Russell Smith 7th January 2011 Energy Balance Energy balance plays a vital role in good health, weight management, energy levels, recovery, and sports performance. Maintaining the correct energy balance for your sport can make the difference between success and not reaching your potential. It is important to make sports performers aware of how significant energy balance can be. Energy intake is the total number of calories ingested daily, where as Energy expenditure is the total number of calories used daily. There are four different aspects of expenditure these include, basal metabolic rate this is the amount of daily energy expended while at rest in a neutrally temperate environment, dietary thermogenesis this is how many calories your body burns through digesting absorbing and using food, adaptive thermogenesis this is production of heat in response to environmental changes in temperature and finally physical activity which consists of any physical movement. Energy Imbalance between intake and expenditure consists of gaining and losing imbalance. Gaining imbalance is a result of energy intake being higher than what is consumed in external work and other means of energy expenditure.
Our BMR demands around two-thirds of or daily energy intake required for every day activities and is the largest part of our daily energy expenditure. By using body mass, height and age it allows us to get an accurate estimate of our BMR. This helps us to monitor body weight and is a practical way of assessing energy balance. Weight stablility is very important for athletes during sports performance as it allows them to see whether their energy requirements are being met, also by monitoring body weight before and after exercise training sessions allows athletes to assess their performance. Deliberate weight loss of gain is used to enhance athletic performance, and is usually done off-season as not to affect their performance in competition. Weight loss during peak season can give athletes an inadequate amount of energy, carbohydrate and fluid intake where as weight gain in the form of body fat can compromise endurance, speed and power. Energy balance is a state where energy intake is equivalent to energy expenditure, resullting in no weight gain or loss.
One disadvantage for it is for some sports, an individual would not have enough energy. For a negative energy balance sports such as wrestling, boxing and weight lifting allow a performer to assess whether they are within the right weight category. Disadvantages include major health risks because not enough nutrients, minerals and vitamins are provided to the body therefore quickening the process of fatigue and lowering energy levels. Also, losing weight can be mentally draining for the performer causing a shorter attention span and lowering alertness. Although advantages are an individual will look aesthetically pleasing, therefore this can improve over all confidence. Also as I stated before it makes it easier for the person to make their weight category. Finally, for a positive energy balance sports such as boxing and horse riding allow a performer to improve performance, muscle size and strength which are the main advantages. However it can raise BMI, cause obesity, cause disease as well as putting pressure on organs which are all disadvantages. Overall, Energy balance is very important for a sports performer, as it enables them to maintain the correct weight and proportions to keep a good level of endurance, speed and power that is needed for a good performance. ?? ?? ?? ??
