运动后冷冻治疗通常是短时间的干预措施。本研究考察了相变材料（PCM）长期冷却对偏心运动后力量损失和疼痛的影响。8名成人进行了120次双侧偏心股四头肌收缩（90% MVC）。随后立即将冷冻PCM包（15°C）置于股四头肌上，将室温PCM包置于对侧股四头肌上。连续记录皮肤温度（应用PCM 6 h）。在运动前、运动后24、48、72和96小时分别评估等长股四头肌力量和酸痛。5个月后重复该方案，将室温PCM应用于双腿。有三种处理：腿用15°C PCM包处理（直接冷却），腿用15°C PCM包对侧的室温PCM包处理（系统冷却），腿5个月后用室温PCM包处理（对照组）。与系统冷却和对照组相比，直接冷却组皮肤温度降低9°C - 10°C （P < 0.01）。与系统冷却和对照组相比，直接冷却组的力量损失和疼痛更少（P < 0.05）（强度分别为101%，94%,93%；疼痛分别为1.0,2.3,2.7）。6小时的PCM冷却耐受性良好，减少了损伤性运动后的力量损失和疼痛。
ABSTRACT Post-exercise cryotherapy treatments are typically short duration interventions. This study examined the efficacy of prolonged cooling using phase change material (PCM) on strength loss and pain after eccentric exercise. Eight adults performed 120 bilateral eccentric quadriceps contractions (90% MVC). Immediately afterwards, frozen PCM packs (15°C) were placed over the quadriceps, with room temperature PCM packs on the contralateral quadriceps. Skin temperature was recorded continually (6 h PCM application). Isometric quadriceps strength and soreness were assessed before, 24, 48, 72 and 96 h post-exercise. The protocol was repeated 5 months later, with room temperature PCM applied to both legs. There were three treatments: legs treated with 15°C PCM packs (direct cooling), legs treated with room temperature PCM packs contralateral to the 15°C PCM packs (systemic cooling), and legs tested 5 months later both treated with room temperature PCM packs (control). Skin temperature was 9°C–10°C lower with direct cooling versus systemic cooling and control (P < 0.01). Strength loss and soreness were less (P < 0.05) with direct cooling versus systemic cooling and control (strength 101%, 94%, 93%, respectively; pain 1.0, 2.3, 2.7, respectively). Six hours of PCM cooling was well tolerated and reduced strength loss and pain after damaging exercise.
