“…This decrease comes from reductions in both movement intensity and the duration of physical activity (21,(23)(24)(25). Furthermore, in studies of well-nourished, normal-weight pregnant women, there is a decrease in the measured speed of SSW from early to late (26) and mid to late (27) gestation. Little objective data are available on the degree to which SSW speed or walking economy changes in obese women during pregnancy.…”

Background: Energy-conserving processes reported in undernourished women during pregnancy are a recognized strategy for providing the energy required to support fetal development. Women who are obese before conceiving arguably have sufficient fat stores to support the energy demands of pregnancy without the need to provoke energy-conserving mechanisms. Objective: We tested the hypothesis that obese women would show behavioral adaptation [ie, a decrease in self-selected walking (SSW) speed] but not metabolic compensation [ie, a decrease in resting metabolic rate (RMR) or the metabolic cost of walking] during gestation. Design: RMR, SSW speed, metabolic cost of walking, and anthropometric variables were measured in 23 women aged 31 6 4 y with a BMI (in kg/m 2 ) of 33.6 6 2.5 (mean 6 SD) at ;15 and 30 wk of gestation. RMR was also measured in 2 cohorts of nonpregnant control subjects matched for the age, weight, and height of the pregnant cohort at 15 (n = 23) and 30 (n = 23) wk. Results: Gestational weight gain varied widely (11.3 6 5.4 kg), and 52% of the women gained more weight than is recommended. RMR increased significantly by an average of 177 6 176 kcal/d (11 6 12%; P , 0.0001); however, the within-group variability was large. Both the metabolic cost of walking and SSW speed decreased significantly (P , 0.01). Whereas RMR increased in .80% of the cohort, the net oxygen cost of walking decreased in the same proportion of women. Conclusion: Although the increase in RMR was greater than that explained by weight gain, evidence of both behavioral and biological compensation in the metabolic cost of walking was observed in obese women during gestation. The trial is registered with the Australian Clinical Trials Registry as ACTRN012606000271505.Am J Clin Nutr 2011;94:819-30.

“…However, each method has its own strengths and limitations. The RT3 accelerometer is used to assess physical activity in children [10,11], adolescents [11], overweight adults [12], pregnant women [13], individuals with multiple sclerosis [14], and older adults with coronary heart disease [15]. Klassen et al report that the RT3 accelerometer can detect a significant difference between moderately active and active individuals with multiple sclerosis [14].…”

“…Although its reliability, validation, and application in measuring physical activeity in different population have been reported [10][11][12][13][14][15], the relationship between disease activity and energy expenditure measured by the RT3 accelerometer in SLE patients has not been previously established.…”

This study aimed to characterize energy expenditure patterns using the tri-axial accelerometer and to identify the association of energy expenditure with clinical parameters in patients with systemic lupus erythematosus (SLE). Estimates of energy expenditures represented by total activity calorie (TA), physical activity calorie (PA), total activity calorie per body weight (TABW), and physical activity calorie per body weight (PABW) of 49 female SLE patients were assessed using the RT3 tri-axial accelerometer (StayHealthy, Monrovia, CA) in a seven-day period. SLE patients in the highest body mass index (BMI) tertile showed significantly lower values of TABW compared to those in the lowest tertile, while SLE patients in the lowest TABW tertile showed significantly higher body weight, waist circumference, BMI, SLE disease activity index (SLEDAI), dosage of prednisone, and blood pressure. There was a high prevalence of metabolic syndrome and SLE patients with metabolic syndrome showed significantly lower TABW. In addition, both TABW and PABW significantly but negatively correlated with SLEDAI. In conclusion, the RT3 accelerometer is suitable for evaluating total and physical activity-related energy expenditure in patients with SLE. TABW measured by the tri-axial accelerometer is inversely related with body weight status and disease activity in SLE patients. This suggests that estimates of energy expenditure by the tri-axial accelerometer may be applied in the management of SLE.

“…Postpartum factors associated with inactivity included weight retention, working longer hours in the first trimester and reported lack of child care. Dinallo et al 35 used accelerometry to show that pregnant women slowed down their walking pace in a treadmill walking condition as pregnancy progressed. The authors observed that less than 12% of women in the study's free-living condition met recommended physical activity guidelines consistent with the findings of other investigations.…”

Does exercise have a role in the management of gestational diabetes mellitus?

Summary: Gestational diabetes mellitus (GDM) is associated with a marked increase in the long-term risk of type 2 diabetes and adverse pregnancy outcomes. Engaging in vigorous recreational physical activity prior to and during pregnancy significantly reduces the risk of developing GDM. In contrast, evidence of a therapeutic effect from participation in a structured exercise training regimen, although promising, is limited and requires further more substantial investigation. This paper briefly reviews the pathophysiology of GDM, the evidence related to physical activity participation and exercise regimen intervention on GDM, and the clinical considerations required for prescribing exercise.
