The standard deviations of change scores for total and fat-free soft tissue mass (FFST) from Random scans (2-3%) were approximately double those observed in the Best (1-2%), owing to extra random errors associated with Random scans at baseline. There was little difference in change scores for fat mass. The effect of cold water immersion therapy on baseline-taper changes in FFST was possibly harmful (-0.7%; 90% confidence limits ±1.2%) with Best scans but unclear with Random scans (0.9%; ±2.0%). Both protocols gave similar possibly harmful effects of cold water immersion therapy on changes in fat mass (6.9%; ±13.5% and 5.5%; ±14.3%, respectively). ...
Weve all seen videos of athletes giving post-game interviews from the discomfort of locker room ice baths. Does this recovery strategy really work, and can those benefits be enjoyed by typical gym-goers in addition to competitive athletes? And how do timing and duration factor in? This latest ACE-sponsored research answers these questions and more.
Abstract: The autonomic nervous system reflexively controls many physiological systems, including the cardiovascular and ventilatory systems. Water immersion causes fluid shifts within the body that increase central blood volume and intravascular fluid volume. These increases are thought to cause changes in autonomic activity, however it is not known if sympathetic nerve activity is reduced during water immersion. Because the autonomic nervous system controls the cardiovascular and ventilatory systems, it is imperative to understand changes in autonomic activity during water immersion in order to develop countermeasures to protect Navy and recreational divers from potentially adverse physiological responses to the environmental conditions that they are exposed to. This project will examine how changes in both water temperature and breathing gases influence autonomic activity during head out water immersion ...
Immersion of the human body in water has several physiological effects, some of these are directly due to immersion, and are caused by the external hydrostatic pressure of the water providing support against the internal hydrostatic pressure of the blood. Other effects are due to water temperature and heat transfer. Immersion in water affects the circulation, renal system and fluid balance, breathing, and thermal balance. Immersion in cold water is causatively associated with drowning and hypothermia. Plasma fluid losses due to immersion diuresis occur within a short period of immersion. Head-out immersion causes a blood shift from the limbs and into the thorax. The fluid shift is largely from the extravascular tissues and the increased atrial volume results in a compensatory diuresis. Plasma volume, stroke volume, and cardiac output remain higher than normal during immersion. The increased respiratory and cardiac workload causes increased blood flow to the cardiac and respiratory muscles. ...
There are proven acute regenerative benefits of both cold water immersion and cold application after exercise... cool? Not so cool, no. Two recent studies demonstrate: In the long run both will impair your gains.
A reduction in body temperature is considered to be the primary mechanism by which cold water immersion (CWI) enhances short-term (h) recovery and improves exercise capacity in the heat. However, improvement in exercise performance may be optimised at a given cooling magnitude. Water temperature and immersion duration influence the magnitude of cooling in the core body, muscle and skin. Given the role of blood flow in convective heat flux, substrate delivery and metabolic waste clearance, it is important to understand the influence of different water temperatures on compartmental distribution of limb blood flow during CWI. Therefore, the purpose of this study was to compare blood flow changes in the common femoral artery, vastus lateralis muscle, and thigh skin induced by 5 min of post-exercise water immersion at 8°C, 14°C, 35°C or passive rest. In a randomised manner, nine recreationally active men performed exhaustive cycling in a climate control chamber (32.8 ± 0.4°C and 32 ± 5%rh), followed by
The effects of cold acclimation (CA) on the cardiorespiratory responses to cold air and water stress tests (CST) were studied in seven males before and after a CA program of daily 90 min cold water (18 C) immersions repeated five times a week for five consecutive weeks. The CST consisted of a 90 min resting exposure to cold air or water during which rectal temperature (T sub re), oxygen consumption (VO2), carbon dioxide production (VCO2), minute ventilation (V sub E), heart rate (HR), cardiac output (Q) and blood pressure (BP) were periodically measured. In cold air following CA, the VO2 at 10 minutes was lower post than pre CA, however, no differences were found in cold water. The (V sub E) increased during CST as a function of VCO2. The CA did not affect the (V sub E)-VCO2 relationship or the pattern of breathing during CST in cold air or water. The CA had no effect on Q or (a-V) O2 difference, which both increased during the first 45 min of CST, then remained stable. BP increased significantly during

1. Four Macaca fascicularis monkeys were bilaterally sympathectomized by removing the thoracic sympathetic chain from the middle cervical ganglion to the T-6 sympathetic ganglion. This was done chronically, allowing adequate recovery time. While under light pentobarbital anaesthesia, the animals were then subjected to blood volume expansions with isotonic, isooncotic dextran or to head-out immersions. Seven immersions and seven volume expansions were carried out.. 2. With immersion, there were significant increases in blood pressure, central venous pressure, urine flow, sodium excretion, potassium excretion, glomerular filtration rate, percentage of filtered sodium excreted and free water clearance. Although blood pressure and central venous pressure initially increased during the first immersion period, heart rate continued to increase with the immersion, while blood pressure and central venous pressure remained constant. Volume expansion caused an increase in central venous pressure, urine ...

Dont ever think that boating activities wont expose you to the risk of hypothermia. Wear rain gear when it rains. A windbreaker over a fleece jacket is very effective to protect against the wind. Hypothermia can occur on what begins as a warm, sunny day. In remote areas, carry matches and go ashore if you need to build a fire. Also carry an extra jacket, hat, and blankets. Remember that, as a responsible operator, you should tell your passengers what to bring along for the outing.. ...

Heat acclimation by post-exercise hot water immersion (HWI) on six consecutive days reduces thermal strain and improves exercise performance during heat stress. However, the retention of adaptations by this method remains unknown. Typically, adaptations to short-term, exercise-heat-acclimation (max in the heat (33°C, 40% RH) before (PRE) and 24 h after (POST) the HWI intervention (n = 13) and then at 1 week (WK 1) and 2 weeks (WK 2) after the HWI intervention (n = 9). Heat acclimation involved a 40-min treadmill run (65% max) on six consecutive days in temperate conditions (20°C), followed by ≤40 min HWI (40°C). Post-exercise HWI induced heat acclimation adaptations that were retained for at least 2 weeks, evidenced by reductions from PRE to WK 2 in: resting rectal core temperature (Tre, −0.36 ± 0.25°C), Tre at sweating onset (−0.26 ± 0.24°C), and end-exercise Tre (−0.36 ± 0.37°C). Furthermore, mean skin temperature (Tsk) (−0.77 ± 0.70°C), heart rate (−14 ± 10 beats⋅min-1),
Im happy and beyond tired," said Grace Mah, who spearheaded the Mandarin immersion push.. Many of the concerns raised about Palo Altos program were also brought up when Cupertinos pioneer program began a decade ago. One Cupertino parent at the time questioned the value of language immersion. "Cupertino caters too much to the Chinese," she told a neighborhood newspaper after the Mandarin immersion was proposed to the school board. "Mandarin should be taught at home.". Seed money for the Cupertino program was a $175,000 grant from the U.S. Department of Education. But in the beginning, some parents and residents objected to use of district funds and staff time for the immersion program - just as opponents have objected in Palo Alto.. Parents of Cupertino immersion students countered with a solution of their own: They said they would raise supplemental funds for the program.. "For any successful program, a huge amount of parent involvement was needed to keep it sustained," said Jerry Wang, a ...
The marked reduction in breath-hold time (i.e., volitional apnea) with cold water immersion and submersion has obvious implication for escape from within vessels, helicopters, and vehicles that have accidentally sunk, as a well as immersion in rough water. The volume of the inspiratory gasp and the minute volumes resulting from the uncontrollable hyperventilation (minute ventilation ,100 liters) that occurs on immersion in cold water should be compared with the lethal volume for sea water aspiration, 22 ml/kg or ∼1.5 liters for a 70-kg human (52). The observation of the high incidence of cardiac arrhythmias following the release of breath hold has implications for snorkeling and breath-hold diving, as well as for survival following near drowning.. In many countries, water birth has become commonplace. For example in the United Kingdom, the UK Central Council for Nursing has stated that assistance at water birth is part of a midwifes duties and not "special treatment" (13, 78). Each midwife ...
In a study of 6 men aged 29 to 48 we studied the effect of water body immersion during air or pure oxygen, or oxygen - 4 % CO2 gas mixture breathing upon pulmonary volumes and respiratory biomechanics (using bodyplethysmography), the extent of lung hydration (two-frequency impedansometry), and pulmonary metabolic function (by determination of the concentration of biologically active substances in the condensate of the exhaled air). We found an additive nature of immersion/hyperoxic effects upon the respiratory and metabolic pulmonary functions manifested in an acceleration and growth of a deficit in pulmonary vital capacity, a bronchoconstriction effect, increase of a lung hydration, and decrease of serotonin catabolism. Contrary to our expectation, we did non find any potentiation of oxygen induced toxic effects upon the lungs during immersion/hyperoxia/hypercapnia exposures ...
Any victim pulled from cold water should be treated for hypothermia - this is the very dangerous and important stage of survival which is a result of cold water immersion. At this point, you should seek trained medical treatment immediately. Symptoms of hypothermia may include intense shivering, loss of coordination, mental confusion, cold and blue (cyanotic) skin, weak pulse, uncontrolled breathing, irregular heartbeat, and enlarged pupils. Once shivering stops, core body temperature begins to drop critically. Try to prevent body cooling and get the victim to a medical facility immediately.. ...

In this research, a simple and fast method was employed to synthesize CuO nanoleaves/silica gel nanocomposites (CuO/SGn), which is a cost effective antimicrobial material. CuSO4.5H2O is the only raw material used in CuO/SGn production through the molten salt method. The structure and morphology of the nanocomposites were characterized by DRS, XRD, and SEM. The copper size in CuO/SG was found to be dependent on the immersion time in molten salt. SEM images revealed smaller-sized particle leaves, from a sample obtained after longer immersion time.The antimicrobial activity of CuO/SGn was investigated against Escherichia coli. The produced CuO/SGn showed inhibitory effect against E. coli. However, the growth-inhibitory effect depends on the copper content and size. Lower loading of CuO nanoparticles in 10 min immersion time resulted in less antibacterial activity (73.33%) and sample obtained from longer immersion time demonstrated higher antibacterial activity (up to 99.96%). The maximum amount of released
This review evaluated the effects of precooling via cold water immersion (CWI) and ingestion of ice slurry/slushy or crushed ice (ICE) on endurance performance measures (e.g. time-to-exhaustion and time trials) and psychophysiological parameters (core [Tcore] and skin [Tskin] temperatures, whole body sweat [WBS] response, heart rate [HR], thermal sensation [TS], and perceived exertion [RPE]). Twenty-two studies were included in the meta-analysis based on the following criteria: (i) cooling was performed before exercise with ICE or CWI; (ii) exercise longer than 6 min was performed in ambient temperature ≥26°C; and (iii) crossover study design with a non-cooling passive control condition ...
This study investigated the effect of regular postexercise cold water immersion (CWI) on muscle aerobic adaptations to endurance training. Eight males performed 3 sessions/wk of endurance training for 4 wk. Following each session, subjects immersed one leg in a cold water bath (10°C; COLD) for 15 min, while the contralateral leg served as a control (CON). Muscle biopsies were obtained from vastus lateralis of both CON and COLD legs prior to training and 48 h following the last training session. Samples were analyzed for signaling kinases: p38 MAPK and AMPK, peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), enzyme activities indicative of mitochondrial biogenesis, and protein subunits representative of respiratory chain complexes I-V ...
This review includes 12 trials (3243 women): eight related to just the first stage of labour: one to early versus late immersion in the first stage of labour; two to the first and second stages; and another to the second stage only. We identified no trials evaluating different baths/pools, or the management of third stage of labour.. Results for the first stage of labour showed there was a significant reduction in the epidural/spinal/paracervical analgesia/anaesthesia rate amongst women allocated to water immersion compared to controls (478/1254 versus 529/1245; risk ratio (RR) 0.90; 95% confidence interval (CI) 0.82 to 0.99, six trials). There was also a reduction in duration of the first stage of labour (mean difference -32.4 minutes; 95% CI -58.7 to -6.13). There was no difference in assisted vaginal deliveries (RR 0.86; 95% CI 0.71 to 1.05, seven trials), caesarean sections (RR 1.21; 95% CI 0.87 to 1.68, eight trials), use of oxytocin infusion (RR 0.64; 95%CI 0.32 to 1.28,five trials), ...
A method for cleaning dirty objects using cleaning fluid and rinsing fluid and an apparatus using the method. The method has consecutive steps of spraying the surface of a dirty object with high pressure spray of cleaning fluid, immersing the dirty object in an immersion chamber containing cleaning fluid, spraying additional cleaning fluid at high pressure into the immersion chamber at a location downstream from the initial location where the dirty object is immersed to turbulate cleaning fluid therein to scrub the surface of the dirty object, removing the dirty object from the immersion chamber, and spraying the surface of the dirty object with a high pressure spray of rinsing fluid.

In September 1996, Montgomery County [Maryland] started what it promoted as the first Mandarin Chinese immersion program for elementary students in the country. The program at Potomac Elementary School became a national model, and acclaim and fame followed. Today, the original class of first-graders are seniors preparing for college. Many continued to study Chinese in middle and high school, but most dropped out in recent years - a handful as late as this fall - citing confusion in the curriculum and difficulties with the instructor. Now, just three of the first 22 students continue to study Chinese at the clusters high school….. Critics say there is a lack of resources and appropriate materials, poor coordination among grade levels and inadequate teacher development.

"Its a modern day alternative to cold water immersion, ice baths or ice packs" says owner Peter Watson. "It involves exposing the skin to extreme cold, dry (below -140 deg) for one to three minutes.. Liquid Nitrogen is safely used to achieve the sub zero temperatures, which deliver numerous health benefits. Exposing the skin to these extreme temperatures briefly, triggers the release of anti-inflammatory molecules, endorphins, increased oxygen in the blood and a release of toxins" Peter says..
