Purpose: To determine the effect of 2 cold-water-immersion (CWI) temperatures (15°C and 8°C) on repeat handgrip performance to failure. Methods: A total of 32 participants completed 3 intermittent trials to failure on a climbing-specific handgrip dynamometer on 3 laboratory visits. For each visit, a different recovery strategy was employed: passive (PAS) recovery, CWI at 8°C (CW8), or CWI at 15°C (CW15). The force time integral (FTI: time of contraction multiplied by the force of contraction) was determined to assess handgrip performance. Results: There was no significant difference between recovery strategies at the end of trial 1. In response to the PAS recovery strategy, there were 10% and 22% decreases in FTI in the second and third trials, respectively. The PAS recovery-strategy FTI values were lower than both CWI strategies for trials 2 and 3 (P < .05). FTI increased in the second trial (↑32% and ↑38%; P < .05) for both immersion strategies (CW8 and CW15, respectively) compared with trial 1. During the third trial, FTI was significantly higher for CW15 than CW8 (↑27% and ↓4% with respect to baseline trial; P < .05). Conclusions: The results suggest that CWI has potential performance advantages over PAS recovery for rock climbing. The data show that in events where multiple recoveries are required, 15°C CWI may be more beneficial for climbers than 8°C CWI. Future research should focus on the optimization of protocols for sport performance.

AbstractThis investigation sought to determine whether post-exercise cold water immersion and low glycogen availability, separately and in combination, would preferentially activate either the Exon 1a or Exon 1b Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) promoter. Through a reanalysis of sample design, we identified that the systemic cold-induced augmentation of total PGC-1α gene expression observed previously (Allan et al. in J Appl Physiol 123(2):451–459, 2017) was largely a result of increased expression from the alternative promoter (Exon 1b), rather than canonical promoter (Exon 1a). Low glycogen availability in combination with local cooling of the muscle (Allan et al. in Physiol Rep 7(11):e14082, 2019) demonstrated that PGC-1α alternative promoter (Exon 1b) expression continued to rise at 3 h post-exercise in all conditions; whilst, expression from the canonical promoter (Exon 1a) decreased between the same time points (post-exercise–3 h post-exercise). Importantly, this increase in PGC-1α Exon 1b expression was reduced compared to the response of low glycogen or cold water immersion alone, suggesting that the combination of prior low glycogen and CWI post-exercise impaired the response in gene expression versus these conditions individually. Data herein emphasise the influence of post-exercise cooling and low glycogen availability on Exon-specific control of total PGC-1 α gene expression and highlight the need for future research to assess Exon-specific regulation of PGC-1α.

High Intensity Interval

High-intensity interval training (HIIT) induces vascular adaptations that might be attenuated by postexercise cold-water immersion (CWI). Circulating angiogenic cells (CAC) participate in the vascular adaptations and circulating endothelial cells (CEC) indicate endothelial damage. CAC and CEC are involved in vascular adaptation. Therefore, the aim of the study was to investigate postexercise CWI during HIIT on CAC and CEC and on muscle angiogenesis-related molecules. Seventeen male subjects performed 13 HIIT sessions followed by 15 min of passive recovery (n = 9) or CWI at 10 °C (n = 8). HIIT comprised cycling (8–12 bouts, 90%–110% peak power). The first and the thirteenth sessions were similar (8 bouts at 90% of peak power). Venous blood was drawn before exercise (baseline) and after the recovery strategy (postrecovery) in the first (pretraining) and in the thirteenth (post-training) sessions. For CAC and CEC identification lymphocyte surface markers (CD133, CD34, and VEGFR2) were used. Vastus lateralis muscle biopsies were performed pre- and post-training for protein (p-eNOSser1177) and gene (VEGF and HIF-1) expression analysis related to angiogenesis. CAC was not affected by HIIT or postexercise CWI. Postexercise CWI increased acute and baseline CEC number. Angiogenic protein and genes were not differently modulated by post-CWI. HIIT followed by either recovery strategy did not alter CAC number. Postexercise CWI increased a marker of endothelial damage both acutely and chronically, suggesting that this postexercise recovery strategy might cause endothelial damage. Novelty HIIT followed by CWI did not alter CAC. HIIT followed by CWI increased CEC. Postexercise CWI might cause endothelial damage.

Summary Study aim: To investigate the effect of cold water immersion (CWI) on muscle damage indexes after simulated soccer activity in young soccer players. Material and methods: Eighteen professional male soccer players were randomly divided into two groups: CWI (n = 10, age 19.3 ± 0.5, body mass index 22.2 ± 1.3) and control (n = 8, age 19.4 ± 0.8, body mass index 21.7 ± 1.5). Both groups performed a simulated 90-minute soccer-specific aerobic field test (SAFT90). Then, the CWI group subjects immersed themselves for 10 minutes in 8°C water, while the control group subjects sat passively for the same time period. Blood samples were taken before, immediately after, 10 minutes, 24 hours and 48 hours after the training session in a fasted state. Blood lactate, creatine kinase (CK) and lactate dehydrogenase (LDH) enzyme levels were measured. Results: Lactate, CK and LDH levels increased significantly after training (p < 0.001). There were significant interactions between groups and subsequent measurements for CK (p = 0.0012) and LDH (p = 0.0471). There was no significant difference in lactate level between the two groups at any aforementioned time. Conclusion: It seems that CWI after simulated 90-minute soccer training can reduce the values of muscle damage indexes in soccer players.

Expired air volumes were measured from a random population of adult male and female human volunteers before and during short-term immersion in either cold (13.53 ± 0.13 °C) or warm (33.18 ± 0.11 °C) water. A statistically significant difference was found in the pulmonary ventilation over the first 4 min of immersion between males and females when immersed in cold water. The swim suits worn could not account for the differences observed. No statistically significant difference in pulmonary ventilation was found between males and females during warm water immersion. A numerically smaller group of volunteers was preheated in a sauna before immersion in cold or warm water and this resulted in an attenuated ventilatory response. In this instance there is no statistically significant difference in ventilation between males and females. Also, in another small group of volunteers, surface and deep skin temperatures were continuously measured before and during immersion in cold water. The rates of change of deep skin temperature between males and females were found to be similar.

The aim of this study was to investigate the effect of cold-water immersion (CWI) on lipid peroxides and antioxidant enzymes in adult Taekwondo athletes after a match. A cross-sectional study was performed. After a Taekwondo match, the control group remained seated passively, while the treatment group immersed their legs below the knee joint in cold water at 10 °C. Blood samples were taken at pre-match, post-match, post-treatment, and post-rest, and changes in malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GPx) concentrations were analyzed. The results showed that there was a significant difference in MDA between the two groups, and while the CWI group had 19% lower SOD concentration compared to the control group, and the difference was not significant. However, in case of interaction for GPx concentration (p < 0.001), a statistically significant difference was found between the two groups (p < 0.05). In conclusion, CWI after a Taekwondo match elevates the concentration of antioxidant enzymes.

Many athletes are using specific techniques to minimize fatigue and accelerate recovery processes. Cold water immersion (CWI) is one of the most popular interventions used by athletes to potentially return to their pre-fatigue performance level. the purpose of this study was to investigate the effects of CWI on anaerobic performance, balance and muscle activation of female karateka after a simulated match. 15 young female karateka (age: 18.7±1.7 years, body mass: 55.5±6.3 kg, height:165±5.1 cm) with at least three years' experience in karate kumite fighting were included in the study. After three round 3-minute competition, participants were grouped into a CWI group (20 min at 12±1°C) and a control group (CTL). Anaerobic power (30 s Wingate test), and dynamic balance (Star-Excursion test) were measured before the competition and 24 h after intervention. Surface electromyography (EMG) was sampled from quadriceps femoris muscles. Peak normalized muscle activation levels and force were identified during maximal isometric test. A significant decrease in the anaerobic performance after the competition was observed for both groups (p<0.05). CWI were effective in enhancing the anaerobic performance after competition compared with the CTL. Dynamic balance decreased for two groups, although CWI resulted in the smallest reduction in balance. There was a significant difference in peak and mean RMS values of the EMG in Rectus Femoris but not Vastus muscles after the CWI intervention when compared to CTL (p<0.05). CWI improve recovery related to dynamic balance and anaerobic performance of karate kumite fighter. It can be concluded that CWI appears to promote muscle activation and reduce fatigue that is related to better performance in 24 hours post intervention.

Shivering Thermogenesis

The present study investigated whether nitrous oxide (N2O) attenuates shivering thermogenesis during cold water immersion in a dose-dependent manner. Seven male subjects were immersed to the neck for 60 min in 20 degrees C water on five separate occasions while breathing either air (AIR) or a normoxic mixture of 10, 15, 20, or 25% N2O balanced with N2. All N2O concentrations investigated caused a significant (P < 0.02) reduction in shivering thermogenesis compared with AIR. Despite similar heat flux from the skin, the relative changes in esophageal temperature from resting preimmersion levels were significantly greater (P < 0.05) during the N2O trials compared with AIR, with no significant difference among the N2O conditions. A dose-dependent trend in the perception of thermal comfort was observed for the N2O conditions. It is concluded that shivering thermogenesis, and thus thermal balance, is affected to the same degree for the range of inspired N2O concentrations investigated, with no discernable dose-dependent effect.

Abstract Introduction: Cryotherapy is a technique that involves the application of low temperatures in the treatment of acute injuries, with ice being the simplest and oldest therapeutic modality for this. Objective: To compare two different cold water immersion protocols (standard and intermittent) on the ankle region of healthy volunteers, we analyzed changes in static postural stability, threshold, and pain tolerance immediately after application. Method: This is a quasi-experimental study, controlled clinical trial, and non-probabilistic sampling. The total sample consisted of 40 male patients aged 18 to 30 years. Two different cold water immersion protocols (standard and intermittent) were compared for their effects on pain threshold, tolerance, and static postural stability. Results: There were no significant differences between the groups with regards to the stabilometric variables after the application of both protocols (p > 0.05). There was a significant difference in the threshold and tolerance of the two groups after the application of cold water immersion (p < 0.05); however, there were no significant differences between the groups (p > 0.05). Conclusion: Both cold water immersion protocols proved to be safe for static postural balance, without showing deficits in stabilometric variables. Regarding the analgesic effect, both were effective and significantly increased the threshold and tolerance of ankle pain after cryoimmersion, without any differences between groups. Thus, intermittent 10-minute cold water immersion is sufficient to generate the same analgesic effect as the standard 20-minute pattern, with no change in static postural stability.
