Demands of professional female cycling races: Influence race level and race duration (single or multi-day events).

This study is governed by two aims: firstly, expanding the meagre knowledge store regarding the demands set by professional female road cycling and, secondly, ascertaining whether these demands vary in relation to different race-levels and race duration (single- or multi-day events). A total of 1349 female professional road races was analysed and demands (intensity, load and performance) were determined. Races were classified based on race level (i.e. Women's World Tour [WWT], level.1 and level.2 according to the International Cycling Federation) and race duration (single- or multi-day events). Differences were assessed with a multilevel random intercept model whilst the strength of said differences were indicated by Cohen's (0-0.19 trivial; 0.20-0.59 small; 0.60-1.1.9 moderate; 1.20-1.99 large; ≥2.00 very large). In general, no differences for load and intensity were noted for the different race levels. This result contrasts with data obtained from male road cycling. higher 3 and 5 min maximal mean power (MMP) values were noted in the WWT compared to Level.2 races. More substantial differences were found to exist between single- and multi-day races with single-day races presenting to higher load and intensity values. In addition, single-day races presented higher MMPs overall durations (5 s-60 min) although these differences can be rated to . This study contributes to the limited knowledge store describing demands in professional female cycling. The reported data provide valuable insights which may aid practitioners and/or coaches in preparing female professional cyclists for races.Within female professional cycling, some differences were noted in the demands (load, intensity and performances) set by different race levels. However, (in general), these differences were to , which contrasts with male professional cycling.More pronounced differences were noted in the demands set by single- and multi-day races. The load (Work done, eTRIMP and TSS) was to higher in single-day races. Differences in load are primarily caused by a combination of higher duration and higher intensity.No differences in performance measures (i.e MMPs) were noted for different race levels or between single- and multi-day races.
