ABSTRACT: It is generally thought that topical cooling can interfere with blood perfusion and may have positive effects on recovery from a traumatic challenge. This study examined the influence of topical cooling on muscle damage markers and hemodynamic changes during recovery from eccentric exercise. Eleven male subjects (age 20.2±0.3 years) performed 6 sets of elbow extension at 85% maximum voluntary load, and randomly assigned to topical cooling or sham groups during recovery in a randomized crossover fashion. Cold packs were applied to exercised muscle for 15 minutes at 0 h, 3 h, 24 h, 48 h and 72 h after exercise. The exercise significantly elevated circulating creatine kinase-MB isoform (CK-MB) and myoglobin levels. Unexpectedly, greater elevations in circulating CK-MB and myoglobin above the control level were noted in the cooling trial during 48-72 h of the post-exercise recovery period. Subjective fatigue feeling was greater at 72 h following topical cooling compared to controls. Removal of the cold pack also led to a protracted rebound in muscle hemoglobin concentration compared to controls. Measures of IL-8, IL-10, IL-1β, and muscle strength during recovery were not influenced by cooling. A peak shift in IL-12p70 was noted during recovery with topical cooling. These data suggest that topical cooling, a commonly used clinical intervention, appears to not improve but rather delay recovery from eccentric exercise-induced muscle damage.
