Cryotherapy has gained popularity among athletes across many sports. The main goals of cryotherapy, and specifically whole-body cryotherapy, are for injury prevention and counteracting negative inflammatory symptoms following athletic performance in hopes of improving recovery.

As soluble intercellular adhesion molecule-1 (sICAM-1) was recently hypothesized to be a key player in the mechanisms involved in exercise-induced muscular damage (EIMD), we investigated its circulating concentration changes in athletes before and after EIMD with and without the use of whole-body cryostimulation (WBC; 3 min at -110 °C) at the exercise end and repeated once a day during 4 days. We previously characterized plasma specimens from 11 endurance athletes who performed twice (randomized crossover design) strenuous running leading to EIMD, followed by passive recovery or WBC. Muscle soreness and inflammatory response were observed in both cases but the use of WBC induced a significant reduction in these responses (PlosOne 2011; 6:e22748). We now found that sICAM-1 concentration slightly increased in both circumstances and remained elevated for 24 h (p < 0.01). However, no significant WBC effect was observed concerning sICAM-1 changes indicating that this compound is not a major player both in EIMD and WBC physiological impacts.

Purpose: This study examined the acute effects of a single session of Whole-body Cryotherapy (WBC) following severe intermittent running exercise on biomarkers of inflammation, muscle damage and stress.
Methods: Endurance-trained males (n = 11) were tested twice using a within-participant, balanced cross-over design that consisted of 5 × 5 min of high-intensity running (HIR) followed by either 3 min of WBC at -110 °C or a passive control condition (CON). Before the HIR and after 60 min of recovery a ramp-test was completed. At seven time points up to 24 hrs post exercise venous blood samples were analyzed for serum levels of interleukin 6 (IL-6), interleukin 10 (IL-10), c-reactive protein (CRP), soluble intercellular adhesion molecule-1 (sICAM-1), myoglobin, cortisol, and testosterone.
Results: HIR induced significant increases in all biomarkers except sICAM-1 in both recovery conditions, respectively. Compared to the CON condition WBC did not attenuate exercise- induced changes in IL-6, IL-10, sICAM-1, myoglobin, cortisol, testosterone or their ratio. Increased levels of cortisol following exercise were negatively correlated with subsequent running performance in both conditions (WBC: r = -0.61, p = 0.04; CON: r = -0.64, p = 0.04).
Conclusion: The results of this study suggest that the postulated physiological mechanisms by which WBC is proposed to improve recovery, i.e. reductions in inflammation and muscle damage, may not be accurate.

Background: The purpose of this study was to estimate the effect of whole-body cryostimulation (WBC) and subsequent kinesiotherapy on inflammatory endothelium and oxidative stress parameters in healthy subjects.
Methods: The effects of ten WBC procedures lasting 3 min per day and followed by a 60-min session of kinesiotherapy on oxidative stress and inflammatory endothelium parameters in healthy subjects (WBC group n = 32) were analyzed. The WBC group was compared to a kinesiotherapy only (KT; n = 16) group. The following parameters were estimated one day before the start, and one day after the completion of the studies: oxidative stress parameters (the total antioxidant capacity of plasma (FRAP), paraoxonase-1 activity (PON-1), and total oxidative status (TOS)) and inflammatory endothelium parameters (myeloperoxidase activity (MPO), serum amyloid A (SAA), and sCD40L levels).
Results: A significant decrease of PON-1 and MPO activities and TOS, SAA, and sCD40L levels as well as a significant FRAP increase were observed in the WBC group after the treatment. In addition, the SAA levels and PON-1 activity decreased significantly after the treatment in both groups, but the observed decrease of these parameters in the WBC group was higher in comparison to the KT group.
Conclusion: WBC procedures have a beneficial impact on inflammatory endothelium and oxidative stress parameters in healthy subjects, therefore they may be used as a wellness method.
