In addition, heart rate variability (HRV) between the same training periods was examined, and whether there was a relationship between changes in hormonal values and HRV. The aim was to determine whether salivary testosterone and cortisol levels could be used to assess the training load of endurance athletes.\n\nTestosterone and cortisol are hormones that have been shown to reflect anabolic/catabolic protein metabolism in the body. Testosterone and cortisol have been studied to respond to physical training both acutely and longer term. Heart rate variability has been found to decrease because of strenuous training and overtraining. The relationship between testosterone/cortisol and HRV are still unclear, even though suggestions of the connection between hypothalamic pituitary (HPA) axis and autonomic nervous system (ANS) have been. This master\u2019s thesis studied the differences in salivary testosterone (awakening: wTes, evening: eTes), cortisol (awakening: wCor, evening: eCor), testosterone/cortisol ratio (awakening: wT/C, evening: eT/C) and nocturnal HRV (RMSSD) on endurance athletes (n = 20) during a preparatory season between low (LT) and high (HT) 4-day period. The study was conducted by daily measurements of salivary hormone levels, heart rate variability and training load conducted during subject\u2019s everyday life. Training load was determined as TRIMP (training stress to training impulse) value based on the time spent in the heart rate zones during exercise (TRIMPhr_zone).\n\nThere were no statistically significant differences in salivary testosterone and cortisol values or HRV between the two training periods (p > 0.05). There were no correlations between changes in hormone levels and heart rate variability. Training load (TRIMPhr_zone) did have a significant difference between studied 4-day periods (p < 0.001). The results did not meet the hypothesis of differing hormonal and heart rate variability values between the LT and HT. Neither was the relationship between HPA axis and ANS confirmed. However, due to the nature of the study and assumed monotonic training, no conclusions can be done.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.abstract", "value": "T\u00e4m\u00e4n pro gradu -tutkielman tarkoituksena oli selvitt\u00e4\u00e4 muuttuvatko syljest\u00e4 mitatut kortisoli- ja testosteroniarvot kevyell\u00e4 ja kovalla nelj\u00e4n p\u00e4iv\u00e4n mittaisella harjoitusjaksolla.
