Our Energy Production and Its Daily Requirement

Our body requires energy for its metabolic and physiological functions. It derives the energy from food and its macronutrient constituents, i.e. carbohydrates, fats, and proteins. The dietary energy intake from food must meet the requirements for the attainment and maintenance of optimal health, physiological function, and well-being.

The energy requirement is the amount of food energy needed to maintain body size, body composition, and a level of necessary physical activity consistent with long-term good health. The dietary energy needs cannot be considered in isolation of other nutrients in the diet, as the lack of one will influence the others. Thus, the requirements for energy must be fulfilled through the consumption of a diet that satisfies all nutrient needs.

Mitochondria are found in the cytoplasm of all eukaryotic cells, that is, the cells with clearly defined nuclei. Their primary function is to generate large quantities of energy in the form of adenosine triphosphate (ATP). The number of mitochondria per cell varies widely.

ATP, the energy-carrying molecule, is found in the cells of all living things. When ATP is broken down, energy is released and can be harnessed for cellular work. Because ATP is so easily broken and reformed, ATP is like a rechargeable battery that powers cellular processes.

ATP is often referred to as the “molecular unit of currency” of intracellular energy transfer. ATP captures energy obtained from the breakdown of the food and releases it to fuel the cellular processes. Our body regenerates and recycles its own body weight equivalent in ATP each day.

Daily energy requirements –

There are only small amounts of ATP in the body. Therefore, it is necessary to have sufficient energy stores for backup. The amount of daily energy requirement depends on an individual’s daily energy consumption and metabolic energy requirement, which depends on one’s body weight and activity level.

The energy we get from food to fuel our body, is measured in kilojoules. Fat, carbohydrate and protein, which are found in foods, all provide energy.

The basic energy consumption of the human body is 4 kJ/kilogram of body weight per daily hour. So an individual’s basic energy consumption can be calculated as follows:

Total Energy Consumption = Body weight (Kg) × 4 KJ × 24 hours/day / 4.18 kJ

The total energy consumption value is divided by 4.18 kJ in order to convert the value into kilocalories (1 kcal = 4.18 kJ). This calculation represents daily energy consumption.

Individual energy requirements vary with age, gender, body size and activity levels. Excess food intake that is not used as energy can be stored in the body as fat. Excessive fat storage can lead to a high body mass index (BMI).

BMI indicates a person’s body fat and is determined by an individual’s height and weight. In adults, the normal suggested BMI ranges between 19 and 24. A high BMI can potentially lead to illness or health complications. In order to have an ideal BMI, an individual’s energy intake must not exceed the energy burned on a regular basis.

Energy balance –

Energy balance is the relationship between calories taken into the body through food and drink and calories being used in the body for our daily energy requirements.

When you take in more calories than you consume, you are in a positive energy balance. When you take in fewer calories than you consume, you are in a negative energy balance. You energy balance affects your metabolism, hormonal balance, and mood.

A negative energy balance leads to weight loss. The body detects an energy deficit and fat reserves are called upon to make up the difference. A positive energy balance has its own ramifications not only in terms of weight gain but also in terms of health and fitness.

Aerobics: Targeting The Abdomen

Very Important

Getting your exercise is always important. This should be something that you already know, but what you might not know is that type of exercise that you are getting is just as important as actually getting it. To be completely healthy, you have to get all of the types of exercise that you need, and you have to be sure that you are getting them all in the right way. Aerobic exercise along with anaerobic exercise is the best way to make sure you are getting all parts of the work out that you need. When it comes right down to it, aerobic exercise along with anaerobic exercise is a great combination. You are getting your heart rate pumping with the aerobic exercise, and with the anaerobic exercise, you are allowing yourself to do strength training, which is also very important for your body’s health.

With all of the types of exercise out there, you can make sure that your exercise regime includes aerobic exercise along with anaerobic exercise because this is going to be the healthiest way you can get the proper amount of exercise in general.

If you are concerned about aerobic exercise along with anaerobic exercise and you don’t know what kinds of exercise you should be doing, you need to check with your doctor because after all your doctor knows the most about your body and what you can do to feel and look better with who you are. Your doctor can give you the correct combination of aerobic exercise along with anaerobic exercise and make sure that you are getting enough of both types of exercise in your daily routine. In short, aerobic exercise will help you to build heart and lung health and burn fat, while anaerobic exercise will help you build muscle.

We all know that working out is very important for us to be doing. You are going to want to get a workout so that you can be healthier, and so that you know what you are doing when it comes to getting a better outlook on life. Most of the people who get depressed and unhealthy aren’t doing aerobics, so no matter what your level of health is, aerobics are going to be good for you.

However, sometimes it is important to target more than one area when it comes to aerobics. You might want to work on something in particular. Often, people have parts of their bodies that they don’t like as much as others, and this can be very stressful. Most of the time, workouts seek to make your whole body stronger, and while this is important, if you have a problem area, you might feel like you want to work out it.

Targeting The Abdomen

To target the abdomen while you are doing aerobics, you must remember what the abdomen is and why it is important. It is not just your tummy area; this is a whole range of muscles that help you move and stretch in every piece of your daily routine. This is why targeting your abdomen during aerobics is very important.

When you are looking at targeting your abdomen, think first of repetitions. The best way to work on your abdomen is to add stretches into whatever you are doing aerobically. If you are walking or running in place, you should be stretching your body and stretching from side to side as you move. You have to be sure that the movement you are making is coming from your abdomen, however. It is all too easy to move your arms and legs and thinks that you are stretching your abdomen.

Another great thing that you can do while you are doing your aerobics is to kneel and to then use your abdomen muscles to move up and down into different positions. Remember that you have to keep doing repetitions at a high enough rate of speed to keep your heart rate up. The more that you move, the better in shape you are going to get. This is a great way to target your abdomen. Again though make sure that the movements are coming from your tummy area.

Remember that it is not a good idea to only get one type of exercise, no matter how strong you think you are. To be healthy you have to be sure that you are getting aerobic exercise along with anaerobic exercise to have a well-rounded level of health. This can be your best shot at being competently healthy because it is only by getting both types of exercise that you are allowing your body to have full control over its movements and to be fully in control of how healthy you are. Remember always that aerobic exercise along with anaerobic exercise is the best way to go – you don’t want to leave one type out.
