Quantitative Analysis of Annual Training Volume and Periodization Patterns in Elite Female Cross-Country Skiers Using GPS Monitoring: A Three-Athlete Case Study

: When benchmarked against world-class female (WCF) standards (800-950 h annually), the overall training volume was approximately 18-30% lower. The relative strength training allocation (22.7%) exceeded typical WCF values (10-15%). These observations should be interpreted cautiously given the small sample size and cross-study comparison design, using published literature-based benchmarks.
