The purpose of this study was to examine effects of cryotherapy on muscle damage markers and tissue metabolism following eccentric exercise. Thirty adult men were randomly assigned to intensive cooling group (0℃, n=10), a moderate cooling group (25℃, n=10), or control group (no ice, n=10). All subjects performed eccentric exercise of the elbow flexors (10 sets of 6 repetitions, rest for 2 min between each set)) using the non-dominant. After 5 min, the elbow flexor muscles was treated for 20min at controlled temperature of either 0℃ and 25℃, and received non-cryotherapy treatment. Muscle damage markers (range of motion; ROM, circumference; CIR and visual analog scale; VAS) were measured before and after eccentric exercise, before and after cryotherapy, and 24, 48 72 hours after eccentric exercise. Tissue metabolism (surface and core temperatures, blood flow and oxygen dynamic (oxyhemoglobin; H<SUB>b</SUB>O₂, deoxyhemoglobin: Hb, total hemoglobinl tHb) were measured continuity measured before and after exercise, before and after cryotherapy, and 10 min after cryotherapy. ROM in flexor, CIR in median and VAS were significantly improved by cryotherapy (p＜.05). Surface temperature was significantly lower at 0℃(p＜.05) and 25℃(p＜.05) compared to control, and core temperature was significantly lower at 0℃(p＜.05) compared to control. Blood flow was significantly lower at 0℃(p＜.05) after and 10 min after cryotherapy compared to 25℃ and control. H<SUB>b</SUB>O₂ and tH<SUB>b</SUB> were significantly lower at 0℃(p＜.01) and 25℃(p＜.01) after and 10 min after cryotherapy compared to control. However, Hb was significantly higher at 0℃(p＜.01) and 25℃(p＜.01) after and 10 min after cryotherapy compared to control. These results suggest that local tissue cooling inhibits exacerbation of damage, and leads to changes in local circulation, tissue metabolism and oxygen demand. It is thought that cryotherapy also needs to change application temperature if needed.
