Pre-cooling is used by many athletes for the purpose of reducing body temperature prior to exercise and, consequently, decreasing heat stress and improving performance. Although there are a considerable number of studies showing beneficial effects of pre-cooling, definite conclusions on the effectiveness of pre-cooling on performance cannot yet be drawn. Moreover, detailed analyses of the specific conditions under which pre-cooling may be most promising are, so far, missing. Therefore, we conducted a literature search and located 27 peer-reviewed randomized controlled trials, which addressed the effects of pre-cooling on performance...

This quasiexperimental two-group pilot study tested an intervention aimed at educating older adults in rural communities about the appropriate use of nondrug treatments for pain. Earlier data reveal that older adults use significantly less nonpharmacologic modalities than their younger counterparts, and that pain self-treatment is prevalent in rural areas. Individuals aged ≥60 years who experienced pain in the preceding 2 weeks were recruited from rural Midwestern communities through the use of flyers and information sessions at hospitals, churches, and community organizations...

The purpose of this study was to investigate the effects of acupuncture (dry needling) and heating (application of hot pack) treatments on the blood volume and oxygen saturation of the human Achilles tendon in vivo. Nine healthy males participated in this study. During the treatments (acupuncture and heating; both 10 min) and recovery period (30 min), the blood volume and oxygen saturation of the Achilles tendon were measured using red laser lights. During needle insertion, the blood volume and oxygen saturation of the tendon increased significantly from the pre-treatment level and these values remained high throughout the 30-min recovery period...

Electrophysical agents (EPAs) are a core part of physiotherapy practice and entry level education. With the increase in the number of EPAs over time, their availability and use in contemporary physiotherapy practice is an important consideration when determining entry level curricula. Thus, the aim of the study was to ascertain the current availability and usage of EPAs in Australian physiotherapy practice. A purpose-designed questionnaire was mailed to all registered physiotherapists in Australia. A response rate of 27% was obtained (n=3,538)...

OBJECTIVE: Research over the last decade has supported the use of cold intravenous (IV) fluid as a method for initiating therapeutic hypothermia in post-cardiac arrest resuscitation. However, prehospital care programs employing this treatment have encountered various difficulties. Barriers to prehospital induced hypothermia (IH) protocols include the lack of effective or economically reasonable methods to maintain cold saline in the field. Validation of a simple method could allow agencies to equip numerous rigs with cold saline...

We used three techniques of precooling to test the hypothesis that heat strain would be alleviated, muscle temperature (Tmu) would be reduced, and as a result there would be delayed decrements in peak power output (PPO) during exercise in hot, humid conditions. Twelve male team-sport players completed four cycling intermittent sprint protocols (CISP). Each CISP consisted of twenty 2-min periods, each including 10 s of passive rest, 5 s of maximal sprint against a resistance of 7.5% body mass, and 105 s of active recovery...

A three-dimensional model is developed in this study to examine the transient and steady state temperature distribution in the brain during selective brain cooling (SBC) and subsequent rewarming. Selective brain cooling is induced through either wearing a cooling helmet or packing the head with ice. The ischemic region of the brain is simulated through reducing the blood perfusion rate to 20% of its normal value. The geometric and thermal properties and physiological characteristics for each layer, as well as the arterial blood temperature, are used as the input to the Pennes bioheat equation...

Extracorporeal circuits such as cardiopulmonary bypass (CPB) and renal dialysis machines cause active and/or passive loss of body heat. Attempts to quantify this heat loss are generally based on the Fick principle which requires knowledge of the specific heat capacity (SHC) of blood. As changes in packed cell volume are common, we investigated the effect of these changes on the SHC of blood over a range of packed cell volumes (PCV) from whole blood at 43.1% (3594 J kg-1 degrees C-1) to pure Hartmann's solution (4153 J kg-1 degrees C-1)...

OBJECTIVE: Hypothermia can have a negative effect on the metabolic and hemostatic functions of patients with traumatic injuries. Multiple methods of rewarming are currently used in the prehospital arena, but little objective evidence for their effectiveness in this setting exists. The purpose of this study was to assess the relative effectiveness of traditional prehospital measures in maintaining thermostasis in trauma patients. METHODS: Participating helicopter and ground ambulance ALS units were prospectively randomized to provide either routine care only (passive or no warming) or routine care (passive warming) in conjunction with active warming (either reflective blankets, hot pack rewarming, or warmed IV fluids)...

Neurons within the central nervous system, including those within the ventromedial hypothalamic (VMH) nucleus, alter their neuronal activity in response to scrotal thermal stimulation. This study set out to establish if the thermoresponsiveness of VMH neurons becomes modified to repeated trials of scrotal thermal stimulation. VMH extracellular activity was recorded with a glass micropipette filled with 0.5 M sodium acetate in urethane-anaesthetized male Sprague-Dawley rats following 20 min scrotal heating (scrotal packs, 2 x 2 cm, filled with 40 degrees C hot water) and scrotal cooling (scrotal packs filled with ice)...

The feasibility of combining local heat treatment with whole-body hypothermia in an effort to improve therapeutic gain was assessed. Superficial, nonperfused phantom tumors were fashioned in eight anesthetized mongrel dogs by transplantation of the spleen from the abdomen to a subcutaneous site on the hindlimb. After pretreatment of the animal with the vasodilator hydralazine (0.5 mg/kg, IV) to enhance normal tissue perfusion, the spleen implant was heated with a 2450-MHz microwave diathermy apparatus, first with the animal's core body temperature in the normal range (39 degrees C) and then after the animal had been packed in ice to reduce core temperature to 30 degrees C...
