The present study was taken up to monitor the training load and the impact of training load to the hormone concentrations such as testosterone, cortisol and T/C (Testosterone/Cortisol) ratio during the three phases of training viz preparatory phase, pre-competitive phase and competitive phase in Indian male swimmers. Blood samples were collected at the completion of each phase and the hormone concentrations were quantified. Our results reveal that the testosterone and T/C ratio significantly decreases whereas cortisol increases in the subsequent periodised cycle and concludes that the hormone concentration changes with the intensity and duration of exercise i.e. when the intensity and duration of exercise is increased, the testosterone level decreases, cortisol level increases and T/C ratio decreases. This study shows a clear picture of performance enhancement with lowest mean cortisol level, high testosterone and T/C ratio level. Hence, monitoring of these hormones is essential to avoid overtraining and to enhance the performance of the swimmers.
