects of different physical exercise protocols on the iAPF. Methods: Electroen- cephalographic activity was recorded in 12 healthy males before, directly after and 10 minutes after an incremental cycling test (ramp test) until subjective exhaustion and a 30 minutes lasting cycling protocol at 50% of the maximum power output (MPO), respectively. Electrical power values were calculated in the occipital region using fast fourier transformation. The iAPF was determined as the frequency indicat- ing the highest power between 7 and 13 Hz. Results: After the incremental test the iAPF was significantly increased and remained elevat- ed 10 minutes after exercise. In the 50% MPO protocol the IAPF was consistent throughout the measurements. Conclusion: The different effects of the two exercise protocols on the iAPF might be best explained by their discrepancy in intensity probably indicating the necessity for high intensity exercise to increase the iAPF.
