The principle behind the skinfold technique is that the amount of
subcutaneous fat is proportional to the total amount of body fat
Basic body composition can be expressed as the
relative percentage of body mass that is fat and fat-free tissue using a two-compartment model
High intensity statin therapy is generally recommended for those with 10-yr risk estimated to be ___% (high risk)
≥7.5%
Siri Equation
%Fat = [(495/body density) - 450] x 100
The information obtained from health-related physical fitness testing, in combination with the individual's medical and exercise history, is used for the following:
- *Collecting baseline data and 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* (Ex Rx) to address all health/ fitness components. - *Collecting follow-up data that allow evaluation of progress* following an Ex Rx and long-term monitoring as participants age. - *Motivating participants* by establishing reasonable and attainable health/ fitness goals
The following steps should be taken to ensure client safety and comfort before administering a health-related physical fitness test:
- *Perform the informed consent process* and allow time for the individual undergoing assessment to have all questions adequately addressed (see Figure 3.1). - *Perform exercise preparticipation health screening* (see Chapter 2). - *Complete a preexercise evaluation including a medical history and a cardiovascular disease (CVD) risk factor assessment *(see Chapter 3). A minimal recommendation is that individuals complete a self-guided questionnaire such as the Physical Activity Readiness Questionnaire + (PAR-Q +) (see Figure 2.1). Other more detailed medical history forms may also be used. - *Follow the list of preliminary testing instructions* for all clients located in Chapter 3 under "Participant Instructions" section. These instructions may be modified to meet specific needs and circumstances.

The ACSM-AHA Primary Physical Activity Recommendations
- All healthy adults aged 18-65 yr should participate in moderate intensity aerobic PA for a minimum of 30 min on 5d/wk OR vigorous intensity intensity aerobic activity for a minimum of 20 min on 3d/wk - Combinations of mod and vig intensity exercise can be performed to meet this recommendation - Moderate intensity aerobic exercise can be accumulated to total the 30 min minimum by performing bouts each lasting >10 min - Every adult should perform activities that maintain or increase muscular strength and endurance for a min of 2d/wk - Because of the dose-response relationship between PA & health, individuals who wish to further improve their fitness + other benefits may exceed the minimum rec. of PA for more benefits
Pulmonary function testing with a spirometry is recommended for
- All smokers > 45 yr old - In any individual presenting with dyspnea (i.e., shortness of breath), - Chronic cough - Wheezing - Excessive mucus production
Preparticipation Screening algorithm
- Apparently healthy participants who do not currently exercise and have no history or signs or symptoms of CV, metabolic, or renal disease can immediately, and without medical clearance, initiate an exercise program at light-to-moderate intensity. If desired, progression beyond moderate intensity should follow the principles of Ex Rx covered in Chapter 6. - Participants who do not currently exercise and have (a) known CV, metabolic, or renal disease and (b) are asymptomatic should obtain medical clearance before initiating a structured exercise program of any intensity. Following medical clearance, the individual may embark on light-to-moderate intensity exercise and progress as tolerated following ACSM Guidelines. - Symptomatic participants who do not currently exercise should seek medical clearance regardless of disease status. If signs or symptoms are present with activities of daily living, medical clearance may be urgent. Following medical clearance, the individual may embark on light-to-moderate intensity exercise and progress as tolerated following ACSM Guidelines (see Chapter 6). - Participants who already exercise regularly and have no history or signs or symptoms of CV, metabolic, or renal disease may continue with their current exercise volume/ intensity or progress as appropriate without medical clearance. - Participants who already exercise regularly; have a known history of CV, metabolic, or renal disease; but have no current signs or symptoms (i.e., are clinically "stable") may continue with moderate intensity exercise without medical clearance. However, if these individuals desire to progress to vigorous intensity aerobic exercise, medical clearance is recommended. - Participants who already exercise regularly but experience signs or symptoms suggestive of CV, metabolic, or renal disease (regardless of disease status) should discontinue exercise and obtain medical clearance before continuing exercise at any intensity.
Muscular strength and endurance are health-related fitness components that may improve or maintain the following important health-related fitness characteristics
- Bone mass, which is related to osteoporosis - Muscle mass, which is related to sarcopenia - Glucose tolerance, which is pertinent in both the prediabetic and diabetic state - Musculotendinous integrity, which is related to a lower risk of injury including low back pain - The ability to carry out the activities of daily living, which is related to perceived quality of life and self-efficacy among other indicators of mental health - FFM and resting metabolic rate, which are related to weight management

- Determining current PA levels - Identifying signs and symptoms of underlying CV, metabolic, and renal disease - Identifying individuals with diagnosed CV and metabolic disease - Using signs and symptoms, disease history, current exercise participation, and desired exercise intensity to guide recommendations for preparticipation medical clearance
The following should be accomplished before the client/ patient arrives at the test site:
- Ensure consent and screening forms, data recording sheets, and any related testing documents are available in the client's file and available for the test's administration. - *Calibrate all equipment* (e.g., cycle ergometer, treadmill, sphygmomanometer) *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. Skinfold calipers should be regularly checked for accuracy and sent to the manufacturer for calibration when needed. - *Ensure a room temperature between 68 ° F and 72 ° F* (20 ° C and 22 ° C) and humidity of less than 60% with adequate airflow
Factors that can alter submax HR response
- Environmental - Dietary - Behavioral
Two important conclusions from the Physical Activity Guidelines Advisory Committee Report
- Important health benefits can be obtained by performing a moderate amount of PA on most, if not all days of the week - Additional health benefits result from greater amounts of PA. Individuals who maintain a regular program of PA that is longer in duration, of greater intensity, or both are likely to derive greater benefit than those who engage in lesser amounts.
A comprehensive health/ fitness assessment includes the following:
- Informed consent and exercise preparticipation health screening - Preexercise evaluation - Resting measurements - Circumference measurements and body composition analysis - Measurement of CRF - Measurement of muscular fitness - Measurement of flexibility.

Stop test when reaches 70% HR from 85% predicted, fails protocol, symptoms, asks to stop, emergency 10. Physiologic observations monitored for at least 5 min. Continue low level exercise until HR & BP stabel
Preparticipation health screening before initiating PA or an exercise program for gen. pop is a two-stage process:
1. The need for medical clearance before initiating or progressing exercise programming is determined using the updated and revised ACSM screening algorithm (see Figure 2.2) and the help of a qualified exercise or health care professional. In the absence of professional assistance, interested individuals may use self-guided methods (discussed later). 2. If indicated during screening (see Figure 2.2), medical clearance should be sought from an appropriate health care provider (e.g., primary care or internal medicine physician, cardiologist). The manner of clearance should be determined by the clinical judgment and discretion of the health care provider.
Two consecutive HR measurements between ___ & ___ should be obtained to predict VO2max
