dc.description.abstractThe aim of this paper is to describe and analyse the behaviour of heart rate variability (HRV) during constant-load, high-intensity exercise using a time frequency analysis (Wavelet Transform). Eleven elite cyclists took part in the study (age: 18.6 +/- 3.0 years; VO2max: 4.88 +/- 0.61 litres center dot min(-1)). Initially, all subjects performed an incremental cycloergometer test to determine load power in a constant load-test (379.55 +/- 36.02 W; 89.0%). HRV declined dramatically from the start of testing (p < 0.05). The behaviour of power spectral density within the LF band mirrored that of total energy, recording a significant decrease from the outset LF peaks fell rapidly thereafter, remaining stable until the end of the test. HF-VHF fell sharply in the first 20 to 30 seconds. The relative weighting (%) of HF-VHF was inverted with the onset of fatigue, [1.6% at the start, 7.1 (p < 0.05) at the end of the first phase, and 43.1% (p < 0.05) at the end of the test]. HF-VHFpeak displayed three phases: a moderate initial increase, followed by a slight fall, thereafter increasing to the end of the test. The LF/HF-VHF ratio increased at the start, later falling progressively until the end of the first phase and remaining around minimal values until the end of the test.
