Jooule Energy Sources
Calories:
The name calorie is used for two units of energy. Although these units are part of the metric system, they have been superseded in the International System of Units by the joule. One small calorie is approximately 4.2 joules. Calories are also most known to be used in foods and diet, which is key to athletes.
Joules:
A Joule is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre.
Kilocalories:
Kilocalories are 100 calories
Kilojoules:
Kilojoules is 100 joules of energy.
Energy sources:
Fats:
Fat provides the highest concentration of energy of all the nutrients. One gram of fat equals nine calories. This calorie density, along with our seemingly unlimited storage capacity for fat, makes fat our largest reserve of energy. One pound of stored fat provides approximately 3,600 …show more content…
How long this energy supply lasts depends on the length and intensity of exercise and can range anywhere from 30 to 90 minutes or more. To avoid running out of energy during exercise, start with full glycogen stores, replenish them during exercise and refill them after exercise to be ready for the next …show more content…
Metabolism refers to the processes that the body needs to function. Basal Metabolic Rate is the amount of energy expressed in calories that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles. Basal metabolic rate affects the rate that a person burns calories and ultimately whether you maintain, gain, or loses weight. Your basal metabolic rate accounts for about 60 to 75% of the calories you burn every
