Whole body cryotherapy, cold water immersion, or a placebo following resistance exercise: a case of mind over matter?

par SFCCE | 2019 | Publication Sport

Purpose: The use of cryotherapy as a recovery intervention is prevalent amongst athletes. Performance of high volume, heavy load resistance exercise is known to result in disturbances of muscle function, perceptual responses and blood borne parameters. Therefore, this study investigated the influence of cold water immersion (CWI), whole body cryotherapy (WBC) or a placebo (PL) intervention on markers of recovery following an acute resistance training session.

Methods: 24 resistance trained males were matched into a CWI (10 min at 10 °C), WBC (3- and 4 min at – 85 °C) or PL group before completing a lower body resistance training session. Perceptions of soreness and training stress, markers of muscle function, inflammation and efflux of intracellular proteins were assessed before, and up to 72 h post exercise.

Results: The training session resulted in increased soreness, disturbances of muscle function, and increased inflammation and efflux of intracellular proteins. Although WBC attenuated soreness at 24 h, and positively influenced peak force at 48 h compared to CWI and PL, many of the remaining outcomes were trivial, unclear or favoured the PL condition. With the exception of CRP at 24 h, neither cryotherapy intervention attenuated the inflammatory response compared to PL.

Conclusion: There was some evidence to suggest that WBC is more effective than CWI at attenuating select perceptual and functional responses following resistance training. However, neither cryotherapy intervention was more effective than the placebo treatment at accelerating recovery. The implications of these findings should be carefully considered by individuals employing cryotherapy as a recovery strategy following heavy load resistance training.

Use of Cryotherapy for Managing Chronic Pain: An Evidence-Based Narrative.

par SFCCE | 2020 | Publication Santé

Background: Cryotherapy has been used to reduce chronic pain for many years due in part to its ease of use, affordability, and simplicity. It can be applied either locally (e.g., ice packs) or non-locally (e.g., partial and whole-body cryotherapy) depending on the location of the pain.

Objectives: To determine the overall effectiveness of cryotherapy at reducing chronic pain by characterizing the currently available evidence supporting the use and effects of cryotherapy on chronic pain associated with chronic diseases.

Study design: A narrative review of original research studies assessing the efficacy of cryotherapy in alleviating chronic pain.

Methods: A PubMed database search was performed to find human studies between the years 2000 and 2020 that included the application of cryotherapy in patients with chronic pain associated with chronic diseases. A review of the relevant references was also performed to gather more articles. Data was extracted, summarized into tables, and qualitatively analyzed.

Results: Twenty-five studies (22 randomized controlled trials, one prospective analysis, 1 one-group pretest/posttest study, and one case-control study) were included after the literature search. Both local and non-local cryotherapy applications show promise in reducing chronic pain associated with various chronic diseases including those of rheumatic and degenerative origin. Cryotherapy appears to be a safe therapy in carefully selected patients, with only minimal adverse effects reported in the literature.

Limitations: Meta-analysis was not possible given the many differences between studies. Cross-study data homogenization and comparison between studies proved fairly difficult due to the lack of standardized studies, various uses and practice types of cryotherapy, and lack of control groups in some studies.

Conclusions: Local and non-local cryotherapy can be low-risk and easy treatment options to add in the management of chronic pain in carefully selected patients. However, long-term effects, a standardized approach, and careful study of other chronic pain syndromes should be considered in future research to further support the use of cryotherapy in the management of chronic pain.
