Populærvitenskapelig sammendrag av avhandlingen/ Summary of the thesis

Many athletes perceive the menstrual cycle (MC) and hormonal contraceptive (HC) use to influence their training, performance, and recovery. However, the current understanding is scarce and inconclusive.

The main aim of this thesis was to explore HC use prevalence and the perceived influence of MC, HC use, and cycle-related symptoms on training, performance, and recovery in female endurance athletes.

With cross-sectional and longitudinal study designs, we found a high prevalence of HC use, with negative MC symptoms being the most common reason for usage. The majority perceived a neutral or solely positive influence of HC usage on training and performance. Mid-luteal phase, pre-bleeding days, and cycle-related symptoms severity appear to negatively influence self-reported measures of recovery in HC and non-HC users. However, it is important to consider other possible stressors, as the MC/HC cycle and related symptoms are just one of many factors that can potentially influence recovery.
