To investigate the influence of carefully defined increase in total training volume on performance, CPK and plasma hormone concentrations in experienced Bobsleighers during 6-weeks of training. Six subjects (four Bobsleighers and two control groups) participated in this study. During 6-weeks of training, Bobsleighers plasma testosterone, cortisol, serum SHBG, CPK and control test were monitored and results obtained in each case. The following results were obtained to design training program for Bobsleighers. 1) CRS was good index for control of training intensity, volume and frequency. 2) Serum CPK was changed to react to training volume rather than training intensity. 3) Secretion of plasma testosterone, cortisol and serum free testosterone varied with amount of physiological and/or psychological stress. 4) Practical experience with the plasma testosterone/SHBG ratio revealed that the tests are very useful not only to monitor training program but also to monitor the volume of training. 5) During the Reduced training periods, repeated and selected plasma hormone analyses seem to be needed to evaluate more thoroughly the actual trainability status of an individual athlete. The practical results obtained with these tests suggest that training monitored in this way can lead to better training program and results.
