Endocrine and androgenic response to altitude training in professional cyclists Open
This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m ( n = 19) or 3000 m ( n = 12). Serum samples were analysed for stero…

Validity of a machine learning estimation of blood volumes during altitude training Open
Introduction Altitude training is widely used in endurance sports to improve near sea-level performance through physiological adaptations. Overall gains of 1% total hemoglobin mass (Hbmass) for each 100 hours spent at altitude may be expec…

The effects of altitude training on hormonal response in professional cyclists Open
Introduction The Alps offer numerous possibilities for athletes to prepare competitions at altitude training with the aims of further gains for near sea-level performances through physiological adaptations. Hematological adaptations (e.g.,…

The intensity rather than the quantity of prior work determines the subsequent downward shift in the power duration relationship in professional cyclists Open
To determine whether the intensity of prior work is an important contributing factor to the downward shift in the power‐duration relationship. Data were collected from 14 professional cyclists (height 176.3 cm ± 7, body mass 67.3 kg ± 5, C…
