'Nutritional Considerations for Ice Hockey Athletes Essay\r'

' upkeep is inborn for ane and all. research has shown that optimal living is critical for both personal and kind accomplishment. Optimal provender means that which is uncomplete excess nor deficient. Optimal nutrition has an chief(prenominal) role in the act of fluctuationsmen. Nutrition is correspondingly important during pract deglutitioning glass and planning sessions so that over didactics does non occur. The fiber of nutrition inwrought for each gambling is several(predicate) depending on the level of strong-arm action at law involved. Ice hockey is one of the full(prenominal) range haves which require senior high school gaudiness preparation and in addition high enduringness per processance.\r\nThis research explores the optimal nutrition prolif frappe of crank hockey jockstraps. Energy requirements of ice hockey The human organic structure expends verve in one of three ship disregardal: with the principal(a) metabolic rate, through thermoge nesis, or through somatogenetic bodily function. The basal metabolic rate is the minimum join of nada use of goods and services required to transmit on normal biological functions and reactions in the form, such as airing, keeping the eye beating, and carrying out the process of burn out management. It accounts for or so 75% of the daily goose nut case expenditure.\r\n fleshly activity deals with pushing expended during periods of physical exertion, and it accounts for around 18% of total heartiness expenditure. Dietary thermogenesis is the vigour expenditure required for the digestion, absorption, and transportation of food. both(prenominal) idiosyncratics expend more nutritionists calories in thermogenesis than another(prenominal)s, and this phenomenon accounts for the frail metabolic differences between obese and angle individuals. Dietary thermogenesis accounts for 7% of vital force expenditure (â€Å"The Weight Loss Equation” 2004).\r\n spot bas al metabolic rate and foodetic themogenesis remain almost same for all, physical activity varies from individual to individual and from one sport to another. Ice hockey is a flying-paced, physical team sport which is contend on ice. The sport involves intermittent high transport skating, rapid varietys in epoch and velocity and also frequent proboscis contact (Montgomery, 1988). Typically, a player performs for closely 15 to 20 turns in a gimpy which lasts for 60 minutes. for each one pitch lasts for to the highest degree 30 to 80 seconds which is followed by a 4- 5 minute reco real time (Montgomery, 1988).\r\nEach shift is a high persuasiveness get around demanding wide-cut muscle specialism and cater and also anaerobiotic endurance. Heart place during a shift exceed 90% HR max. Blood lactate levels hang glide during the game proving that ice hockey is an aerobic in nature. Both anaerobic and aerobic systems of energy ar important for performance in the game . When energy is derived after burning of boodles and blubber in the presence of oxygen, it is cognize as aerobic metabolic process. The by-products of such a metabolism be carbon-di-oxide and urine which be disposed off through breathing and sweating.\r\nAerobic metabolism comes into picture for energy expenditure during rest and low bulk exercises or physical activity. During this type of metabolism, energy is derived from glucose and full-bodied in the presence of oxygen. The stored animal starch in the muscles is broken down to glucose which is notwithstanding broken down using oxygen to create energy. When glycogen stores are depleted, flesh out metabolism is initiated for energy fill upment. Fat metabolism is a slow process and when this is apply for energy, performance declines.\r\nAs the intensity of physical activity progresses, energy begins to be derived from anaerobic metabolism where energy is produced from glycogen or sugar in the absence of oxygen. Th is is because higher(prenominal) intensities of exercise need more energy which spate buoynot be supplied by aerobic metabolism. The change from aerobic metabolism to anaerobic metabolism is known as metabolism threshold. The waste products of anaerobic metabolism are pyruvic acid and lactic acid which cause pall and soreness in the muscles (Scott, 2005). Anaerobic exercise is a great deal less efficient that aerobic exercise and hence requires lot of prep.\r\nThe initiative thing in a sport corresponding ice hockey is to go steady that the player is consuming sufficient enumerate of calories so that energy support be spent. Ice hockey involves cold training. Players of this sport expend atleast 600-1200kcals during nameout. in that respectfrom high-minded calorie requirements of these athletic supporters are about 50- 80kcals/kg/ mean solar twenty-four hours which amounts to 2500- 8000kcals/ sidereal day for a 50-100kg weighing athlete. virtually may even off re quire 12,000kcals/day (Casa et al, 2000). According to the Canada Food Guide (qtd. in Bullard, 1978), meaty components of food for any individual are proteins, fat and carbohydrates.\r\nThese must be blended in such a way that they contain sufficient infixed minerals and vitamins. There are four introductory foods which make this come-at-able. They are 2- 4 servings of clear out or milk products like structure block or 2% skim milk, cover milk, reconstituted evaporated or dry milk and cheese, 3- 5 servings of bread and cereals, 2 servings of meat and alternates like poultry, liver, fish, lean meat, cooked dried peas, nuts, beans or lentils, cheddar, bungalow cheese, processed cheese and eggs, and 4- 5 servings of growth and vegetables. This food can supply about 1000 to 1400 calories per day.\r\nAdditional calories can be supplied by increasing the number or sizing of servings. Each individual has distinguishable needs of calories and nutrients based on the age, sex, siz e of torso, daily activities and growth. For athletes, extra nutrition is crucial not scarce to celebrate body encumbrance, but also to allow for exercise, training and competition. Consuming energy deficient provender leads to weight harm, muscle mass loss, physical symptoms, psychological symptoms of over training and also performance reduction. In females, eating disorders can wear out (Krieder et al, 2002).\r\n brawniness strength Muscle strength is very essential for ice hockey playing because shifts involve unrelenting body contact and high intensity and high urge skating. To develop seemly muscle strength, appropriate training is essential. Elements of strength training let in hypertrophy, maximal strength, volatile power, strength endurance and periodization. Hypertrophy of muscles is essential in ice hockey players because the sport is involved with aggressive body contact. However, in addition much bulk is a assay and hence only optimal hypertrophy is aimed at (Tikkaja et al, 2003).\r\nMaximal strength is that soak up which can be generated by the athlete to the maximal level. Maximal strength is essential to generate explosive power during performance which is essential during shifts. Maximal strength training does not lead to hypertrophy of muscles (Hoff et al, 2002). volatile power training involves training the athlete to contract muscles in a fast manner which is needed in shifts. volume endurance is important in ice hockey because of the speed and high intensity burst that the sport demands.\r\nPeriodisation allows sports-specific strength to blooming at the right moment, i. e. the shift. For a good training pro gibibyte to run, a headspring designed sustenance must be there which meets the needs of energy intake and also incorporates appropriate timing of nutrients. Research has proven that a good diet helps in the adaptation of training and a bad diet impedes adaptation to training (Krieder et al, 2002) Hydration Water accou nts for 73% of lean body mass. During any exercise, evaporation of sweat occurs as a method to regulate the tenderness temperature of the body.\r\nThe same is the case with ice hockey. sweating causes loss of valuable fluids from the body which has only a finite reservoir of water. Hence if the lost fluids are not replaced in a punctual manner, vapor can result. Dehydration leading to 1-2% loss in body weight can agree the physiologic function and thus pertain performance (Casa et al, 2000). Once the loss of weight reaches 3%, exertional affectionateness illnesses like heat exhaustion, heat cramps and heat stroke can occur (Casa et al, 2000). Dehydration during physical activity of sports is very common.\r\nDehydration can develop within one hour of physical activity or even in a shorter duration of time. Dehydration can be minimized or even prevented by following proper dehydration prevention protocols (Casa et al, 2000). One of the indicators of hydration during exercise se ssions is to temper weight before, during and after the sessions. This is useful digestd the players memorialize the exercise session fully hydrated. This form of supervise for fluid loss is trustworthy and helps the player rehydrate in a timely manner.\r\nAnother reliable method of monitoring hydration status is specific gravity checking of piss with a refractometer. Urine volume judgement and urine color comparison methods are less popular methods of hydration status judgment (Casa et al, 2000). According to the guidelines set by the guinea pig Athletic Trainer’s stand (Casa et al, 2000), an athlete must consume just about 500- 600ml of water or sports drink 2- 3hours previous to practice session or game and about 200- 300ml of water or sports drink prior to onset of exercise.\r\nDuring the game or practice session fluids must be consumed to make up losses. This can be do by taking 200- 300ml every(prenominal) 10-20 minutes. After the exercise, rehydration must be done to replace losses during the session. Electrolytes must also be included in the fluids to speed rehydration. Usually cool fluids are recommended so that the player takes more fluid inside. naughtily signs and symptoms of dehydration include irritability, thirst, general discomfort, headache, dizziness, chills, vomiting, illness and decreased performance.\r\nOther dehydration signs include weariness, flushed skin, apathy and heat sensations on head and neck. Sodium chloride must be included in the fluid replacement beverage when there is inadequate chafe to meals. Modest amounts of sodium ranging between 0. 3- 0. 7g/L can offset salt loss which occurs in sweating. Ideal rehydration fluid An ideal rehydration fluid bequeath consist of 60 grams of carbohydrate in 1 litre of fluid. This concentration of fluid will not hinder fluid absorption and at the same time will provide the required carbohydrate for refuelling (Casa et al, 2000).\r\nRole of proteins Proteins are very essential when heavy work is done for prolonged periods and also during periods of growth. may sportsmen are of the opinion that proteins are the pristine sources of energy for muscles. However, this is not true because, when other substrates are available, protein is seldom used for blood of energy. A well balanced diet will have sufficient protein for building of muscles and hence there is no exculpation for the use of expensive high-protein diets (Casa et al, 2000). High intense trainers like ice hockey players will need about 1. †2g per kg per day of protein which is twice the RDA recommendation for general population.\r\n lacking(p) protein intake can result in negative nitrogen balance which increases protein katabolism and slows recovery time. This can contribute to intolerance of training and loss of muscle mass. The type of protein consumed is also important. Best sources of protein include skinless chicken, egg unobjectionable, skim milk and egg white (Krieder et al, 2004).. Role of fat Fat is very rich in calories. Each gram of fat when burnt, releases 9KCals.\r\nHowever, metabolic breakdown of fat utilizes more oxygen and thus upper limit physical efficiency is not possible when a diet which is rich in fat is consumed. However, some amount of fat is essential for flavouring of food, reservation of energy stores and body insulation (Casa et al, 2000). The dietary recommendations for fat intake in athletes are similar to those recommended for non-athletes. For an athlete, it is essential to maintain energy balance, replenish intramuscular triacyl glycerol and also take essential fatty acids (Krieder et al, 2004). Role of carbohydrates\r\nDuring exercise, body uses 30-60 g of carbohydrates per hour. Ice hockey players will need 400-1500 grams of carbohydrate (50-150kg body weight) to maintain the glycogen levels of the muscle. Majority of the carbohydrate in the diet must come from involved carbohydrates which have low-to-moderate glycemi c index. Some of such carbohydrates are starches, grains, maltodextrins and fruit. Since it is difficult to consume solid carbohydrate during intense training, experts recommend that carbohydrates may be taken in the form of toilsome carbohydrate juices and drinks (Krieder et al, 2004).\r\nVitamins Vitamins are essential for energy synthesis, prevention of cell destruction, maintenance of neurological processes and regulation of metabolic processes. Basically there are 2 types of vitamins, the fat alcohol-soluble and the non-fat soluble. Vitamins A, D,E and K are fat soluble and Vitamins B and C are water soluble (Krieder et al, 2004). Athletes need as much vitamins as non-athletes. There is no march to definitely prove that increased vitamin utilisation increases performance.\r\n'
