Brief summary
Maintaining a physically active lifestyle is associated with many health benefits, including lower risk of cardiovascular disease, diabetes, hypertension, some type of cancer, and depression . Pregnant, healthy women are recommended to do 30 minutes or more of light to moderate exercise a day, although most women in the Western world do not follow current recommendations and decrease their exercise level. Benefits of exercise during pregnancy are several, including a protective effect against the development of gestational diabetes mellitus, reduced pregnancy related low back pain, and risk of caesarean delivery. On the contrary, a recent review concludes that sedentary behaviors are associated with higher levels of C Reactive Protein and LDL Cholesterol, a larger newborn abdominal circumference, and macrosomia. Previous studies show that exercise during pregnancy is associated with improvements in psychological well-being among previously sedentary women. Only a few RCT's have studied resistance exercise during pregnancy. These studies have found reduced fatigue and reduced need of insulin among women with gestational diabetes mellitus who did resistance exercise, with no adverse effects on fetus or the pregnant woman. The aim of this study is to evaluate the efficacy of regular light -to-moderate resistance exercise among sedentary pregnant woman, with regard to fatigue, health related quality of life, pain location and intensity, body weight gain, blood pressure, and childbirth outcomes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in fatigue | Register at gestational week 22 and 34 | Visual Analogue Scale (VAS) 0-100 millimeters. It is a psychometric scale and measure self-reported fatigue from 0, no fatigue to 100, very great fatigue. The scale is a streight horizontal line. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain | Register at gestational week 22 and 34 | Visual Analogue Scale (VAS) 0-100 millimeters. It is a psychometric scale and measure the intensity of pain from 0, none pain to 100, extreme amount of pain. The scale is a streight horizontal line. |
| Change in Health Related Quality of Life | Register at gestational week 22 and 34 | Visual Analogue Scale (EQ-VAS). Mark health status on the day on a 20 centimeters vertical scale with end points of 0 and 100. There are notes at the both ends of the scale that the bottom rate (0) corresponds to the worst health you can imagine, and the highest rate (100) corresponds to the best health you can imagine. |
| Change in blood pressure | From perinatal records. Registered at gestational week 22 and 34 | Systolic and Diastolic |
| Change in weight gain | from perinatal records. Registered at gestational week 22 and 34 | kilogram |
| Gestational Diabetes Mellitus (GDM) | from perinatal records. Registered at gestational week 34 | Development of GDM |
| Change in anxiety / depression | Register at gestational week 22 and 34 | Visual Analogue Scale (VAS) 0-100 millimeters. It is a psychometric scale and measure self-reported anxiety/depression from 0, no anxiety/depression to 100, very great anxiety/depression. The scale is a streight horizontal line. |
| Birth weight | from perinatal records at birth (gestational week 40) | kilogram |
| Birth length | from perinatal records at birth (gestational week 40) | centimeters |
| Gestational age | From perinatal records at birth (gestational week 40) | days |
| Acute cesarean section | from perinatal records at birth (gestational week 40) | rate |
| Macrosomia | from perinatal records at birth (gestational week 40) | rate of birth with macrosomia |
| Change in exercise | Registered at gestational week 22 and 34 | Minutes a day. (Walks, light, moderate, vigorous intensity). |
