The key to success in high performance sports is the optimization in planning and timing of training stimuli and rest periods to avoid overloading and overtraining. It is the aim of this article to pass on comprehensive experience with the Orthostatic Test (OT) and the resulting changes for individual training and trainings control to interested scientists, coaches and athletes. The OT is a special position-change test with heart rate monitoring in RR mode for 3 minutes while lying and 3 minutes while standing. The OT was performed with the heart rate monitor V800 (Polar, Finland). Test evaluations are carried out with the "PolarFlow" program. Vagal heart rate variability parameters RMSSD are analyzed during supine and standing position, heart rate (HR) during supine and standing position, and HF peak immediately after active standing up. Monitored tests and training protocols of a female elite long-distance runner from August 2014 to February 2017, selected training sessions from general preparation, training camps and competition season were analyzed. Results: Following a very high volume aerobic endurance training (HVT) RMSSD parameter in supine position rise significantly above personal reference values while RMSSD in standing position is significantly lower than normal. In some cases, HR in supine position is not higher than HR during standing position. After several days of intensive training with a high proportion of the training load at and above the individual anaerobic threshold, resulting HR curve in OT is completely different. HR values are significantly increased immediately after standing up and while standing compared to personal reference values and RMSSD is lower in standing position. Furthermore it is shown that training at high altitude and in competition preparation (tapering phase) changes the OT. Conclusion: Daily OT measurements are helpful during high volume training (HVT) or high intense training (HIT) phases, in changing climate conditions and during training at high altitude, in order to control functional or non-functional overreaching (FOR, NFOR) and to avoid overtraining.
