      abstract = {Background: Prenatal exercise improves birth outcomes, but  research into
exercise dose–response effects is  limited.
Methods: This study is a retrospective, secondary  analysis of pooled data from
three blinded, prospective,  randomized controlled trials. Prenatal exercise frequency,  intensity, type, time, and volume (FITT-V) were assessed in  supervised
sessions throughout pregnancy. Gestational age  (GA), neonatal resting heart
rate (rHR), morphometrics  (body circumferences, weight-to-length and ponderal index)  Apgar and reflex scores, and placental measures were  obtained at
birth. Stepwise regressions and Pearson  correlations determined associations
between FITT-V and  birth outcomes.
Results: Prenatal exercise frequency  reduces ponderal index (R2 = 0.15,
F = 2.76, p = .05) and  increased total number of reflexes present at birth
(R2 =  0.24, F = 7.89, p < .001), while exercise intensity was  related to greater
gestational age and birth length (R2 =  0.08, F = 3.14; R2 = 0.12, F = 3.86,
respectively; both p =  .04); exercise weekly volume was associated with  shorter
hospital stay (R2 = 0.24, F = 4.73, p = .01).  Furthermore, exercise type was
associated with placenta  size (R2 = 0.47, F = 3.51, p = .01).
Conclusions: Prenatal  exercise is positively related to birth and placental  outcomes in a dose-dependent manner},
