Kris Lee asked:

Fitness, itself, is composed of four different elements: cardiorespiratory endurance, muscular fitness, flexibility, and body composition.

Cardiorespiratory endurance, or aerobic fitness, relates to the body’s capacity to absorb, transport, and use oxygen during work or exercise. As the body is trained to endure a greater cardiovascular workload, the heart and lungs become stronger thereby increasing an individual’s endurance. A marathon runner would be a prime example of an athlete with a high level of aerobic conditioning.

Muscular fitness can be best described as a balance of strength and endurance. Muscular strength is the body’s ability to generate force at a given speed of movement. Muscular endurance refers to the ability of the body to repeat movements and resist muscular fatigue. A better way to distinguish between muscular strength and endurance would to imagine lifting a fifty-pound weight just one time-strength-versus lifting a five-pound weight ten times-endurance.

Flexibility is often the most overlooked component of physical fitness. Flexibility is the range of motion around a joint or a group of joints. Range of motion is limited primarily by the amount of soft tissue, including muscle and the joint capsule, surrounding the joint. A gymnast would rely on his or her flexibility as well as strength to complete a strenuous tumbling routine without injury.

Body composition is the fourth and final component of fitness. There are two distinct elements with body composition: fat mass and lean body mass. Fat mass, as it implies, is the percentage of fat, both essential and nonessential, that makes up an individual’s body. Essential fat can be found in bone marrow, nerve tissue and in various internal organs.Woman have a significantly greater percentage of essential body fat, around 12 percent, than men, around 4 percent, due to the demands of child bearing. Nonessential fat can be found subcutaneously, or beneath the skin, and is primarily used for excess body fat storage. “Based on data from physically active young adults, it would be desirable . . . to strive for a body fat content of 15% for men (certainly less than 20%) and about 25% for women (less than 30%)” (McArdle et. al. 1996, 570). Lean mass, on the other hand, is comprised of everything in the human body other than fat, such as muscle mass, bone mass, and the weight of the internal organs. An ideal body composition, therefore, would be an individual possessing a healthy body fat percentage: 15-20 percent for men and 25-30 percent for women.

These four components are essential for maintaining optimal health and fitness while preventing injury and muscular imbalances. Imagine a long-distance runner who spends her training time running without any regard for strengthening or stretching.While her cardiorespiratory endurance and body composition are favorable, she neglects her muscular strength and flexibility and can possibly set herself up for serious injury in the future. Along similar lines, imagine an amateur bodybuilder who spends a large amount of time lifting weights and increasing muscle mass, but who neglects his cardiovascular health and flexibility. He, too, increases his chance of injury by ignoring two very important components of fitness.

While it is ideal to have a balance of cardiorespiratory endurance, muscular strength and endurance, flexibility, and a favorable body composition, it is not something that is easily attainable. Good health takes work, but it does not have to resemble work.

Healthy Weight Loss Advice – Understanding Body Composition

Body Composition Scale

It doesn’t matter what you weigh. Height and weight charts are meaningless. What really matters is the composition of your body – how much of your body is muscle and how much is fat. An understanding of body composition is one of the ways you’ll escape the gravitational pull of the diet mentality. Body composition is a much more sophisticated way to see your body. Forget the scales and the height and weight charts. Concentrate on body composition.
Body composition testing measures how lean your body is. Remember, getting lean means to enhance your lean body mass – your muscles, your bones, your organs and the fluids of your body. Body composition is the only accurate way to measure how lean you are.
We have a real challenge in this country. We live in the fattest nation on earth. The average American male is 26% body fat. The average American female is 36% body fat. Let’s put that in perspective. If this average male with 26% body fat weighs 200 pounds, it means he’s carrying around 52 pounds of fat. Fat is dead weight. Every pound of fat adds 7 miles to your circulatory system. Your body stores your toxins in your fat cells. The more fat you have on your body, the more toxic your body is.
Example. A person who is 50 pounds over his or her ideal body weight has a risk of cancer that is 18 times higher than the average. According to cutting edge research performed at Tufts University Medical School, the best single indicator of whether you’re aging successfully is your body fat percentage. The leaner you are, the more successfully you age. You can’t be too lean.
According to exercise physiology research what should your body composition be? Men should be 15% body fat or less regardless of age. Women should be 22% body fat or less regardless of age.
Fifteen percent body fat for men and 22% body fat for women will put you into good to very good health. What if you want excellent health? What if you want to be as healthy as you could possibly be? For male athletes or men who want excellent health, the range is 6 to 12% – regardless of age. For women it’s 12 to 18%.
How do you measure body composition? There are various methods. Hydrostatic weighing is the gold standard of body composition testing. It’s the most accurate, but not very practical. Skin fold calipers are nearly as accurate, a lot more practical, and a lot more comfortable for you.
Fat is stored in 3 different areas of our body. Subcutaneously – which is between the skin and the muscle. Intramuscularly – which is within the muscle (otherwise known as marbeling in steak). And, between your organs.
To obtain your body composition, it will be necessary to measure the thickness of your skin fold in 7 different locations on your body using a skin fold caliper. It will very accurately measure the thickness of your skin fold in millimeters. These numbers will be entered into a very complex mathematical formula that has been developed by exercise physiology research.
What will you learn? You’ll learn your body fat percentage which is a relationship between the amount of fat you have compared with your lean body mass. You’ll learn how many pounds of your total body weight are fat. And how many pounds are lean body mass. And you’ll learn your true ideal body weight. How is that calculated? The computer will take your lean body mass (your fat free weight) and add to that the optimal amount of body fat 15% if you’re a guy. 22% if you’re a gal. Now you have your true ideal body weight based on your body and not some height and weight chart.
Remember, you won’t always lose weight every week. But this is where the measurements really help. If you don’t lose weight, but your measurements get smaller, you’ve gotten leaner. Research reported on ABC-TV NEWS showed that adding just 5 pounds of muscle and maintaining it for one year automatically burns 91,250 calories! And burning 91,000 calories translates to losing as much as 26 pounds!
Remember, if you gain one pound of muscle and lose one pound of fat, your weight hasn’t changed, but you’re leaner.

Welcome to Body Composition Scale.

Welcome to BodyCompositionScale.net! Valhalla Scientific is the technology leader in professional Body Composition Scales. Our Body Composition Analyzer Scales or Body Fat Scales constitute a set of digital scales which are scientifically proven to be the equivalent of hydrostatic weighing scales for the accurate determination of Lean Body Mass, Body Mass Index or Fat Free Mass while providing Percent Body Fat Measurements using scientifically proven bio-impedance technology or bio-resistance technology.

A person’s total body fat percentage is the total weight of the person’s fat divided by the person’s weight. The resulting number reflects both essential fat and storage fat.

Essential fat is that amount of fat necessary for maintenance of life and reproductive functions. The percentage for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Essential fat is 2–5% in men, and 10–13% in women.

Storage fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. The minimum recommended total body fat percentage exceeds the essential fat percentage value reported above. A number of online tools are available for calculating estimated body fat percentage.

Arguably, body fat percentage is the superior gauge of an individual’s fitness level, as it is the only body measurement which directly calculates the particular individual’s body composition without regard to the individual’s height or weight. The widely-used body mass index (BMI), on the other hand, simply makes blanket assumptions as to what every individual of a certain height should ideally weigh, regardless of the body composition which makes up that weight. The BMI gives particularly inaccurate information with regard to individuals with above-average lean muscle mass, classifying such individuals as “overweight” or “obese” despite the fact that their body fat percentage would indicate they are in excellent physical condition.
