Effects of menstrual cycle phases on elasticity index in female soccer players

The aim of this study was to determine the influence of the menstrual cycle on the elasticity index in female soccer players. A quasi-experimental analysis was carried out with a time series design, with a sample of 14 female players between 16 and 23 years (18.50 ± 1.74) where during all the phases of a menstrual cycle they had to perform the Squat Jump and Counter Movement Jump tests in order to calculate the elasticity index. Descriptive, normality, sphericity test and a repeated measures ANOVA with a Bonferroni type Post-Hoc test were performed. The most relevant aspect was that there were significant differences in the elasticity index between the Follicular Phase and the Ovulatory Phase, obtaining higher percentages of elasticity index in this second phase, but there were no significant differences between the other phases. The results obtained determine that the elasticity index is higher in the Ovulatory Phase than in the rest of the phases and this could be mainly due to the oestrogen peak and that there are no significant differences in the Luteal Phase demonstrates the relevance of this hormone with respect to explosive strength and the elasticity index. This study will allow the use of strategies with the intention of being able to optimally place the loads during plyometric training in reference to the menstrual cycle. While menstrual discomfort is subjective, they should be taken into account. Conversely, the elasticity index provides a reliable objective data that assists in designing personalized training programs

Nutrition planning and hydration control during a six-stage Pirineos FIT Endurance trail-running race. A case report

Ultra-endurance competitions are highly demanding sport events for athletes and require a carefully controlled nutrition, hydration and supplementation before, during and after the physical effort. Scientific research has shown a positive relationship between dietetic (caloric and macronutrient ingestion) recommendations and sport performance. This study describes the nutritional and hydration planning applied to an athlete competing at the Pirineos FIT (a semi-self-sufficient trail-running multi-stage event). Diary caloric ingestion was around 4000 Kcal, 550 Kcal were consumed during the race. In general, the athlete maintained the minimal recommendable levels of hydration (2.5% Body Weight Loss) and Borg's Scale of Exertion (RPE) was used to report subjective perception of fatigue after each stage. Hematological and biochemical parameters showed a normal response to endurance physical exercise. Therefore, the nutrition and hydration planning were successfully applied.Nutrición humana y dietétic

Lipid profile, cardiovascular disease and mortality in a Mediterranean high-risk population: The ESCARVAL-RISK study.

The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with all-cause mortality and hospitalization due to cardiovascular events in a high-risk population. This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008-2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to coronary heart disease or stroke. We estimated adjusted rate ratios (aRR), absolute risk differences and population attributable risk associated with adverse lipid profiles. 51,462 subjects were included with a mean age of 62.6 years (47.6% men). During an average follow-up of 3.2 years, 919 deaths, 1666 hospitalizations for coronary heart disease and 1510 hospitalizations for stroke were recorded. The parameters that showed an increased rate for total mortality, coronary heart disease and stroke hospitalization were, respectively, low HDL-Cholesterol: aRR 1.25, 1.29 and 1.23; high Total/HDL-Cholesterol: aRR 1.22, 1.38 and 1.25; and high Triglycerides/HDL-Cholesterol: aRR 1.21, 1.30, 1.09. The parameters that showed highest population attributable risk (%) were, respectively, low HDL-Cholesterol: 7.70, 11.42, 8.40; high Total/HDL-Cholesterol: 6.55, 12.47, 8.73; and high Triglycerides/HDL-Cholesterol: 8.94, 15.09, 6.92. In a population with cardiovascular risk factors, HDL-cholesterol, Total/HDL-cholesterol and triglycerides/HDL-cholesterol ratios were associated with a higher population attributable risk for cardiovascular disease compared to other common biomarkers.S

Bone Marrow-Derived Cells from Male Donors Do Not Contribute to the Endometrial Side Population of the Recipient

Accumulated evidence demonstrates the existence of bone marrow-derived cells origin in the endometria of women undergoing bone marrow transplantation (BMT). In these reports, cells of a bone marrow (BM) origin are able to differentiate into endometrial cells, although their contribution to endometrial regeneration is not yet clear. We have previously demonstrated the functional relevance of side population (SP) cells as the endogenous source of somatic stem cells (SSC) in the human endometrium. The present work aims to understand the presence and contribution of bone marrow-derived cells to the endometrium and the endometrial SP population of women who received BMT from male donors. Five female recipients with spontaneous or induced menstruations were selected and their endometrium was examined for the contribution of XY donor-derived cells using fluorescent in situ hybridization (FISH), telomapping and SP method investigation. We confirm the presence of XY donor-derived cells in the recipient endometrium ranging from 1.7% to 2.62%. We also identify 0.45–0.85% of the donor-derived cells in the epithelial compartment displaying CD9 marker, and 1.0–1.83% of the Vimentin-positive XY donor-derived cells in the stromal compartment. Although the percentage of endometrial SP cells decreased, possibly being due to chemotherapy applied to these patients, they were not formed by XY donor-derived cells, donor BM cells were not associated with the stem cell (SC) niches assessed by telomapping technique, and engraftment percentages were very low with no correlation between time from transplant and engraftment efficiency, suggesting random terminal differentiation. In conclusion, XY donor-derived cells of a BM origin may be considered a limited exogenous source of transdifferentiated endometrial cells rather than a cyclic source of BM donor-derived stem cells

Validación española del cuestionario de estados de animo (BRUMS) en deportistas y no deportistas

The Brunel Mood Scale (BRUMS) is one of the most widely used tools for measuring mood states in sporting contexts. The BRUMS has also proven to be useful for evaluating the impact of exercise on emotions and moods. Specifically, positive mood appears to improve performance by helping athletes to maximally use their skills and promoting a more enjoyable practice. Although BRUMS has been translated to some languages, to our knowledge, a validated Spanish version does not yet exist. Materials and Method: The main purpose, therefore, of this study was to determine the factorial validity of the BRUMS for use with a Spanish sample. A total of 757 (aged between18-65 years) women and men completed the BRUMS. As secondary aims we evaluated overall mood state differences between (a) sporting and non-sporting populations and (b) male and female participants. Results and Discussion: The results showed that a Spanish version of BRUMS is a valuable measure of mood states in adult Spanish-speakers. However, results suggest that a shorter version better fits the six factors. Interestingly we found significant differences between both non-sporting/sporting groups and between women/men. Results are discussed in relation to previous works on sport performance and gender differences.Introducción: El cuestionario de estados de ánimo (BRUMS) es una de las herramientas más utilizadas para medir estados de ánimo en contextos deportivos. El BRUMS también ha demostrado ser útil para evaluar el impacto del ejercicio sobre las emociones y los estados de ánimo. Concretamente, el estado de ánimo positivo parece mejorar el rendimiento al ayudar a los atletas a utilizar al máximo sus habilidades y promover una práctica más agradable. Aunque el BRUMS ha sido traducido a algunos idiomas, aún no existe una versión validada en español. Materiales y Método: El principal objetivo de este estudio fue determinar la validez factorial del BRUMS para su uso en una muestra española. Un total de 757 participantes (entre 18-65 años) completaron el BRUMS. Como objetivos secundarios evaluamos las diferencias de estado de ánimo general entre (a) deportistas y no deportistas y (b) mujeres y hombres. Resultados y Discusión: Los resultados mostraron que una versión en español del BRUMS es una valiosa medida de estados de ánimo en adultos hispano hablantes. Sin embargo, los resultados sugieren que una versión más corta se ajusta mejor a los seis factores. Además, encontramos diferencias significativas entre los grupos de no deportistas y deportistas y en entre mujeres y hombres. Los resultados se discuten en relación a trabajos previos sobre rendimiento deportivo y diferencias de género.Ciencias de la Actividad Física y del Deport
