ACSM Risk Classification Calculator

Exercise Participation

Performing planned, structured physical activity at least 30 minutes on at least 3 days a week for at least the last 3 months.

No Exercise

Light Intensity Exercise

  • 30% to 40% HRR or V˙ O2R, 2 to G3 METs, 9–11 RPE
  • an intensity that causes slight increases in HR and breathing

Moderate Intensity Exercise

  • intensity comfortably sustainable for about 45 minutes
  • approximately 3-6 METs: equivalent to walking 3-4 mph (4.8-6.5 kmph)
  • 40%-60% of maximal oxygen uptake

Vigorous Intensity Exercise

  • produces substantial cardiorespiratory challenge
  • greater than 6 METs: running or walking faster than 4 mph (>6.5 kmph)
  • greater than 60% of maximal oxygen uptake

Diagnosed Disease

Cardiovascular Disease

  • Cardiac, peripheral vascular, or cerebrovascular disease

Pulmonary disease

  • Chronic obstructive pulmonary disease, asthma, interstitial lung disease, or cystic fibrosis

Metabolic disease

  • Diabetes mellitus (type I or II), thyroid disorders, renal or liver disease

Renal disease

Major Symptoms or Signs Suggestive of Cardiovascular and Pulmonary Disease

The following signs and symptoms must be interpreted within the clinical context in which they appear since they are not all specific for metabolic, pulmonary, or cardiovascular disease

Pain or discomfort in the chest, neck, jaw, arms, or other areas that may be due to myocardial ischemia (lack of adequate circulation)

Shortness of breath at rest, during daily activities, or with mild exertion

Dizziness or syncope (fainting)

Orthopnea (breathing discomfort when not in an upright position) or paroxysmal nocturnal dyspnea (interrupted breathing at night)

Ankle edema (swelling)

Palpitations (abnormal rapid beating of the heart) or tachycardia (rapid heart beat)

Intermittent claudication (cramping pain and weakness in legs, especially calves, during walking due to inadequate blood supply to muscles)

Known heart murmur (atypical heart sound indicating a structural or functional abnormality)

Unusual or unexplained fatigue
