ShareBody Surface Area (BSA)
Body Surface Area (BSA) is the total surface of the human body. This measurement is used in the medical field to help determine the appropriate dosages of medicine and the amount of IV fluids that need to be administered.
Body Surface Area has many different formulas for calculating the number, each with slightly different results. The most commonly used formula now is that of Mosteller, published in 1987 in The New England Journal of Medicine. Mosteller’s derived a simplified calculation in metric terms. The body surface area = the square root

ShareBMI (Body Mass Index)
Body Mass Index (BMI), is a general “rule of thumb” measurement to estimating human body fat based on an individual’s weight and height. BMI offers a correlation to other direct methods of measuring body fat, but BMI does not actually measure the percentage of body fat. Basically BMI offers a reliable indicator of body fatness.
BMI is an inexpensive and easy method that can be used as a screening method for unhealthy weight categories that may lead to health issues.
BMI is defined as the individual’s body mass divided by the

ShareATP and Energy Transfer Processes
ATP and Energy Transfer Processes supplies the energy to perform every bodily action. ATP is required for every muscle contraction, and ATP is even needed to make more ATP. In my article What is ATP, I discusses what ATP is in depth.
A high-level view of what ATP is and does is that ATP (Adenosine Triphosphate) is needed for practically every action in our body. Or put another way, ATP is the energy source for all human movement. Through the digestive process energy is released from the nutrients

ShareWhat is ATP?
What is ATP is a question that I get asked a lot. Most athletic have an understanding of what ATP is and that it provides the energy they need to perform. In my article Food: Nutrition Absorption and Delivery I discussed that after we eat a meal, the nutrients are digested, absorbed and screened by the liver and then sent into the bloodstream of the body to reach target cells. Once the nutrients reach their target cells a number of things can happen such as: 1) they are oxidized for

ShareFood and Nutrition Absorption and Delivery
Food and nutrition go hand-in-hand, and in this article we will take a look at how nutrients are absorbed and delivered throughout our body. Eating food is a daily activity that we partake in multiple times per day. Most of us are not concentrating on the nutritional value and the nutrients that are in the food, we are concentrating on the food itself and how it tastes. However, if you want to move close to living a fitness lifestyle, it is important to understand how food and nutrition interacts

ShareProteins: A Look at the Cellular Level
Proteins are an important component of every cell, tissue, and organ in our body. Proteins are the building block of bones, muscles, and more. In my article Good Nutrition and Nutritional Science I discussed how good nutrition effects our body at the cellular level. And I also discussed that it is at this cellular level that nearly every function that takes place in our bodies is dependent on the creation and production of proteins.
Let’s take a closer look at these cellular proteins and how good
