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.

Cold water immersion (CWI) and active recovery (ACT) are frequently used as postexercise recovery strategies. However, the physiological effects of CWI and ACT after resistance exercise are not well characterized. We examined the effects of CWI and ACT on cardiac output (Q̇), muscle oxygenation (SmO2), blood volume (tHb), muscle temperature (Tmuscle), and isometric strength after resistance exercise. On separate days, 10 men performed resistance exercise, followed by 10 min CWI at 10°C or 10 min ACT (low-intensity cycling). Q̇ (7.9 ± 2.7 l) and Tmuscle (2.2 ± 0.8°C) increased, whereas SmO2 (−21.5 ± 8.8%) and tHb (−10.1 ± 7.7 μM) decreased after exercise ( P < 0.05). During CWI, Q̇ (−1.1 ± 0.7 l) and Tmuscle (−6.6 ± 5.3°C) decreased, while tHb (121 ± 77 μM) increased ( P < 0.05). In the hour after CWI, Q̇ and Tmuscle remained low, while tHb also decreased ( P < 0.05). By contrast, during ACT, Q̇ (3.9 ± 2.3 l), Tmuscle (2.2 ± 0.5°C), SmO2 (17.1 ± 5.7%), and tHb (91 ± 66 μM) all increased ( P < 0.05). In the hour after ACT, Tmuscle, and tHb remained high ( P < 0.05). Peak isometric strength during 10-s maximum voluntary contractions (MVCs) did not change significantly after CWI, whereas it decreased after ACT (−30 to −45 Nm; P < 0.05). Muscle deoxygenation time during MVCs increased after ACT ( P < 0.05), but not after CWI. Muscle reoxygenation time after MVCs tended to increase after CWI ( P = 0.052). These findings suggest first that hemodynamics and muscle temperature after resistance exercise are dependent on ambient temperature and metabolic demands with skeletal muscle, and second, that recovery of strength after resistance exercise is independent of changes in hemodynamics and muscle temperature.

Context:An athlete’s ability to recover quickly is important when there is limited time between training and competition. As such, recovery strategies are commonly used to expedite the recovery process.Purpose:To determine the effectiveness of both cold-water immersion (CWI) and contrast water therapy (CWT) compared with control on short-term recovery (<4 h) after a single full-body resistance-training session.Methods:Thirteen men (age 26 ± 5 y, weight 79 ± 7 kg, height 177 ± 5 cm) were assessed for perceptual (fatigue and soreness) and performance measures (maximal voluntary isometric contraction [MVC] of the knee extensors, weighted and unweighted countermovement jumps) before and immediately after the training session. Subjects then completed 1 of three 14-min recovery strategies (CWI, CWT, or passive sitting [CON]), with the perceptual and performance measures reassessed immediately, 2 h, and 4 h postrecovery.Results:Peak torque during MVC and jump performance were significantly decreased (P < .05) after the resistance-training session and remained depressed for at least 4 h postrecovery in all conditions. Neither CWI nor CWT had any effect on perceptual or performance measures over the 4-h recovery period.Conclusions:CWI and CWT did not improve short-term (<4-h) recovery after a conventional resistance-training session.

Dapat disimpulkan Cold Water Immersion suhu 5°C selama 15 menit mempercepat Proses Recovery, mengurangi Inflamasi Otot dan menurunkan Stress, sedangkan Statis Stretching meningkatkan Fleksibilitas setelah Latihan Berbeban Intensitas Sub Maksimal. AbstractStrength is one of the main components of bio-motor affecting the development of other physical components. Strength training improves strength and neuromuscular coordination, muscle hypertrophy, contrary causes physical stressor, muscle inflammation, produce muscular disease, increases lactate levels, interferes body metabolism, thus decreases performance. Appropriate recovery methods can prevent over-training, musculoskeletal injuries, stress levels. The study examines the effect of cold water immersion 5°C (CWI5°C) on blood lactate, muscle soreness, flexibility, and stress level after high-intensity resistance training. The study design was pre- and posttest using a cross-sectional approach with a control group. It gave selected 15 samples treated with CWI5°C for 15 minutes directly after high-intensity resistance training, while control samples with static stretching for 15 minutes. The prerequisite test uses Shapiro-Wilk, while the bivariate analysis uses paired sample T-test and independent sample T-test. The prerequisite test uses Shapiro-Wilk, while the bivariate analysis uses paired sample T-test and independent sample T-test. The results showed there were significant differences between the two groups (p=0.001). The CWI-5 C method recover lactate levels faster (p = 0.001), reduces muscle pain (p=0.003), decrease stress (p=0.002), while SS increase muscle flexibility (p=0.001). We can conclude that 15°C cold water immersion for 15 minutes accelerates recovery, reduce muscle inflammation and stress level, while static stretching increases flexibility after high-intensity resistance training.

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.

Recovery Strategies

Cycling events often include multiple races a day or racing over consecutive days. Congested competition schedules and increased training load have led to the implementation of recovery strategies; with the goal of alleviating post-exercise fatigue and enhancing subsequent performance. This review aims to review the efficacy of recovery strategies used following different cycling events. Compression garments have been shown to improve subsequent 30s – 30min mean cycling power and 5-min max cycling power, while cold water immersion may improve 5-15s sprint cycling power output, 1-15min time trial (TT) total work performed and mean power output in hot and humid conditions. Cold water immersion was also more beneficial than active recovery at improving total work performed. Contrast water therapy could increase 15s – 15min TT work performed and sprint mean and peak power output. Similarly, active recovery has been shown to improve power measures and time to completion. Conversely, hot water immersion appears to be detrimental to sprint power output and TT power output over consecutive days. Thermoneutral water immersion appears beneficial for improving average cycling speed and time to completion during a 20-km TT, where humidification therapy and sports massage are beneficial at improving sprint and middle duration time trial performance. A combination of recovery strategies appear more beneficial than stand-alone strategies and various combinations should be explored further.

Valid Estimate

Context:  No evidence-based recommendation exists regarding how far clinicians should insert a rectal thermistor to obtain the most valid estimate of core temperature. Knowing the validity of temperatures at different rectal depths has implications for exertional heat-stroke (EHS) management. Objective:  To determine whether rectal temperature (Trec) taken at 4 cm, 10 cm, or 15 cm from the anal sphincter provides the most valid estimate of core temperature (as determined by esophageal temperature [Teso]) during similar stressors an athlete with EHS may experience. Design:  Cross-sectional study. Setting:  Laboratory. Patients or Other Participants:  Seventeen individuals (14 men, 3 women: age = 23 ± 2 years, mass = 79.7 ± 12.4 kg, height = 177.8 ± 9.8 cm, body fat = 9.4% ± 4.1%, body surface area = 1.97 ± 0.19 m2). Intervention(s):  Rectal temperatures taken at 4 cm, 10 cm, and 15 cm from the anal sphincter were compared with Teso during a 10-minute rest period; exercise until the participant's Teso reached 39.5°C; cold-water immersion (∼10°C) until all temperatures were ≤38°C; and a 30-minute postimmersion recovery period. The Teso and Trec were compared every minute during rest and recovery. Because exercise and cooling times varied, we compared temperatures at 10% intervals of total exercise and cooling durations for these periods. Main Outcome Measure(s):  The Teso and Trec were used to calculate bias (ie, the difference in temperatures between sites). Results:  Rectal depth affected bias (F2,24 = 6.8, P = .008). Bias at 4 cm (0.85°C ± 0.78°C) was higher than at 15 cm (0.65°C ± 0.68°C, P &lt; .05) but not higher than at 10 cm (0.75°C ± 0.76°C, P &gt; .05). Bias varied over time (F2,34 = 79.5, P &lt; .001). Bias during rest (0.42°C ± 0.27°C), exercise (0.23°C ± 0.53°C), and recovery (0.65°C ± 0.35°C) was less than during cooling (1.72°C ± 0.65°C, P &lt; .05). Bias during exercise was less than during postimmersion recovery (0.65°C ± 0.35°C, P &lt; .05). Conclusions:  When EHS is suspected, clinicians should insert the flexible rectal thermistor to 15 cm (6 in) because it is the most valid depth. The low level of bias during exercise suggests Trec is valid for diagnosing hyperthermia. Rectal temperature is a better indicator of pelvic organ temperature during cold-water immersion than is Teso.
