Özet:

The aim of the present study was to investigate the changes on HRV right after a Wingate Anaerobic Test (WAnT) in physically active men. The subjects performed a single 30-sec. WAnT. Their alactacid and lactacid relative power values were recorded. They participated a five-minute HRV test right before and after the WAnT. The time- and frequency-domain parameters of HRV were recorded and compared. According to the results all HRV parameters including the time- and frequency-domain parameters were significantly changed after the anaerobic loading (for HR, SDNN, SDSD, RMSSD, TP, LF, LF:HF ratio, and VLF p<0.01; and for HF p<0.05). It could be concluded that the time- and frequency-domain parameters of HRV are impaired after a supramaximal anaerobic loading. The future studies can examine the recovery process by measuring the HRV during for a long period of time after the loading.
