The human body unlike other animals, is designed to function more effectively at a temperature of 98.6 degrees Fahrenheit. Anything above or below, will cause the body to lose some amount of performance. As the body attempts to regulate its core temperature, in an effort to reestablish balance, some unnecessary functions will suffer. for example, if the body temperature is too low a person my become fatigued more easily and suffer a loss in energy. There are many issues to consider when exercising in cold weather conditions. One of the primary considerations is the cold weather knowledge of the person in charge of the group being exposed. Another, is the current health of the individuals being exposed; such as does anyone has asthma or a previous cold weather injury. When exercising in cold weather it is vital that a complete analysis is done to include not just the current health issue of participates. The analysis should also include, the length of exposure without injury, the actual temperature with the wind-chill, what are the proper clothing items for each participate, does the training area allow for a place to warm up and can a watchful eye be maintained over all participates. Well trained coaches should be aware of the effects cold weather will have on each participate and their tolerance limits to exposure. One very important factor to look at when prepare to train in cold weather is attire. It is important to dress for the weather conditions, but it is even more vital that participants not over dress. The most common misconception when it comes to dressing for cold weather is that more is best. It is dangerously wrong to over dressing for the cold. Excessive clothing during weather exposure can lead to injuries ve... ... middle of paper ... ... strength, endurance and power. 5. The similarities between detraining and spaceflight are to say the least comparable. The reasons for the effects of spaceflight are even more complex than that of detraining. During flight astronauts go through changes in the muscular strength and mass, similar to that of injured athletes, yet at an even fast rate. The muscles that keep the body upright on earth decline in strength and mass inevitably to allow the body to respond appropriately to microgravity. The rate at which strength and mass are loss again depends on the physical condition of the astronauts and the length of continued exposure to microgravity. The body makes these adjustments in order to meet the demands of microgravity. References Wilmore, J. Costill, D. Kenny, W. (2012). Physiology of Sport & Exercise (5th ed.)

In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.

Being hypothermic or having frostbite on any part of your body can be very dangerous. This is an interesting topic because it can happen to anyone at anytime and if your are not prepared for it, it can be life threatening. If you are just going out to play in the snow and you are not dressed warm enough or all your skin is not covered frostbite can develop and you are at risk of hypothermia. Even if it is not snowing and there is not a cloud in the sky you can develop hypothermia if it is cold enough. If you are going to go hiking or skiing you will want to be aware of what hypothermia is and what to do if you get frostbite as this can result in the amputation of limbs and fingers. When skiing up in Vermont over Christmas break while going down the mountain my fingers started hurting and they were very cold. My dad and I were going down to the base of mountain, it was our final run of the day. We were skiing in negative 20 degree weather. This sparked my interest in hypothermia and frostbite because if we had not decided to get off the mountain frostbite developed on my hands and fingers and I would have run the risk of maybe getting them amputated. The purpose of writing this paper is to show how dangerous and lethal hypothermia and frostbite are if not taken care of properly.
Snowboarding, one of the hardest snowsport to learn but easy to master, it's also one of the most enjoyable snowsport on the planet. Even though it’s fun, you can really injure yourself if your not careful. In this narrative you’ll witness the pain I had to go through trying to learn snowboarding but also witness me mastering this incredible sport. It was a cool afternoon in the frosty month of January, the time was around 5:30 pm and my dad just dropped me off at Snow Valley hill in his black Mitsubishi Lancer. I took my blueish green Burton Custom snowboard from the back of the car, grabbed my helmet, gloves, jacket and snowpants and went to the bottom of the hill. There I placed my board on the soft snow and put on my gear. I was wearing a blue jacket with dark

While seniors, children, and people with chronic medical conditions may develop symptoms sooner, everyone is at risk as temperatures rise. “During a heat wave, you really shouldn’t be active outdoors during the hottest parts of the day,” he said, “but here in Arizona I am still amazed to see some golfers out on the course in the blazing afternoon sun.”

One major concern of prolonged exposure to microgravity is muscular atrophy. Muscular atrophy is the condition of losing the proteins that make up muscle cells, leading to degradation of muscles (“Muscle Atrophy” 1). This loss of muscle cells happen when muscles are not used,

In the awe-inspiring event of man experiencing interstellar travel many detrimental problems arise. Before 1970, the majority of biomedical studies on space flight were conducted immediately before and after flight. They examined the changes and readaptation processes for astronauts from a weightless to a gravitational environ-ment. After the successful Skylab space station projects from 1973-1974 and the Soviet Salyut missions from 1977-1982, biomedical research and experiments commenced in space. These experiments in space have shown that the physiological aspects can be deadly if not prepared for correctly and adequate medical support is not available. Although problems due to weightlessness and lack of exercise have been thoroughly researched and new machines and procedures have been developed to overcome these difficulties, there is still the opportunity to further understand weightlessness.
When exercising in the cold, people should consider these important factors for their safety. Do not overdress. Overdressing can cause the body to become hot and sweaty. Then the sweat soaks through the clothing, evaporating and removing the heat, and heat is lost even faster. (Kenney, 11/2011, p. 301) However, "People who have more fat mass conserve heat more efficiently than smaller, leaner individuals in the cold" (Kenney, 11/2011). I always thought this was just a myth to hurt fat people. Then I noticed how I would be comfortable in cooler temperatures then my partner. As you probably figured out she is
Physiological responses can be analysed in the term of immediate (acute) or long term (chronic) responses. Training routines are aimed at improving both of these. Acute responses are considered to be fast acting, therefore, they are called immediate while long term responses influence the athlete’s performance (Steele J, 2012). Chronic responses which also comes under the word of adaptations, and happens when training occurs, the changes are permanent while an athlete
Heat illness is the general term that refers to the symptoms that can develop after a person is exposed to high temperatures. Heat illness develops when the body cannot keep itself cool. Heat illness includes several heat-related conditions, such as heat exhaustion and heat stroke.
