Temperature Changes in Selected Areas of Body Surface lnduced by Systemic Cryostimulation

Background: The aim of this study was to assess the distribution and dynamics of temperature changes on the surface of selected body parts after systemic cryostimulation. The changes that occurred as a reaction to the 1st, 5th, and 10th session of a series of 10 sessions were also analyzed. Methods: The study group consisted of 24 students (12 women and 12 men, similar to 21 yr of age) from the University School of Physical Education in Krakow. They were treated in a cryogenic chamber at the Rehabilitation Center in Krakow once daily for 10 d. The mean temperature in the chamber was -130 degrees C +/- 10 degrees C and the session duration was 3 min. Thermovisual examination of temperature distribution in the selected parts of the upper and lower extremities was conducted before and immediately after a session on the 1st (Si), 5th (S2), and 10th (S3) day of treatment. All thermograms were digitally recorded using a Flir Therma CAM TM Sc500 camera. Results: On the 5th day of treatment, the examined group demonstrated the smallest mean temperature changes (4.57 degrees C-17.31 degrees C for the anterior part of the upper extremities in men and the posterior part of the lower extremities in women, respectively) before and after cryostimulation. The most significant temperature changes were observed in the group of women (6.80 degrees C-20.08 degrees C for the posterior parts of the upper extremities on S2 and the lower extremities on S3, respectively). Conclusion: There is an important difference in response to cryogenic temperature between men and women in a series.
