Eficacia desde posiciones 1 y 2 en situación de desigualdad en el 15º Campeonato del Mundo de Waterpolo

The aim of this study was twofold: to know if the left-handed players are more effective in the goal categories and getting positive actions, in 1 and 2 position, than the right-handed in the same position at numerical inequality. To ascertain if the shots in 1 and 2 position, are less effective than the rest of the positions in the goal categories. A nomothetic observational, multidimensional and punctual design was used. The sample was the 389 shots and the 182 positive actions of 24 games (12 male and 12 female) at 15th FINA World Championship held in Barcelona. To record the data was used an ad hoc instrument for observation through the Sport Code Version Pro V9. Descriptive and Chi-square test was applied to study the relationship between variables. Left-handed players are more effective than right-handed players are if they are related to the goal and positive action categories in position 1. Shots from position 1 are the second least effective while position 2 is the fifth most effective.El objetivo de este estudio fue doble: saber si los jugadores zurdos son más efectivos en las categorías de gol y obtener acciones positivas, en la posición 1 y 2, que los diestros en la misma posición en la desigualdad numérica.

Effects of a long-term adapted judo program on the health-related physical fitness of children with ASD

[Abstract] Physical fitness is one of the most important physical and mental health aspects for children with Autism Spectrum Disorder (ASD). This study aimed to test the effects of a long-term adapted judo program on the health-related physical fitness of children with ASD. The participants were recruited from various associations of families and schools for children with special needs. Twenty-one children were assigned to an experimental group and nineteen to a control group. The experimental group participated in a six-month adapted judo program consisting of 90 min of practice each week. Health-related physical fitness was measured using the indicators obtained from the ALPHA-fitness battery, the estimated VO2max and the waist/height ratio0.5. Changes within and between groups were analyzed using linear mixed models for repeated measures designs and test-retest reliability of tests requiring a maximum score using the Intraclass Correlation Coefficient (ICC). A judo program tailored for children with ASD can improve the cardio-metabolic health and cardiorespiratory fitness of its participants. The problems involved with administering physical aptitude tests that involve maximum effort or performance in children with ASD cast serious doubts on the reproducibility of their results

Exercise-based interventions to enhance long-term sustainability of physical activity in older adults: a systematic review and meta-analysis of randomized clinical trials

Older adults; Physical activity; AdherenceAdultos mayores; Actividad física; AdherenciaAdults majors; Activitat física; AdherènciaExercise is a form of physical activity (PA). PA is an important marker of health and quality of life in older adults. The purpose of this study was to conduct a systematic review of the literature to assess the effect of exercise-based interventions on an at least six-month follow up PA measure, and to describe the specific strategies implemented during the intervention to strengthen the sustainability of PA in community-dwelling 65+ year-old adults. We registered and conducted a systematic review and meta-analysis (PROSPERO: CRD42017070892) of randomized clinical trials (RCT). We searched three electronic databases during January 2018 to identify RCT assessing any type of exercise-based intervention. Studies had to report a pre-, post-, and at least 6-month post-intervention follow-up. To be included, at least one PA outcome had to be assessed. The effect of exercise-based interventions was assessed compared to active (e.g., a low-intensity type of exercise, such as stretching or toning activities) and non-active (e.g., usual care) control interventions at several time points. Secondary analyses were conducted, restricted to studies that reported specific strategies to enhance the sustainability of PA. The intervention effect was measured on self-reported and objective measures of time spent in PA, by means of standardized mean differences. Standardized mean differences of PA level were pooled. Pooled estimates of effect were computed with the DerSimonian–Laird method, applying a random effects model. The risk of bias was also assessed. We included 12 studies, comparing 18 exercise intervention groups to four active and nine non-active control groups. Nine studies reported specific strategies to enhance the long-term sustainability of PA. The strategies were mostly related to the self-efficacy, self-control, and behavior capability principles based on the social cognitive theory. Exercise interventions compared to active control showed inconclusive and heterogeneous results. When compared to non-active control, exercise interventions improved PA time at the six-months follow up (standardized mean difference (SMD) 0.30; 95%CI 0.15 to 0.44; four studies; 724 participants; I2 0%), but not at the one- or two-years follow-ups. No data were available on the mid- and long-term effect of adding strategies to enhance the sustainability of PA. Exercise interventions have small clinical benefits on PA levels in community-dwelling older adults, with a decline in the observed improvement after six months of the intervention cessation.The present study was funded by United States Department of Health & Human Services National Institutes of Health (NIH), USA, and NIH National Institute on Aging (NIA), USA, (K24 AG057728)

Association of self-reported and device-measured sedentary behaviour and physical activity with health-related quality of life among european older adults

Human movement behaviours such as physical activity (PA) and sedentary behaviour (SB) during waking time have a significant impact on health-related quality of life (HRQoL) in older adults. In this study, we aimed to analyse the association between self-reported and device-measured SB and PA with HRQoL in a cohort of community-dwelling older adults from four European countries. A subsample of 1193 participants from the SITLESS trial (61% women and 75.1 ± 6.2 years old) were included in the analysis. The association between self-reported and objective measures of SB and PA with HRQoL were quantified using Spearman’s Rho coefficients. The strength of the associations between self-reported and device-measured PA and SB with self-rated HRQoL (mental composite score, MCS; physical composite score, PCS) were assessed through multivariate multiple regression analysis. Self-reported and device-measured PA and SB levels showed significant but poor associations with PCS (p < 0.05). The association with MCS was only significant but poor with self-reported light PA (LPA) and moderate-to-vigorous PA (MVPA). In conclusion, the findings of this study suggest that both self-reported and device-measured PA of all intensities were positively and significantly associated, while SB was negatively and significantly associated with the PCS of the SF-12. © 2021 by the authors.

Cost-effectiveness of exercise referral schemes enhanced by self-management strategies to battle sedentary behaviour in older adults: Protocol for an economic evaluation alongside the SITLESS three-armed pragmatic randomised controlled trial

Introduction: Promoting physical activity (PA) and reducing sedentary behaviour (SB) may exert beneficial effects on the older adult population, improving behavioural, functional, health and psychosocial outcomes in addition to reducing health, social care and personal costs. This paper describes the planned economic evaluation of SITLESS, a multicountry three-armed pragmatic randomised controlled trial (RCT) which aims to assess the short-term and long-term effectiveness and cost-effectiveness of a complex intervention on SB and PA in community-dwelling older adults, based on exercise referral schemes enhanced by a group intervention providing self-management strategies to encourage lifestyle change. Methods and analysis: A within-trial economic evaluation and long-term model from both a National Health Service/personal social services perspective and a broader societal perspective will be undertaken alongside the SITLESS multinational RCT. Healthcare costs (hospitalisations, accident and emergency visits, appointment with health professionals) and social care costs (eg, community care) will be included in the economic evaluation. For the cost-utility analysis, quality-adjusted life-years will be measured using the EQ-5D-5L and capability well-being measured using the ICEpop CAPability measure for Older people (ICECAP-O) questionnaire. Other effectiveness outcomes (health related, behavioural, functional) will be incorporated into a cost-effectiveness analysis and cost-consequence analysis. The multinational nature of this RCT implies a hierarchical structure of the data and unobserved heterogeneity between clusters that needs to be adequately modelled with appropriate statistical and econometric techniques. In addition, a long-term population health economic model will be developed and will synthesise and extrapolate within-trial data with additional data extracted from the literature linking PA and SB outcomes with longer term health states. Methods guidance for population health economic evaluation will be adopted including the use of a long-time horizon, 1.5% discount rate for costs and benefits, cost consequence analysis framework and a multisector perspective.

Correlates of Sedentary Behaviour in Adults with Intellectual Disabilities-A Systematic Review

Individuals with intellectual disabilities (ID) are at high risk for high levels of sedentary behaviour. To inform the development of programmes to reduce sedentary behaviour, insight into the correlates is needed. Therefore, the aim of this study is to review the evidence on correlates of sedentary behaviour in adults with ID. We performed a systematic literature search in Ovid Medline, Ovid Embase, Web of Science and Google Scholar up to 19 January 2018, resulting in nine included studies that were published from 2011 to 2018. Correlates were categorized according to the ecological model. Studies predominantly focused on individual level correlates. Of those correlates studied in more than one study, having epilepsy was associated with less sedentary behaviour and inconsistent results were found for sex, genetic syndromes, weight status, physical health, mobility, level of ID, and mental health. Of the few interpersonal and environmental factors studied, only living arrangements were studied in more than one study, with inconsistent results. To date, we have limited and inconclusive evidence about correlates of sedentary behaviour in adults with ID. Only when future studies unravel correlates and determinants, across all domains of the ecological model, will the potential opportunities to improve health by reducing sedentary behaviour come within reach

Inter-rater reliability of a classification system for athletes with intellectual disabilities in adapted judo competitions

Background and Study Aim: The proliferation of adapted judo programs for people with intellectual disabilities has garnered continuous growth in the number of participants in this activity. As a result of this growing popularity, a number of adapted international judo competitions are now being held. The adaptive judo classificatiation system was established to ensure that Special Needs judo athletes could be appropriately divided into categories to ensure their safety within the context of competition. The purpose of this study is knowledge about the reliability of the recently developed classification system for individuals with intellectual disabilities in adapted judo competitions.Material and Methods: The classification system has five levels according to functional criteria. Six raters (experts) evaluated 20 videos of official adapted judo competitions, corresponding to one of the five proposed classification categories. Two methods were used to quantify the degree of inter-rater agreement as to the analysis and classification of the recorded matches. Inter-rater agreement was evaluated using the Intraclass Correlation Coefficient (ICC) and Fleiss-Kappa procedures.Results: Results indicated an excellent degree of inter-rater reliability, showing that the system produces consistent results with different raters.Conclusions: This study represents an important step forward in the classification level of participants in adapted judo competitions for people with intellectual disabilities. Future international adapted judo competitions would benefit from field studies to confirm the reliability of this classification system

Consistencia interna y validez convergente, discriminante y de criterio del Start Back Screening Tool en una muestra colombiana

8 páginasIntroduction: Low back pain (LBP) is a frequent reason for consultation, and one of the main causes of permanent work disability. Stratifying the risk of disability due to LBP allows the development of specific therapeutic interventions; however, such stratification requires valid and reliable instruments. Objective: To determine the internal consistency, as well as the convergent, discriminant, and criterion validity of the Start Back Screening Tool (SBST) questionnaire in a Colombian sample. Materials and methods: Quantitative scale validation study conducted in 68 adult patients with LBP who underwent a physical therapy intervention (10 sessions) between 2019 and 2020 in a clinic located in Chía, Colombia. Participants completed the SBST, the Numerical Pain Rating Scale (NPRS), and the Roland-Morris Disability Questionnaire (RMDQ) at three times: pre-intervention, post-intervention, and after 6 weeks of follow-up (without treatment). The internal consistency of the SBST was determined using Cronbach's alpha, omega, lambda-6, and greatest lower bound (GLB) coefficients. Regarding criterion and construct validity, correlations between the SBST and the NPRS and the RMDQ were assessed using the Pearson’s correlation coefficient. Finally, a repeated measures ANOVA was performed between the SBST mean scores obtained at the three moments in order to estimate its discriminant validity. Results: The internal consistency of the instrument, according to the different coefficients, ranged from acceptable to high (alpha=0.634; omega=0.648; lambda-6=0.664; GLB=0.780). Positive correlations were found between the SBST mean score (mean=3.824; SD=1.892) and the NPRS (r=0.257; p=0.035) and RMDQ (r=0.475; p<0.0010) mean scores, as well as significant differences between pre-intervention, post-intervention, and follow-up SBST mean scores (ANOVA: F=33.722; p<0.001). Conclusion: SBST is a valid and reliable instrument to classify the level of risk of poor prognosis in Colombian patients with LBP.Introducción. El dolor lumbar (DL) es una causa frecuente de consulta y una de las principales causas de incapa-cidad laboral permanente. La estratificación del riesgo de discapacidad por DL permite desarrollar intervenciones terapéuticas específicas; sin embargo, dicha estratificación requiere instrumentos válidos y confiables. Objetivo. Determinar la consistencia interna y la validez convergente, discriminante y de criterio del cuestionario Start Back Screening Tool (SBST) en una muestra colombiana. Materiales y métodos. Estudio cuantitativo de validación de pruebas realizado en 68 pacientes adultos con DL que recibieron una intervención fisioterapéutica (10 sesiones) entre 2019 y 2020 en una clínica de Chía, Colombia. Los participantes diligenciaron el SBST, la escala numérica de clasificación del dolor (ENCD) y el cuestionario Roland Morris Disability (RMD) en tres momentos: pre-intervención, post-intervención y luego de 6 semanas de segui-miento (sin tratamiento). La consistencia interna del SBST se determinó mediante los coeficientes alfa de Cronbach, Omega, lambda-6 y greatest lower bound (GLB). En cuanto a la validez de criterio y de constructo, se evaluaron las correlaciones entre el instrumento y la ENCD y el RMD mediante el coeficiente de correlación de Pearson. Finalmen-te, se realizó un ANOVA de medidas repetidas entre las medias de puntaje del SBST obtenidas en los tres momentos para estimar su validez discriminante. Resultados. La consistencia interna del instrumento, según los diferentes coeficientes, varió entre aceptable y alta (alfa=0.634; omega=0.648; lambda-6=0.664; GLB=0.780). Se observaron correlaciones positivas entre el puntaje promedio en el SBST y los puntajes promedio en la ENCD (r=0.257; p=0.035) y la RMD (r=0.475; p<0.0010), así como diferencias significativas entre los puntajes promedio del SBST pre-intervención, post-intervención y seguimiento (ANOVA: F=33.722; p<0.001). Conclusión. El SBST es un instrumento válido y confiable para clasificar el nivel de riesgo de mal pronóstico en pacientes colombianos con DL
