Thermal characterization in professional volleyball athletes
Keywords:volleyball, skin temperature, thermoregulation, thermography
This study aimed to establish the skin temperature thermal profile of upper- and lower-body for high-performance volleyball players and evaluate the thermal symmetry of contralateral body regions. Thermograms were obtained from 14 male volleyball players (age: 19.4± 2.6 years, body mass: 82.4± 13.6 kg, height: 190.3± 10.4 cm, body fat: 11.9%), members of an elite Brazilian team. Average and maximum skin temperatures were measured in the forearms, arms, shoulders, thighs, legs, and trunk region. The independent T-test was used to compare the temperature between bilateral body regions. We observed thermal similarity between the right and left sides in all analyzed body regions (p> 0.05). In all body regions, mean bilateral thermal differences were considered clinically acceptable (≤ 0.49°C), with effect sizes ranging between insignificant and small. In conclusion, high-performance volleyball players show contralateral thermal symmetry in their upper and lower limbs, suggesting a normal thermographic assessment indicative of injuries. The trunk’s skin temperature values are higher when compared to lower and upper limbs.
