The aim of this study was to assess the influence of moderate physical exercise on selected blood parameters in regular winter swimmers who suffer from osteoarthritis. The study covered a period of 6 months, from November to April, and was carried out on 17 women and 22 men. The participants were divided into 4 groups: Female CWI – women who only immersed themselves in cold water, Female CWI + PE – women who exercised in addition to water immersion, Male CWI – men who only immersed themselves in cold water, and Male CWI + PE – men, who exercised in addition to water immersion. Venous blood was collected twice, before and after the exercise program. A statistically significant decrease in fibrinogen, plasma viscosity, T ½ , and AMP was observed in the blood of people who did not take part in the physical exercise program while a significant decrease in cortisol levels was observed in the people who participated in the exercise program in addition to cold water immersion. In terms of rheological parameters, a significant increase in the elongation index (EI) of erythrocytes from shear stress 2.19 Pa in all groups was observed. There were no statistically significant changes in AI in all groups. Physical activity has an influence on the blood parameters of elderly winter swimmers suffering from osteoarthritis.

Purpose:To assess the impact of between-training-sessions recovery strategies (passive [PAS], active [ACT], cold-water immersion [CWI], and ingestion of a recovery drink [NUTR]) on maximal cycling performance, perceptions of delayed-onset muscle soreness (DOMS), and fatigue in world-class BMX riders.Methods:Eleven elite BMX athletes, members of the French national team (top country in the 2011 international ranking, 4 medals at the 2012 World Championships, top European country), participated in the study, which involved standardized training periods. Athletes performed 3 maximal-sprint power tests: the first day of the week before the training session and before and after training on the third day of the week (D3). The recovery strategy was randomly assigned to each participant on day 2 immediately after the last training period of the day. Perceptions of DOMS and general fatigue were recorded on D3.Results:After training on D3, the decrease in maximal-sprint power (Pmax) was significantly greater for PAS than with CWI (P = .02) and NUTR (P = .018). Similar results were found with ACT (vs CWI P = .044, and vs NUTR P = .042). Self-reported DOMS and fatigue were significantly greater after PAS than after other strategies.Conclusions:For elite BMX riders, between training days, nutritional and/or CWI recovery strategies appear to be best for reducing muscle fatigue and increasing the capacity to withstand the training schedule.

The Impact

Background: Stress has been considered as one of the causes of decreased reproductive function in women. However, direct evidence of the effect of chronic stress on oocytes depending on estrous cycle phases is limited. Objective: The present study aimed to evaluate the impact of chronic stress on the viability, integrity, and maturation of rat oocytes depending on estrous cycle phases, specifically proestrus, estrus, and diestrus. Methods: For this purpose, adult female rats were stressed daily by cold water immersion (15 °C) for 30 consecutive days. Results: In chronically stressed female rats, irregular estrous cyclicity, increased corticosterone levels, decreased oocyte viability, and an increased percentage of abnormal oocytes were obtained in all the estrous cycle phases, resulting in reduced oocyte maturation during proestrus. Conclusion: Oocyte maturation disturbed by chronic stress is a crucial factor by which chronic stress disrupts female reproduction

Immersion Experience

Experiments have found that choosing between placebo analgesics can reduce pain more than being assigned a placebo analgesic. Because earlier research has shown prior experience moderates choice effects in other contexts, we tested whether prior experience with a pain stimulus moderates this placebo-choice association. Before a cold water pain task, participants were either told that an inert cream would reduce their pain or they were not told this information. Additionally, participants chose between one of two inert creams for the task or they were not given choice. Importantly, we also measured prior experience with cold water immersion. Individuals with prior cold water immersion experience tended to display greater placebo analgesia when given choice, whereas participants without this experience tended to display greater placebo analgesia without choice. Prior stimulus experience appears to moderate the effect of choice on placebo analgesia.

The Mean

This study examined how time of day affects thermoregulation during cold-water immersion (CWI). It was hypothesized that the shivering and vasoconstrictor responses to CWI would differ at 0700 vs. 1500 because of lower initial core temperatures (Tcore) at 0700. Nine men were immersed (20°C, 2 h) at 0700 and 1500 on 2 days. No differences ( P > 0.05) between times were observed for metabolic heat production (M˙, 150 W ⋅ m−2), heat flow (250 W ⋅ m−2), mean skin temperature (T sk, 21°C), and the mean body temperature-change in M˙(ΔM˙) relationship. Rectal temperature (Tre) was higher ( P < 0.05) before (Δ = 0.4°C) and throughout CWI during 1500. The change in Tre was greater ( P < 0.05) at 1500 (−1.4°C) vs. 0700 (−1.2°C), likely because of the higher Tre-T skgradient (0.3°C) at 1500. These data indicate that shivering and vasoconstriction are not affected by time of day. These observations raise the possibility that CWI may increase the risk of hypothermia in the early morning because of a lower initial Tcore.

Objective: The main aim of this study was to determine strategies used toaccelerate recovery of elite rugby players after training and matches, asused by medical support staff of rugby teams in South A frica. A  secondaryaim was to focus on specifics of implementing ice/cold water immersion asrecovery strategy. Design: A  Questionnaire-based cross sectional descriptive survey was used.Setting and Participants: Most (n=58) of the medical support staff ofrugby teams (doctors, physiotherapists, biokineticists and fitness trainers)who attended the inaugural Rugby Medical A ssociation conference linked to the South A frican Sports MedicineA ssociation Conference in Pretoria (14-16th November, 2007) participated in the study. Results: Recovery strategies were utilized mostly after matches. Stretching and ice/cold water immersion were utilized the most (83%). More biokineticists and fitness trainers advocated the usage of stretching than their counter-parts (medical doctors and physiotherapists). Ice/Cold water immersion and A ctive Recovery were the top two ratedstrategies. A  summary of the details around implementation of ice/cold water therapy is shown (mean) as utilized bythe subjects: (i) The time to immersion after matches was 12±9 min; (ii) The total duration of one immersion sessionwas 6±6 min; (iii) 3 immersion sessions per average training week was utilized by subjects; (iv) The average water temperature was 10±3 ºC.; (v) Ice cubes were used most frequently to cool water for immersion sessions, and(vi) plastic drums were mostly used as the container for water. Conclusion: In this survey the representative group of support staff provided insight to which strategies are utilizedin South A frican elite rugby teams to accelerate recovery of players after training and/or matches.

We investigated the underlying molecular mechanisms by which postexercise cold-water immersion (CWI) may alter key markers of mitochondrial biogenesis following both a single session and 6 wk of sprint interval training (SIT). Nineteen men performed a single SIT session, followed by one of two 15-min recovery conditions: cold-water immersion (10°C) or a passive room temperature control (23°C). Sixteen of these participants also completed 6 wk of SIT, each session followed immediately by their designated recovery condition. Four muscle biopsies were obtained in total, three during the single SIT session (preexercise, postrecovery, and 3 h postrecovery) and one 48 h after the last SIT session. After a single SIT session, phosphorylated (p-)AMPK, p-p38 MAPK, p-p53, and peroxisome proliferator-activated receptor-γ coactivator-1α ( PGC-1α) mRNA were all increased ( P < 0.05). Postexercise CWI had no effect on these responses. Consistent with the lack of a response after a single session, regular postexercise CWI had no effect on PGC-1α or p53 protein content. Six weeks of SIT increased peak aerobic power, maximal oxygen consumption, maximal uncoupled respiration (complexes I and II), and 2-km time trial performance ( P < 0.05). However, regular CWI had no effect on changes in these markers, consistent with the lack of response in the markers of mitochondrial biogenesis. Although these observations suggest that CWI is not detrimental to endurance adaptations following 6 wk of SIT, they question whether postexercise CWI is an effective strategy to promote mitochondrial biogenesis and improvements in endurance performance.
