Influencia de los hábitos deportivos en el conocimiento, calidad e higiene del sueño adolescente / Influence of sports habits on adolescent sleep knowledge, quality and hygiene

El hábito deportivo resulta esencial para el descanso nocturno del adolescente de Bachillerato. Este estudio analiza la influencia de la práctica deportiva sobre tres variables: conocimiento, calidad e higiene del sueño. Los 145 adolescentes (M = 16.72; DE = 0.74) que componen la muestra reportaron un deficiente conocimiento en nociones del sueño (SBS = 12.04), una pobre calidad del sueño (AYA-PSQI-S = 8.36) y una perfectible higiene del sueño (ASHSr = 4.26). Sin embargo, el 83.6% de los estudiantes que realizaban actividad física demostraron puntuaciones medias totales más altas en las tres variables, asumiendo diferencias significativas (p < 0.05) en las dimensiones de duración y eficiencia del sueño, en comparación al alumnado sedentario. Además, según el estudio, el ejercicio actúa como protector ante la deficitaria calidad de sueño y como impulsor de la higiene del sueño. Por su parte, la alta intensidad de la práctica de ejercicio físico está relacionada con un mejor desempeño en la dimensión de duración de sueño y un mayor autoconcepto, teniendo en cuenta que horas de práctica tardías están relacionadas negativamente con la hora de cenar, postergando el descanso. El hábito deportivo influye positivamente en el conocimiento, la calidad y la higiene del sueño adolescente; apostando por el ejercicio de fuerza, a intensidades submáximas y alejadas en la medida posible de la hora de dormir (AU)

Sports habits are essential for the sleep of the adolescent in the high school. This study analyses the influence of sports practice on three variables: sleep knowledge, sleep quality and sleep hygiene. The 145 adolescents (M = 16.72; SD = 0.74) in the sample reported low sleep knowledge (SBS = 12.04), poor sleep quality (AYA-PSQI-S = 8.36) and improvable sleep hygiene (ASHSr = 4.26). However, 83.6% of physically active students showed higher total scores on all three variables, assuming significant differences (p < 0.05) in sleep duration and sleep efficiency compared to sedentary students. Moreover, exercise prevents poor sleep quality and enhance sleep hygiene. On the other hand, high intensity of physical activity correlates with better performance in the sleep duration dimension and a higher self-concept, considering that late practice hours are negatively related to dinner time, delaying rest. The sporting habit has a positive influence on the sleep knowledge, quality and hygiene of adolescents, betting on strength exercise, at submaximal intensities and as far as possible away from bedtime (AU)

Effects of Mindfulness Training and Exercise on Cognitive Function in Older Adults: A Randomized Clinical Trial.

Importance: Episodic memory and executive function are essential aspects of cognitive functioning that decline with aging. This decline may be ameliorable with lifestyle interventions. Objective: To determine whether mindfulness-based stress reduction (MBSR), exercise, or a combination of both improve cognitive function in older adults. Design, Setting, and Participants: This 2 × 2 factorial randomized clinical trial was conducted at 2 US sites (Washington University in St Louis and University of California, San Diego). A total of 585 older adults (aged 65-84 y) with subjective cognitive concerns, but not dementia, were randomized (enrollment from November 19, 2015, to January 23, 2019; final follow-up on March 16, 2020). Interventions: Participants were randomized to undergo the following interventions: MBSR with a target of 60 minutes daily of meditation (n = 150); exercise with aerobic, strength, and functional components with a target of at least 300 minutes weekly (n = 138); combined MBSR and exercise (n = 144); or a health education control group (n = 153). Interventions lasted 18 months and consisted of group-based classes and home practice. Main Outcomes and Measures: The 2 primary outcomes were composites of episodic memory and executive function (standardized to a mean [SD] of 0 [1]; higher composite scores indicate better cognitive performance) from neuropsychological testing; the primary end point was 6 months and the secondary end point was 18 months. There were 5 reported secondary outcomes: hippocampal volume and dorsolateral prefrontal cortex thickness and surface area from structural magnetic resonance imaging and functional cognitive capacity and self-reported cognitive concerns. Results: Among 585 randomized participants (mean age, 71.5 years; 424 [72.5%] women), 568 (97.1%) completed 6 months in the trial and 475 (81.2%) completed 18 months. At 6 months, there was no significant effect of mindfulness training or exercise on episodic memory (MBSR vs no MBSR: 0.44 vs 0.48; mean difference, -0.04 points [95% CI, -0.15 to 0.07]; P = .50; exercise vs no exercise: 0.49 vs 0.42; difference, 0.07 [95% CI, -0.04 to 0.17]; P = .23) or executive function (MBSR vs no MBSR: 0.39 vs 0.31; mean difference, 0.08 points [95% CI, -0.02 to 0.19]; P = .12; exercise vs no exercise: 0.39 vs 0.32; difference, 0.07 [95% CI, -0.03 to 0.18]; P = .17) and there were no intervention effects at the secondary end point of 18 months. There was no significant interaction between mindfulness training and exercise (P = .93 for memory and P = .29 for executive function) at 6 months. Of the 5 prespecified secondary outcomes, none showed a significant improvement with either intervention compared with those not receiving the intervention. Conclusions and Relevance: Among older adults with subjective cognitive concerns, mindfulness training, exercise, or both did not result in significant differences in improvement in episodic memory or executive function at 6 months. The findings do not support the use of these interventions for improving cognition in older adults with subjective cognitive concerns. Trial Registration: ClinicalTrials.gov Identifier: NCT02665481.

A machine learning-based biological aging prediction and its associations with healthy lifestyles: the Dongfeng-Tongji cohort.

This study aims to establish a biological age (BA) predictor and to investigate the roles of lifestyles on biological aging. The 14,848 participants with the available information of multisystem measurements from the Dongfeng-Tongji cohort were used to estimate BA. We developed a composite BA predictor showing a high correlation with chronological age (CA) (r = 0.82) by using an extreme gradient boosting (XGBoost) algorithm. The average frequency hearing threshold, forced expiratory volume in 1 second (FEV1 ), gender, systolic blood pressure, and homocysteine ranked as the top five important features for the BA predictor. Two aging indexes, recorded as the AgingAccel (the residual from regressing predicted age on CA) and aging rate (the ratio of predicted age to CA), showed positive associations with the risks of all-cause (HR (95% CI) = 1.12 (1.10-1.14) and 1.08 (1.07-1.10), respectively) and cause-specific (HRs ranged from 1.06 to ∼1.15) mortality. Each 1-point increase in healthy lifestyle score (including normal body mass index, never smoking, moderate alcohol drinking, physically active, and sleep 7-9 h/night) was associated with a 0.21-year decrease in the AgingAccel (95% CI: -0.27 to -0.15) and a 0.4% decrease in the aging rate (95% CI: -0.5% to -0.3%). This study developed a machine learning-based BA predictor in a prospective Chinese cohort. Adherence to healthy lifestyles showed associations with delayed biological aging, which highlights potential preventive interventions.

Lifestyle in Female Teachers: Educational Intervention Based on Self-Efficacy Theory in the South of Fars Province, Iran.

INTRODUCTION: Today, improving lifestyles and promoting health are basic needs for human society. The main goal in promoting health is to achieve healthy lifestyle behaviors, and self-efficacy is one of the factors influencing people's lifestyle. Therefore, the impact of educational intervention based on self-efficacy theory on improving lifestyles of the female teachers in Galledar was investigated. METHOD: This study was a semiexperimental study with educational intervention with a control group that was performed on 120 teachers in Galledar. Data collection tools included demographic information questionnaires, health-promoting lifestyle questionnaires, and Sherry's self-efficacy questionnaire. Data were analyzed using SPSS 25 software. RESULT: The mean age and standard deviation of teachers in the control and intervention groups were 33.40 ± 5.68 and 32.83 ± 6.46 years, respectively. Health-promoting lifestyle variables are significant correlation with self-efficacy and overall lifestyle index. Six dimensions which consisted of spiritual growth and self-actualization, health responsibility, interpersonal relationships, stress management, exercise and physical activity, and nutrition showed significant statistical differences before and after educational intervention (P = 0.001). CONCLUSION: Due to the sensitive role of teachers as an effective human force in the development and evolution of society and their students' role modeling, the authorities should formulate policies, regulate educational interventions, and design strategies for promoting self-efficacy beliefs and promoting a healthy lifestyle for all teachers. We suggest that other methods and theories of behavior change be used in future studies to promote a healthy lifestyle.

Effectiveness of Health Coaching in Diabetes Control and Lifestyle Improvement: A Randomized-Controlled Trial.

BACKGROUND: The study aimed to look into the effectiveness of a 6-month health coaching intervention for HbA1c and healthy diet in the treatment of patients with type 2 diabetes. METHODS: The study was carried out via a two-armed, randomized controlled trial that included 114 diabetic patients at a medical center in Taiwan. During the 6-month period, the intervention group had health coaching and usual care for 6 months, and the control group had usual care only. The outcome variables were HbA1c level and healthy diet for follow-up measurement in the third and sixth month. RESULTS: The study discovered a significant decrease in HbA1c and health diet improvement after the 6-month health coaching. Patients in the intervention group decreased their daily intake of whole grains, fruits, meats and protein, and fats and oils while increasing their vegetables intake. CONCLUSIONS: Health coaching may be conducive to the blood sugar control and healthy diet of patients with type 2 diabetes. Further study on health coaching with higher-quality evidence is needed.

Lifestyle and the aging brain: interactive effects of modifiable lifestyle behaviors and cognitive ability in men from midlife to old age.

We examined the influence of lifestyle on brain aging after nearly 30 years, and tested the hypothesis that young adult general cognitive ability (GCA) would moderate these effects. In the community-dwelling Vietnam Era Twin Study of Aging (VETSA), 431 largely non-Hispanic white men completed a test of GCA at mean age 20. We created a modifiable lifestyle behavior composite from data collected at mean age 40. During VETSA, MRI-based measures at mean age 68 included predicted brain age difference (PBAD), Alzheimer's disease (AD) brain signature, and abnormal white matter scores. There were significant main effects of young adult GCA and lifestyle on PBAD and the AD signature (ps ≤ 0.012), and a GCA-by-lifestyle interaction on both (ps ≤ 0.006). Regardless of GCA level, having more favorable lifestyle behaviors predicted less advanced brain age and less AD-like brain aging. Unfavorable lifestyles predicted advanced brain aging in those with lower age 20 GCA, but did not affect brain aging in those with higher age 20 GCA. Targeting early lifestyle modification may promote dementia risk reduction, especially among lower reserve individuals.

ABSTRACT Introduction: Physical exercise has a positive effect on the health of individuals. Long-term sedentary behavior can induce coronary heart disease, hypertension, diabetes, and other chronic diseases. Lack of physical exercise has become the fourth leading cause of death worldwide. Therefore, youth sports are very important for physical health. Objective: To systematically reveal the influencing factors of adolescents' physical exercise and improve the effectiveness of interventions on adolescents' physical exercise behaviors, this article is based on social ecology theory to study the structural model of adolescents' physical exercise factors. Methods: The thesis considers factors affecting adolescent physical exercise as the research object and uses literature method, questionnaire survey, mathematical statistics, etc., to construct a structural model of factors affecting youth physical exercise, including four primary indicators and 19 secondary indicators. Results: Adolescent physical exercise is affected by the school, family, social and personal factors. Among them, family factors have the greatest impact on young people's physical exercise. Personal factors rank second, school factors, and social factors rank third. Among the family factors, the major influences on youth physical exercise are "parental support," "parents' cognition of physical exercise," and "parental exercise habits." Conclusions: The influencing factors of adolescent physical exercise involve four aspects: family, society, school, and self. Family factors have the greatest impact on adolescent physical exercise, and personal factors are the second, school factors, and social factors are the third.

Promoting Successful Cognitive Aging: A Ten-Year Update.

A decade has passed since we published a comprehensive review in this journal addressing the topic of promoting successful cognitive aging, making this a good time to take stock of the field. Because there have been limited large-scale, randomized controlled trials, especially following individuals from middle age to late life, some experts have questioned whether recommendations can be legitimately offered about reducing the risk of cognitive decline and dementia. Despite uncertainties, clinicians often need to at least make provisional recommendations to patients based on the highest quality data available. Converging lines of evidence from epidemiological/cohort studies, animal/basic science studies, human proof-of-concept studies, and human intervention studies can provide guidance, highlighting strategies for enhancing cognitive reserve and preventing loss of cognitive capacity. Many of the suggestions made in 2010 have been supported by additional research. Importantly, there is a growing consensus among major health organizations about recommendations to mitigate cognitive decline and promote healthy cognitive aging. Regular physical activity and treatment of cardiovascular risk factors have been supported by all of these organizations. Most organizations have also embraced cognitively stimulating activities, a heart-healthy diet, smoking cessation, and countering metabolic syndrome. Other behaviors like regular social engagement, limiting alcohol use, stress management, getting adequate sleep, avoiding anticholinergic medications, addressing sensory deficits, and protecting the brain against physical and toxic damage also have been endorsed, although less consistently. In this update, we review the evidence for each of these recommendations and offer practical advice about behavior-change techniques to help patients adopt brain-healthy behaviors.

Influencia de hábitos saludables sobre el índice de masa corporal en la población de 12-14 años en un área de Murcia (España) / The influence of a healthy lifestyle on body mass index in a sample of 12-14 year old individuals in Murcia (Spain)

FUNDAMENTO: El sobrepeso y la obesidad se relacionan directamente con comorbilidades con graves consecuencias para la salud. El objetivo del estudio fue identificar los principales hábitos de vida modificables que influyen en el desarrollo de la sobrecarga ponderal en adolescentes. Material y método. Estudio transversal, realizado en cuatro de los siete centros de educación secundaria del Área V de Murcia. Se recogió información a través de la Encuesta sobre Hábitos Saludables en Adolescentes (ENHASA), cumplimentada por los padres y que engloba cuatro dimensiones compuestas por hábitos de vida modificables: alimentación, actividad física, nuevas tecnologías, y colegio-amigos. Se obtuvieron los datos de somatometría de los adolescentes y se clasificaron según los referentes de índice de masa corporal (IMC) de la OMS. Las diferencias de puntuaciones entre categorías del IMC se analizaron con ANOVA. RESULTADOS: El cuestionario fue cumplimentado por los padres de 421 adolescentes con edad media de 12 años; el 21,1% presentaban sobrepeso y el 19,7% obesidad. A medida que aumentaba la categoría de IMC disminuía la puntuación obtenida en la dimensión de actividad física (6,36 en normopeso vs 4,45 en obesidad, p < 0,001). Las otras tres dimensiones también mostraron diferencias no significativas de puntuación entre normopeso y obesidad. CONCLUSIONES: Un 40,8% de la muestra estudiada presentó exceso de peso, siendo la actividad física la conducta modificable más relacionada con el IMC, lo que orienta a planear estrategias enfocadas especialmente en el sedentarismo que contribuyan a disminuir esta epidemia nutricional

BACKGROUND: Excess weight and obesity in childhood is directly related to comorbidities that can have serious consequences for health. This study set out to identify the main modifiable lifestyles that influence the development of excess weight and obesity in childhood. METHODS: A cross-sectional study was carried out at seven secondary schools in Area V, Murcia, Spain. Questionnaires completed by parents were used to gather information about healthy habits in adolescents (ENHASA), The surveys consisted of four dimensions made up of modifiable lifestyle factors: nutrition, physical activity, new technologies and schoolmates. The adolescents' somatometric data was measured and classified according to the WHO categories for body mass index (BMI). ANOVA was used to compare the score differences among the BMI groups. RESULTS: The questionnaire was completed by the parents of 421 adolescents with an average age of 12 years. 21.1% presented excess weight and 19.7% obesity. The score obtained by adolescents in the physical activity dimension decreased in the increased BMI group (score in normal weight 6.36 vs. 4.45 in obesity; p < 0.001). The other three dimensions showed insignificant differences in scores between normal weight and obesity groups. CONCLUSION: Excess weight was present in 40.8% of the sample. Physical activity was the modifiable lifestyle to be most markedly linked to BMI. This outcome may help in planning specific strategies for sedentary lifestyles to reduce this dietary epidemic

The fit-active profile to better reflect the benefits of a lifelong vigorous physical activity participation: mini-review of literature and population data.

Physical activity is favourably considered for its effect on metabolic fitness and body composition. This observation is generally supported by observational studies and is concordant with endurance-trained individuals' metabolic and morphological profiles. However, in some contexts, the measurement of physical activity habits may not provide an adequate representation of its benefits. In this paper, we review relevant literature on the respective effects of fitness and physical activity on anthropometric and metabolic variables and the informative potential of a classification based on aerobic fitness and activity indicators. The relevance to defining a profile based on both fitness and activity is reinforced by data from the Quebec Family Study showing that, in both men and women, "fit-active" individuals displayed a much more favourable morphological and metabolic profile than "unfit-inactive" individuals. Moreover, these benefits seemed to be more related to variations in fitness than in physical activity. In summary, evidence suggests that a profile combining information on aerobic fitness and physical activity may better reflect the lifelong impact of physical activity on body composition and health. Novelty: The fit-active profile better reflects the long-term benefits of vigorous physical activity participation on health. The reported benefits seem to be more related to variations in aerobic fitness than to those in physical activity.

The relationship between healthy lifestyles and bone health: A narrative review.

BACKGROUND: Bone health, especially osteoporosis among ageing populations, has become an important topic for both clinical and basic researchers. The relationship between bone health and healthy lifestyles has been frequently discussed. The present study focuses on the relationship between bone health and healthy lifestyles among older adults, based on a global comparison. METHODS: This narrative review was performed by collecting clinical trials, basic research and reviews on lifestyle and bone health in PubMed database. RESULTS: Positive effects of physical activity and negative effects of malnutrition, alcohol abuse, and cigarette smoking on bone health were revealed. The relationship between bone health and drinking coffee and tea is still inconclusive. Moreover, the diversity of each region should be aware when considering healthy lifestyles to improve bone health. CONCLUSION: Healthy lifestyles are highly related to bone health, and different lifestyles may have different influences on regions with a high risk of bone diseases. It is practical to acknowledge the diversity of economic, religious, environmental and geological conditions in each region when providing suitable and effective recommendations for healthy lifestyles that can improve overall bone health.

Association between physical activity and inflammatory markers in community-dwelling, middle-aged adults.

Physical activity has been known to deter inflammatory process; yet, the evidence is scarce in healthy, middle-aged population. We assessed the association between physical activity and inflammatory biomarkers, including high sensitivity (hs) C-reactive protein, interleukin (IL)-1α, -1ß, and -6, tumor necrosis factor (TNF) -α and -ß, and monocyte chemotactic protein (MCP) -1 and -3. Functional and leisure-time physical activity was assessed by the International Physical Activity Questionnaire. Inflammatory biomarkers were measured by multiplex enzyme-linked immunosorbent assay. Compared with highly physically active participants based on total metabolic equivalent of task, the most sedentary group had significantly higher odds ratio and [95% confidence interval] for ≥75th percentile of TNF-α (1.64 [1.10-2.44]), TNF-ß (1.50 [1.09-2.07]), IL-1ß (2.14 [1.49-3.09]), hsIL-1ß (1.72 [1.15-2.58]), IL-6 (1.84 [1.24-1.73]), hsIL-6 (2.05 [1.35-3.12]), and MCP-1 (1.91 [1.28-2.87]) levels. Results for IL-1α and MCP-3 were inconsistent, as the least active group had lower odds for above the median IL-1α (0.65 [0.49-0.95]) and MCP-3 (0.71 [0.54-0.93]) yet higher odds for ≥75th percentile IL-1α (2.36 [1.63-3.42]) and MCP-3 (2.44 [1.63-3.64]) levels. Based on duration of moderate-to-vigorous physical activity, sedentary participants had significantly higher odds for above median (1.40 [1.13-1.73]) and ≥75th percentile (1.33 [1.00-1.77]) IL-1ß compared with those fulfilling the guideline recommendation. Subgroup analyses showed minimal sex differences. Routine inflammatory assessment may help to achieve primordial prevention of cardiovascular and metabolic diseases. Novelty: Healthy, middle-aged adults with physically active lifestyle were generally at lower odds for elevated inflammatory status. The associations persisted regardless of sex, age, comorbidities, adiposity, and diet.

Healthy lifestyle, endoscopic screening, and colorectal cancer incidence and mortality in the United States: A nationwide cohort study.

BACKGROUND: Healthy lifestyle and screening represent 2 major approaches to colorectal cancer (CRC) prevention. It remains unknown whether the CRC-preventive benefit of healthy lifestyle differs by endoscopic screening status, and how the combination of healthy lifestyle with endoscopic screening can improve CRC prevention. METHODS AND FINDINGS: We assessed lifestyle and endoscopic screening biennially among 75,873 women (Nurses' Health Study, 1988 to 2014) and 42,875 men (Health Professionals Follow-up Study, 1988 to 2014). We defined a healthy lifestyle score based on body mass index, smoking, physical activity, alcohol consumption, and diet. We calculated hazard ratios (HRs) and population-attributable risks (PARs) for CRC incidence and mortality in relation to healthy lifestyle score according to endoscopic screening. Participants' mean age (standard deviation) at baseline was 54 (8) years. During a median of 26 years (2,827,088 person-years) follow-up, we documented 2,836 incident CRC cases and 1,013 CRC deaths. We found a similar association between healthy lifestyle score and lower CRC incidence among individuals with and without endoscopic screening, with the multivariable HR per one-unit increment of 0.85 (95% CI, 0.80 to 0.90) and 0.85 (95% CI, 0.81 to 0.88), respectively (P-interaction = 0.99). The fraction of CRC cases that might be prevented (PAR) by endoscopic screening alone was 32% (95% CI, 31% to 33%) and increased to 61% (95% CI, 42% to 75%) when combined with healthy lifestyle (score = 5). The corresponding PAR (95% CI) increased from 15% (13% to 16%) to 51% (17% to 74%) for proximal colon cancer and from 47% (45% to 50%) to 75% (61% to 84%) for distal CRC. Results were similar for CRC mortality. A limitation of our study is that our study participants are all health professionals and predominantly whites, which may not be representative of the general population. CONCLUSIONS: Our study suggests that healthy lifestyle is associated with lower CRC incidence and mortality independent of endoscopic screening. An integration of healthy lifestyle with endoscopic screening may substantially enhance prevention for CRC, particularly for proximal colon cancer, compared to endoscopic screening alone.

Effect of Kidney Function on Relationships between Lifestyle Behaviors and Mortality or Cardiovascular Outcomes: A Pooled Cohort Analysis.

BACKGROUND: Adherence to healthy behaviors reduces risks of cardiovascular disease and death in the general population. However, among people with kidney disease, a group at higher risk for cardiovascular disease, such benefits have not been established. METHODS: We pooled data from three cohort studies with a total of 27,271 participants. Kidney function was categorized on the basis of eGFR (≥60, 45 to <60, and <45 ml/min per 1.73 m2). We used proportional hazard frailty models to estimate associations between healthy behaviors (not smoking, at recommended body mass index [BMI], physical activity, healthy diet, and moderate to no alcohol intake) and outcomes (all-cause death, major coronary events, ischemic stroke, and heart failure events). RESULTS: All recommended lifestyle behaviors were significantly associated with lower risks of death, regardless of eGFR. Not smoking (versus current) and any moderate to vigorous physical activity (versus none) was significantly associated with reduced risks of major coronary and heart failure events, regardless of eGFR. Any (versus no) moderate or vigorous physical activity significantly associated with decreased risk of ischemic stroke events only among those with eGFR ≥60. Moderate to no daily alcohol intake (versus excessive) was significantly associated with an increased risk of major coronary events, regardless of eGFR. For heart failure events, a BMI of 18.5 to 30 associated with decreased risk, regardless of eGFR. Across all eGFR categories, the magnitude of risk reduction for death and all cardiovascular outcomes increased with greater numbers of recommended lifestyle behaviors. CONCLUSIONS: Recommended lifestyle behaviors are associated with lower risk of death and cardiovascular disease events among individuals with or without reduced kidney function, supporting lifestyle behaviors as potentially modifiable risk factors for people with kidney disease.

Efectos del ejercicio físico y el ayuno intermitente en la salud: una revisión sistemática / Effects of physical exercise and intermittent fasting for health: a Systematic review

OBJETIVOS: Esta investigación tuvo como objetivo revisar sistemáticamente la evidencia científica al respecto de los efectos que tiene en la salud el hecho de combinar ejercicio físico y ayuno intermitente, así como determinar si su impacto es mayor que cuando ambas actividades se realizan de forma separada. MATERIAL Y MÉTODO: Se llevó a cabo una búsqueda en MEDLINE a través de PubMed, Scopus, SportDiscus, Cochrane Library y CINAHL, mediante la combinación de las siguientes palabras clave "Intermittent Fasting", "Ramadan", "Time Restricted Feeding" y "Physical Exercise". La calidad metodológica fue determinada mediante la escala Physiotherapy Evidence Database (PEDro). RESULTADOS: De los 711 resultados obtenidos tras la primera búsqueda, cuatro ensayos clínicos aleatorizados (ECAs) fueron definitivamente incluidos en el estudio. La calidad metodológica de los ensayos analizados resultó ser "regular" en tres es-tudios y "buena" en uno de ellos. Los resultados obtenidos muestran que el ayuno combinado con ejercicio resulta ser más eficaz en la mejora de parámetros relacionados con la composición corporal, tales como el peso corporal, el índice de masa corporal (IMC), la circunferencia de cintura, la masa grasa y el porcentaje de masa grasa. También se observó una mejora en la glucosa, la resistencia a la insulina, el colesterol HDL y LDL, la presión arterial sistólica y diastólica, los triglicéridos y el consumo máximo de oxígeno. CONCLUSIONES: La combinación de ayuno intermitente con ejercicio físico tiene efectos beneficiosos en la salud cardiovascular y metabólica. Dicha estrategia parece ser un método efectivo para mejorar la salud de las personas a través de variables relacionadas con la composición corporal, así como con el nivel de glucosa, colesterol y triglicéridos

OBJECTIVES: This research aimed to systematically review the scientific evidence regarding the effects on health of combining exercise and fasting, as well as to determine if their impact is greater than when both activities are performed separately. MATERIAL AND METHOD: A search of following databases was performed: MEDLINE through PubMed, Scopus, SportDiscus, Cochrane Library and CINAHL, by combining the keywords "Intermittent Fasting", "Ramadan", "Time Restricted Feeding" and "Physical Exercise". The methodological quality was determined using the Physiotherapy Evidence Database (PEDro) scale. RESULTS: Of the 711 results found in the first search, only four studies were definitely selected. The methodological quality of the analyzed trials turned out to be "fair" in three studies and "good" in one of them. The results obtained show that fasting combined with exercise turns out to be more effective in improving the body composition-related parameters, such as body weight, body mass index (BMI), waist circumference, fat mass and fat mass percentage. An improvement in glucose, insulin resistance, HDL and LDL cholesterol, systolic and diastolic blood pressure, triglycerides and maximal oxygen uptake were also observed. CONCLUSIONS: The combination of intermittent fasting with physical exercise is an effective and interesting strategy to improve cardiovascular and metabolic health. This strategy appears to be an effective method to improve people's health through variables related to body composition, as well as the level of glucose, cholesterol and triglycerides

Association among daily fish intake, white blood cell count, and healthy lifestyle behaviors in an apparently healthy Japanese population: implication for the anti-atherosclerotic effect of fish consumption.

Higher fish consumption has been reported to be associated with a lower incidence of coronary artery disease. We hypothesized that a higher frequency of fish intake may be associated with lower peripheral white blood cell (WBC) counts, a marker of chronic inflammation, which is known to be involved in the development of atherosclerotic cardiovascular disease (ASCVD), and a healthy lifestyle. This cross-sectional study was conducted between April 2018 and August 2018 at the Health Planning Center of Nihon University Hospital in a cohort of 4105 apparently healthy subjects. The average frequency of fish intake was 2.3 ± 1.3 days per week. The WBC count decreased significantly as the frequency of fish intake (0-2 days, 3-4 days, or 5-7 days per week) increased (s < 0.0001). Multivariate linear regression analysis identified higher weekly frequency of fish intake as a significant independent determinant of a lower WBC count (ß = - 0.051, p = 0.001). Furthermore, as the weekly frequency of fish intake increased, the proportion of habitual cigarette smokers decreased (p = 0.021), that of subjects engaging in habitual aerobic exercises increased (p < 0.0001), and the weekly alcohol intake frequency increased (p < 0.0001). Moreover, the above-mentioned lifestyle behaviors were also independent determinants of the WBC count. These results suggest that a high frequency of fish intake might be associated with healthier lifestyle behaviors as well as lower WBC counts, and thus may both exert beneficial anti-inflammatory effects and represent a component of healthier lifestyle behaviors associated with a lower risk of ASCVD in Japanese. This association may be partially related to the preventive effects of a higher fish intake on ASCVD events.

Multimodal Imaging Brain Markers in Early Adolescence Are Linked with a Physically Active Lifestyle.

The World Health Organization promotes physical exercise and a healthy lifestyle as means to improve youth development. However, relationships between physical lifestyle and human brain development are not fully understood. Here, we asked whether a human brain-physical latent mode of covariation underpins the relationship between physical activity, fitness, and physical health measures with multimodal neuroimaging markers. In 50 12-year old school pupils (26 females), we acquired multimodal whole-brain MRI, characterizing brain structure, microstructure, function, myelin content, and blood perfusion. We also acquired physical variables measuring objective fitness levels, 7 d physical activity, body mass index, heart rate, and blood pressure. Using canonical correlation analysis, we unravel a latent mode of brain-physical covariation, independent of demographics, school, or socioeconomic status. We show that MRI metrics with greater involvement in this mode also showed spatially extended patterns across the brain. Specifically, global patterns of greater gray matter perfusion, volume, cortical surface area, greater white matter extra-neurite density, and resting state networks activity covaried positively with measures reflecting a physically active phenotype (high fit, low sedentary individuals). Showing that a physically active lifestyle is linked with systems-level brain MRI metrics, these results suggest widespread associations relating to several biological processes. These results support the notion of close brain-body relationships and underline the importance of investigating modifiable lifestyle factors not only for physical health but also for brain health early in adolescence.SIGNIFICANCE STATEMENT An active lifestyle is key for healthy development. In this work, we answer the following question: How do brain neuroimaging markers relate with young adolescents' level of physical activity, fitness, and physical health? Combining advanced whole-brain multimodal MRI metrics with computational approaches, we show a robust relationship between physically active lifestyles and spatially extended, multimodal brain imaging-derived phenotypes. Suggesting a wider effect on brain neuroimaging metrics than previously thought, this work underlies the importance of studying physical lifestyle, as well as other brain-body relationships in an effort to foster brain health at this crucial stage in development.

Gender Differences in Healthy Lifestyle Adherence Following Percutaneous Coronary Intervention for Coronary Artery Disease.

BACKGROUND: Coronary artery disease (CAD) is the leading cause of mortality in Australian women. We identified gender differences in healthy lifestyle adherence in patients treated with percutaneous coronary intervention (PCI) for CAD. METHODS: Consecutive patients were prospectively recruited from three Australian institutions (2016-2017). The primary endpoint at 1 year follow-up was healthy lifestyle adherence defined as 3/3 of: a heart-healthy diet, being physically active and not smoking. Secondary endpoints included cardiac rehabilitation attendance, medication use and lipid levels. RESULTS: From 729 participants (n=192, 26.3% women) 56% were adherent to all three lifestyle measures with no gender difference overall. Compared to men, women were less likely to smoke (7.7% versus 12.2%, p<0.001) to be physically active (61.5% versus 78.2%; p<0.0001), attend cardiac rehabilitation (58.2% versus 66.4%; p<0.045), and take statin therapy (85.4% versus 94.7%; p<0.0001). Female gender independently predicted physical inactivity (OR 2.41, 95% CI 1.57-3.68, p<0.001). CONCLUSION: Important gender differences exist in patients treated with PCI for CAD, namely, significant lower physical activity, cardiac rehabilitation attendance and statin use in women. These all represent key targets for gender-specific secondary prevention interventions.
