Weight cycling in combat sports: revisiting 25 years of scientific evidence
2021
Abstract Background As combat sports are classified by body mass, many athletes engage in rapid weight loss (RWL) prior to competition so they can gain an advantage over lighter opponents. Following the weigh-in, athletes engage in rapid weight gain (RWG), whereby some athletes have been able to compete up to three weight categories greater than the official division weighed in at. Results Although the impact of weight cycling on performance remains equivocal, robust scientific evidence indicates serious acute and chronic negative consequences on physiological and health-related parameters. Still, weight cycling remains highly prevalent in combat sports, and interventions to limit or stop t…
Offensive and defensive team performance: relation to successful and unsuccessful participation in the 2010 Soccer World Cup
2013
Delgado-Bordonau, J.L., Domenech-Monforte, C., Guzman, J.F. & Mendez-Villanueva, A. (2013). Offensive and defensive team performance: relation to successful and unsuccessful participation in the 2010 Soccer World Cup. J. Hum. Sport Exerc., 8(4), pp.894-904. The present study was conducted to analyze the impact of selected offensive and defensive performance indicators in relation to teams’ success in the 2010 soccer World Cup. The sample used corresponded to 54 matches played in both the group and knockout stage. The game-related statistics gathered were: total shots, shots on goal, shots off goal, % of shots on goal from total shots, % of shots off goal from total shots, offensive and defe…
Effect of the pacing strategy during half-duration resistance test on the mechanic, metabolic and cardio-respiratory response
2017
Objective: Changes in pacing rhythm are translated into functional and metabolic changes that can be significantly reflected in the final results of an athlete. Method: Ten male subjects, with moderate performance level (age: 25.2 ± 2.2 years; VO2max: 56.9 ± 5.7 ml kgâ1 minâ1), performed four 5-min races with different pacing strategies: constant-pace (CP), record-pace (RP), kicker-pace (KP), incremental-pace (IP). Results: The cardio-respiratory response did not show statistically significant. There were statistically significant differences (p â¤Â 0.05) in the energetic efficiency among the protocols CP vs. RP, CP vs. KP and RP vs. IP. When results were analyzed by partials (1-m…
The pros and cons of the implementation of a chronic care model in European rural primary care: the points of view of European rural general practiti…
2021
Introduction: This article describes the views of European rural general practitioners regarding the strengths, weaknesses, opportunities and threats (SWOT) of the implementation of a chronic care model (CCM) in European rural primary care. Methods: This was a mixed-methods online survey. Data were collected from 227 general practitioners between May and December 2017. Categorical data were analysed using descriptive methods while free-text responses were analysed using qualitative methods. The setting was rural primary care in nine European countries (including Central and Eastern Europe). Main outcomes measures were respondents' evaluations of a chronic care model in their rural heal…
Usage and Dose Response of a Mobile Acceptance and Commitment Therapy App: Secondary Analysis of the Intervention Arm of a Randomized Controlled Trial
2016
Background: Mobile phone apps offer a promising medium to deliver psychological interventions. A mobile app based on Acceptance and Commitment Therapy (ACT) was developed and studied in a randomized controlled trial (RCT). Objective: To study usage metrics of a mobile ACT intervention and dose-response relationship between usage and improvement in psychological flexibility. Methods: An RCT was conducted to investigate the effectiveness of different lifestyle interventions for overweight people with psychological stress. This paper presents a secondary analysis of the group that received an 8-week mobile ACT intervention. Most of the analyzed 74 participants were female (n=64, 86%). Their me…
Prioridades de investigación en salud laboral en España
2008
La investigacion en salud laboral es un elemento crucial para impulsar de manera efectiva las politicas publicas y privadas en seguridad y salud en el trabajo1. En Espana, en los ultimos anos, y a pesar de su insufi ciencia, se han abierto diversas posibilidades de fi nanciacion de la investigacion en salud laboral con el subprograma de seguridad y salud en el trabajo del Plan Nacional I+D+i 2004-2007, el Fondo de Investigaciones Sanitarias, el Fondo de Investigacion de Proteccion Social y el Instituto Nacional de Seguridad e Higiene en el Trabajo, entre otras. Por su especial relevancia hay que mencionar la incorporacion en el Plan Nacional I+D+I 2004-2007 de un Subprograma I+D en Segurida…
Validation of the Marathon Motivation Scale in Chile
2021
The objective of this work was to validate the Marathon Motivation Scale (MOMS) for its application in the Chilean context. The study used a non-experimental, descriptive and transversal design. The sample was non-probability and intentional and was composed of 250 subjects (143 male and 104 female) runners who participated in the International Marathon of Viña del Mar with an average age of 29.8 (TD = 10.1) years. For the analysis of the data, an exploratory factorial analysis was carried out with free parameters, another one with seven factors fixed to the theoretical dimensions and a confirmatory factorial analysis with the items corresponding to the MOMS model. The validity and reliabil…
Vibration effect on ball score test in international vs. national level table tennis
2018
In table tennis, motor skills are crucial for discriminating player level. However, there is a dearth of studies exploring the impact of a vibrational stimulus on performance. Thirty-four male players (age 25 +/- 2 years ; body mass index, BMI 23.4 +/- 1.2 kg.m(-2)) participated in the study. Seventeen played at international level (IL), while the remaining 17 played at national level (NL). The participants underwent a ball-handling test, the ball score, before (PRE) and after (POST) a vibrational stimulus. Intra-class correlation (ICC) for the ball score result showed good reliability (ICC 0.87 for IL and 0.80 for NL). Repeated measures ANOVA showed differences between groups for ball scor…
Temporal Series Analysis on Avoidable Mortality for the Assessment of an Intervention Program in a Hospital
2017
Background: Avoidable mortality (AM) is one of the most important health indicators (HI) and represents the quality of care in a hospital.Objective: This study measured the efficacy of a training program for a hospital healthcare staff to reduce AM.Methods: This epidemiological study on community intervention analyzed time-series data on HI by semesters from 2008 to 2015. The pre-intervention phase was examined from January 2008 to December 2014; the intervention phase was investigated in the first semester of 2015; and the post-intervention phase was examined in the second semester of 2015.Results: Resindicate a series with a rising tendency until the 14th semester and a pronounced descent…
Umbilical Cord Mesenchymal Stromal Cells for Cartilage Regeneration Applications
2022
Chondropathies are increasing worldwide, but effective treatments are currently lacking. Mesenchymal stromal cell (MSCs) transplantation represents a promising approach to counteract the degenerative and inflammatory environment characterizing those pathologies, such as osteoarthritis (OA) and rheumatoid arthritis (RA). Umbilical cord- (UC-) MSCs gained increasing interest due to their multilineage differentiation potential, immunomodulatory, and anti-inflammatory properties as well as higher proliferation rates, abundant supply along with no risks for the donor compared to adult MSCs. In addition, UC-MSCs are physiologically adapted to survive in an ischemic and nutrient-poor environment a…
