Influence of a Concurrent Exercise Training Program on Health-Related Quality of Life During Advanced Pregnancy: The GESTAFIT Project.

BACKGROUND: Health-related quality of life (HRQoL) may be altered during pregnancy due to pregnancy-related changes in all domains of women's health. HYPOTHESIS: A supervised concurrent exercise-training program from the 17th gestational week until birth positively influences HRQoL. STUDY DESIGN: Randomized controlled trial. LEVEL OF EVIDENCE: Level 1. METHODS: Eighty-six pregnant women (age, 33.1 ± 4.6 years; prepregnancy body mass index, 23.5 kg/m2), divided into exercise (n = 41) and control (n = 45) groups, participated in this study (per-protocol basis). The exercise group followed a 60-min, 3 days/week, concurrent (aerobic + resistance) exercise training program. HRQoL was assessed with the 36-Item Short Form Health Survey (SF-36), where higher scores (0-100) indicate better HRQoL. RESULTS: After adjusting for potential confounders, the exercise group decreased 16.1 points less than the control group in the SF-36 physical functioning domain [between-group differences (B): 95% confidence interval (CI), 9.02 to 23.22; P < 0.01], and 4.5 points less in the SF-36 physical component summary than the control group (between-group differences (B): 95% CI, 0.65 to 8.28; P = 0.02). Intention-to-treat basis analyses depicted similar results, where the exercise group decreased 10.03 points less than the control group the in the SF-36 social functioning domain (between-group differences (B): 95% CI, 0.39 to 19.68; P = 0.04). CONCLUSION: A supervised concurrent exercise training program ameliorates HRQoL decreases along gestation. Although HRQoL decreased throughout pregnancy in both groups, this impact was less in the exercise group, especially in the SF-36 physical functioning, the SF-36 social functioning, and the SF-36 physical component summary. CLINICAL RELEVANCE: Healthcare providers may encourage pregnant women to exercise in this physiological stage for a better HRQoL throughout pregnancy.

Effects of a concurrent exercise training program on low back and sciatic pain and pain disability in late pregnancy.

OBJECTIVE: The aim of the present study was to explore the influence of a concurrent exercise (aerobic + resistance) training program, from the 17th gestational week (g.w.) until birth on low back and sciatic pain, and pain disability. A total of 93 pregnant women divided into exercise (n = 49) and control (n = 44) groups followed a 60-min, 3 days/week, concurrent exercise training. METHODS: Low back and sciatic pain were measured with a Visual Analogic Scale (VAS). The disability resulting from pain was assessed with the Oswestry Disability Index (ODI). Measures were performed at the 16th and 34th g.w. RESULTS: The exercise group increased 21.9 mm less the VAS low back (between-group differences (B): 95% CI: -33.6 to -10.2; p < 0.001) and 12.9 mm less the VAS sciatica score (between-group differences: 95% CI (B): -21.8 to -4.0; p = 0.005) than the control group. Regarding the ODI questionnaire, the exercise group increased 0.7, 0.5, and 0.7 less than the control group in pain while sleeping (between-group differences (B): 95% CI: -1.4 to -0.01; p = 0.025), pain while lifting weight (between-group differences (B): 95% CI: -0.9 to -0.01; p = 0.016), and limitations of the social life due to pain (between-group differences(B): 95% CI: -1.3 to -0.06; p = 0.032). Furthermore, the exercise group suffered 6.9% less pain than the control group in the ODI total score (between-group differences (B): 95% CI: -13.9 to 0.053; p = 0.052). CONCLUSION: This concurrent exercise training program adapted to pregnant women improved pain compared to controls.

A concurrent prenatal exercise program increases neonatal and placental weight and shortens labor: The GESTAFIT project.

OBJECTIVE: To explore the influence of a supervised concurrent exercise-training program during pregnancy on maternal and neonatal birth-related outcomes and type of birth. METHODS: One hundred and fifty-nine Caucasian pregnant women from the GESTAFIT project participated in this quasi-experimental study and were allocated into control [(n = 86), (age 33.1 ± 4.8 years old, BMI 24.8 ± 4.1 kg/m2 )] or exercise group [(n = 50) (age 33.1 ± 4.1 years old, BMI: 24.7 ± 4.1 kg/m2 )]. The exercise group followed a 60-min 3 days/week concurrent (aerobic and strength) training program from the 17th gestational week until birth. Maternal and neonatal birth-related outcomes (i.e., gestational age at birth, duration of labor, placental and neonatal weight and type of birth) were collected from obstetric medical records. Umbilical arterial and venous blood gas analysis were assessed after birth. RESULTS: The exercise group increased average duration of the first stage of labor [between-group differences (B): 80.8 min, 95% confidence interval (CI), 4.18, 157.31, p = 0.03] and decreased duration of the second stage of labor [between-group differences (B): 29.8 min, 95% CI: -55.5, -4.17, p = 0.02] compared to the control group. The exercise group showed greater placental [between-group differences (B): 53.3 g (95% CI: 9.99, 96.7, p = 0.01)] and neonatal [between-group differences (B): 161.8 g (95% CI: 9.81, 313.8, p = 0.033)] weight compared to the control group. No differences between groups were found regarding type of birth (p > 0.05). CONCLUSIONS: A concurrent and supervised physical exercise program during pregnancy is safe and could promote better maternal and neonatal birth-related outcomes. More studies are needed to clarify the mechanisms by which physical exercise increases neonatal and placenta weight.

Physical fitness and maternal body composition indices during pregnancy and postpartum: the GESTAFIT project.

We explored the association of physical fitness (PF) during pregnancy with maternal body composition indices along pregnancy and postpartum period. The study comprised 159 pregnant women (32.9 ± 4.7 years old). Assessments were carried out at the 16th and 34th gestational weeks (g.w.) and six weeks postpartum. Cardiorespiratory fitness (CRF), muscular strength (absolute and relative values) and flexibility were measured. Body composition indices were obtained by using dual-energy X-ray absorptiometry at postpartum. The results, after adjusting for potential covariates at the 16th g.w., indicated that greater CRF was associated with lower postpartum indices total fat mass, android and gynoid fat mass (all, p < 0.05). Greater absolute upper-body muscular strength was associated with greater pre-pregnancy body mass index (BMI), gestational weight gain (GWG); and postpartum indices body weight, BMI, lean mass, fat free mass, fat mass, gynoid fat mass, T-score and Z-score bone mineral density (BMD) (all, p < 0.05). Greater upper-body flexibility was associated with lower pre-pregnancy BMI; and postpartum indices body weight, BMI, lean mass, fat free mass, fat mass, android fat mass and gynoid fat mass, and with greater GWG (all, p < 0.05). At the 34th g.w., greater CRF was additionally associated with greater postpartum T-score and Z-score BMD (both, p < 0.05). In conclusion, this study reveals that greater PF levels, especially during early pregnancy, may promote a better body composition in the postpartum period. Therefore, clinicians and health promoters should encourage women to maintain or improve PF levels from early pregnancy.

Given that obesity is on the rise today, it is important to find strategies to cope with it, especially during pregnancy.The results of the present study suggest that greater physical fitness during early pregnancy is key to promoting better body composition in the postpartum period.It should be of clinical interest to encourage pregnant women to maintain or improve their physical fitness levels.

The influence of an exercise program in middle-aged women on dietary habits. The FLAMENCO project.

OBJECTIVE: To determine the extent to which following an exercise training program can modify dietary habits and adherence to the Mediterranean diet (MD) compared with a counseling group. METHODS: These are secondary analyses from the FLAMENCO (Fitness League Against MENopause COst) project. The present randomized controlled trial included 150 perimenopausal women who were randomized into counseling (n = 75) or exercise (n = 75) groups. The counseling group attended conferences on a healthy lifestyle. The exercise group followed concurrently a 4-month (60 min/session, 3 d/wk) training and did not take part in the conferences. A validated food frequency questionnaire and the Mediterranean diet score were used to assess dietary habits and adherence to the MD, respectively. RESULTS: The fish/shellfish intake was reduced in the counseling group and increased in the exercise group, with a difference between groups of 1.16 servings/wk ( P < 0.01). The counseling group reduced their beer intake, and the exercise group increased it, with a difference between groups of 1.07 servings/wk ( P < 0.01). CONCLUSION: The exercise intervention did not have a significant impact on dietary habits or MD adherence scores in perimenopausal women. Notwithstanding, women in the exercise group increased their beer consumption, which might have been promoted by the social meetings after the exercise training.

The Influence of Exercise, Lifestyle Behavior Components, and Physical Fitness on Maternal Weight Gain, Postpartum Weight Retention, and Excessive Gestational Weight Gain.

This study examines (a) the influence of exercise, lifestyle behavior components (sedentary time, physical activity, and sleep and dietary patterns), and physical fitness on maternal weight gain, postpartum weight retention, and excessive gestational weight gain and (b) whether exercise protects against the adverse effects of impaired metabolism and nonoptimal body composition related to excessive gestational weight gain. Subjects were assigned to either a supervised concurrent (aerobic + resistance) exercise program followed 3 days/week (n = 47) or a control group (n = 54). Sedentary time, physical activity, sleep and dietary patterns (assessed by accelerometry and questionnaires), muscle strength (handgrip test), and cardiorespiratory fitness (Bruce test) were determined at gestational Weeks 16 and 33 (early-middle and late pregnancy, respectively), and at 6 weeks postpartum. Weight gain and weight retention were calculated using recorded weights at prepregnancy, early-middle, and late pregnancy, and at 6 weeks postpartum. Birth complications, maternal postpartum body composition, cardiometabolic, and inflammatory markers in maternal and umbilical cord arterial and venous blood, and in colostrum, and mature milk were also recorded. The exercise intervention reduced late weight gain (B = -2.7, SE = 0.83, p = .003) and weight retention (B = -2.85, SE = 1.3, p = .03), independent of any lifestyle behavior component or physical fitness, but did not prevent excessive weight gain. Increasing cardiorespiratory fitness, muscle strength, and sleep duration were associated with a smaller mean weight gain and lower excessive weight gain values (p < .05). Among the participants who experienced excessive weight gain, those who were exercisers had a lower body mass index and systemic tumor necrosis factor-alpha concentration, lower umbilical cord venous tumor necrosis factor-alpha and arterial interferon gamma levels, higher cord arterial interleukin-10 levels, and improved placental function compared with controls (p < .05). In summary, exercise may help optimize gestational weight gain and weight retention, and may attenuate the impaired phenotype related to excessive weight gain. Increasing cardiorespiratory fitness, muscle strength, and sleep duration might help to prevent excessive weight gain during pregnancy.

Associations of physical activity, sedentary time, and physical fitness with mental health during pregnancy: The GESTAFIT project.

PURPOSE: This study was aimed to analyze the associations of objectively measured physical activity (PA), sedentary time, and physical fitness with mental health in the early second trimester (16 ± 2 gestational weeks) of pregnancy. METHODS: From 229 women initially contacted, 124 pregnant women participated in the present cross-sectional study. Data were collected between November 2015 and March 2017. The participants wore Actigraph GT3X+ Triaxial accelerometers for 9 consecutive days to objectively measure their PA levels and sedentary time. A performance-based test battery was used to measure physical fitness. Self-report questionnaires assessed psychological ill-being (i.e., negative affect, anxiety, and depression), and psychological well-being (i.e., emotional intelligence, resilience, and positive affect). Linear regression analyses were adjusted for age, educational level, accelerometer wear time, miscarriages, and low back pain. RESULTS: Moderate-to-vigorous PA was negatively associated with depression (ß = -0.222, adjusted R2 = 0.050, p = 0.041). Higher levels of sedentary time were negatively associated with positive affect (ß = -0.260, adjusted R2 = 0.085, p = 0.017). Greater upper-body flexibility was positively associated with better emotional regulation (ß = 0.195, adjusted R2= 0.030, p = 0.047). The remaining associations were not significant (all p > 0.05). CONCLUSION: An active lifestyle characterized by higher levels of moderate-to-vigorous PA and lower levels of sedentary time during pregnancy might modestly improve the mental health of pregnant women. Although previous research has focused on the benefits of cardiorespiratory exercise, the present study shows that only upper-body flexibility is related to emotional regulation in early pregnant women. If the present findings are corroborated in further experimental research, physical exercise programs should focus on enhancing flexibility to promote improvements in emotional regulation during early second-trimester of pregnancy.

Association of Self-Reported Physical Fitness with Pregnancy Related Symptoms the GESTAFIT Project.

We explored the association of physical fitness (PF) with pregnancy-related symptoms, at the 16th and 34th gestational weeks (g.w.). The International Fitness Scale and the Pregnancy Symptoms Inventory were employed to assess self-reported PF and pregnancy-related symptoms, respectively. At the 16th g.w. greater self-reported overall PF was associated with lower incidence of urinary frequency (p = 0.020); greater overall PF, cardiorespiratory fitness (CRF), muscular strength and speed-agility were associated with lower incidence of tiredness-fatigue (all, p < 0.05); greater overall PF and speed-agility were associated with lower incidence of poor sleep (both, p < 0.05); greater CRF and flexibility were associated with lower limitations by tiredness-fatigue (both, p < 0.05); and greater flexibility was associated with lower limitations by poor sleep (p = 0.021). At the 34th g.w. greater self-reported overall PF, CRF and muscular strength were associated with lower incidence of tiredness-fatigue (all, p < 0.05); greater CRF was associated with lower incidence of poor sleep (p = 0.019); and, greater flexibility was associated with lower incidence of increased vaginal discharge (p = 0.023). Adequate levels of PF, especially CRF, may help women to cope with the most endorsed pregnancy-related symptoms and its limitations, especially tiredness-fatigue and poor sleep.

A 16-week concurrent exercise program improves emotional well-being and emotional distress in middle-aged women: the FLAMENCO project randomized controlled trial.

OBJECTIVE: To analyze the influence of a supervised concurrent exercise program on emotional well-being and emotional distress in middle-aged women. METHODS: This randomized controlled trial included 150 middle-aged women recruited for the FLAMENCO project. Participants were allocated into counseling (n = 75) or exercise (n = 75) groups. The counseling group attended conferences on healthy lifestyle (including diet and physical activity topics). The exercise group followed a 60-min concurrent (aerobic + resistance) exercise training 3 days/wk for 16 weeks. Emotional health was assessed with the Positive and Negative Affect Schedule (PANAS) in two diverse timeframes, state (PANAS-S) and trait (PANAS-T) ranging from 10 to 50, where higher scores reflect greater affective emotional health/experience (positive affect subscale) and greater emotional distress (negative affect subscale). The differences between the counseling and exercise groups in PANAS were analyzed by linear regression. RESULTS: The total number of women for the per-protocol analyses was 111 divided into the counseling (n = 53) and exercise (n = 58) groups. After adjusting for body mass index and Mediterranean diet adherence, PANAS-S and PANAS-T-positive affect scores increased by 3.81 and 3.02, respectively, in the exercise group whereas they decreased by 0.15 and increased by 0.51 in the counseling group (both, P < 0.05). PANAS-T negative affect decreased by 4.10 in the exercise group whereas only decreased by 0.9 in the counseling group (P < 0.05). CONCLUSION: A 16-week concurrent exercise program improved emotional experience in middle-aged women. Specifically, women in the exercise group significantly improved their emotional well-being and emotional distress through greater changes in positive affect and negative affect compared with the counseling group.

Influence of dietary habits and Mediterranean diet adherence on menopausal symptoms. The FLAMENCO project.

OBJECTIVE: To explore the association of dietary habits and Mediterranean diet adherence with menopausal symptoms. METHODS: The present study included 172 women recruited from the FLAMENCO project. Menopausal symptoms were assessed with the Kupperman Menopausal Index and the Cervantes Menopause and Health Subscale from the validated Cervantes Scale. A food frequency questionnaire was employed to evaluate dietary habits. Adherence to the Mediterranean diet was assessed with the Mediterranean diet score. RESULTS: Intake of poultry and skimmed dairy products was associated with a worse Kupperman Menopausal Index score (ß: 0.17, P = 0.03 and ß: 0.18, P = 0.01, respectively). On the contrary, soy milk consumption was associated with a better Kupperman Menopausal Index score (ß: -0.17, P = 0.02). Poultry and skimmed dairy were associated with worse scores in the total Cervantes Menopause and Health Subscale score (ß: 0.22, P = <0.01 and ß: 0.19, P = 0.01, respectively), whereas soy milk and vegetables were associated with a better total Cervantes Menopause and Health Subscale score (ß: -0.20, P = 0.01 and ß: -0.17, P = 0.03, respectively). Regarding vasomotor symptoms, a greater consumption of poultry was associated with worse symptomatology (ß: 0.18, P = 0.02), and soy milk consumption was associated with fewer vasomotor symptoms (ß: -0.15, P = 0.04). In addition, women with numerous or severe vasomotor symptoms showed a greater consumption of skimmed dairy products (P < 0.05). CONCLUSIONS: This study seems to indicate that some women with mild menopausal symptoms may derive benefit from lower consumption of poultry and skimmed dairy products and a greater consumption of vegetables and soy milk.

Association of objectively measured physical fitness during pregnancy with maternal and neonatal outcomes. The GESTAFIT Project.

AIM: To analyse i) the association of physical fitness during early second trimester and late pregnancy with maternal and neonatal outcomes; and ii) to investigate whether physical fitness is associated with the type of birth (vaginal or caesarean section). METHODS: Pregnant women from the GESTAFIT Project (n = 159) participated in this longitudinal study. Maternal physical fitness including upper- and lower-body strength, cardiorespiratory fitness (CRF) and flexibility were measured through objective physical fitness tests at the 16th and 34th gestational weeks. Maternal and neonatal outcomes were collected from obstetric medical records. Umbilical arterial and venous blood gas pH and partial pressure of carbon dioxide (PCO2) and oxygen (PO2), were assessed. RESULTS: At the 16th week, greater upper-body muscle strength was associated with greater neonatal birth weight (r = 0.191, p<0.05). Maternal flexibility was associated with a more alkaline arterial pH (r = 0.220, p<0.05), higher arterial PO2 (r = 0.237, p<0.05) and lower arterial PCO2 (r = -0.331, p<0.01) in umbilical cord blood. Maternal CRF at the 16th gestational week was related to higher arterial umbilical cord PO2 (r = 0.267, p<0.05). The women who had caesarean sections had lower CRF (p<0.001) at the 16th gestational week and worse clustered overall physical fitness, both at the 16th (-0.227, p = 0.003, confidence interval (CI): -0.376, -0.078) and 34th gestational week (-0.223; p = 0.018; CI: -0.432, -0.015) compared with the women who had vaginal births. CONCLUSION: Increasing physical fitness during pregnancy may promote better neonatal outcomes and is associated with a decrease in the risk of caesarean section. This trial was registered at ClinicalTrials.gov (NCT02582567) on October 20, 2015.

Association of sedentary time and physical activity levels with immunometabolic markers in early pregnancy: The GESTAFIT project.

OBJECTIVES: To analyze the association of sedentary time and physical activity (PA) intensity levels with immunometabolic markers during early pregnancy; and to examine if meeting the PA recommendations is associated with the immunometabolic profile of pregnant women. METHODS: Fifty Caucasian pregnant women (age: 32.8 ± 4.7 years old, body mass index: 24.2 ± 4.1kg/m2 , gestational age: 17 ± 1.5weeks) participated in this cross-sectional study (from September 2015 through May 2016). Sedentary time and PA intensity levels were objectively measured with triaxial accelerometer (seven consecutive valid days). Fasting serum glucose, total cholesterol, phospholipids, and triglycerides were assessed with standard methods. Serum pro-inflammatory and anti-inflammatory cytokines (fractalkine, interleukin-1ß, interleukin-6, interleukin-8, interleukin-10, interferon-γ, and tumor necrosis factor-α) were measured using Luminex xMAP technology. RESULTS: Sedentary time and PA were not correlated with any glycemic or lipid marker (P > .05). After adjusting for the potential confounders, vigorous PA showed a positive non-significant association with interleukin-6 (P = .06), and bouts of moderate-vigorous PA was inversely associated with interleukin-1ß and interferon-γ (P = .02 and P = .04, respectively). Meeting the PA guidelines was inversely associated with interleukin-1ß and positively associated with interleukin-8 (P = .01 and P = .04, respectively). These associations disappeared after controlling for multiplicity. CONCLUSIONS: Increasing the time spent in moderate-vigorous PA, or meeting the PA recommendations, is associated with the cytokine profile of women without metabolic disruptions in early pregnancy. However, sedentary time and PA do not seem to be associated with glucose or lipid levels. These results should be interpreted cautiously in view of the discrepancies after adjusting for multiple comparisons. Future studies in this novel field of research are warranted before reaching any conclusion.

International Fitness Scale-IFIS: Validity and association with health-related quality of life in pregnant women.

This study aimed (a) to examine the construct validity of the International Fitness Scale (IFIS) to discriminate between different objectively measured physical fitness levels in pregnant women and (b) to assess the extent to which IFIS is able to discriminate between pregnant women with different levels of health-related quality of life (HRQoL). A total of 159 pregnant women were involved in the GESTAtion and FITness project: 106 pregnant women (mean age 32.7, SD 4.4 years) were included. Self-reported physical fitness-that is, cardiorespiratory fitness, muscular strength, flexibility, and overall fitness-was assessed with the IFIS. Physical fitness was objectively measured using the Bruce test, the handgrip strength test and the back-scratch test. The HRQoL was assessed with the 36-item Short Form Health Survey (SF-36). Higher self-reported physical fitness measured with IFIS was associated with higher objectively measured physical fitness (P < .05). There was a linear association so that higher self-reported physical fitness (ie, IFIS; regardless of the fitness component) was related to greater General Health dimension scores (P < .05). Moreover, higher self-reported physical fitness (all components except muscular strength) was associated with better Physical Functioning, lower Bodily Pain and higher Vitality scores (ie, SF-36 components). This linear trend was not seen for objectively measured physical fitness. The results of this study suggest that IFIS might be a useful tool for identifying pregnant women with low or very low physical fitness and with low quality of life health-related. Further research should elucidate whether IFIS can identify women with pregnancy complications before it can be implemented in clinical practice.

Influence of a Concurrent Exercise Training Intervention during Pregnancy on Maternal and Arterial and Venous Cord Serum Cytokines: The GESTAFIT Project.

The aim of the present study was to analyze the influence of a supervised concurrent exercise-training program, from the 17th gestational week until delivery, on cytokines in maternal (at 17th and 35th gestational week, and at delivery) and arterial and venous cord serum. Fifty-eight Caucasian pregnant women (age: 33.5 ± 4.7 years old, body mass index: 23.6 ± 4.1kg/m2) from the GESTAFIT Project (exercise (n = 37) and control (n = 21) groups) participated in this quasi-experimental study (per-protocol basis). The exercise group followed a 60-min 3 days/week concurrent (aerobic-resistance) exercise-training from the 17th gestational week to delivery. Maternal and arterial and venous cord serum cytokines (fractalkine, interleukin (IL)-1ß, IL-6, IL-8, IL-10, interferon (IFN)-γ, and tumor necrosis factor (TNF)-α) were assessed using Luminex xMAP technology. In maternal serum (after adjusting for the baseline values of cytokines), the exercise group decreased TNF-α (from baseline to 35th week, p = 0.02), and increased less IL-1ß (from baseline to delivery, p = 0.03) concentrations than controls. When adjusting for other potential confounders, these differences became non-significant. In cord blood, the exercise group showed reduced arterial IL-6 and venous TNF-α (p = 0.03 and p = 0.001, respectively) and higher concentrations of arterial IL-1ß (p = 0.03) compared to controls. The application of concurrent exercise-training programs could be a strategy to modulate immune responses in pregnant women and their fetuses. However, future research is needed to better understand the origin and clearance of these cytokines, their role in the maternal-placental-fetus crosstalk, and the influence of exercise interventions on them.

Body Composition Changes Following a Concurrent Exercise Intervention in Perimenopausal Women: The FLAMENCO Project Randomized Controlled Trial.

We assessed the effects of a 16-week primary-care-based exercise program on body composition in perimenopausal women. The women (n = 150) were randomized into control (n = 75) or exercise (n = 75) groups. Exercise was provided in a 16-week (60 min/session, 3 days/week) concurrent program. Body composition was measured using dual-energy X-ray absorptiometry. These are secondary analyses of the FLAMENCO Project (Clinical Trials Reference NCT02358109). In the intention-to-treat analyses, the control group showed no changes in body mass index (BMI) between post- and pre-test, whereas the exercise group showed a 0.75 kg/m2 decrease in BMI (95% CI: -1.29 to -0.22; p = 0.006). Gynoid and android fat mass in control group decreased by 98.3 g and 46.1 g after the 16 weeks, whereas they decreased by 213 g and 139 g in the exercise group, respectively (95% CI: -209 to -3.86; p = 0.042 and 95% CI: -164 to -26.9; p = 0.007, respectively). The control group decreased their pelvis bone mineral content by 2.85 g in the post-test compared with the pre-test, whereas the exercise group increased it by 1.13 g (95% CI: 0.93 to 7.81; p = 0.013). Per-protocol analyses showed similar results. These analyses suggest that the exercise intervention decreased fat depositions and BMI. Exercise might improve bone mineral content in specific areas such as the pelvis.

Doctor, ask your perimenopausal patient about her physical fitness; association of self-reported physical fitness with cardiometabolic and mental health in perimenopausal women: the FLAMENCO project.

OBJECTIVE: The aim of this study was to explore the association of self-reported physical fitness (PF) and its components with cardiometabolic and mental health in perimenopausal women. METHODS: These cross-sectional analyses included 191 participants (53 ±â€Š4 y old) from the FLAMENCO project. Self-reported PF was assessed with the International Fitness Scale (IFIS). Body mass index (BMI), fat mass (FM), waist circumference (WC), systolic and diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDL-C), triglycerides, C-reactive protein (CRP), and glucose were measured. The Beck's Depression Inventory, State-Trait Anxiety Inventory, Pittsburgh Sleep Quality Index, Life Orientation Test Revised, and Positive and Negative Affect Schedule were used to assess mental health. RESULTS: After adjusting for potential confounders, greater overall PF was associated with lower BMI, FM, WC (P < 0.001), DBP and CRP, and higher HDL-C (P < 0.05). Cardiorespiratory fitness (CRF), speed-agility, and flexibility were associated with lower BMI, WC, and FM (P < 0.001), and muscle strength (MS) with lower WC and FM (P < 0.05). In addition, CRF, MS, and speed-agility were associated with lower CRP (P < 0.01), and flexibility with enhanced triglycerides and HDL-C (P < 0.05). Overall PF and all its components were associated with lower depression, anxiety, and negative affect (P≤0.01), and greater positive affect (P≤0.05). Overall PF and MS were associated with better sleep quality (P < 0.05), and CRF, MS, and speed-agility with greater optimism (P≤0.05). Finally, overall PF showed evidence of significant association with less pharmaceutical expenditure (B = -7.2, ß=-0.145, P = 0.08). CONCLUSIONS: Self-reported PF was associated with better cardiometabolic and mental health in perimenopausal women. The IFIS might be proposed as an inexpensive, quick, and easy tool in clinical settings.

Association of self-reported physical fitness with pain during pregnancy: The GESTAFIT Project.

AIMS: To explore the association of self-reported physical fitness with bodily, lumbar and sciatic pain, and pain disability during pregnancy. METHODS: The present study sample comprised 159 pregnant women (32.9 ± 4.7 years old). Self-reported physical fitness was assessed with the International Fitness Scale (IFIS), where higher scores indicate greater physical fitness. Bodily pain was assessed with the 36-Item Short Form Health Survey (SF-36), where higher scores indicate lower pain. Lumbar and sciatic pain were measured with a visual analogue scale (VAS). The Oswestry Disability Index (ODI) questionnaire was employed to assess the disability resulting from pain. Measures were assessed at 16th and 34th gestational weeks (g. w.). RESULTS: Pregnant women showed low-moderate pain during pregnancy course. Most of them showed medium self-reported overall physical fitness. At 16th g. w., greater self-reported overall physical fitness and cardiorespiratory fitness were associated with less bodily and lumbar pain, and pain disability (all, P < 0.05). Greater muscular strength was associated with less bodily pain and pain disability (both, P < 0.05). Greater speed-agility was associated with less bodily pain (P < 0.01) and less pain disability (P < 0.05). Self-reported flexibility was not associated with any outcome (P > 0.05). At 34th g. w., greater overall physical fitness and its components were associated with less bodily and sciatic pain (all, P < 0.05). CONCLUSION: Greater self-reported overall physical fitness and its components are associated with less bodily, lumbar and sciatic pain, and reduced pain disability during pregnancy. Future studies are needed to explore whether increasing physical fitness before and during pregnancy could decrease pain in this relevant stage.

Translation and cross-cultural adaptation of the Pregnancy Physical Activity Questionnaire (PPAQ) into Spanish.

Aim: The objective of this study was to translate and transculturally adapt into Spanish the Pregnancy Physical Activity Questionnaire. Methods: The translation procedure included a forward step (translation and synthesis) and a quantitative and qualitative control of the usefulness of the Pregnancy Physical Activity Questionnaire. Afterwards, a prefinal version of the Spanish adapted questionnaire was pretested on 58 pregnant women from Granada (south of Spain). The content, semantic, technical, conceptual, and experiential equivalents of cultural adaptation were discussed by the research members at each step. Results: After the pre-test, two items of the original Pregnancy Physical Activity Questionnaire were replaced by new items that the team considered more culturally appropriate for Spanish pregnant women. Also, some rewording into the European metric system. The response time ranged from 5 to 15 minutes. These changes were well understood and worked properly in the final version. A final version of the Pregnancy Physical Activity Questionnaire was agreed on after a discussion among the research members about the results obtained in the prefinal version. Conclusion: The final Spanish version of the Pregnancy Physical Activity Questionnaire has showed cross-cultural equivalence with the original English version.

Association of sedentary time and physical activity during pregnancy with maternal and neonatal birth outcomes. The GESTAFIT Project.

AIM: (a) To analyse the association of objectively measured sedentary time (ST) and physical activity (PA) during early second trimester of pregnancy with maternal and neonatal birth outcomes; (b) to explore if ST and PA differ between women with vaginal or caesarean section deliveries. METHODS: Ninety-four Caucasian pregnant women (32.9 ± 4.6 years old) participated in this prospective longitudinal study. Triaxial accelerometers were used to assess ST and PA intensity levels for seven consecutive days during second trimester of pregnancy. Birth data were collected from the obstetric medical records. Umbilical cord arterial and venous blood gas (pH, partial pressure of carbon dioxide and oxygen, and oxygen saturation) were analysed after birth. RESULTS: After adjusting for potential confounders, greater ST was associated with higher arterial and venous cord blood partial pressure of carbon dioxide and more acidic arterial and venous pH (all, P < 0.01). Moderate PA, moderate-to-vigorous PA (MVPA), total PA and steps per day were positively associated with arterial cord blood oxygen saturation (all P < 0.05). Steps per day were inversely associated with gestational age at birth (P < 0.01), and duration of first stage of labor (P < 0.05). Total and light PA were associated with a more alkaline pH in umbilical vein (all, P < 0.01). Vigorous PA was inversely associated with the Apgar score (P < 0.01). No significant differences were observed in ST and PA levels between women with vaginal and women with caesarean section deliveries (all, P > 0.10). CONCLUSION: Increasing PA and decreasing ST during pregnancy might promote better maternal and neonatal birth markers.
