The Health-Related Components of Physical Fitness

Have a strong relationship with good health

Are characterized by an ability to perform daily activities with vigor

Are associated with a lower prevalence of chronic disease and health conditions and their risk factors

Copyright © 2014 American College of Sports Medicine

3

Purposes of Health-Related Physical Fitness Testing

Educating participants about their present health/fitness status relative to health-related standards and age and sex matched norms

Providing data that are helpful in development of individualized exercise prescriptions to address all health/fitness components

Collecting baseline and follow-up data that allow evaluation of progress by exercise program participants

Motivating participants by establishing reasonable and attainable health/fitness goals (see Chapter 11)

Copyright © 2014 American College of Sports Medicine

4

Basic Principles and Guidelines

An ideal health-related physical fitness test

Is reliable, valid, relatively inexpensive, and easy to administer

Should yield results that are indicative of the current state of fitness, reflect positive changes in health status from participation in a physical activity or exercise intervention, and be directly comparable to normative data

Copyright © 2014 American College of Sports Medicine

5

Pretest Instructions

A minimal recommendation is that individuals complete a questionnaire such as the Physical Activity Readiness Questionnaire (PAR-Q; see Figure 2.1) or the ACSM/AHA form (see Figure 2.2).

A listing of preliminary instructions for all clients can be found in Chapter 3 (“Participant Instructions”). These instructions may be modified to meet specific needs and circumstances.

Copyright © 2014 American College of Sports Medicine

6

Test Organization

The following should be accomplished before the client/patient arrives at the test site:

Ensure that all forms, score sheets, tables, graphs, and other testing documents are organized and available for the test’s administration.

Calibrate all equipment (e.g., metronome, cycle ergometer, treadmill, sphygmomanometer, skinfold calipers) at least monthly, or more frequently based on use; certain equipment such as ventilatory expired gas analysis systems should be calibrated prior to each test according to manufacturers’ specifications; and document equipment calibration in a designated folder.

Copyright © 2014 American College of Sports Medicine

7

Test Organization (cont.)

Organize equipment so that tests can follow in sequence without stressing the same muscle group repeatedly.

Provide informed consent form.

Maintain room temperature between 68° F and 72° F (20° C and 22° C) and humidity of <60%.

Copyright © 2014 American College of Sports Medicine

8

Test Organization (cont.)

Resting measurements should be obtained first:

Heart rate

Blood pressure

Height

Weight

Body composition

Copyright © 2014 American College of Sports Medicine

9

Test Organization (cont.)

Research has not established an optimal testing order for multiple health-related components of fitness (i.e., cardiorespiratory [CR] endurance, muscular fitness, body composition, and flexibility), but sufficient time should be allowed for HR and BP to return to baseline between tests conducted serially.

Because certain medications, such as β-blockers which lower HR, will affect some physical fitness test results, use of these medications should be noted.

Copyright © 2014 American College of Sports Medicine

10

Test Environment

Test anxiety, emotional problems, food in the stomach, bladder distention, room temperature, and ventilation should be controlled as much as possible.

To minimize subject anxiety, the test procedures should be explained adequately, and the test environment should be quiet and private.

The room should be equipped with a comfortable seat and/or examination table to be used for resting BP and HR and/or ECG recordings.

Copyright © 2014 American College of Sports Medicine

11

Test Environment (cont.)

The demeanor of personnel should be one of relaxed confidence to put the subject at ease. 

Testing procedures should not be rushed, and all procedures must be explained clearly prior to initiating the process.

Copyright © 2014 American College of Sports Medicine

12

Body Composition

Before collecting data for body composition assessment, the technician must be trained, routinely practiced in the techniques, and already have demonstrated reliability in his or her measurements, independent of the technique being used.

Experience can be accrued under the direct supervision of a highly qualified mentor in a controlled testing environment.

Body Mass Index

The BMI is used to assess weight relative to height and is calculated by dividing body weight in kilograms by height in meters squared (kg · m−2)

For most individuals, obesity-related health problems increase beyond a BMI of 25.0 kg · m−2, and the Expert Panel on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults defines a BMI of 25.0–29.9 kg · m−2 as overweight and a BMI of ≥30.0 kg · m−2 as obese.

18

Circumferences

The pattern of body fat distribution is recognized as an important indicator of health and prognosis.

Android obesity that is characterized by more fat on the trunk (abdominal fat) increases the risk of hypertension, metabolic syndrome, Type 2 diabetes mellitus, dyslipidemia, CVD, and premature death compared with individuals who demonstrate gynoid or gynecoid obesity (fat distributed in the hip and thigh).

Copyright © 2014 American College of Sports Medicine

19

Circumferences (cont.)

A cloth tape measure with a spring-loaded handle (Gulick tape measure) reduces skin compression and improves consistency of measurement.

Duplicate measurements are recommended at each site and should be obtained in a rotational instead of a consecutive order (take measurements of all sites being assessed and then repeat the sequence).

The average of the two measures is used provided they do not differ by more than 5mm.

Box 4.1 Standardized Description of Circumference Sites and Procedures

Abdomen: With the subject standing upright and relaxed, a horizontal measure taken at the height of the iliac crest, usually at the level of the umbilicus.

Arm: With the subject standing erect and arms hanging freely at the sides with hands facing the thigh, a horizontal measure midway between the acromion and olecranon processes.

Buttocks/Hips: With the subject standing erect and feet together, a horizontal measure is taken at the maximal circumference of buttocks. This measure is used for the hip measure in a waist/hip measure.

Calf: With the subject standing erect (feet apart ~20 cm), a horizontal measure taken at the level of the maximum circumference between the knee and the ankle, perpendicular to the long axis.

Forearm: With the subject standing, arms hanging downward but slightly away from the trunk and palms facing anteriorly, a measure is taken perpendicular to the long axis at the maximal circumference.

Copyright © 2014 American College of Sports Medicine

21

Box 4.1 Standardized Description of Circumference Sites and Procedures (cont.)

Hips/Thigh: With the subject standing, legs slightly apart (~10 cm), a horizontal measure is taken at the maximal circumference of the hip/proximal thigh, just below the gluteal fold.

Mid-Thigh: With the subject standing and one foot on a bench so the knee is flexed at 90 degrees, a measure is taken midway between the inguinal crease and the proximal border of the patella, perpendicular to the long axis.

Waist: With the subject standing, arms at the sides, feet together, and abdomen relaxed, a horizontal measure is taken at the narrowest part of the torso (above the umbilicus and below the xiphoid process). The National Obesity Task Force (NOTF) suggests obtaining a horizontal measure directly above the iliac crest as a method to enhance standardization. Unfortunately, current formulae are not predicated on the NOTF suggested site.

Copyright © 2014 American College of Sports Medicine

22

Box 4.1 Standardized Description of Circumference Sites and Procedures (cont.)

All measurements should be made with a flexible yet inelastic tape measure.

The tape should be placed on the skin surface without compressing the subcutaneous adipose tissue.

If a Gulick spring-loaded handle is used, the handle should be extended to the same marking with each trial.

Take duplicate measures at each site and retest if duplicate measurements are not within 5 mm.

Rotate through measurement sites or allow time for skin to regain normal texture.

23

Circumferences (cont.)

Waist-to-Hip Ratio (WHR)

The waist-to-hip ratio is the circumference of the waist (above the iliac crest) divided by the circumference of the hips (buttocks/hips measure) and has traditionally been used as a simple method for assessing body fat distribution and identifying individuals with higher and more detrimental amounts of abdominal fat.

Health risk increases as WHR increases, and the standards for risk vary with age and sex.

Copyright © 2014 American College of Sports Medicine

24

Circumferences (cont.)

Waist-to-Hip Ratio (cont.)

Health risk is very high for young men when WHR is >0.95 and for young women when WHR is >0.86.

For individuals aged 60–69 yr, the WHR cutoff values are >1.03 for men and >0.90 for women for the same high-risk classification as young adults.

Copyright © 2014 American College of Sports Medicine

25

Circumferences (cont.)

Waist Circumference

The waist circumference can be used alone as an indicator of health risk because abdominal obesity is the primary issue.

The Expert Panel on the Identification, Evaluation, and Treatment of Overweight and Obesity in Adults provides a classification of disease risk based on both BMI and waist circumference as shown in Table 4.1.

Copyright © 2014 American College of Sports Medicine

26

Circumferences (cont.)

Waist Circumference (cont.)

A newer risk stratification scheme for adults based on waist circumference has been proposed (see Table 4.3).

Evidence indicates that all currently available waist circumference measurement techniques are equally reliable and effective in identifying individuals at increased health risk.

Copyright © 2014 American College of Sports Medicine

27

Measurement of waist circumference immediately above the iliac crest, as proposed by National Institutes of Health guidelines, may be the preferable circumference method to assess health risk given the ease by which this anatomical landmark is identified (25).

29

Skinfold Measurements

Body composition determined from skinfold thickness measurements correlates well (r = 0.70–0.90) with body composition determined by hydrodensitometry.

The principle behind skinfold measurements is that the amount of subcutaneous fat is proportional to the total amount of body fat.

It is assumed that close to one-third of the total fat is located subcutaneously.

Copyright © 2014 American College of Sports Medicine

30

Skinfold Measurements (cont.)

The exact proportion of subcutaneous to total fat varies with sex, age, and race.

Regression equations used to convert sum of skinfolds to percent body fat should consider these variables for greatest accuracy.

31

Abdominal: Vertical fold; 2 cm to the right side of the umbilicus

Triceps: Vertical fold; on the posterior midline of the upper arm, halfway between the acromion and olecranon processes, with the arm held freely to the side of the body

Biceps: Vertical fold; on the anterior aspect of the arm over the belly of the biceps muscle, 1 cm above the level used to mark the triceps site

Chest/Pectoral: Diagonal fold; one-half the distance between the anterior axillary line and the nipple (men), or one-third of the distance between the anterior axillary line and the nipple (women)

Medial calf: Vertical fold; at the maximum circumference of the calf on the midline of its medial border

Midaxillary: Vertical fold; on the midaxillary line at the level of the xiphoid process of the sternum. An alternate method is a horizontal fold taken at the level of the xiphoid/sternal border in the midaxillary line

Subscapular: Diagonal fold (at a 45-degree angle); 1–2 cm below the inferior angle of the scapula

Suprailiac: Diagonal fold; in line with the natural angle of the iliac crest taken in the anterior axillary line immediately superior to the iliac crest

Thigh: Vertical fold; on the anterior midline of the thigh, midway between the proximal border of the patella and the inguinal crease (hip)

33

All measurements should be made on the right side of the body with the subject standing upright

Caliper should be placed directly on the skin surface, 1 cm away from the thumb and finger, perpendicular to the skinfold, and halfway between the crest and the base of the fold

Pinch should be maintained while reading the caliper

Wait 1–2 s (not longer) before reading caliper

Take duplicate measures at each site and retest if duplicate measurements are not within 1–2 mm

Rotate through measurement sites or allow time for skin to regain normal texture and thickness

Skinfold Measurements (cont.)

Factors that may contribute to measurement error within skinfold assessment include:

Poor technique

An inexperienced evaluator

An extremely obese or extremely lean subject

An improperly calibrated caliper (tension should be set at ~12 g · mm−2)

Copyright © 2014 American College of Sports Medicine

35

Although limited in the ability to provide highly precise estimates of percent body fat, anthropometric measurements (i.e., BMI, WHR, waist circumference, and skinfolds) provide valuable information on general health and risk stratification. As such, inclusion of these easily obtainable variables during a comprehensive health/fitness assessment is beneficial.

Anthropometric Measurements (second unnumbered box on p. 67)

Copyright © 2014 American College of Sports Medicine

Densitometry

Whole-body density using the ratio of body mass to body volume

Densitometry has been used as a reference or criterion standard for assessing body composition for many years.

The limiting factor in the measurement of body density is the accuracy of the body volume measurement because body mass is measured simply as body weight.

Copyright © 2014 American College of Sports Medicine

37

Densitometry (cont.)

Hydrodensitometry (underwater) weighing

Based on Archimedes’ principle:

When a body is immersed in water, it is buoyed by a counterforce equal to the weight of the water displaced.

Bone and muscle tissue are denser than water, whereas fat tissue is less dense. Therefore, an individual with more fat-free mass (FFM) for the same total body mass weighs more in water and has a higher body density and lower percentage of body fat.

Copyright © 2014 American College of Sports Medicine

38

Plethysmography

Measured by air rather than water displacement

Uses a dual-chamber plethysmograph that measures body volume by changes in pressure in a closed chamber

This technology is now well established and generally reduces the anxiety associated with the technique of hydrodensitometry

Copyright © 2014 American College of Sports Medicine

39

Other Techniques

Reliable and accurate body composition assessment techniques include dual-energy X-ray absorptiometry (DEXA) and total body electrical conductivity (TOBEC), but these techniques have limited applicability in routine health/fitness testing because of cost and the need for highly trained personnel.

Copyright © 2014 American College of Sports Medicine

40

Other Techniques (cont.)

Bioelectrical impedance analysis (BIA) and near-infrared interactance are used as assessment techniques in routine health/fitness testing. Generally, the accuracy of BIA is similar to skinfolds, as long as stringent protocol adherence (e.g., assurance of normal hydration status) is followed, and the equations programmed into the analyzer are valid and accurate for the populations being tested.

Copyright © 2014 American College of Sports Medicine

Other Techniques (cont.)

The ability of BIA to provide an accurate assessment of percent body fat in obese individuals may be limited secondary to differences in body water distribution compared to those who are in the normal weight range. Near-infrared interactance requires additional research to substantiate the validity and accuracy for body composition assessment.

45

Body Composition Norms (cont.)

A consensus opinion for an exact percent body fat value associated with optimal health risk has yet to be defined.

A range of 10%–22% and 20%–32% for men and women, respectively, has long been viewed as satisfactory for health.

More recent data support this range although age and race, in addition to sex, impact what may be construed as a healthy percent body fat.

Copyright © 2014 American College of Sports Medicine

46

Cardiorespiratory Fitness

Low levels of CR fitness have been associated with a markedly increased risk of premature death from all causes and specifically from cardiovascular disease

Increases in CR fitness are associated with a reduction in death from all causes.

High levels of CR fitness are associated with higher levels of habitual physical activity, which in turn are associated with many health benefits.

The assessment of CR fitness is an important part of a primary or secondary prevention and rehabilitative programs.

47

The Concept of Maximal Oxygen Uptake

Estimates of VO2max from the HR response to submaximal exercise tests are based on these assumptions:

A steady state HR is obtained for each exercise work rate.

A linear relationship exists between HR and work rate.

The difference between actual and predicted maximal HR is minimal.

.

.

Copyright © 2014 American College of Sports Medicine

48

The Concept of Maximal Oxygen Uptake (cont.)

Mechanical efficiency (i.e., VO2 at a given work rate) is the same for everyone.

The subject is not on medications that alter HR, using high quantities of caffeine, under large amounts of stress, ill, or in a high temperature environment, all of which may alter HR.

Modes of Testing (cont.) Submaximal Exercise Tests

Treadmill Tests

The same endpoint (70% HRR or 85% of age-predicted maximal HR) is used.

The stages of the test should be 3 min or longer to ensure a steady state HR response at each stage.

The HR values are extrapolated to age-predicted maximal HR.

55

Modes of Testing (cont.) Submaximal Exercise Tests

Treadmill Tests (cont.)

VO2max is estimated (see Chapter 7) from the highest speed and/or grade that would have been achieved if the individual had worked to maximum.

Most common treadmill protocols (see Chapter 5) can be used, but the duration of each stage should be at least 3 min.

Cardiorespiratory Test Sequence and Measures

A minimum of HR, BP, and subjective symptoms (RPE, dyspnea, and angina) should be measured during exercise tests.

After the initial screening process, selected baseline measurements should be obtained prior to the start of the exercise test.

Copyright © 2014 American College of Sports Medicine

58

Cardiorespiratory Test Sequence and Measures (cont.)

Heart Rate (HR)

HR can be determined using several techniques including radial pulse palpation, auscultation with a stethoscope, or the use of HR monitors.

The pulse palpation technique involves “feeling” the pulse by placing the second and third fingers (index and middle fingers) most typically over the radial artery.

For the auscultation method, the bell of the stethoscope should be placed to the left of the sternum just above the level of the nipple.

Copyright © 2014 American College of Sports Medicine

59

Cardiorespiratory Test Sequence and Measures (cont.)

Blood Pressure (BP)

BP should be measured at heart level with the subject’s arm relaxed and not grasping a handrail (treadmill) or handlebar (cycle ergometer).

Systolic (SBP) and diastolic (DBP) BP measurements can be used as indicators for stopping an exercise test.

Copyright © 2014 American College of Sports Medicine

60

Cardiorespiratory Test Sequence and Measures (cont.)

Rating of Perceived Exertion (RPE)

RPE can be a valuable indicator for monitoring an individual’s exercise tolerance.

Ratings can be influenced by psychological factors, mood states, environmental conditions, exercise modes, and age reducing its utility.

Currently, two RPE scales are widely used: (a) the original Borg or category scale, which rates exercise intensity from 6 to 20 (see Table 4.7); and (b) the category-ratio scale of 0–10. Both RPE scales are appropriate subjective tools.

Copyright © 2014 American College of Sports Medicine

61

Onset of angina or angina-like symptoms

Drop in SBP of ≥10 mm Hg with an increase in work rate or if SBP decreases below the value obtained in the same position prior to testing

Excessive rise in BP: systolic pressure >250 mm Hg and/or diastolic pressure >115 mm Hg

Shortness of breath, wheezing, leg cramps, or claudication

Signs of poor perfusion: light-headedness, confusion, ataxia, pallor, cyanosis, nausea, or cold and clammy skin

Failure of HR to increase with increased exercise intensity

Completed reports must be submitted by each individual of each group by week #4 Wednesday 9/24/14 by 9pm. Laboratory Report 1 – Health Assessment Purpose: To describe what this lab will accomplish. For this section begin by providing a brief introduction paragraph with citations and references in AMA format. Next, state the purpose of the lab which is to perform a Health Assessment of the individual assigned to you from the Lab Patients Fall 2014 data set. Each data set will include information such as patient’s goals, personal and family history, medications, gender, height, weight, anthropometric data, resting physiological data, and lipid profile. This lab will also include calculated data listed below. Note: There is no exercise testing data in lab report 1 but will be available for subsequent labs. Methods: Describe how the measurements and data presented in the results are obtained. Patient information is provided by interview. All other tests should be briefly explained such as height, weight, waist circumference, skin folds, resting physiological measurements and lipid profile. In addition present a brief explanation with formulas as necessary for determining calculated data: BMI, percent body fat, estimated maximum HR and risk classification (Figure 2.3 in ACSM). Do not present actual values/ratings (Results) or interpret the values (Discussion) in Methods. Results: Present patient Health information in Table format. Title the table: Table 1 Health Assessment. The table will have three columns: Topic, Value, and Rating. Some items such as history/age/gender, etc. will have no rating (-) while other values such as waist circumference, body fat, cholesterol, etc will have a rating for each item as appropriate. Include in this table calculated data which must include: risk classification, BMI, percent body fat, and age estimated max HR. The Risk Classification (Figure 2.3 ACSM) and Health Assessment values can be found in the ACSM (and EP) texts. Reference the Rating using AMA format. As an example, age estimated maximal heart rate equations can be found in Table 7.2. The value is cited with the superscript 1(p168) where 1 is the citation for the ACSM book and p168 is the location in the ACSM book. Tables that continue past one page must be relabeled with headings like Table 1 Health Assessment continued with new column headings (Topic, Value, and Rating). Discussion: Describe the overall health of the individual assigned to you using examples from the results. Provide support for your statements giving examples from the raw patient data set or calculated data with comparison to ratings. Avoid generalizations like “he is way out of shape” when you could say his “BMI of 28 kg/m2 indicates that he is overweight”, “results are shocking for this patient’s life-threatening condition” when you could say “she is at a higher risk for CVD given her high triglyceride levels”. Remember to cite and reference properly any statement you may make about your patient’s health assessment. As a health care provider this is your initial encounter where you examine the goals, history and base line health assessment data that this individual presents to you before you conduct any further exercise testing (Lab 2) or assign an exercise prescription (Final Lab). Although diet is recognized as important it is not the focus of this course so avoid any dietary recommendations. References: Cite and reference all resources you use to complete this lab report using AMA format. A good lab report cites and references more than just the assigned texts. Laboratory Report Format This is a GROUP report. Everyone in the group must submit the same lab report so collaboration is important as only one grade will be assigned to your entire group. Your grade is not the quantity but the quality of information.
