Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Type of birth. | Type of delivery such as vaginal, cesarean section or instrumental birth would be recorded from maternal records after birth. | 2 weeks postpartum. | |
Other | Type of analgesia used during labour | Type of analgesia (pharmacological or non-pharmacological) used during labour would be recorded from maternal records after birth. | 2 weeks postpartum. | |
Other | New born's Apgar score | Apgar score is a scale that measures health in the new born. This scale focuses on five parameters (skin colour, heart rate, reflexes and responsivness, muscular tone, and breathing rate), each of them rated from 0 to 2. This test is performed at the first and fifth minute of new born's life. Scores above 7 are consider normal, scores below 7 indicates that the new born needs medical attention. Scores from both tests (1min and 5min) would be recorded from maternal records after birth. | 2 weeks postpartum. | |
Other | Changes in maternal hand grip strength during pregnancy. | Maternal hand grip strength would be measured using a hand grip dynamometer. This test would be performed during the second and third trimester of pregnancy. | 18 and 36 weeks of pregnancy. | |
Other | Maternal hand grip strength during postpartum. | Maternal hand grip strength would be measured using a hand grip dynamometer. This test would be performed during the postpartum period. | 12 weeks postpartum. | |
Other | Changes in maternal upper body range of motion during pregnancy. | Maternal upper body flexibility during second and third trimester would be measured using the back scratch test. This test measures how close the hands can be brought together behind the back. | 18 and 36 weeks of pregnancy. | |
Other | Maternal upper body range of motion during postpartum. | Maternal upper body flexibility during the early postpartum would be measured using the back scratch test. This test measures how close the hands can be brought together behind the back. | 12 weeks postpartum. | |
Primary | Changes in maternal cardiac output during and after pregnancy. | Maternal cardiac output at rest, during exercise and after exercise measured in L/min would be recorded from study participants to analyse and compare potential changes inter and intra group. | 18 and 36 weeks of gestation, 12 weeks postpartum. | |
Primary | Changes in maternal heart rate during and after pregnancy. | Maternal heart rate at rest and after exercise would be recorded in beats per minute to be analysed and compared inter and intra group. | 18 and 36 weeks of gestation, 12 weeks postpartum. | |
Primary | Changes in maternal heart rate variability during and after pregnancy | Maternal heart rate variability at rest, during and after exercise would be measured by r to r interval. It would be recorded and analysed to compare inter and intra group changes. | 18 and 36 weeks of gestation, 12 weeks postpartum. | |
Primary | Foetal heart rate | Foetal heart rate baseline would be measured at rest, during and after exercise. It would be analysed and compared in between groups. | 36 weeks pregnancy | |
Secondary | Changes in active pregnant women energy expenditure | Data obtained from accelerometer devices worn by exercise group participants. | 18 and 36 weeks pregnancy. | |
Secondary | Changes in sedentary pregnant women energy expenditure | Data obtained from accelerometer devices worn by control group participants. | 18 and 36 weeks pregnancy. | |
Secondary | Energy expenditure during the early postpartum period. | Data obtained from accelerometer devices worn by all participants in the study. | 12 weeks postpartum. | |
Secondary | Gestational weight gain. | Weight gain during pregnancy measured in kilograms would be recorded to be compared in between study groups. | 36 weeks pregnancy. | |
Secondary | Changes in maternal body fat percentage during pregnancy. | Body fat percentage calculated from skinfold-thickness measures would be compared in between study groups. | 18 and 36 weeks pregnancy. | |
Secondary | Birth weight | Birth weight from new borns recorded in kilograms would be collected from maternal records. It would be analysed and compared between groups. | Second week after birth. | |
Secondary | Results from Qol-Grav questionnaire during second and third trimester of pregnancy. | The Qol-Grav questionnaire is a validated questionnaire used to measure quality of life in pregnant women. This questionnaire would be filled in by study participants and analysed to record their quality of life during the current pregnancy. Scores derived from the questionnaire would be analysed and compared between groups.
The following total score scale is presented: 9-18: Excellent quality of life. 19-27: Very good quality of life. 28-36: Good quality of life. 37-45: Not very good quality of life. |
18 and 36 weeks pregnancy. | |
Secondary | Pre-pregnancy physical activity levels recorded by the modified physical activity questionnaire. | Participants' pre-pregnancy physical activity levels would be registered using the modified physical activity questionnaire. This questionnaire records information about activities performed for the three months before pregnancy. Intensity of the activity would be recorded using three different levels of intensity (low, moderate and vigorous). Average time spent in each activity would be recorded in minutes. These values would be used to measure time and intensity spent in physical activity before pregnancy, and would be compared between groups. | 12 weeks pregnancy. | |
Secondary | Pregnancy physical activity levels during first trimester recorded by the modified physical activity questionnaire. | Participants' physical activity levels during the first trimester of pregnancy would be registered using the modified physical activity questionnaire. This questionnaire records information about activities performed during the first three months of pregnancy. Intensity of the activity would be recorded using three different levels of intensity (low, moderate and vigorous). Average time spent in each activity would be recorded in minutes. These values would be used to measure time and intensity spent in physical activity during pregnancy, and would be compared between groups. | 12 weeks pregnancy. | |
Secondary | Pregnancy physical activity levels during second and third trimester recorded by the modified physical activity questionnaire. | Participants' physical activity levels during the second and third trimester of pregnancy would be registered using the modified physical activity questionnaire. This questionnaire records information about activities performed during the second an third trimesters of pregnancy. Intensity of the activity would be recorded using three different levels of intensity (low, moderate and vigorous). Average time spent in each activity would be recorded in minutes. These values would be used to measure time and intensity spent in physical activity during pregnancy, and would be compared between groups. | 36 weeks pregnancy. | |
Secondary | Changes in quality of sleep during pregnancy. | Two questionnaires would be used to measure participants' quality of sleep during their pregnancy. These questionnaires are the Pittsburgh Sleep Quality Index and the Insomnia Severity Index. | 18 and 36 weeks of pregnancy. | |
Secondary | Quality of sleep during postpartum. | Two questionnaires would be used to measure participants' quality of sleep during the postpartum period. These questionnaires are the Pittsburgh Sleep Quality Index and the Insomnia Severity Index. | 12 weeks postpartum. | |
Secondary | Sleep patterns in the three months old infant | The Brief Screening Questionnaire for Infant Sleep Problems would be used to register sleep patterns in the three months old infants born from study participants. Items recorded in the questionnaire are the following: sleep arrangement, time spent sleeping during the day and night, number of wakings per night, mode of falling asleep, time spent in wakefulness and normal time of falling asleep at night. | 12 weeks postpartum. |
