Another thermovisual picture was taken in the 3—5 minute after finishing the test [ 5 , 10 ]. Blood pressure measurement was made prior to trial simultaneously with the execution of the thermal images. Thermovisual body surface assessment method was used by many authors to evaluate effects of particular working conditions. The concept of the Hines test is to determine the quantity of the blood pressure increase. Thermovision found a wide application in the analysis of the blood supply change connected with the physical effort of training sportsmen. Thermovisual method uses blood supply and consequently the temperature of the tissues subject to thermal stimulation as well as the disease process [ 14 ]. This may result from the anatomical hand structure and in particular the amount of muscle tissue which appears on the palmar side. A similar thermal stimuli transmission was observed in the present study.
