PurposeThis 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.MethodsFrom 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.ResultsModerate-to-vigorous PA was negatively associated with depression (β = –0.222, adjusted R² = 0.050, p = 0.041). Higher levels of sedentary time were negatively associated with positive affect (β = –0.260, adjusted R² = 0.085, p = 0.017). Greater upper-body flexibility was positively associated with better emotional regulation (β = 0.195, adjusted R²= 0.030, p = 0.047). The remaining associations were not significant (all p > 0.05).ConclusionAn 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.  相似文献

Dynamics of players’ relative positioning during baseline rallies in tennis

Abstract

This study analysed how the relative positioning of players on court influenced patterns of interpersonal coordination in baseline rallies in tennis. We developed a model (PA index) that assigns a weight to the position of each player on court and determines a positional advantage, based on the relative proportionality between the lateral and longitudinal displacement values during rallies. To test the model, data from 27 randomly-selected baseline rallies from three ATP World Tour matches (professional tennis players' tournaments organized by Association of Tennis Professionals) on clay were analysed. Results revealed that the PA index of players on court described their interpersonal coordination dynamics during baseline rallies. It also identified the emergence of rally breaks in the interpersonal coordination patterns of competing dyads that led to a point being scored. Data suggest that positional advantage data may assist coaches in the design of training tasks to enhance players' court coverage and performance during competitive interactions, acting as a valuable tool for performance analysis in tennis.  相似文献   

Reaction time and muscle activation patterns in elite and novice athletes performing a taekwondo kick

ABSTRACT

Fractionated reaction time can be used to determine distinct epochs known as pre-motor, response and movement times (MTs) of a reaction time task. The purpose of this study was to compare elite and novice athletes performing a taekwondo kick in terms of the fractionated reaction time and electromyography (EMG) activation patterns of the muscles of the striking lower limb and the lower back. We hypothesised that the pre-motor time, response time (RT) and MT would be the shorter for elite athletes compared to novices. We collected data on 13 elite and 10 novice athletes when performing a roundhouse kick. The experiment included EMG electrodes placed on five low back and lower extremity muscles and an electrogoniometer placed on the kicking knee. We found that pre-motor time was shorter and the RT was longer for elite athletes than novice athletes. Moreover, the integrated EMG of the main knee extensor does not differ between groups though other leg and trunk muscles do. The results allow coaches and teachers to understand this particular taekwondo kicking movement which could ultimately improve the technique in order to establish training and teaching goals.  相似文献   

Framing Political Change     

Fernando Ramos Arenas  Virginia Martín Jiménez 《Media History》2020,26(2):215-229

This article chooses a comparative approach in order to analyze the role played by mass media during the attempted coup d’état in Spain starting on 23 February 1981 and the opening of the Berlin Wall in November 1989. Both episodes demonstrate the media's capacity to articulate political change through their contextualization of particular events. The text focuses on the capacity of the media to frame political episodes, to generate interpretations and thus provide the basis for specific reactions in different audience groups or political instances. For a short period of time (limited to just some hours), the radio and the press in Spain as well as television in East Germany assumed a ‘para-political’ role and set certain events in motion that led to the end of the coup and the fall of the Wall respectively.  相似文献   

Machismo and higher education: Examining the relation between caballerismo and ethnic identity,support seeking,and sense of connectedness among college Latinos     

Fernando Estrada  Paul Jimenez 《Journal of Latinos & Education》2018,17(3):215-224

Latino men, part of the nation’s largest and fastest-growing minority group, stand to benefit from new knowledge related to factors that positively influence college persistence. In this study, the investigators examined whether machismo—a multidimensional and gendered social construct—was directly and indirectly associated with three outcomes associated with postsecondary success: connectedness at school, ethnic identity, and support-seeking behavior. Hierarchical moderated regression analysis on data from 140 mainly Mexican American undergraduates partially supported the hypotheses. Implications for college counselors and program coordinators are discussed, along with limitations of the study and areas for future scholarship.  相似文献   

Using Project-Based Data in Physics to Examine Television Viewing in Relation to Student Performance in Science     

Fernando Espinoza 《Journal of Science Education and Technology》2009,18(5):458-465

Mass media, particularly television, influence public conceptions and attitudes toward learning science. The discovery of an original method that does not rely on self-reported viewing habits to measure the impact of television on students’ performance in science arose from a study of a unit on electricity in a Physics course. In determining the number of television sets at home and the number of hours of operation, data emerged that allowed an investigation of associations between each of these variables and student performance in physics. A negative impact on performance was found in its consistent decrease as both the number of sets and the time the sets are on increase. These results provide dramatic independent confirmation of the negative impact of television viewing on achievement determined through meta-analysis of many studies, and are also consistent with those in the literature at large, particularly from the Third International Mathematics and Science Study, and the National Assessment of Educational Progress. Furthermore, the totally ‘blind’ participation of the subjects lends a degree of authenticity rarely found in a classically designed study. The findings impact scientific literacy, since performance in science and conceptions of science and scientists, are all inextricably linked.  相似文献   

Perceptions of the Bologna process: what do students’ choices reveal?     

Miguel Portela  Carla Sá  Fernando Alexandre  Ana Rute Cardoso 《Higher Education》2009,58(4):465-474

A major element in the creation of the European area of higher education is the adoption of a common structure of degrees, implying in several countries the reduction of the duration of the first degree to 3 years, which is a controversial change. Cardoso et al. (CESifo Econ Stud 54(2): 229–247, 2008) have analyzed student confidence in the curricula change, quantifying its impact on students’ first choices of academic programs. This paper goes two steps further. First, it concentrates on a variable that better translates total demand for an academic program, namely the total number of students who place the program among their six revealed preferences, instead of just the first option; and, second, an econometric model that better fits the data is estimated. Results confirm a positive impact of the Bologna process on the demand for programs, which varies with program size and across fields of study. Our results complement those in Cardoso et al. (2008), as they uncover that being a program leader, i.e. the only institution in the country that restructured a given program, was associated with higher demand by prospective students, which nevertheless stemmed from their “second best" options and not from their first choices.

Strong delay-independent stability of linear delay systems     

Fúlvia S.S. de Oliveira  Fernando O. Souza 《Journal of The Franklin Institute》2019,356(10):5421-5433

This paper presents a new necessary and sufficient condition for testing the strong delay-independent stability of linear systems subject to a single delay. The proposed method follows from the use of matrix polynomials constraints and the Kalman–Yakubovich–Popov lemma. The resulting condition can be checked exactly by solving a feasibility problem in terms of a linear matrix inequality (LMI). Simple numerical examples are given to show the effectiveness of the proposed method.  相似文献
