During each cryotherapy session, subjects of the CRYO group received 3 cold air (–30°C) applications of 4 minutes duration each, generated by a Cryo 6 skin cooling system (Zimmer Medizin Systems, Neu-Ulm, Germany). Cold pulsed air was applied to the dominant arm at the maximal available air flow power (intensity = 9) over a 5-cm wide × 13-cm high area beginning 2 cm above the distal tendon. The scanning consisted of vertical and horizontal motions, with a 5-cm distance kept between the tube nozzle and the skin. One minute without cryotherapy occurred between each application to avoid any burns due to extreme cold. Participants stayed in a resting position for 5 minutes after the last application. Skin temperature was monitored during the first 2 cryotherapy treatments with an infrared thermometer29 (Kimo, Montpon, France) to evaluate the decrease in skin temperature. During the cooling, the average skin temperature was 9.6°C ± 0.8°C with a minimum value of 3.4°C ± 0.8°C (Figure 2). This 23.7°C decrease meets the literature recommendations of a 5°C to 15°C skin temperature during 20 minutes to obtain a sufficient effect of cooling on muscle function.3,22 The CONT participants passively recovered from exercise.
