indication for aerobic exercise

- reduced cardio respiratory endurance
- Primary and Secondary prevention of cardiovascular disease


precautions/contraindication for aerobic exercise

-Appropriate screening or health appraisal should be perfomed prior to beginning exercise training to identify known disease, risk factors for coronary artery disease and other factors that wil optimize adherence minimize risk and maximize benefits
- avoid valsalva maneuver


overload principle

-to improve its function, a tissue or organ must be exposed to a stress or load greater than that which is normally encounters


principle of specificity

- states that teh long-term adaptation to the metabolic and physiologic systems derived from exercise are specific to the exercises perfomed and teh muscles involved


target heart rate

- is established from lower and upper heart rate limits calculated using differnet percentage training intensities depending on the individual's age, fitness level, health status, and goals


calculate lower THR
-via percent of max HR
-via Karvonen formula or HRR

- Lower THR = HRmax x55%

- lower THR= [(HRmax- HRrest) x40%] +HR rest


calculate Upper THR
-via percent of max HR
-via Karvonen formula or HRR

- Upper THR= HR max x 90%

-Upper THR= [(HR max-HRrest) x 85%] +HRrest


Duration of aerobic exercise

- duration is dependent on the intensity of the activity
-20-60 minutes of cont or intermittent activity (minimum of 10min bouts accumulated throughout the day)
-lower intensity activity should be performed over a longer period of time
-higher intensity activity should be performed for 20 min or longer
- mod intensity activity of longer duration is recommended for adults not training for athletic competition due to the potential hazards and adherence associated with high-intensity activity


normal cariorespiratory Response to Acute Aerobic exercise

- increased oxygen consumption due to incr cardiac output,incr blood flow, and oxygen utilization in the exercising skeletal muscles
- linear incr in SBP with increasing workload
no change or moderate decrease in DBP
-incr RR and Tidal Volume


Chronic adaptations to aerobic Exercise

- VO2 max: incr at maximal exercise
-HR: no change or decrease at maximal exercise; decr at submaximal exercise
-Arteriovenous oxygen differnece: incr at maximal exercise; no change at submaximal exercise
- SBP and DBP: no change or slight incr at max exercise; no change or slight decr at submaximal exercise
-blood lactate: incr at max exercise; decreased at submaximal exercise
