The accumulated stresses of training and/or competition may temporarily cause impairments in physiological and/or muscular function leading to suboptimal performance. A balance therefore exists between training/competition and recovery to maximize athletic performance. The application of cryotherapy to previously exercised limbs has become a widely used recovery method. Cryotherapy is also typically used in the immediate treatment and management of soft tissueinjuries. The proposed benefits of acute cryotherapy exposure are related to enhanced recovery of performance and reductions in body/local temperatures, microvascular blood flow, oedema, perceived soreness and possibly muscle damage. Furthermore, repeatedcryotherapy bouts have been shown to accentuate endurance training-induced metabolic adaptations but abrogate resistance training-induced metabolic adaptations. The aim of this symposium is to critically examine the vascular, metabolic and performance implications of cryotherapy recovery for sport and exercise performance. Using an integrated approach, this symposium will address the current state of knowledge pertaining to proposed mechanisms of cryotherapy use in sport and exercise settings. Such information has important implications for academics and scientists in a range of fields, including, cardiovascular, metabolism, exercise physiology, as well as exercise science/rehabilitation guidelines for sport and exercise science practitioners working with the public through to the elite athlete.

Within the United States thousands of individuals are treated each year for heat-related injuries, with the most severe cases being among the leading cause of death in athletes. Heat-related injuries are also relatively common in non-athletic settings such as the military and in select occupations. The focus of this symposium is to present novel findings pertaining to environmental and individual risk factors (from the human to the molecule) that increase the susceptibility to a heat-related injury. Dr. Julien Périardw ill first present research on the protective effects of heat acclimation in mitigating heat-related injuries, while also addressing when heat acclimation may not prove beneficial towards this end. Dr. Matthew Cramer will then present research on the challenges that burn survivors face with thermoregulation, resulting in a heightened risk for a heat-related injury. He will also present data on the interaction between biophysical factors and burn injury in affecting a burn survivor’s risk for a heat-relatedinjury and how heat acclimation could mitigate that risk. Dr. Michelle King’s presentation will change the focus to a mouse model of heat stroke, addressing the effects and associated mechanisms of a prior viral illness as a significant risk factor that increases heat stroke severity. Dr. Elizabeth Proctor will conclude the session addressing molecular and cellular signatures of heat stroke, with an objective of identifying diagnostic and prognostic tools to assess heat stroke severity, as well as to identify the mechanism(s) of action by which prior viral illness changes susceptibility to a heat stroke. From this “human to molecular” approach, the audience will obtain important information regarding the impact of novel risk factors on susceptibility to a heat-related injury(Author views not official US Army or DoD policy)

Repetitive heat exposure has an adaptive response to exercise and this has mainly focused on the theme of increasing human performance. However, a ‘one size fits all’ approach may not be appropriate for special populations. In this symposium, there will be discussion on recent work on heat acclimation with elite athletes, Paralympiccompetitors and females. Heat therapy for metabolic disease and heat stress on an aging population will be examined.Elite athletes adhere to regimented training cycles. Therefore, traditional heat acclimation approaches require manipulation to ensure that heat exposures fit properly into the training program for optimal benefits. This presentation will explore how this may be implemented. Paralympic athletes are a population at heightened risk of thermoregulatory strain due to their range of physical impairments. This study aims to provide the first evidence of heat acclimation responses in this group compared to physiologically matched, able-bodied athletes. The effectiveness of short-term heat acclimation (STHA) with a dehydration stimulus have been reported using male participants. The aims of this work were to investigate the effectiveness of STHA (with dehydration) in females controlling for menstrual cycle status versus a matched male cohort.Regular heat exposure as a form of heat therapy may elicit beneficial cardiovascular and metabolic adaptations in humans. This presentation will address the effect of passive heat acclimation on cardiometabolic factors in an overweight and middle-aged population. The potential detrimental health issues of heat stress on an aging population is receiving growing attention worldwide. This work will investigate the genotypic and physiological measures during heat acclimation in the elderly. Furthermore, an alternative heat acclimation approach will be considered.In summary, this symposium will provide the audience with an insight into the use of heat acclimation for special populations from a human performance and health perspective.

Most studies examining physiological responses to cold have been conducted in healthy populations. Less research has focused on individuals who suffer from various diseases. Epidemiological studies show that mortality/morbidity rates are higher in winter compared to summer with increases in death due to ischemic heart disease, stroke, and respiratory disease. Are the cold exposure responses in individuals with clinical disease different from healthy individuals? Does cold exposure pose a greater risk? Should occupational cold exposure guidance be different for people with known health problems? Conversely, data suggest that cold exposure may provide a potential therapeutic effect on disease progression. One question currently being asked is, can chronic coldexposure be used to attenuate metabolic disease? This symposium will present recent findings examining the physiological effects of cold exposure and exercise in individuals with coronary artery disease, respiratory disease, and diabetes. Dr. Tiina Ikäheimo will provide information on the cardiovascular effects of cold exposure among persons having hypertension or coronary artery disease. She will also describe how exercise in the cold and medication modifies those responses. Links between observed pathophysiological responses of cardiovascular diseases and cold related morbidity and mortality will be addressed. Dr. Mariann Sandsund will address respiratory responses to cold exposure, focusing on individuals suffering from exercise-and cold-induced asthma in different occupations as well as in elite athletes. Pharmacological and non-pharmacological treatment and guidance will be discussed related to health and performance. Mr. Michiel Moonen will present metabolic responses to cold exposure, focusing on individuals suffering from diabetes mellitus type 2. The effects of cold acclimation on lipid-and glucose metabolism will be discussed. This symposium will highlight what we do not currently know with regard to acute and chronic cold exposure in individuals with clinical disease and pose questions to be answered in future research efforts.

Environmental heat stress is a societal challenge projected to increase in severity with global warming. High death rates during extreme heat-waves signifies the ultimate outcome for vulnerable groups, but equally important daily day occupational heat stress has important health implications and it affects productivity for billions of workers with derived socio-economic impact. General guidelines and limits for heat stress designed to protect the average worker have been recommended by occupational safety institutes for some time. However, heat stress continues to compromise health and recent reports suggest that this is largely explained by the inability of existing guidelines to consider individual factors that cause extensive variability ina worker’s physiological response to a given level of heat stress. A worker’s physiological response to a given heat stress is modified independently by inter‐individual factors (age, sex, body composition, disease, others) and intra‐individual factors both within (fitness, acclimation and hydration state, others) and beyond their control (work duration, days with exposure, medication use, others). For instance, relative to their younger counterparts, older workers display a reduced capacity to dissipate heat, resulting in a greater heat strain during work in the heat. Physically demanding work in the heat can also cause next‐day effects (fatigue, fluid depletion, others), that augment core temperature increases on the next workday and further increase the risk of heat‐related illness especially in older workers. In conditions that do not exceed the recommended limits, this ‘one size fits all’ approach to heat stress management can lead to reductions in productivity in more heat‐tolerant workers, while compromising safety in less heat tolerant workers who may develop heat‐related illness. In this symposium, we examine the consequences of applying a generalized heat exposure limit for all workers that does not consider the extensive inter‐ and intra‐individualvariation in thermoregulatory function. Further, we discuss future directions to occupational heat stress management that consider this individual variability to create a multi‐level heat protection strategy providing maximum protection to all workers against the detrimental effects of heat spurred by a warming planet. Also, the following general areas will be covered: 1) Defining high risk conditions for heat-vulnerable workers, 2) New strategies for real-time monitoring of heat strain in workers, 3) Scenario-specific and individualized heat management solutions and 4) Protective measures to optimize worker performance and health.

The cold-receptor agonist menthol has been utilised to improve performance by imparting feelings of coolness and freshness to alleviate thermal discomfort. Menthol activates thermoreceptors in a similar manner to thermal changes within an ambient temperature range of 8-28 ̊C. These effects are mediated by peripheral cold-sensitive neurons and trigeminal nerves of the face and oral cavity via activation of TRPM8 channels by either applying, ingesting or swilling menthol solutions. The forcing function exerted by topically applied menthol is probably influenced by a combination of factors, including the percentage of body surface area (BSA) exposed, body region, and dose, but the weighting of each requires clarification, as do factors influencing oral administration. Topically, a greater menthol-mediated forcing function has been shown to alter thermoregulation resulting in heat gain, but the precise mechanisms require clarification. It is unknown whether there is a similar effect when menthol is administered orally, but higher concentrations are reportedly preferred. Consequently, menthol has the potential to improve thermal perception but evoke heat gain responses placing biophysical and behavioural thermoregulation in conflict. Nevertheless, there is a growing body of literature that supports the efficacy of menthol application to improve endurance performance and, more recently, muscular performance.Oral menthol application has been shown to improve time to exhaustion and time trial performance with emerging evidence in power based activities. Independently of the heat storage response, topically applied menthol has also been shown to improve endurance performance and enhance recovery from exercise-induced muscle damage, possibly due to increased motor unit activation. Both methods of application have consistently been shown to ameliorate subjective measures of thermal strain during exercise.Accordingly, the aim of this symposium is to present key literature on the perceptual, thermoregulatory and performance effects of menthol and actively debate the merits of: the medium of application, advised protocols for menthol use during these modalities, the timing of application and the resultant thermoregulatory effects. This symposium will culminate in a consensus statement on menthol use in sporting and occupational settings.

In modern day operations, soldiers are required to carry out a wide range of complex (physical and cognitive) tasks under life-threatening conditions and high-pressure situations. For example they carry high loads, up to 80 kg or more, they wear personal protective clothing, they constantly assess and appraise the situation, process information and make decisions. This symposium focuses on the use of (thermal) modeling to optimize humanperformance (or Soldier performance), through predicting health threats from extreme environment, physical and cognitive challenges and protective ensembles. Thermal modeling often includes modeling (thermoregulation simulation) and manikins (physical simulation). Thermoregulatory models predict human response to heat, cold, physical activity and clothing. In addition there is an increasing interest in the aversive effects of thermal load on cognitive performance. Based on this knowledge, user-friendly tools, such as Decision Aids or Apps, are developed to help Soldiers predict and assess their physiological status and cognitive load, and to determine appropriate strategies to mitigate the multiple stressors they face.This symposium will include seven speakers and will be organized as following: opening presentation 15 minutes, the remainingsix presentations 10 minutes and questions/discussion 15 minutes

“Drowning” remains amongst the top three causes of accidental death around the globe, with over 1,000 people a day losing their lives to drowning. The actual figure for world-wide drowning deaths is probably two or three times higher than this figure; low-and middle-income countries, where most drownings occur, have incomplete recording of drowning events. Furthermore, and sadly topical, drowning as result of flooding, ferryboats accidents and accidents with boats carrying refugees and migrants are not reported in the standard drowning statistics. Although the focus is on mortality, for every death caused by drowning many more suffer life-long morbidity. As such, drowning-related problems rank amongst the largest associated with the environment and, with global warming increasing flooding and water levels, this threat is only set to increase. As an example, in 2016 there were 19,000 drowning deaths in Bangladesh 16,000 of them were children. Although the term “drowning” is in common parlance, immersion and submersion in water evoke a wide range of physiological response that can result in death other than by “the process of experiencing respiratory impairment from submersion or immersion in liquid” (Drowning). For example, recent research has suggested cardiac mechanisms that can result in death on immersion,previous research has identified thermally-related neuromuscular and hypothermic mechanisms. As such, a more accurate term for deaths occurring in water would be “immersion-related deaths” rather than simply “drowning”, and there are many physiological pathways leading to these deaths. Finally, recent considerations have included regarding drowning as a process, with an associated “drowning chain of survival”, that starts with knowledge and prevention in the local community and runs through recognition, protective equipment, rescue and treatment (Fig.1). This model underpins efforts to improve drowning prevention policies and thereby reduce the number of drowning-related deaths.
