Abstract

Introduction: Saliva collection and analysis is quickly becoming a useful and non-invasive tool for the evaluation of sport biomarkers. The aim of this study is to create a multidisciplinary assessment model, which can help to provide psychological and physiological responses, related to sport performances, social closeness and performance anxiety management in team sports. Materials and methods: We enrolled in our research 26 female volleyball players aged 13 ± 1 years old of three different teams (T1: 12 players; T2: 9 players; T3: 5 players). Saliva collection was carried out before and after the match for every team. Then we analyzed cortisol and progesterone concentrations through Elisa standard kits. Results: The results of the T-test performed on the total results showed a statistically significant relationship (p < 0.05) in cortisol levels pre and post match: in fact, it has been shown a statistical significant decrease (p < 0.001). The analysis performed using just samples post match shows a negative correlation between social closeness, cortisol and progesterone levels, with p < 0.010 for progesterone vs social closeness and p < 0.012 for cortisol vs social closeness, which indicates that increasing of one of the two hormones reduces relationship. About the winner teams and the looser teams, there is a negative correlation between pre match cortisol levels and performance anxiety (p < 0.042).
