Partial Body Cryostimulation (PBC) consists of exposing minimally dressed participants to very cold air, in a specially designed cabin (cryo-cabin), for a short period of time. In recent years, cryo-cabins have been launched with a coverage to limit thermo-dispersion, however a validation study is lacking. The aim of this study was to compare thermal responses after a PBC protocol in an open cryo-cabin or into a cryo-cabin closed at the top with a polyurethane-made lid. Eighteen young male adults completed the two 150 s PBC sessions in a cross-over fashion. Temperature of the inner cabin and thermal responses were measured prior and 1, 5, 10, 20 min after completing each PBC session. When covered, cryo-cabins maintained a lower temperature in the front with respect to the back. There was a significant interaction regarding coveragetimeposition with a main effect of coverage. Body surfaces were significantly colder under covered condition compared to open PBC. Subjects perceived a greater thermal discomfort during a covered PBC rather than during an open condition. For the first time, the use of a coverage placed on the top of the cabin was demonstrated to maintain lower temperatures of the inner environment and the users' skin with respect to a standard PBC. This evidence indicates that practitioners and clinicians making use of PBC can successfully and safely cover cryo-cabins with an insulating lid so to improve the effectiveness of their treatments.
部分身体冷冻疗法（PBC）包括让穿着最少的参与者在专门设计的舱室内（冷冻舱）暴露在极冷的空气中，时间很短。近年来，已经推出了带有覆盖物的冷冻舱，以限制热扩散，但缺乏验证研究。本研究的目的是比较在开放冷冻舱或顶部用聚氨酯制成的盖子封闭的冷冻舱中进行 PBC 方案后的热反应。18 名年轻男性以交叉方式完成了两次 150 秒的 PBC 疗程。在每次 PBC 疗程前后测量了内舱的温度和热反应。当覆盖物覆盖时，冷冻舱的前部比后部保持更低的温度。在覆盖物时间位置方面存在显著的相互作用，具有覆盖物的主要影响。与开放 PBC 相比，覆盖条件下的身体表面明显更冷。与开放 PBC 相比，在覆盖的 PBC 过程中，参与者感觉到更大的热不适。这是首次证明，在舱室顶部放置覆盖物可以保持内部环境和使用者皮肤的较低温度，从而提高 PBC 治疗的效果。这一证据表明，使用 PBC 的从业者和临床医生可以成功且安全地用隔热盖覆盖冷冻舱，以提高其治疗效果。
