3. Exercise Intolerance/ Adaptations/Screening

What are some Heart Rate Alerts?

• Failure of HR to rise proportionally to intensity

• Failure of SBP to rise during exercise

• Decrease in SBP 20mmHG

• Increase in DBP >15mmHG

What are some Exercise Intolerance S/Sx?

• Angina - chest pain or discomfort that can feel like squeezing, pressure, heaviness, or tightness

• Unusual or Severe Shortness of Breath

• Abnormal Diaphoresis - Excessive Sweating

• Pallor, Cyanosis, Cold & Clammy Skin

• Central Nervous System Symptoms - Example: Ataxia

• Leg Cramps or Intermittent Claudicating - muscle pain that happens when you're active

• Physical or Verbal Signs of Severe Fatigue or SOB

What happens to the Weight & Volume of Heart as of a result of improved Aerobic Training?

• Increased thickness of Wall

• Increased chamber size

• Heart will pump / beat

What happens to the Heart Rate as of a result of improved Aerobic Training?

• Decreased Resting HR

• Decreased Rate at Submaximal Exercise Levels

• Max HR does not change

What happens to the Blood Volume as of a result of improved Aerobic Training?

• Increase in plasma volume

  • Hormones: Antidiuretic & Aldosterone

    • Promote Water Retention

• Small increase in red blood cells

• Increase profusion of oxygen to cells

What happens to Resting BP as of a result of improved Aerobic Training?

• Hypertensive / Borderline Hypertensive

• Decrease both SBP & DBP by 12mmHG

What Respiratory Adaptations happen as a result of improved Aerobic Training?

• Tidal Volume Increased

• RR is lower at rest & submax levels

• RR is increased with maximal levels

• Increased pulmonary ventilation

What happens as a result of improved Aerobic Training when you Max Exercise?

• Increase blood to lungs

• Increase Ventilation

• More Alveoli working in concert

What is Coronary Arterial Disease?

heart disease that occurs when plaque builds up in the arteries that supply oxygen to the heart, making them too narrow to properly function.

List of Coronary Risk Factors

• Male Family History of CAD <55 years

• Female Family History of CAD <65 years

• Current or recent smoker (quit in last 6 months)

• Hypertension (> 140 / > 90)

• Dyslipidemia (LDL > 130mg/dL)

• HDL <40mg/dL

• Total cholesterol > 200mg/dL

• Impaired Fasting Glucose > 120mg/dL

• Obesity (BMI > 30) or Sedentary Lifestyle
