To describe the within-season external workloads of professional male road cyclists for optimal training prescription.
Training and racing of four international competitive professional male cyclists (age 24 ± 2 y, body mass 77.6 ± 1.5 kg) were monitored for 12 months prior to the world team time trial championships. Three within-season phases leading up to the team time trial world championships on 20(th) Sept 2015 were defined as phase one (Oct - Jan), phase two (Feb - May) and phase three (June - Sept). Distance and time were compared between training and racing days and over each of the various phases. Time spent within absolute (<100 W, 100 to 300 W, 400 to 500 W, >500W) and relative (0 to 1.9 W·kg(-1), 2.0 to 4.9 W·kg(-1), 5.0 to 7.9 W·kg(-1), >8 W·kg(-1)) power zones were also compared for the whole season and between phases one to three.
Total distance (3859 ± 959 vs 10911 ± 620 km) and time (240.5 ± 37.5 vs 337.5 ± 26 h) was lower (P <0.01) in phase one than phase two, respectively. Total distance decreased (P <0.01) from phase two to phase three (10911 ± 620 vs 8411 ± 1399 km, respectively). Mean absolute (236 ± 12.1 vs 197 ± 3 W) and relative (3.1 ± 0 vs 2.5 ± 0 W·kg(-1)) power output was higher (P <0.05) during racing compared with training, respectively.
Volume and intensity differed between training and racing over each of three distinct within-seasonal phases.
