Beyond erythropoietin: What hormonal profiling reveals about the true cost of high‐altitude training

Key Points

• To investigate how hormonal profiling can provide insights into the true costs associated with high-altitude training.
• Performed hormonal profiling during and after high-altitude training periods
• Analyzed the effects on physiological adaptation and performance metrics
• Compared results to typical erythropoietin responses
• Uncovered significant hormonal changes beyond erythropoietin levels during high-altitude training
• Found that hormonal profiling provides a more comprehensive understanding of training costs
• Identified potential negative impacts on athletes' overall physiological health related to hormone fluctuations
