Psychological profiles of gender and personality traces of Brazilian professional athletes of futsal, and their influence on physiological parameters

The present study aimed to identify the psychological profiles of professional futsal players in terms of the gender schema and to evaluate the physiological parameters (speed, acceleration, strength, and power) and fatigue index of these athletes according to their gender profiles and relative to their positions on the court. The Masculine Inventory of the Self-concept Gender Schemas was used to classify the sample into typological groups, and the Running Anaerobic Sprint Test was used to measure the physiological parameters (speed, acceleration, strength, and power) and the fatigue index. The study sample was composed of 64 male professional futsal players who competed in the National Indoor Soccer league in 2013; the subjects had an average weight of 76.00±6.7 kg. Among the athletes studied, 23 (35.9%) were classified as heteroschematic female, 22 (34.4%) as heteroschematic male, and 19 (29.7%) as isoschematic. Regarding their positions on the court, eleven were goalkeepers (17.2%), 13 (20.3%) were defenders, 28 (43.8%) were midfielders, and 12 (18.8%) were attackers. The players had similar weights even when belonging to different typological groups and having different positions in the court. However, it is worth noting that male heteroschematic players had a greater mean weight (77.11±5.93 kg) and that the goalkeeper was, on average, the heaviest player (79.36±8.14 kg). The results of the physiological parameter analysis relative to typological group showed that, on average, high-level soccer players presented similar performance profiles in different rounds, as statistically significant differences were not found in any of the studied physiological variables (weight, distance, speed, acceleration, strength, power, and fatigue index). Although the results of this research did not reveal statistically significant differences between the groups in terms of the assessed variables, we observed that some results related to personality traits associated with both the male and female components could help to clarify and establish relationships with some strategic aspects inherent to futsal.
