Mediterranean Diet Adherence and Health-Related Quality of Life during Pregnancy: Is the Mediterranean Diet Beneficial in Non-Mediterranean Countries?

This study aimed to examine the association of Mediterranean diet (MD) adherence and MD components with health-related quality of life (HRQoL) in pregnant women from Spain and Sweden. A total of 138 pregnant women from Spain (age: 32.9 ± 4.6 years old) and 302 pregnant women from Sweden (age: 31.3 ± 4.1 years old) were included. MD adherence was assessed with the Mediterranean food pattern (i.e., a MD index) at the 14-16th gestational weeks. HRQoL was assessed with the Spanish and Swedish versions of the 36-item Short-Form Health Survey (SF-36 and RAND-36, respectively) at the 14-16th and 34-37th gestational weeks. A greater MD adherence was associated with better physical functioning, bodily pain, vitality, emotional role, and mental health in cross-sectional associations (2nd trimester) in the Spanish sample (all p < 0.05). Furthermore, a greater MD adherence was associated with lower bodily pain in both Spanish and Swedish samples (both p < 0.05) in the 3rd trimester. The associations of MD adherence with pain seem to be explained by a greater intake of fiber, fish, fruits, nuts, and legumes (all p < 0.05). A greater MD adherence, driven by a higher intake of fiber, fish, fruits, nuts, and legumes, was associated with lower pain throughout pregnancy in both Mediterranean and non-Mediterranean populations.

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.

Criterion-related validity and reliability of the 2-km walk test and the 20-m shuttle run test in adults: The role of sex, age and physical activity level.

OBJECTIVES: To analyze the criterion-related validity and the reliability of fitness field tests for evaluating cardiorespiratory fitness in adults, by sex, age, and physical activity level. DESIGN: Cross-sectional. METHODS: During 3 weeks, sociodemographic, anthropometric measurements, a treadmill maximal test, the 2-km walk test, and the 20-m SRT were performed in 410 adults aged 18-64 years. Measured and estimated VO2max (by Oja's and Leger's equations) were analyzed. RESULTS: Measured VO2max was associated with estimated VO2max by the 2-km walk test and 20-m SRT (r = 0.784 and r = 0.875, respectively; both p < 0.01). Bland-Altman analysis showed a mean difference of -0.30 ml* kg-1 * min-1 (p < 0.001, d = -0.141) in the 2-km walk test, and 0.86 ml* kg-1 * min-1 (p = 0.051) in the 20-m SRT. Significant mean differences between test and retest were found in the time to complete the 2-km walk test (-1.48 ±â€¯0.51 s, p = 0.004, d = -0.014) and in the final stage reached in the 20-m SRT (0.04 ±â€¯0.01, p = 0.002, d = 0.015). Non-significant differences were found between test and retest in the estimated VO2max by Oja's (-0.29 ±â€¯0.20 ml* kg-1 * min-1, p > 0.05) and Leger's eqs. (0.03 ±â€¯0.04 ml* kg-1 * min-1, p > 0.05). Moreover, both test results and estimated VO2max equations showed a high test-retest reliability. CONCLUSIONS: Both tests were valid and reliable for evaluating cardiorespiratory fitness in adults aged 18-64 years, regardless of sex, age, and physical activity level.

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.

Assessing the Mediterranean diet adherence during pregnancy: Practical considerations based on the associations with cardiometabolic risk.

OBJECTIVE: The aim of the present study was to provide practical considerations for assessing MD adherence during pregnancy based on the association with cardiometabolic risk. STUDY DESIGN: Longitudinal study. MAIN OUTCOME MEASURES: A food frequency questionnaire was fulfilled by 152 pregnant women at the 16th gestational week (g.w.). We calculated the Mediterranean Food Pattern (MFP), the MD Scale (MDScale), the Short MD questionnaire (SMDQ), the MD Score (MedDietScore), and the MD scale for pregnant women (MDS-P). The cardiometabolic risk score consisted of pre-pregnancy body mass index, blood pressure, glucose, triglycerides, and high-density lipoprotein-cholesterol (at 16th and 34th g.w.). RESULTS: Multiple linear regression models showed that the MFP, the MedDietScore, and the SMDQ were associated with lower cardiometabolic risk at the 16th and 34th g.w. (ß's: -0.193 to -0.415, all p < 0.05); and the MDS-P at the 34th g.w. (ß = -0.349, p < 0.01). A comparison of these models with the J test showed that the MFP and the MedDietScore outperformed the SMDQ at the 16th g.w. (p's < 0.05); while the MedDietScore outperformed the SMDQ, MFP, and MDS-P (p's < 0.05) at the 34th g.w. Receiver-Operating-Characteristic-derived thresholds for the MFP, MedDietScore and MDS-P indices were 21, 30, and 6 points, respectively, to identify women with high cardiometabolic risk. CONCLUSION: The MFP and MedDietScore are recommended to assess MD adherence during pregnancy, as these showed the strongest associations with cardiometabolic risk. Our validated thresholds might assist in the detection of poor dietary patterns during pregnancy.

Criterion-Related Validity of Field-Based Methods and Equations for Body Composition Estimation in Adults: A Systematic Review.

PURPOSE OF REVIEW: Overweight and obesity are associated to health prognosis. Therefore, body composition assessment is an important health outcome, especially in adult population. We analyzed the criterion-related validity of existing field-based methods and equations for body composition estimation in adults aged 19-64 years. RECENT FINDINGS: One hundred studies met inclusion criteria. The field-based methods, waist circumference (WC), body adiposity index (BAI), and body mass index (BMI) are valid to indicate body adiposity. Likewise, several equations, including the classical Durnin/Womersley equation, Jackson/Pollock equation (males), and Jackson, Pollock, and Ward equation (females), are valid to estimate total body fat mass or body fat percentage. Anthropometric field methods can provide a simple, quick, and easy informative indicators of adiposity in adults. Classical equations, such as Durnin/Womersley equation, Jackson/Pollock equation, and Jackson, Pollock, and Ward equation, are still valid to estimate total body fat mass or body fat percentage in adult population. When choosing estimation equations, specific population characteristics, such as age, weight status, or race ethnicity, should be taken into account.

A 16-week multicomponent exercise training program improves menopause-related symptoms in middle-aged women. The FLAMENCO project randomized control trial.

OBJECTIVE: To investigate the influence of a supervised multicomponent exercise training program on menopause-related symptoms, particularly vasomotor symptoms (VMS), in middle-aged women. METHODS: A total of 112 middle-aged women (mean age 52 ± 4 y old, age range 45-60 y) from the FLAMENCO project (exercise [n = 59] and counseling [n = 53] groups) participated in this randomized controlled trial (perprotocol basis). The exercise group followed a multicomponent exercise program composed of 60-minute sessions 3 days per week for 16 weeks. The 15-item Cervantes Menopause and Health Subscale was used to assess the frequency of menopause-related symptoms. RESULTS: After adjusting for body mass index and Mediterranean diet adherence, the subscales measuring menopause-related symptoms and VMSs decreased 4.6 more in the exercise group compared to the counseling group (between-group differences [B]: 95% CI: -8.8 to -0.2; P  = 0.040). The exercise group also showed significant improvements in the subscales of couple relationships (between-group differences [B]: -1.87: 95% CI: -3.29 to - 0.45; P  = 0.010), psychological state (between-group differences [B]: -2.3: 95% CI: -5 to -0.2; P  = 0.035), and VMSs (between-group differences [B]: -4.5: 95% CI: -8.8 to -0.2; p  = 0.040) in the Cervantes Menopause and Health Subscale compared with the counseling group. CONCLUSIONS: A 16-week multicomponent physical exercise program showed a positive effect on menopause- related symptoms especially in couple relationships, psychological state, and VMS, among 45 to 60 year old women.

Predictive Validity of Motor Fitness and Flexibility Tests in Adults and Older Adults: A Systematic Review.

Motor fitness and flexibility have been linked to several health issues. We aimed to investigate the predictive validity of motor fitness and flexibility tests in relation to health outcomes in adults and older adults. Web of Science and PubMed databases were screened for studies published from inception to November 2020. Two authors systematically searched, evaluated, and extracted data from identified original studies and systematic reviews/meta-analysis. Three levels of evidence were constructed: strong, moderate, and limited/inconclusive evidence. In total, 1182 studies were identified, and 70 studies and 6 systematic reviews/meta-analysis were summarized. Strong evidence indicated that (i) slower gait speed predicts falls and institutionalization/hospitalization in adults over 60 years old, cognitive decline/impairment over 55 years old, mobility disability over 50 years old, disability in instrumental activities of daily living (IADL) over 54 years old, cardiovascular disease risk over 45 years old, and all-cause mortality over 35 years old; (ii) impaired balance predicts falls and disability in IADL/mobility disability in adults over 40 years old and all-cause mortality over 53 years old; (iii) worse timed up&go test (TUG) predicts falls and fear of falling over 40 years old. Evidence supports that slower gait speed, impaired balance, and worse TUG performance are significantly associated with an increased risk of adverse health outcomes in adults.

Reliability of Field-Based Fitness Tests in Adults: A Systematic Review.

BACKGROUND: Physical fitness is a powerful predictor of morbidity and mortality, and is therefore a useful indicator for public health monitoring. To assess physical fitness, field-based tests are time-efficient, inexpensive, have minimal equipment requirements, and can be easily administered to a large number of individuals. OBJECTIVE: The objective of this systematic review was to examine the reliability of existing field-based fitness tests used in adults aged 19-64 years. METHODS: A systematic search of two electronic databases (MEDLINE and Web of Science) was conducted from inception to 8 June 2021 by two independent researchers. Each study was classified as high, low, or very low quality according to the description of the participants, the time interval between measurements, the description of the results, and the appropriateness of statistics. Three levels of evidence (strong, moderate, and limited) were established according to the number of studies and the consistency of their findings. The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO reference number, CRD42019118480). RESULTS: Of 17,010 records identified, 129 original studies examining the reliability of field-based fitness tests in adults were considered eligible. The reliability was assessed of tests of cardiorespiratory fitness (33 studies: 30 of high quality), musculoskeletal fitness (92 studies: 78 of high quality), and motor fitness (22 studies, all of high quality). There was strong evidence indicating: (i) the high reliability of the cardiorespiratory fitness tests: 20-m shuttle run, 6-min step, and 6-min walk; (ii) the high reliability of the musculoskeletal fitness tests: handgrip strength, back-leg strength, Sorensen, trunk flexion sustained, 5-reps sit-to-stand, sit-and-reach and toe-touch, and moderate reliability bilateral side bridge and prone bridge tests; and (iii) the moderate reliability and low reliability, respectively, of the motor fitness tests T-test and single-leg stand. We found moderate evidence indicating the moderate or high reliability of the following tests: Chester, sit-up, partial curl-up, flexion-rotation trunk, timed stair ascent, pull-up, bent-arm hang, standing broad jump, hop sequence, trunk lift, timed-up-and-go, and hexagon agility. Evidence for the reliability of balance and gait speed tests was inconclusive. Other field-based fitness tests demonstrated limited evidence, mainly due to there being only few studies. CONCLUSIONS: This review provides an evidence-based proposal of the more reliable field-based fitness tests for adults aged 19-64 years. Our findings identified a need for more high-quality studies designed to assess the reliability of field-based tests of lower and upper body explosive and endurance muscular strength, and motor fitness (i.e., balance and gait speed tests) in adults.

The favourable association of self-reported physical fitness with depression and anxiety during pregnancy. The GESTAFIT project.

We explored the association of self-reported physical fitness with depressive symptoms and anxiety levels during pregnancy. One hundred fifty-five pregnant women (32.9 ± 4.7 years old) participated in the study. Self-reported physical fitness was assessed with the International Fitness Scale, depressive symptoms and state anxiety levels with the Center for Epidemiological Studies-Depression Scale and the State Trait Anxiety Index, respectively, at the 16 and 34 weeks of gestation. In model 1 (adjusted for age and gestational weight gain), greater overall self-reported physical fitness was associated with fewer depressive symptoms at the 16 weeks (p = .004). Greater self-reported cardiorespiratory fitness and muscular strength were associated with lower anxiety levels at the 16 weeks (all, p > .05). Greater overall self-reported physical fitness, cardiorespiratory fitness and speed-agility were associated with lower anxiety levels at the 34 weeks (all, p > .05). These results were also confirmed in model 2 (additionally adjusted for the exercise intervention, sleep quality, educational level, working status and cohabitating), except for cardiorespiratory fitness and anxiety levels at the 16 weeks (p = .09). Greater self-reported physical fitness was associated with lower psychological ill-being during pregnancy. Specifically, at the 16 weeks, greater self-reported overall physical fitness was associated with fewer depressive symptoms, greater self-reported muscular strength with lower anxiety levels; greater self-reported overall physical fitness and speed-agility with lower anxiety levels at the 34 weeks and greater self-reported cardiorespiratory fitness with lower anxiety levels during the pregnancy. Screening of physical fitness may reduce the risk of depression and anxiety and generally improve pregnancy mental health-related quality of life.Highlights Maternal depression and anxiety have prevalence rates between 8 and 36%.Physical fitness enhancement during pregnancy results in less depression and anxiety.Greater physical fitness may provide benefits for the mother mental health.Self-reported physical fitness screening during pregnancy may be useful in clinical settings.

Criterion-Related Validity of Field-Based Fitness Tests in Adults: A Systematic Review.

We comprehensively assessed the criterion-related validity of existing field-based fitness tests used to indicate adult health (19-64 years, with no known pathologies). The medical electronic databases MEDLINE (via PubMed) and Web of Science (all databases) were screened for studies published up to July 2020. Each original study's methodological quality was classified as high, low and very low, according to the number of participants, the description of the study population, statistical analysis and systematic reviews which were appraised via the AMSTAR rating scale. Three evidence levels were constructed (strong, moderate and limited evidence) according to the number of studies and the consistency of the findings. We identified 101 original studies (50 of high quality) and five systematic reviews examining the criterion-related validity of field-based fitness tests in adults. Strong evidence indicated that the 20 m shuttle run, 1.5-mile, 12 min run/walk, YMCA step, 2 km walk and 6 min walk test are valid for estimating cardiorespiratory fitness; the handgrip strength test is valid for assessing hand maximal isometric strength; and the Biering-Sørensen test to evaluate the endurance strength of hip and back muscles; however, the sit-and reach test, and its different versions, and the toe-to-touch test are not valid for assessing hamstring and lower back flexibility. We found moderate evidence supporting that the 20 m square shuttle run test is a valid test for estimating cardiorespiratory fitness. Other field-based fitness tests presented limited evidence, mainly due to few studies. We developed an evidence-based proposal of the most valid field-based fitness tests in healthy adults aged 19-64 years old.

Association of Self-Reported Physical Fitness during Late Pregnancy with Birth Outcomes and Oxytocin Administration during Labour-The GESTAFIT Project.

We explored (a) the associations between self-reported maternal physical fitness and birth outcomes; (b) whether self-reported maternal physical fitness (PF) is related to the administration of oxytocin to induce or stimulate labour. Pregnant women from the GESTAFIT project randomized controlled trial (n = 117) participated in this prospective longitudinal study. Maternal physical fitness was assessed through the International Fitness Scale at the 34th gestational week. Maternal and neonatal birth outcomes and oxytocin administration were collected from the obstetric medical records. Umbilical arterial and venous cord blood gas were analysed immediately after birth. Self-reported overall fitness, cardiorespiratory fitness, muscular strength and flexibility were not related to any maternal and neonatal birth outcomes (all p > 0.05). Greater speed-agility was associated with a more alkaline arterial (p = 0.04) and venous (p = 0.02) pH in the umbilical cord blood. Women who were administered oxytocin to induce or stimulate labour reported lower cardiorespiratory fitness (p = 0.013, Cohen's d = 0.55; 95% confidence interval (CI): 0.14, 0.93) and flexibility (p = 0.040, Cohen´s d = 0.51; 95% CI: 0.09, 0.89) compared to women who were not administered oxytocin. Greater maternal physical fitness during pregnancy could be associated with better neonatal birth outcomes and lower risk of needing oxytocin administration.

Influence of the degree of adherence to the mediterranean diet and its components on cardiometabolic risk during pregnancy. The GESTAFIT project.

BACKGROUND AND AIMS: Studies regarding dietary patterns and cardiometabolic risk markers during pregnancy are scarce. The aim of the present study was to analyse whether different degrees of adherence to the Mediterranean diet (MD) and the MD components were associated with cardiometabolic markers and a clustered cardiometabolic risk during pregnancy. METHODS AND RESULTS: This study comprised 119 pregnant women from the GEStation and FITness (GESTAFIT) project. Dietary habits were assessed with a food frequency questionnaire at the 16th and 34th gestational weeks (g.w.). The Mediterranean Diet Score was employed to assess MD adherence. The following cardiometabolic markers were assessed: pre-pregnancy body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, triglycerides and high-density lipoprotein cholesterol (HDL-C). A greater MD adherence was associated with a better cardiometabolic status in cross-sectional (16th g.w. and 34th g.w.) and prospective analyses (MD adherence at the 16th g.w. and cardiometabolic markers at the 34th g.w.; SBP, DBP and HDL-C; all, p < 0.05). Participants with the highest MD adherence (Tertile 3) had a lower clustered cardiometabolic risk than those with the lowest MD adherence (Tertile 1) at the 16th and 34th g.w. (both, p < 0.05). A higher intake of fruits, vegetables and fish and a lower intake of refined cereals and red meat and subproducts were associated with a lower cardiometabolic risk during pregnancy (all, p < 0.05). CONCLUSION: A higher MD adherence, a greater intake of fruits, vegetables and fish and a lower intake of refined cereals and red meat and subproducts showed a cardioprotective effect throughout gestation.

Exercise-Induced Muscle Damage in Postmenopausal Well-Trained Women.

BACKGROUND: Sex hormone deprivation derived from menopause may affect exercise-induced muscle damage (EIMD). No studies have previously evaluated this response between postmpenopausal and premenopausal eumenorrheic women over the menstrual cycle. HYPOTHESIS: Postmenopausal women will present higher EIMD markers than premenopausal women, especially in comparison with the menstrual cycle phases where sex hormone concentrations are higher. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: Thirteen postmenopausal and 19 eumenorrheic women, all of them resistance-trained, performed an eccentric squat-based exercise. The postmenopausal group performed 1 bout of exercise, while the eumenorrheic group performed 3 bouts coinciding with the early follicular, late follicular, and mid-luteal phases ot their menstrual cycle. Muscle soreness, countermovement jump, creatine kinase (CK), myoglobin, lactate dehydrogenase, interleukin-6, tumor necrosis factor-α, and C-reactive protein were evaluated before and postexercise. RESULTS: The expected differences in sex hormones were observed between groups (P < 0.001) according to their reproductive status. Postexercise increases in CK, myoglobin, and muscle soreness (168.2 ± 45.5 U/L, 123.1 ± 41.5 µg/L, and 20.7 ± 21.3 mm, respectively) were observed in comparison with baseline (136.2 ± 45.5 U/L, 76.9 ± 13.8 µg/L, and 2.7 ± 4.2 mm, respectively). Myoglobin values at baseline in postmenopausal women were higher compared with premenopausal women in the aforementioned menstrual cycle phases, respectively (62.8 ± 8.2, 60.4 ± 7.2, and 60.1 ± 10.6 µg/L; P < 0.001 for all comparisons), which was supported by large effect sizes (0.72-1.08 standardized d units). No postexercise differences were observed between groups in any markers (P > 0.05). CONCLUSION: Despite higher resting levels of myoglobin and lower strength values in postmenopausal than in premenopausal women, EIMD was similar between both reproductive profiles. This suggests a potential benefit of being physically active despite aging and sex hormone deprivation. CLINICAL RELEVANCE: Sex hormone deprivation derived from menopause seems not to influence muscle damage reponse to eccentric exercise in resistance-trained postmenopausal women.

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.

Objectively measured sedentary time and physical activity levels in Spanish pregnant women. Factors affecting the compliance with physical activity guidelines.

The aims of this cross-sectional study were to describe objectively measured sedentary time (ST) and physical activity (PA) levels in Spanish pregnant women, to analyze the degree of compliance with PA guidelines during the early second trimester of pregnancy and to explore sociodemographic and clinical factors associated with meeting these PA guidelines. One hundred and thirty-four Caucasian pregnant women were recruited between October 2015 and October 2017 to participate in this study. Triaxial accelerometers were used to analyze ST andPA levels for seven consecutive valid days. Womenspent512 ± 92.1 minutes daily in sedentary behaviors, and 85 ± 108.2 minutes in moderate-to-vigorous physical activity (MVPA) in bouts of at least 10 minutes. They walked on average 7436 ± 2410steps per day. Only 22% of the study sample complied with the PA guidelines. Having an University degree was related with threefold higher odds of compliance with the PA guidelines (95% confidence interval: 0.096-0.913, p < .05). Binary logistic regressions showed that being primiparous was associated with fivefold higher odds of compliance with the PA guidelines (95% confidence interval 1.658-18.039, respectively, p < .01). Maternal age, BMI, marital status, working status, and previous miscarriages were not associated with compliance with PA guidelines. Pregnant women spent more than a third of the day in sedentary behaviors and the compliance with PA guidelines was less than desirable. Finally, not having an university degree or having children could be factors related to lower odds of compliance with these guidelines, and therefore require special attention from healthcare professionals.

Influence of Dietary Habits and Mediterranean Diet Adherence on Sleep Quality during Pregnancy. The GESTAFIT Project.

We examined the association of the dietary habits and the Mediterranean diet (MD) adherence with sleep quality during pregnancy. A food frequency questionnaire and the Mediterranean Food Pattern were employed to assess dietary habits and MD adherence, respectively. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) global score (n = 150; mean age 32.9 ± 4.6 years). A higher consumption of fruits was associated with better sleep quality at the 16th gestational week (g.w.; p < 0.05). A greater olive oil consumption and a higher MD adherence were associated with better sleep quality at the 16th and 34th g.w. (all, p < 0.05). Contrarily, a higher red meat and subproducts consumption was associated with worse sleep quality at the 34th g.w. (p < 0.05). The group with the highest adherence to the MD (Tertile 3) showed better sleep quality than the group with the lowest adherence (Tertile 1) at the 16th and 34th g.w. (both, p < 0.05). A higher adherence to the MD, a greater intake of fruits and olive oil and a lower intake of red meat and subproducts were associated with better sleep quality along the pregnancy course, especially among sedentary women.
