General recommendations

Gradual cool down prevents post-exercise Hypotension

Management
Starting Exercise (non-athletes)

Exercise 30-60 minutes >3 times weekly (daily is best)
Choose aerobic Exercise that works large Muscle groups
Progressive Resistance Training
1. Limit intensity to 40-70% of One Repetition Maximum
2. Combine with aerobic activity
3. Use low resistance, but high repetition

Management
Banned Antihypertensives for athletes

Thiazide Diuretics (banned by USOC, NCAA)
Beta Blockers
1. Banned in shooting, archery, diving, ice skating

Medications
Preferred agents in athletes

ACE Inhibitor or Angiotensin Receptor Blocker (ARB)
1. Effects
  1. Slight decrease in Heart Rate
  2. Increases Stroke Volume
  3. Decreases Systemic Vascular Resistance
2. Advantages
  1. No effect on Energy Metabolism
  2. No Impairment of aerobic performance
3. Indications
  1. Good first-line Antihypertensive in athletes
Alpha Adrenergic Antagonist (e.g. Prazosin)
1. Effects
  1. Decreases Systemic Vascular Resistance
  2. No reflex increase in Heart Rate
  3. No reflex increase in Cardiac Output
2. Advantages
  1. No effect on Energy Metabolism
  2. No Impairment of aerobic performance
3. Disadvantages
  1. May be associated with CHF (avoid in age over 55)
Calcium Channel Blockers
1. Effects
  1. Decreased Systemic Vascular Resistance
  2. Only agent with significant venodilation
2. Disadvantages
  1. General
    1. Muscle Blood Flow may diminish
    2. Lactate threshold may be reached earlier
  2. Dihydropyridines (e.g. Amlodipine)
    1. Reflex Tachycardia
  3. Nondihydropyridines (e.g. Diltiazem)
    1. Slightly decreased maximum Heart Rate)
    2. Decreased contractility
3. Advantages
  1. No significant effect on Energy Metabolism
  2. No major Impairment of aerobic performance
4. Indications
  1. First line agent in black athletes
  2. First line agent in Exercise induced Hypertension

Medications
Less desirable agents in athletes

Cardioselective Beta Blockers
1. Effects
  1. Decreased Heart Rate
  2. Decreased heart contractility
  3. Increased Systemic Vascular Resistance
2. Disadvantages: Impacts aerobic performance
  1. Decreased Exercise tolerance
  2. Decreased maximum Heart Rate
  3. Banned in precision sports
  4. May exacerbate Asthma
3. Indications
  1. Comorbid condition (e.g. Coronary Artery Disease)
  2. Avoid in most athletes
4. Agents: Labetalol (combined Alpha-Beta Blocker)
  1. Preferred in athletes if Beta Blocker is needed
  2. Less Impairment of muscle Blood Flow
  3. Less Impairment of maximum oxygen uptake
Thiazide Diuretics
1. Effects
  1. Decreases plasma volume
  2. Decreases Cardiac Output
  3. Decreases Systemic Vascular Resistance
2. Indications
  1. Second-line agent if salt-sensitive
3. Disadvantages
  1. Dehydration risk
  2. Banned by USOC and NCAA

Special Circumstances
Exercise Induced Hypertension

Check Blood Pressure at peak Exercise
Exercise-induced Hypertension: Peak BP > 200/90
Best managed with Dihydropyridines (e.g. Amlodipine)
1. Only agents that result in significant venodilation
