physiological adaptation and exercise benefits during pregnancy
Show Answers:

  1. What are the different systems that adapt during pregnancy?
    • endocrine
    • CV
    • respiratory
    • neuro-muscular
  2. What are some enlarged glands in pregnancy?
    adrenal, thyroid, parathyroid
  3. What hormones increase in pregnancy?
    • progesterone (if stop increasing at 10-12 wk, have miscarriage)
    • estrogen
  4. What's teh difference between glucose intolerance adn gestational diabetes?
    • intolerance = 1 abnormal level
    • diabetes = 2 abnormal levels
  5. What are some characteristics about gestational diabetes?
    • 33-50% probability in subsequent pregnancies
    • 50% increase in lifetime risk
    • increase risk of HTN
    • increase incidence in larger babies and obesity in the kids
  6. What are characteristics of preeclampsia?
    • increase in swelling
    • headaches
    • BP steadily rising
  7. What increases and decreases in the CV system with pregnancy?
    • increases: blood volume 40-50% by 32-34 wks, cardiac output (SV, and RHR by 15%)
    • decrease: maxHR, PV resistance, SBP decreases 10 mmHG, DBP decreases 15 mmHG
  8. What are some characteristics of supine hypotension syndrome?
    • supine symptoms of hypotension
    • will usually have to lay on L side because of compression of infereior vena cava
    • influenced by fetus size, maternal and fetal position
    • verbally screen in supine position
  9. What are some symptoms of supine hypotension syndrome?
    • Increase in HR
    • decrease in pulse pressure in spine
    • decrease SOA/nausea/vomitting
  10. What are some increases and decreases in the respiratory system due to pregnancy?
    • increases: tidal volume, respiratory rate, oxygen consumption
    • decreases: airway resistance; total, residual, and functional volume
  11. What are some changes to the neuromusculoskeletal system due to pregnancy?
    • muscle and joint pain
    • nerve entrapment syndromes
    • pregnancy related osteoporosis
    • increase risk in ankle sprains and knee injuries if continue exercising
  12. What are some benefits to the mother to continue exercising during pregnancy?
    • decrease BP, body fat, insulin needs, musculoskeletal pain
    • improved glucose tolerance
  13. What are some benefits to the fetus with exercises during pregnancy?
    • decreased birth weight, body fat and body mass
    • follow up studies show the kid weighs less, decrease sum of skin folds and less upper arm fat
    • decreases incidence of obestity/DM
  14. What are some absolute contraindications to exercise during pregnancy?
    • hemodynamically significant heart disease
    • restrictive lung disease
    • incomptetent cervix or cerclage
    • multiple gestation
    • persistent 2nd and 3rd trimester bleeding
    • placenta previa (after 26 wks)
    • premature labor
    • premature rupture of membrances
    • preeclampsia
  15. What predictors of pre term labor can make an exception to absolute contraindications?
    • fetal fibronectin: increases 7-10 days before labor so can check that with bloodwork
    • cervix: do vaginal exam and check cervix
  16. What are some relative contraindications to exercising while pregnant?
    • severe anemia
    • unevaluated maternal cardiac arrythmia
    • chronic bronchitis
    • poorly controlled type I DM
    • extreme morbid obesity
    • extremely underweight (BMI <12)
    • intrauterine growth retardation
    • poorly controlled HTN
    • hyperthyroidism
    • seizure disorder
    • orthopedic limitations
  17. What should teh exercise prescription be during pregnancy?
    • consult MD, screen for contraindications, PARmed-X for pregnancy
    • mode, frequency, and intensity based on pre-exercise level
    • educate pt on: heat dissipation, adequate fluid intake, when to reduce exercise (RPE), when to stop exercise
