Abstract

Purpose: To determine how athletes spontaneously use their energetic reserves when the only instruction was to finish in minimal time, and whether experience from repeated performance changes the strategy of recreational athletes. Methods: Recreational road cyclists/speed skaters (N = 9) completed three laboratory time trials of 1500 m on a windload braked cycle. The pattern of energy use was calculated from total work and from the work attributable to aerobic metabolism, which allowed computation of anaerobic energy use. Regional level speed skaters (N = 8) also performed a single 1500-m time trial with the same protocol and measurements. Results: The serial trials were completed in (mean ± SD) 133.8 ± 6.6, 133.9 ± 5.8, 133.8 ± 5.5 s (P > 0.05 among trials); and in 125.7 ± 10.9 s in the skaters (P < 0.05 vs cyclists). The VO
