We investigated the effect of postmatch cold-water immersion (CWI) on markers of muscle damage, neuromuscular fatigue, and perceptual responses within 72 h after a rugby match. Twenty-two professional male rugby players were randomized into CWI (10 °C/10 min; n = 11) or control (CON: 30 min seated; n = 11) groups. Activity profile from Global Positioning Satellite systems and postmatch rating of perceived exertion were measured to determined match load. Biochemical (tumor necrosis factor alpha (TNF-α), interleukin-6), neuromuscular performance (squat (SJ) and countermovement jumps (CMJ), peak power output (PPO), rate of force development (RFD), stiffness, 10- and 30-m sprint time, and perceptual markers (soreness, perceived recovery) were obtained before and immediately after the match, and then at 30 min, 24 h, 48 h, and 72 h after the match. Magnitude-based inference and Cohen’s effect size (ES) were used to analyze change over time and between groups. Thus, the higher/beneficial, similar/trivial, or lower/harmful differences were evaluated as follows: <1%, almost certainly not; 1% to 5%, very unlikely; 5% to 25%, unlikely; 25% to 75%, possible; 75% to 95%, likely; 95% to 99%, very likely; >99%, almost certainly. Changes were unclear for the match loads, sprint times, and perceptual markers between groups. Higher %ΔSJ at 24 h (very likely (ES = 0.75)) and in %ΔPPO_SJ at 48 h (likely (ES = 0.51)) were observed in CWI than in CON. Values in %ΔRDF_CMJ were higher immediately after (likely (ES = 0.83)), 30 min after (very likely (ES = 0.97)), and 24 h after the match (likely (ES = 0.93)) in CWI than in CON. Furthermore, %Δlog TNF-α were lower in the CWI group than in the CON group immediately after (almost certainly (ES = −0.76)), 24 h after (very likely (ES = −1.09)), and 72 h after the match (likely (ES = −0.51)), and in Δstiffness_SJ at 30 min after (likely (ES = −0.67)) and 48 h after the match (very likely (ES = −0.97)). Also, different within-groups effects throughout postmatch were reported. Implementing postmatch CWI-based strategies improved the recovery of markers of inflammation and fatigue in rugby players, despite no change in markers of speed or perceptual recovery.

We investigated the effects of two common recovery methods; far-infrared emitting ceramic materials (Bioceramic) or cold-water immersion on muscular function and damage after a soccer match. Twenty-five university-level soccer players were randomized into Bioceramic (BIO; n = 8), Cold-water immersion (CWI; n = 9), or Control (CON; n = 8) groups. Heart rate [HR], rating of perceived exertion [RPE], and activity profile through Global Positioning Satellite Systems were measured during the match. Biochemical (thiobarbituric acid reactive species [TBARS], superoxide dismutase [SOD], creatine kinase [CK], lactate dehydrogenase [LDH]), neuromuscular (countermovement [CMJ] and squat jump [SJ], sprints [20-m]), and perceptual markers (delayed-onset muscle soreness [DOMS], and the perceived recovery scale [PRS]) were assessed at pre, post, 24 h, and 48 h post-match. One-way ANOVA was used to compare anthropometric and match performance data. A two-way ANOVA with post-hoc tests compared the timeline of recovery measures. No significant differences existed between groups for anthropometric or match load measures (P > 0.05). Significant post-match increases were observed in SOD, and decreases in TBARS in all groups (p < 0.05), without differences between conditions (p > 0.05). Significant increases in CK, LDH, quadriceps and hamstring DOMS (p < 0.05), as well as decreases in 20-m, SJ, CMJ, and PRS were observed post-match in all groups (p < 0.05), without significant differences between conditions (p > 0.05). Despite the expected post-match muscle damage and impaired performance, neither Bioceramic nor CWI interventions improved post-match recovery.

  Las estrategias que aminoren el dolor, la inflamación y el daño muscular provocados por la actividad física de alta intensidad en atletas son de interés en la recuperación deportiva, por lo que el objetivo del estudio fue conocer el efecto del masaje ZNAR y la inmersión en agua fría a 10° sobre el proceso inflamatorio a través de la interleucina 6 (IL-6), interleucina 10 (IL-10), el factor de necrosis tumoral Alpha (TNF-α), el daño muscular mediante la Creatin Kinasa (CK) y la percepción al dolor muscular a través de la escala visual análoga de dolor (EVA) en jugadores de voleibol. Participaron 19 atletas divididos en un grupo control y un grupo experimental, sometidos a dos protocolos de recuperación (masaje ZNAR e inmersión en agua fría) posterior a un test de inducción a la fatiga. Se cuantifico la IL-6, IL-10, TNF, CK y EVA. Los resultados mostraron cambios significativos (p < .05) en las tomas de recuperación en el comportamiento del proceso inflamatorio, la CK y la percepción al dolor muscular con ambos métodos de recuperación. Conclusión, el Masaje ZNAR favorece a la recuperación de la IL-6 y la IL-10 además de la disminución de la CK y la percepción al dolor muscular.  Abstract: The strategies that reduce pain, inflammation and muscle damage caused by high intensity activity in athletes are of interest in sports recovery, the objective of the study was to know the effect of ZNAR massage and cold water immersion at 10 ° on the inflammatory process through interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor Alpha (TNF-α), muscle damage through Creatine Kinase (CK) and the perception of muscle pain through the visual analoge scale (VAS) in volleyball players. 19 athletes were divided into a control group and an experimental group, submitted to two recovery protocols (ZNAR massage and cold water immersion) after a fatigue induction test. IL-6, IL-10, TNF, CK and EVA were quantified. The results showed significant changes (p < .05) in the recovery shots in the behavior of the inflammatory process, the CK and the perception of muscle pain with both recovery methods. Conclusion, the ZNAR Massage favors the recovery of IL-6 and IL-10 in addition to the decrease in CK and the perception of muscle pain

Purpose: To examine the effects of daily cold- and hot-water recovery on training load (TL) during 5 days of heat-based training. Methods: Eight men completed 5 days of cycle training for 60 minutes (50% peak power output) in 4 different conditions in a block counter-balanced-order design. Three conditions were completed in the heat (35°C) and 1 in a thermoneutral environment (24°C; CON). Each day after cycling, participants completed 20 minutes of seated rest (CON and heat training [HT]) or cold- (14°C; HTCWI) or hot-water (39°C; HTHWI) immersion. Heart rate, rectal temperature, and rating of perceived exertion (RPE) were collected during cycling. Session-RPE was collected 10 minutes after recovery for the determination of session-RPE TL. Data were analyzed using hierarchical regression in a Bayesian framework; Cohen d was calculated, and for session-RPE TL, the probability that d > 0.5 was also computed. Results: There was evidence that session-RPE TL was increased in HTCWI (d = 2.90) and HTHWI (d = 2.38) compared with HT. The probabilities that d > 0.5 were .99 and .96, respectively. The higher session-RPE TL observed in HTCWI coincided with a greater cardiovascular (d = 2.29) and thermoregulatory (d = 2.68) response during cycling than in HT. This result was not observed for HTHWI. Conclusion: These findings suggest that cold-water recovery may negatively affect TL during 5 days of heat-based training, hot-water recovery could increase session-RPE TL, and the session-RPE method can detect environmental temperature-mediated increases in TL in the context of this study.

Clinical Question: Is there evidence to support precooling with cold water immersion prior to endurance cycling and running in hot, humid environments to enhance performance? Clinical Bottom Line: There is moderate evidence suggesting cold water immersion (CWI) as a precooling intervention improves endurance performance in cyclists and runners in a hot, humid environment. All five included studies reported significant improvements in endurance performance regarding time to exhaustion or distance traveled. In all included studies, core temperature was significantly decreased in the CWI group versus the control group during the fifth and twentieth minutes of exercise. No significant differences were reported for the rating of perceived exertion (RPE) between the CWI and control groups.

The purpose of this study was to examine the effect of β-hydroxy-β-methylbutyrate-free acid (HMB-FA) and cold-water immersion (CWI) on circulating concentrations of TNF-α and monocyte TNF-α receptor 1 (TNFR1) expression. Forty resistance-trained men (22.3 ± 2.4 yr) were randomized into four groups [placebo (PL), HMB-FA, CWI, and HMB-FA-CWI] and performed an acute, intense exercise protocol (four sets of up to 10 repetitions of the squat, dead lift, and split squat). Participants also performed four sets of up to 10 repetitions of the squat at 24 and 48 h following the initial exercise bout. Blood was sampled before exercise (PRE), immediately postexercise (IP), and 30 min, 24 h, and 48 h postexercise (30P, 24P, and 48P, respectively). Circulating TNF-α was assayed, and TNFR1 expression on CD14+ monocytes was measured by flow cytometry. The exercise protocol significantly elevated TNF-α in only PL ( P = 0.006) and CWI ( P = 0.045) IP. Mean percent changes show that TNF-α significantly increased from PRE to IP for only PL and CWI groups ( P < 0.05), whereas the percent change of TNF-α for HMB-FA and HMB-FA-CWI was not significant. TNFR1 expression was elevated in PL ( P = 0.023) and CWI ( P = 0.02) at 30P compared with PRE, whereas both HMB-FA-treated groups did not increase significantly. In conclusion, HMB-FA attenuated circulating TNF-α IP and TNFR1 expression during recovery compared with PL and CWI. HMB-FA supplementation may attenuate the initial immune response to intense exercise, which may reduce recovery time following intense exercise.

Inflammatory State

Cold-water immersion (CWI) after exercise is a method used by sportsmen to improve recovery. The aim of the study was to assess the effect of a 3 min CWI on the inflammatory state by measuring levels of interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor α (TNF-α), and transforming growth factor β1 (TGF-β1), and activities of α1-antitrypsin (AAT) and lysosomal enzymes, including arylsulfatase (ASA), acid phosphatase (AcP), and cathepsin D (CTS D), in the blood of healthy recreational athletes. Male volunteers (n = 22, age 25 ± 4.8 yr) performed a 30 min submaximal aerobic exercise, followed by a 20 min rest at room temperature (RT-REST) or a 20 min rest at room temperature with an initial 3 min 8 °C water bath (CWI-REST). Blood samples were taken at baseline, immediately after exercise, and after 20 min of recovery. The IL-6, IL-10, and TNF-α levels and the AAT activity increased significantly immediately after exercise. The IL-6 level was significantly higher after CWI-REST than after RT-REST. No changes in the activities of the lysosomal enzymes were observed. The effect of a 3 min CWI on the level of inflammatory markers during post-exercise recovery was limited. Thus, it might be considered as a widely available method of regeneration for recreational athletes.

High Intensity Exercise

A brief cold water immersion between 2 continuous high-intensity exercise bouts improves the performance of the latter compared with passive recovery in the heat. We investigated if this effect is apparent in normothermic conditions (∼19 °C), employing an intermittent high-intensity exercise designed to reflect the work performed at the high-intensity domain in team sports. Fifteen young active men completed 2 exhaustive cycling protocols (Ex1 and Ex2: 12 min at 85% ventilatory threshold (VT) and then an intermittent exercise alternating 30-s at 40% peak power (Ppeak) and 30 s at 90% Ppeak to exhaustion) separated by 15 min of (i) passive rest, (ii) 5-min cold-water immersion at 8 °C, and (iii) 10-min cold-water immersion at 8 °C. Core temperature, heart rate, rates of perceived exertion, and oxygen uptake kinetics were not different during Ex1 among conditions. Time to failure during the intermittent exercise was significantly (P < 0.05) longer during Ex2 following the 5- and 10-min cold-water immersions (7.2 ± 3.5 min and 7.3 ± 3.3 min, respectively) compared with passive rest (5.8 ± 3.1 min). Core temperature, heart rate, and rates of perceived exertion were significantly (P < 0.05) lower during most periods of Ex2 after both cold-water immersions compared with passive rest. The time constant of phase II oxygen uptake response during the 85% VT bout of Ex2 was not different among the 3 conditions. A postexercise, 5- to 10-min cold-water immersion increases subsequent intermittent high-intensity exercise compared with passive rest in normothermia due, at least in part, to reductions in core temperature, circulatory strain, and effort perception.

Background: Oxidative stress and inflammation increase after eccentric exercise. Cold-water immersion after exercise is common among athletes to accelerate recovery. Therefore, the purpose of this study was to investigate the effect of cold-water immersion after eccentric exercise on the oxidative and inflammatory responses in skeletal muscle. Methods: One hundred male Wistar rats (weight 285.11 ± 41.65) were randomly divided into control, eccentric exercise, eccentric exercise + normal water, and eccentric exercise + cold water groups. Half, 24, 48, 72, and 168 hours after eccentric exercise, EDL muscle was removed in sterile conditions. The eccentric exercise involves 90 minutes of interval running on the treadmill at a speed of 16 m/min and a -16-degree slope. Muscle reactive oxygen species (ROS) and tumor necrosis factor-alpha (TNF-α) levels were measured by DCFDA and immunohistochemical staining. Kolmogorov-Smirnov for normality test and repeated measure ANOVA and Tukey’s post-Hoc tests for compare groups were used with a significance level of P≤0.05. Results: After eccentric exercise, ROS and TNF-α levels significantly (P<0.05) increased in the three experimental groups. The peak of ROS increase in the eccentric exercise, eccentric exercise + normal water, and eccentric exercise + cold water groups were recorded significantly (P<0.001) half, 48, and 72 hours after eccentric exercise, respectively. Also, the peak of TNF-α increase was significantly higher in the eccentric exercise and eccentric exercise + normal water groups were at 48 hours and in the eccentric exercise + cold water groups was at 72 hours after eccentric exercise (P<0.001). Conclusion: Immersion in cold water causes an increase and delays the peak of ROS and TNF-α after eccentric exercise, which is probably related to ischemia-reperfusion injury. Therefore, after unaccustomed, eccentric, and damaging exercise, immersion in cold water is not recommended.
