Emerging trends in technological innovations, data analysis and practical applications have facilitated the measurement of cycling power output in the field, leading to improvements in training prescription, performance testing and race analysis. This review aimed to critically reflect on power profiling strategies in association with the power-duration relationship in cycling, to provide an updated view for applied researchers and practitioners. The authors elaborate on measuring power output followed by an outline of the methodological approaches to power profiling.

Article Synopsis
  • * Professional cyclists showed significantly better metrics (power output, ascent velocity, speed) on Cat 1 and Cat 2 climbs compared to U23 cyclists, while U23 cyclists had higher workload and intensity measures.
  • * The results suggest that climbing performance in professional cyclists is influenced by the climb's difficulty and their previous workload and intensity, with these factors being good predictors for Cat 1 and 2 climbs.

Purpose: The aim of this study was to investigate changes in the power profile of U23 professional cyclists during a competitive season based on maximal mean power output (MMP) and derived critical power (CP) and work capacity above CP (W') obtained during training and racing.

Methods: A total of 13 highly trained U23 professional cyclists (age = 21.1 [1.
