2 3 SC-520.qxd 7/11/06 9:15 AM Page 5 Why Should I Monitor My Body Composition? Typically, total body weight is used to determine if a person is at a healthy weight. A change in weight alone does not tell you whether you have a gain/loss of muscle or fat. In weight management, you want to maintain muscle mass while body fat is lost. How Does This Body Composition Scanner Work? This unit uses BIA (Bioelectrical Impedance Analysis) to measure Body Fat, Body Water, Muscle Mass and Bone Mass. BIA sends a low intensity signal through the body. The signal is very low and causes no bodily harm. The signal flows with a different degree of difficulty depending upon the individual’s body fat level. This difficulty is called electrical impedance. Who Can Use This Body Composition Scanner? This HealthStation is designed for individuals aged 10 – 99 years. WARNINGS: DO NOT use this product if you have a pacemaker or other internal medical device. This product is not intended for use by children under 10 years of age or pregnant women. The measurements provided are not substitutes for physician assessments of bone mineral density or osteoporosis. Always consult your physician to determine what is right for you. When Should I Use This Body Composition Scanner? For maximum accuracy and repeatability, it is recommended that the unit’s functions be used at approximately the same time of day under the same circumstances, such as first thing in the morning before you step in the shower. It is also a good practice to avoid swings in the body’s hydration level prior to taking the measurement. By establishing the pattern of your body’s fluctuation over a period of one month, you can determine your average level of body fat, body water, muscle mass and bone mass. Women will have more fluctuation in water content than men and need to monitor their reading over a longer time period to establish a personal average. You must determine this as a reference point before measuring progress in a health program. You must wait several hours before taking a reading when: drinking coffee or alcohol, taking diuretic medications or exercising. These affect your level of hydration accuracy of this scanner. This instrument is a personal monitor and should be used in a consistent the most accurate reading. While readings may vary between this methods of measurement (hydro-densitometry or hand held calipers), body fat, body water, muscle mass and bone mass shown by this instrument will reflected accurately. 4 What Is Body Fat Percentage? Every body carries two types of body fat: essential fat and storage fat. Essential fat is needed for normal, everyday physiological functions within the human body. Storage fat is found just below the skin’s surface. Though some storage fat is necessary for normal body functions, excessive amounts can be detrimental to your health and overall quality of life. Use this chart as a guide: Note: Ideal body fat content is not the same for all people. Age, sex and heredity are variables in this measurement. Always consult your physician to determine what is most ideal for you. † † † Source: University of Illinois Department of Food Science and Human Nutrition. Body Fat Percentage Calculator. Your goal in weight loss should be to increase lean muscle mass and fat for a higher burning metabolism and improved body tone. 5 SC-520.qxd 7/11/06 9:15 AM Page 7 Why Is It Important to Monitor Your Total Body Water (TBW%) Percentage? Monitoring the level of body water can be a useful tool for one’s health maintenance. Water is an essential component of the body and is one of the body’s overall health indicators. Water makes up approximately 50-70% of the body’s weight and is present proportionally more in lean tissue as compared to fat tissue. For example: • 73% of lean muscle tissue is water • 80% of blood is water • 25% of fat is water • 22% of bone tissue is water Additionally, water is also a medium for biochemical reactions that regulate body functions. The estimated TBW% may vary according to your hydration level. For better accuracy, avoid fluctuations in hydration level prior to taking a measurement. The accuracy of the unit in estimating TBW% will also decrease with individuals suffering from diseases or illnesses that tend to accumulate water in the body. Please remember that the unit represents only a good approximation of your total body water. The normal TBW% of an individual varies according to body fat percentage and gender. The table below may be used as a guide: Rango de % BF Rango nor mal de TBW% Hombres 4 a 14% 70 a 63% 15 a 21% 63 a 57% 22 a 24% 57 a 55% 25% y m‡ s 55 a 37% 4 a 20% 70 a 58% Mujeres 21 a 29% 58 a 52% 30 a 32% 52 a 49% 33% y m‡ s 49 a 37 % †† Source: Derived from Wang & Deurenberg: “Hydration of fat-free body mass”.
