A fitness assessment is a systematic problem solving method that provides a basis for making educated decisions about exercise. Fitness assessments provide an ongoing gathering of information, allowing individuals to know where to start with an exercise program and how to modify and progress their exercise routines in a systematic fashion. By gathering information, through the fitness assessment, a fundamental representation of an individual’s goals, needs and status can be created. However, it is important to understand that a fitness assessment is not intended to replace a medical examination. Use a variety of observation methods to obtain a balance overview. Physiological assessments provide a wealth of information regarding overall health. Examples: heart rate and blood pressure Resting heart rates – avg. 60 – 80 bpm… lower resting heart rate-stronger and more efficient heart. Performing cardiorespiratory exercise the heart must adapt, much like muscles of the body adapt and become stronger from resistance training. A stronger heart will grow in size and pumps more blood with fewer strokes improving cardiac output. In fact, many elite athletes will have a resting heart in the 40s. Amazingly, cyclist and 7 time Tour de France winner Lance Armstrong has been measured as having a heart 33% larger than the average males, and a resting heart rate of 32. The resting heart can be taken on the inside of the wrist – radial pulse, or on the side of the neck – carotid pulse. To gather an accurate recording, it is best to perform when completely rested such as in the morning upon rising from bed. Radial pulse - Lightly place 2 fingers along the arm in line and just above the thumb. Once a pulse is identified, count for 60 seconds. Carotid pulse – lightly place 2 fingers on the neck, just to the side of the larynx. Once a pulse is identified, count for 60 seconds. When measuring the carotid pulse, excessive pressure can decrease heart rate and blood pressure, leading to an inaccurate reading, possible dizziness and fainting. Therefore the radial pulse is the preferred method for gathering a resting heart rate. Blood pressure – cause stroke, heart attack, kidkey failure, hart failure…. Silent killer Systolic reading, top number, --- pressure produced by the heart as it pumps blood to the body. Normal=120 mm of mercury to 130 mm of mercury. Diastolic reading, bottom number, ---minimum pressure within the arteries through a full cardiac cycle. Normal = 80 to 85 mm of mercury Blood pressure is measured using a sphygmomanometer and a stethoscope or with a home digital monitor.

Body composition assessments – determine if an individual’s weight and fat percentages are in healthy or unhealthy ranges. Individuals with too much fat, especially in midsection, have higher risk for high blood pressure, high cholesterol, and diabetes which increases risks for heart disease and stroke. Some common body composition assessments = body mass index, underwater weighing, skin fold assessments,
