|
BLOOD FLOW |
Redistribution of blood flow away form internal organs and uterus toward working muscles CONCERNS Reduced oxygen and nutrient availability to fetus Stimulation of uterine contractions and preterm labour Increased stroke volume + cardiac output Coupled with increased blood volume + reduced systemic vascular resistance Offsets the effects of vascular shunting |
|
|
RESPIRATORY RATE |
Adapts to mild exercise Does not increase proportionately with moderate and severe exercise Maximum exercise capacity at a lower work level than nonpregnant woman |
|
|
HEMATOCRIT LEVEL |
Lowered during pregnancy Rises into 10 percent within 15 min of vigorous exercise Continues for upto 4 weeks postpartum Cardiac reserve is reduced in exercise |
|
|
INFERIOR VENA CAVA COMPRESSION |
By the uterus After 4h month of pregnancy Relative obstruction of venous return Decreased cardiac output Orthostatic hypotension Most often in supine position |
|
|
ENERGY NEEDS |
Hypoglycemia occurs more readily in pregnancy Ensure adequate carbohydrate intake 500 additional caloric intake per day for exercising woman 300 additional caloric intake per day for sedentary woman |
|
|
CORE TEMPERATURE |
Increased core temperature due to Vigorous physical activity Dehydration Relation between elevated core temp and neural tube defects in fetus Women with high physical fitness-> more efficient in regulating core temperature-> reduced core temp-> reduced thermal stress on fetus |
|
|
UTERINE CONTRACTIONS |
Increased norepinephrine and epinephrine levels with exercise NE-> increases strength and frequency of uterine contractions Risk of premature labour |
