PP 2: Preliminary Screening and Risk Classification
What are the ACSM Preparticipation Screening Algorithm Components
ACSM Preparticipation Screening Algorithm Components • Classifying individuals who do / do not currently participate in regular exercise • ID individuals with known CV, metabolic, or renal diseases or those with s/s (signs and symptoms) suggestive of cardiac, peripheral vascular, or cerebrovascular disease, Types 1 and 2 diabetes mellitus and renal disease • ID desired exercise intensity
CVD risk factors
Age, family history, smoking, sedentary, obesity, hypertension, dyslipidemia, prediabetes
Position of PT when heart rate is taken should be...

How long should we count to measure HR
15-60 secs
Self-Guided Methods
- Initiated and guided by individuals - Little or no supervision or input from exercise or health professional May complete of their own accord "previously inactive men over 40 yr and women over 50 yr, and people at high risk for CVD should first consult a physician before embarking on a program of vigorous physical activity to which they are not accustomed"- Surgeon General's Report on Physical Activity and Health - Others that may be incorporated Routine paperwork Entry procedures at health/fitness or clinical exercise program facilities PA promotional materials to the general public - May need to obtain medical clearance - Preparticipation health screening by self-reported medical history or health risk appraisal should be done all individuals wishing to initiate a physical activity program Easily accomplished by using the Par-Q+

CVD risk factor-based exercise preparticipation health screening may be - due to the high prevalence of risk factors and may lead to -
CVD risk factor-based exercise preparticipation health screening may be overly conservative due to the high prevalence of risk factors and may lead to excessive physician referrals, particularly in older adults • Exercise professionals are encouraged to complete a CVD risk factor assessment with their patients/clients as part of the preexercise evaluation

Designed to ID participants at risk for CV complications during / immediately after aerobicexercise
Why do we do preliminary screening and risk classification
Documented risks along with benefits ID individuals... Who should receive medical clearance before initiating an exercise program or ↑ the frequency, intensity, and/or volume of their current program With clinically significant disease/s who may benefit from participating in a medically supervised exercise program With medical conditions that may require exclusion from exercise programs until those conditions are abated or better controlled Recognize special needs of individuals that may affect exercise testing and programming
General Participant Instructions
Explicit instructions for participants before exercise testing ↑ test validity and data accuracy • Refrain from ingesting food, alcohol, caffeine or using tobacco products within 3 h of testing • Participants should be rested for the assessment, avoiding significant exertion or exercise on the day of the assessment • Clothing should permit freedom of movement and include walking or running shoes Women should bring a loose fitting, short-sleeved blouse that buttons down the front and should avoid restrictive undergarments.

Preparticipation health screening process
Preparticipation health screening before initiating PA or an exercise program is a two-stage process: 1.) The need for medical clearance before initiating / progressing exercise programming is determined using the updated / revised ACSM screening algorithm a) In the absence of professional assistance, interested individuals may use self-guided methods 2.) If indicated during screening, medical clearance should be sought from an appropriate health care provider a) The manner of clearance should be determined by the clinical judgement and discretion of the health care provider

True or False: The content and extent of consent forms may vary
True • Enough information must be present in the informed consent process to ensure that the participant knows and understands the purposes and risks associated with the test or exercise program in health/fitness or clinical settings
True or False: If the participant is a minor, a legal guardian or parent must sign the consent form
True • If the participant is a minor, a legal guardian or parent must sign the consent form
Informed Consent What should happen when the exercise test is for purposes other than diagnosis or Ex RX?
When the exercise test is for purposes other than diagnosis or Ex RX (i.e., for experimental purposes), this should be indicated during the consent process and reflected on the informed consent form, and applicable policies for the testing of human subjects must be implemented
Patient Privacy: Informed Consent
• All reasonable efforts must be made to protect the privacy of the patient's health information (e.g., medical history, test results) as described in the Health Insurance Portability and Accountability Act (HIPAA) of 1996
Informed Consent Because most consent forms include the statement "emergency procedures and equipment are available, what must that program provide?
• Because most consent forms include the statement "emergency procedures and equipment are available," the program must ensure available personnel are appropriately trained and authorized to carry out emergency procedures that use such equipment
Updated preparticipation process based on the outcomes of a scientific roundtable sponsored by ACSM in 2014
• The relative risk of a CV event is transiently ↑ during vigorous intensity exercise (compared to rest) but the absolute risk of an exercise-related acute cardiac event is low in healthy asymptomatic individuals • Among adults, the risk for activity associated SCD and AMI is highest among those with underlying CVD who perform unaccustomed vigorous PA.
Components of the Physical Exam
• Body weight; determination of body mass index, waist girth, and/or body composition • Apical pulse rate and rhythm • Resting blood pressure: seated, supine, and standing • Auscultation of the lungs with specific attention to uniformity of breath sounds in all areas (absence of rales, wheezes, and other breathing sounds) • Palpation of the cardiac apical impulse and point of maximal impulse • Auscultation of the heart with specific attention to murmurs, gallops, clicks, and rubs • Palpation and auscultation of carotid, abdominal, and femoral arteries • Evaluation of the abdomen for bowel sounds, masses, visceromegaly, and tenderness • Palpation and inspection of lower extremities for edema and presence of arterial pulses • Absence or presence of tendon xanthoma and skin xanthelasma • Follow-up examination related to orthopedic or other medical conditions that would limit exercise testing • Tests of neurologic function including reflexes and cognition (as indicated) • Inspection of the skin, especially of the lower extremities in known patients with diabetes mellitus
Risk Stratification for Patients in Cardiac Rehabilitation and Medical Fitness Facilities
• Exercise professionals working with patients with known CVD in exercise-based cardiac rehabilitation and medical fitness settings are advised to use more in-depth risk stratification procedures
Commonly used spirometry measurements
• Forced vital capacity (FVC) • Forced expiratory volume in one second (FEV1.0) • FEV1.0/FVC ratio* • Peak expiratory flow (PEF)
Participant Instructions If the evaluation is on an outpatient basis, participants should be made aware that...
• If the evaluation is on an outpatient basis, participants should be made aware that the exercise test may be fatiguing and that they may wish to have someone accompany them to the assessment to drive them home afterward.
Participant Instructions If the exercise test is for diagnostic purposes, it may be helpful for patients to...
• If the exercise test is for diagnostic purposes, it may be helpful for patients to discontinue prescribed cardiovascular medications, but only with physician approval. Currently prescribed antianginal agents alter the hemodynamic response to exercise and significantly reduce the sensitivity of ECG changes for ischemia. Patients taking intermediate- or high-dose β-blocking agents may be asked to taper their medication over a 2- to 4-d period to minimize hyperadrenergic withdrawal responses.
Participant Instructions If the test is for functional or Ex Rx purposes, patients should...
• If the test is for functional or Ex Rx purposes, patients should continue their medication regimenon their usual schedule so that the exercise responses will be consistent with responses expected during exercise training.
True or False: There is sufficient evidence to suggest that the presence of CVD risk factors without underlying disease confers substantial risk of adverse exercise-related CV events
