Effectiveness of manual lymphatic drainage in women with fibromyalgia: A pilot study
No full textBackground
Currently there is no treatment capable of significantly alleviating all the symptoms of fibromyalgia (FM), even though it is a complex syndrome with a high prevalence in the population.
Design
Experimental study using a single-blind, randomised, clinical trial.
Objective
To analyse the efficacy of manual lymphatic drainage (MLD) as an alternative to traditional treatment of fibromyalgia (FM) in women.
Methods
This was an experimental study using a single-blind, randomised, clinical trial of 20 women between 30 and 55 years old with FM. Patients were divided into an experimental group (n = 10) and a control group (n = 10). During the study, 3 measurements of pain (visual analogue scale and algometry), FM impact (Fibromyalgia Impact Questionnaire), sleep quality (Index Pittsburgh), anxiety and depression (Hospital Anxiety and Depression Scale) were recorded. Treatment of the experimental group consisted of 2 weekly MLD sessions for 6 weeks.
Results
The effect of the interaction of MLD showed statistically significant results in Right intercostal space (F2,36 = 3.54; p = 0.04; n2p = 0.16). The sleep quality was significantly better favour of the treatment (F2,36 = 4.16; p = 0.01; n2p = 0.20).
Conclusions
MLD therapy demonstrated effects in the experimental group in contrast to the control group across the intervention period concerning the right intercostal space and sleep-related factors. However, MLD did not result in observable alterations in pain perception
The 8:1:1 Supplementation of Branched-Chain Amino Acids in High-Intensity Training: A Case Study of the Protective Effect on Rhabdomyolysis
Full text linkIntroduction: The increasing prevalence of high-intensity sports activities, notably the burgeoning popularity of CrossFit, underscores the contemporary significance of such physical pursuits. The discernible protective impact of branched-chain amino acids on muscle fatigue and injuries is emerging as a noteworthy area of investigation. Within the realm of sports, integrating BCAA supplementation into dietary practices holds promise for aiding athletes in their recovery, particularly in mitigating Delayed-Onset Muscle Soreness. Methodology: This study adopted an experimental pilot design with repeated measures, employing a controlled and randomized approach through double-blind procedures. The participant engaged in high-intensity activity, specifically the CrossFit Karen® test, which entailed executing 150 wall ball throws (9 kg) to a height of 3 m. The trial incorporated three randomized supplementation conditions: BCAAs in an 8:1:1 ratio or a 2:1:1 ratio or a placebo condition. The participant consumed 15 g daily for 7 days, commencing 72 h prior to the initial blood sample and the first Karen® test. Results: In this study, BCAA supplementation at an 8:1:1 ratio demonstrated a discernible protective effect against muscular damage, as evidenced by creatine kinase values and ratings of perceived exertion
At What Point in the Menstrual Cycle Are the Pelvic Floor Muscles at Their Weakest?
Full text linkPelvic floor muscle (PFM) strength is a critical factor for optimal pelvic floor function. Fluctuations in strength values based on different phases of the menstrual cycle (MC) could signify a need for a paradigm shift in evaluating, approaching, and planning training. This research aims to examine and contrast the pelvic floor muscle strength during different phases of the menstrual cycle. A prospective observational study employing digital assessment with the modified Oxford scale and vaginal dynamometry measurements was performed, in order to assess the baseline strength and the contraction strength of the PFMs in eumenorrheic females at three different phases of the MC: the early follicular phase (EFP), the late follicular phase (LFP), and the mid-luteal phase (MLP). During two complete cycles, tympanic temperature and body weight were measured and the urinary luteinizing hormone concentration was tested to determine the time of ovulation. In total, 216 dynamometric measurements of PFM strength were obtained from eighteen nulliparous women (25.72 ± 5.03 years). There were no differences between the baseline strength (p = 0.886) and the contraction strength (p = 0.756) with the dynamometric speculum. In the post hoc analysis, the baseline strength, contraction strength, and strength showed no significant differences between MC phases. As no differences in PFM strength in women were found, the PFMs do not seem to be weaker at any time during the menstrual cycle. It appears that the assessment, establishment, and monitoring of a PFM training program could be initiated at any point in the cycle
Spanish scientific research activity on human trafficking as seen through bibliometric indicators
No full textThis study analyzes the research on the trafficking of persons carried out by authors affiliated with Spanish institutions through a review of the scientific literature based on a bibliometric analysis of articles indexed in Scopus (2000–2022). The units of analysis were documents, sources, authors, keywords and terms of the abstracts. From each document were collected: authors, title of the document, year, journal, cited by, affiliations, authors by affiliations, abstract, authors’ keywords, references and language of the original document. The analysis was carried out through unidimensional bibliometric indicators related to scientific production, collaboration and dissemination, and multidimensional bibliometric indicators. The results show an increase in the production of articles, in co-authorship, and with research largely concentrated in the academic sphere and with little cooperation with foreign institutions. Secondary research using qualitative methods predominates. There is a focus on sexual exploitation centered on women as victims. This bibliometric review addresses UN Sustainability Goal 5.2: eliminate all forms of violence against all women and girls in the public and private spheres, including trafficking and sexual and other forms of exploitation and has implications for practice, policy, and continued research
From the legend of the bandit to today’s narcoculture: Analysis of a criminal reality from a socio-historical approach
No full textEl fenómeno de la narcocultura no es nuevo en España, pese a que no parece haber recibido hasta el presente un análisis profundo. El narcotráfico, así como el contrabando, se han afrontado tradicionalmente desde una política centrada en la acción judicial y policial que, siendo necesaria, solo es parte de la solución y no puede bastar por sí misma. Tras las redes del narcotráfico -o del contrabando- hay más que una mera empresa delincuencial: existe una cosmovisión, una cultura, una mitología que no sólo justifica y retroalimenta la actividad de sus componentes, sino que, además, fortalece la empresa misma, la dota de valores, la convierte en un medio de vida, medra en la cultura honrada, enfrenta a los vecinos entre sí y cuestiona las bases mismas del sistema, así como la actividad de las Cuerpos y Fuerzas de Seguridad del Estado. Un fenómeno similar al acaecido hace más de un siglo con el bandolerismo y su leyenda, si bien desde parámetros socioculturales y tecnológicos diferentes, que lo tornan todo radicalmente distinto: si la acción decidida de las Autoridades de aquel periodo, vía Guardia Civil, pudo erradicar el bandolerismo y su cultura en apenas cincuenta años, no parece que esa misma estrategia, por muchos recursos de los que se la dote, pueda servir para abordar el complejo problema de las narcoculturas. Este artículo, observando con rigor el pasado, trata de profundizar en las razones del caso con la intención de ofrecer pistas que reconduzcan hacia futuras políticas eficientes y ponderadas
Práctica deportiva saludable, resiliencia del profesorado e inclusión educativa en Imbabura (Ecuador)
Full text linkEl deporte es una potente herramienta para promover inclusión social y mejora la resiliencia de quienes lo practican, tan necesaria para afrontar situaciones de riesgo, el crecimiento personal y el éxito académico-profesional. En el contexto ecuatoriano, los informes de datos oficiales indican que solo el 9.6% de la población con nivel de educación secundaria practica deporte, y la práctica deportiva es superior en la población masculina que la femenina. Nuestro objetivo fue conocer la resiliencia y práctica deportiva del profesorado de secundaria de Imbabura y su valoración y práctica en el aula, para promover una educación que resuelva sus necesidades en este sentido. La metodología fue no experimental, transversal, descriptiva y relacional. La muestra estuvo formada por 878 docentes, evaluados con el CD-RISC y un cuestionario ad hoc de elaboración propia. Los resultados muestran alta práctica deportiva y resiliencia del profesorado. Destaca su autoeficacia y tenacidad. Dan valor a la resiliencia en el aula y trabajan sobre todo el control bajo presión. No hay diferencias significativas en resiliencia por práctica deportiva y sí las hay por género en esa variable a favor de los hombres. Los datos se discuten en la línea de promover pedagogías inclusivas, igualitarias, resilientes y saludables
Derechos humanos y tecnologías de la información y la comunicación
Full text linkEl derecho debe ir adaptándose a los cambios sociales que se producen a lo largo de la historia y, en este
contexto, los derechos humanos poseen un carácter evolutivo y dinámico que permite avanzar en su
reconocimiento, en atención a los valores o ideales del entorno social en el que nos encontramos, marcado por la globalización y el uso de las tecnologías de la información y la comunicación (TIC). Este escenario motiva el reconocimiento de una cuarta generación de derechos humanos, digna de protección internacional.
El propósito de esta investigación es presentar una breve revisión de las generaciones de los derechos
humanos, conectadas con el momento histórico en el que se han desarrollado, con acento en el nacimiento de la cuarta generación. La nueva era digital ha provocado cambios sustanciales en nuestra forma de trabajar, de adquirir bienes y servicios, de relacionarnos y, en definitiva, de vivir. Este cambio social sin precedentes nos obliga a reflexionar sobre el sentido de la relación entre el desarrollo tecnológico y el ser humano. El enfoque de la investigación es cualitativo, con un método reflexivo y crítico, mediante la revisión y el análisis documental de normas y doctrina, para analizar los riesgos que enfrentamos y los ámbitos en los que esa transformación ha sido más relevante. Por último, se describen acciones normativas europeas, para orientar la respuesta jurídica necesaria, que posibilite aprovechar todo el potencial tecnológico que se despliega ante nosotros, sin menoscabo en la protección de los derechos humanos. La investigación pudo constatar que debe proponerse una adecuación del ordenamiento jurídico para asegurar la efectividad de tales derechos
Las variantes de autor: Manuel Villegas López y los manuscritos sobre la vida de John Sutter
No full textEn 1941, el exiliado español Manuel Villegas López publicó en la Editorial Atlántida
de Buenos Aires el libro Vida de Sutter, una biografía novelada sobre el pionero californiano Johann
Augustus Sutter (1803-1880). Este tema ya había sido tratado por, entre otros, Blaise Cendrars, en
su novela L’Or (1925), y Stefan Zweig, en uno de los episodios de Sternstunden der Menschheit
(1927). Incluso había dado lugar en 1936 a dos películas: Sutter’s Gold y Der Kaiser von
Kalifornien. Este artículo estudia las tres variantes de autor que sobre esta figura histórica escribió
Villegas: la primera, de once capítulos, publicada en 1941; la segunda, de treinta y seis capítulos,
cerrada en 1960 con la colaboración de su esposa, Remedios Zalamea Herrera, para un premio
literario e inédita; y la tercera, de siete capítulos, firmada con un seudónimo, también inédita y sin
fechar. Todos estos materiales se han encontrado en el Archivo Familiar, que guarda una parte del
legado de Villegas. El propósito del artículo es utilizar el marco teórico y metodológico de la crítica
textual aplicada al manuscrito moderno para descubrir las variantes: la más reciente, la que tiene
más palabras, la mejor conservada o codex optimus y la editio princeps
No differences in weightlifting overhead pressing exercises kinetics
No full textThis study aimed to compare the kinetics between the push press (PP), push jerk (PJ), and split jerk (SJ). Sixteen resistance-trained participants (12 men and 4 women; age: 23.8 ± 4.4 years; height: 1.7 ± 0.1 m; body mass: 75.7 ± 13.0 kg; weightlifting experience: 2.2 ± 1.3 years; one repetition maximum [1RM] PP: 76.5 ± 19.5 kg) performed 3 repetitions each of the PP, PJ, and SJ at a relative load of 80% 1RM PP on a force platform. The kinetics (peak and mean force, peak and mean power, and impulse) of the PP, PJ, and SJ were determined during the dip and thrust phases. Dip and thrust displacement and duration were also calculated for the three lifts. In addition, the inter-repetition reliability of each variable across the three exercises was analysed. Moderate to excellent reliability was evident for the PP (Intraclass correlation coefficient [ICC] = 0.91–1.00), PJ (ICC = 0.86–1.00), and SJ (ICC = 0.55–0.99) kinetics. A one-way analysis of variance revealed no significant or meaningful differences (p > 0.05, η2 ≤ 0.010) for any kinetic measure between the PP, PJ, and SJ. In conclusion, there were no differences in kinetics between the PP, PJ, and SJ when performed at the same standardised load of 80% 1RM PP
Influence of the Menstrual Cycle on Performance in CrossFit®
Full text linkThe purpose of this study was to compare the fast maximal dynamic strength, maximal dynamic strength, and muscular endurance changes between the follicular phase (FP) and luteal phase (LP) in the menstrual cycle (MC). Fourteen healthy resistance-trained CrossFit® athletes and eumenorrheic women without oral contraception participated in this study (age: 29.64 ± 3.95 years; height: 1.62 ± 0.04 m and mass: 60.43 ± 6.56 kg). A double cross-sectional and descriptive study was developed to evaluate strength, power, and muscular endurance performance in the FP (days 5 to 7) and LP (days 20 to 23). In each assessment, the subjects performed three countermovement jumps (CMJs) for assessing fast maximal dynamic strength using My Jump 2, one-repetition maximum (1-RM) on deep squat for maximal dynamic strength, and the Karen® protocol for muscular endurance. The data were analyzed using a paired sample t-test to determine whether there were any significant differences between FP and LP for all the assessments and the significance was set at p ≤ 0.05. Results revealed no significant differences between the FP and LP in performance: (a) fast maximal dynamic strength (FP: 0.27 ± 0.04 m; LP: 0.29 ± 0.04 m; t = 0.98; p = 0.34; ES = 0.26); (b) maximal dynamic strength (FP: 88.14 ± 12.60 kg; LP: 87.07 ± 12.51 kg; t = 0.90; p = 0.38; ES = 0.24); and (c) muscular endurance (FP: 459.43 ± 92.71 s; LP: 456.93 ± 110.68 s; t = 0.27; p = 0.78; ES = 0.07). CrossFit® performance is not altered during the MC in CrossFit® trained athletes. However, monitoring the MC and its symptoms could be used to adapt the training prescription to the needs and preferences of the athletes
