ABSTRACT
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 (nâ¯=â¯11) were tested twice using a within-participant, balanced cross-over design that consisted of 5â¯×â¯5â¯min of high-intensity running (HIR) followed by either 3â¯min of WBC at -110⯰C or a passive control condition (CON). Before the HIR and after 60â¯min of recovery a ramp-test was completed. At seven time points up to 24â¯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 râ¯=â¯-0.61, pâ¯=â¯0.04; CON râ¯=â¯-0.64, pâ¯=â¯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.Palavras-chave
