This course focuses on the essentials of cold water emergent in sports. Chapter Two will explain how it works, and in particular explains the general principle the main effects and indications. CHAPTER THREE focuses on what the research is telling us in chapter four on how whether emergence should be applied. This chapter will provide guidelines on how to use what are emergent, and which factor needs consideration to increase effectiveness and standardized results. There is no such thing as cold, cold is absence of heat. Human beings cannot feel cold temperatures, the absolute zero temperature, the temperature where molecules will stop moving is at minus 458 degrees Fahrenheit.

Nothing can be cold and is absolute zero on the Kelvin scale. Everything with the temperature above The absolute zero processes heat. Heat is a form of energy produced by the movement, the gentleness of molecules, more gentleness, higher temperature, less gentleness, lower temperature. This gentleness or metabolic rate can be illustrated by infrared thermography, which gives clear visuals on temperature differences. The video illustrates and explains the fundamental difference between cold and heat at how we perceive a difference in temperature. The temperature of regular stuff is basically just a measurement of the jiggle Enos of the atoms and molecules that make that stuff up.

More jiggling, higher temperature, less jiggling, lower temperature. Of course, when something's at a high temperature, it feels hot and when something's at a low temperature, it feels cold, right? Not exactly. If you touch a piece of metal and a book that have been sitting in your fridge, the metal will feel much colder than the book. Derek of veritasium did a great video on this but you really have to try it for yourself to believe it. The metal and the book are honestly at the same temperature as measured by a thermometer, but the metal feels colder.

This isn't just a trick of the mind, though we experienced the metal as colder than the book for a very physical reason. Metal is a conductor and paper is an insulator, so the energy or ugliness of the molecules in our hands is absorbed more quickly by the metal than by the book. Even though the book and the metal are at the same temperature, the metal causes the temperature of our hands to go down faster, and thus we experience the metal as being colder because the temperature of our hands is what we really feel. It's like how technically a mercury thermometer really only measures its own temperature, and you can only indirectly measure temperatures of other things by putting them in thermal contact with it. Similarly, the thermo receptive nerves in our skin can only directly measure the temperature of the skin itself and not have anything else.

So when we touch something, we don't feel its temperature but rather we feel its effect on our skin. That is how much and how quickly it transfers thermal energy that's the juggling of molecules to or from us the capacity to transfer thermal Energy is also why a blast of steam from your stovetop can feel so much hotter than a blast of hot dry air from your oven. Even if the oven has a higher temperature, water vapor transfers more molecular jiggling to your skin than air by itself. In fact, it's tempting to say that hot and cold are fundamentally different concepts from high temperature and low temperature even though we usually use the words interchangeably. Hot really means it gives off a lot of energy while high temperature means it has a lot of energy. And as anyone who's tried fundraising knows, just because somebody has a lot of something doesn't necessarily mean they give a lot of it away.

A blank coolant heater humans, like using an ice pack. immersion into water, or exposure to whole body cryotherapy has a significant impact humans or endothermic homeo terms, we can produce our heat by our metabolism and therefore maintain homeostasis. It is imperative for us to keep our core temperature within a narrow range. typically between 97.2 and 99.8 degrees Fahrenheit, lower core temperatures might result in bodily dysfunctions and the loss of consciousness, while a higher core temperature leads to dysfunction of the circulatory and nervous system, and protein destruction, resulting in depth. For thermal regulatory responses, we consider the central core body temperature in the peripheral shell. This peripheral shell consists of skin, subcutaneous tissue, and muscles.

The human thermal regulatory system comprises of the hypothalamus, the peripheral thermal receptors, the central thermal receptors in the effectors. The thermal regulatory Center is located in the hypothalamus, there is a continuous interaction between the thermo regulatory Center and the central and peripheral feedback neurons to regulate or core temperature within this narrow range. Any difference between the Temperature information from the receptors and the setpoint temperature induces a thermal regulatory response either stimulate heat production or heat dissipation responses that can include non shivering thermogenesis, heat production by brown fat, shivering kidneys faster constriction in facilitation, evaporation and behavioral responses. heat production is derived from cellular metabolism addressed or a site product from external activity. heat loss, defined as heat transfer between body and an external environment or curse to heat convection, heat radiation, heat conduction and heat evaporation always from hot to cold. Heat convection is the heat transfer to or from the body to surrounding moving fluid or air.

Heat conduction is the heat transfer from warmer to cool subjects through direct physical contact. heat radiation is the heat transfer to or from the body theory radiation from higher to lower energy surfaces and heat evaporation is the heat loss due to heat evaporation of sweat from the skin surface. In rest, we continuously lose heat to the environment through radiation, conduction, and convection. exposing the body to call or heat will have its effect on homeostasis and thereby directly impacts our core temperature and peripheral shock. This course is created as a best practice course built on the fundaments determined by David Sackett in 2000. The fundaments focus on the integration of best research evidence with clinical expertise and patient preferences and circumstances.

We are in favor of this approach as cold and heat application is highly integrated in sports practice serving athletes in their performance or rehabilitation. External clinical evidence can inform but cannot replace individual clinical expertise is this expertise that decides whether external evidence applies to the individual athlete at all, and if so, how it should be integrated into the clinical decision. evidence based practice is application of the principles of evidence based medicine to the athlete and patient care. Its goal is to improve the quality and effectiveness of health care. In this section, we discussed the concept of cold and heat. In the next section, we look more specifically into cold water immersion by defining the general principles effect elements and indications
