• PURPOSE: To determine and classify spectral and fractal properties of S, SF and SL fluctuations and interrelationships with half-marathon running performance. METHODS: High-resolution (1 Hz) data on S (m/s), SF (Hz) and SL (m) were assessed during half-marathon (21,098 m) competition using a miniaturized accelerometric device in 21 male experienced runners (38 + or - 11 yrs, BMI: 23 + or - 2 kg*m super(-2)). Performance times, coefficient of variation (CV), spectral powers (TP) and peaks (PP), fractal scaling exponent (beta) and fractal dimension (FD) of S, SF and SL were computed. RESULTS: Fractal and spectral variability measures were independent of performance. The semi-partial explanation of S variation was 84 + or - 6 % for SL and 16 + or - 6 % for SF. PP (r = 0.56) and beta (r = 0.91) were interrelated for S and SL.
