Qu, C, Wu, Z, Xu, M, Lorenzo, S, Dong, Y, Wang, Z, Qin, F, and Zhao, J. Cryotherapy on subjective sleep quality, muscle, and inflammatory response in Chinese middle- and long-distance runners after muscle damage. J Strength Cond Res 36(10): 2883–2890, 2022—The purpose of this investigation was to explore the effects of cold-water immersion (CWI), contrast-water therapy (CWT), and whole-body cryotherapy (CRY) on subjective sleep quality, muscle damage markers, and inflammatory markers in middle- and long-distance runners after muscle damage. Twelve male runners from Beijing Sport University completed a muscle damage exercise protocol and were treated with different recovery methods (CWI, CWT, CRY, or control [CON]) immediately after exercise and at 24-, 48-, and 72-h postexercise. The Pittsburgh Sleep Quality Index questionnaire score, lactate dehydrogenase (LDH) activity, myoglobin (Mb) activity, interleukin-6 (IL-6) activity, and soluble intercellular adhesion molecule-1 (sICAM-1) activity were measured at 7 time points (preexercise; immediately postexercise; and at 1-, 24-, 48-, 72-, and 96-h postexercise). Pittsburgh Sleep Quality Index scores indicated that the CRY condition had improved sleep quality compared with the CON and CWI conditions ( p 〈 0.05 ). In terms of LDH activity, the CRY and CWT conditions had improved recovery compared with the CON and CWI conditions ( p 〈 0.05 ). In terms of Mb activity, the CRY condition exhibited improved recovery compared with that of the CON and CWI conditions ( p 〈 0.05 ), and the CWT condition showed better recovery than that of the CON condition ( p 〈 0.05 ). In terms of IL-6 activity, the CRY condition showed improved recovery compared with the CWI condition ( p 〈 0.05 ). Finally, in terms of sICAM-1 activity, the CRY condition had enhanced recovery compared with the other 3 conditions ( p 〈 0.05 ). The results from this study suggest that CRY improves subjective sleep quality and reduces muscle damage and inflammatory responses in middle- and long-distance runners. In addition, CWT reduced muscle damage and inflammatory responses, but its effects on the other parameters were inconclusive.
