Psycho-physiological response in an automatic parachute jump     

Vicente Javier Clemente-Suárez  José Juan Robles-Pérez  Jesús Fernández-Lucas 《Journal of sports sciences》2017,35(19):1872-1878

Parachute jump is an extreme activity that elicits an intense stress response that affects jumpers’ body systems being able to put them at risk. The present research analysed modifications in blood oxygen saturation (BOS), heart rate (HR), cortisol, glucose, lactate, creatine kinase (CK), muscles strength, cortical arousal, autonomic modulation, pistol magazine reload time (PMRT) and state anxiety before and after an automatic open parachute jump in 38 male Spanish soldiers (25.6 ± 5.9 years). A MANOVA with samples as a fixed factor and Effect Size (ES) were conducted. MANOVA showed (Wilks lambda = .225; F = 5.980; P = .000) a significantly increase in cortisol (6.2 ± 3.2 vs. 8.2 ± 4.3 nmol/l; P = .025; ES = .47), HR (75.0 ± 14.6 vs. 87.4 ± 17.3 bpm; P = .004; ES = .72), lactate (1.8 ± 1.2 vs. 4.4 ± 2.2 mmol · l^?1; P = .002; ES = 1.18), sympathetic nervous system and leg strength manifestation after the parachute jump. By contrary BOS, PMRT (55.6 ± 27.6 vs. 48.0 ± 16.7 s; P = .021; ES = .46) and somatic anxiety (SA), evaluated by CSAI2R questionnaire, decreased. An automatic parachute jump increased physiological and cortical response and decreased SA of participants. This stress response can affect the jumpers’ abilities and allow us to have a better understanding of the organism stress response and to improve training for both military and sport parachute jumps.  相似文献   

Independent and joint associations of physical activity and fitness with fibromyalgia symptoms and severity: The al-Ándalus project     

Víctor Segura-Jiménez  Alberto Soriano-Maldonado  Fernando Estévez-López  Inmaculada C. Álvarez-Gallardo  Manuel Delgado-Fernández  Jonatan R. Ruiz 《Journal of sports sciences》2017,35(15):1565-1574

We examined independent and joint associations of objectively measured physical activity (PA) and physical fitness (PF) with pain, fatigue and the overall impact of fibromyalgia in 386 fibromyalgia women aged 51.2 ± 7.6 years. Levels of PA (light, moderate and vigorous) and PF were measured with triaxial accelerometry and the Senior Fitness Test, respectively. We used the Short-Form health survey-36 pain sub-scale and the Multidimensional Fatigue Inventory to assess pain and multiple dimensions of fatigue, respectively. The impact of fibromyalgia was studied with the Revised Fibromyalgia Impact Questionnaire (FIQR). Both, total PA and global PF were independently associated with pain pressure threshold, SF-36 pain, reduced activity, reduced motivation and FIQR total score (all, P ≤ 0.027). The associations between total PA and symptoms were weaker than those observed between global PF and symptoms. Overall, unfit patients with low PA showed a worse profile that fit patients with high PA (all, P ≤ 0.001). In summary, PA and PF are independently associated with pain, fatigue and the overall impact of fibromyalgia in women. Although PF presented greater associations with symptoms, the results suggest that both being physically active and keep adequate fitness levels might be convenient for fibromyalgia women.  相似文献

Collaborations Between Multicultural Educators and Archivists: Engaging Students with Multicultural History Through Archival Research Projects     

Natalia Fernández 《Multicultural Perspectives》2016,18(3):153-158

When multicultural educators and archivists collaborate to design projects that engage students with multicultural history through archival research, students can learn in-depth research skills with primary source documents, creatively share their knowledge, and, on a broader level, engage with their local community history. The projects shared in this article serve as examples of how partnerships between multicultural educators and archivists can occur, the types of projects that can be developed and how they are implemented, and students' responses to their work. The three student projects, including a display, a history guidebook, and an oral history project, are intended to offer a variety of ideas to inspire multicultural educators to reach out to their local archivists to develop archival research projects of their own. And, to promote effective and fruitful partnerships, also included are lessons learned as well as tips for successful collaborations between multicultural educators and archivists.  相似文献   

V + H: Hybrid architecture for DSS and OLTP     

María del Pilar Angeles  Victor González Castro 《International Journal of Information Management》2013,33(6):940-947

Previous research has been done to identify the best pragmatic approach that DBMSs must follow to manage different workloads. Some approaches have followed the “One size fits all” approach, trying to incorporate all features in a row-oriented DBMS (also called horizontal) to manage both OLTP and DSS workloads. Additionally, there have been specialized DBMS, following a columnar approach (also called vertical), that focuses on the growing demand to efficiently manage DSS workloads. This paper proposes a combination of both vertical and horizontal DBMS to best manage OLTP and DSS workloads. We have used mature, commercially available products from a single vendor and developed a custom middleware Decision Query Module that identifies the best option for most efficient execution of a query. This V + H architecture also offers the functionality of a mirrored DB without paying twice for storage.  相似文献   

Del diseño curricular de lengua a las unidades didácticas. Ejes sobre los que articular el área de Lengua y Literatura     

José Calero  Carmen Nicolás 《Cultura y Educación》2013,25(10):3-9

En el actual plan de estudios son los contenidos gramaticales el núcleo vertebrador de los programas de Lengua desde el Ciclo Medio de EGB a COU. El empleo de un metalenguaje que no está al alcance de los alumnos y su monótona repetición año tras año sin apenas variaciones desestimula claramente el aprendizaje. Hay otras fórmulas, más aptas para cada etapa o ciclo, que se exponen en este artículo: la globalización en la Educación Primaria; la organización en torno a ejes temáticos en el ciclo 12–14 y en torno a la tipología del texto o las formas de expresión y los géneros literarios en el ciclo 14–16. Además de dar más variedad a la asignatura de Lengua a lo largo de toda la etapa escolar, el uso de estos ejes permitiría adaptar la enseñanza de la Lengua al nivel de madurez de los alumnos en cada uno de los ciclos  相似文献
