Outcome Measures
Primary Outcomes (3)
Physical function measured with physical tests such as time to make a bed, get up and down off the floor and pick up scarves from the floor.
The intervention occurred from weeks 22 to 34 of pregnancy and the outcomes were measured the week before and after the intervention.
Change from week 21 to 35 of pregnancy
Quality of life measured using the Short Form 36 Healthy Survey.
The intervention occurred from weeks 22 to 34 of pregnancy and the outcomes were measured the week before and after the intervention.
Change from week 21 to 35 of pregnancy
Mood measured using the Profile of Mood States questionnaire.
The intervention occurred from weeks 22 to 34 of pregnancy and the outcomes were measured the week before and after the intervention.
Change from week 21 to 35 of pregnancy
Study Arms (3)
Resistance exercise
EXPERIMENTALResistance exercise involved 12 weeks of weight lifting exercise
Wait list
SHAM COMPARATORWait list participants were tested on the outcomes during their pregnancy and were eligible to participate in a post-partum supervised exercise program. The wait list participants formed a no treatment control group.
Pregnancy education
PLACEBO COMPARATORMaternity nurses taught six bimonthly pregnancy education classes (\~20 per class) which covered several topics including information about what to expect during normal labor and delivery, common interventions during delivery (medications, induction, Cesarean delivery), parenting skills needed for baby care, breastfeeding, baby and child cardiopulmonary resuscitation, typical child development and communicating with infants. No physical activity education was included in the curriculum. The pregnancy education participants formed an attention control group.
Interventions
Resistance exercise involved 12-weeks of strength training twice per week
Wait list participants were tested on the outcomes during their pregnancy and were eligible to participate in a post-partum supervised exercise program. The wait list participants formed a no treatment control group.
