Reliability and criterion-related validity of the Cooper test in pre-adolescents and adolescents: A systematic review and meta-analysis.

The Cooper test (CT) is used to assess cardiorespiratory fitness (CRF) in pre-adolescents and adolescents, although it was originally developed to assess healthy adults. The aim of this study is to examine the available scientific evidence on the reliability and criterion validity of CT when administered to pre-adolescents and adolescents. Systematic searches were performed in three electronic databases (MEDLINE/PubMed, SPORTDiscuss and Scopus). To examine reliability and validity, four separate meta-analyses were implemented, finding high heterogeneity in studies with low methodological quality. There was a paucity of research regarding absolute reliability, while studies attempting to develop or cross-validate VO2max/VO2peak equations were almost non-existent. Information on the psychometric properties of CT in pre-adolescents under 12 years of age is scarce. The findings of this review cast doubt on the usefulness of CT both in identifying CRF and in determining the impact of strategies developed to improve CRF among pre-adolescents and adolescents.

Feasibility and reliability of the Functional Movement Screen battery in adults with intellectual disability.

BACKGROUND: The feasibility and reliability of the Functional Movement Screen (FMS) battery for predicting injury risk have been widely studied in athletic, military, public service and healthy populations. However, scant research has been carried out in people with disabilities. This study aimed at identifying the feasibility and reliability of the FMS battery when administered to adults with intellectual disability (ID). METHODS: Adults from a residential and day care centre over 18 years of age, diagnosed with ID and able to follow simple instructions, were included in the study. All participants with behavioural or health problems that prevented the completion of the FMS battery were excluded. All exercises were video recorded to assure proper scoring. Three assessors (one trained and two novices) scored each of the FMS subtests performed separately from the videos. Feasibility was based on completion rates. Reliability of the composite test scores was analysed using intraclass correlation coefficients (ICCs). RESULTS: A total of 30 people with ID (mean age: 35.5 ± 7.12 years; 33.3% women) completed all assessments. The battery showed to be feasible, although difficulties when performing two of the subtests were observed among those with moderate and severe ID. Mean total scores from the three assessors ranged from 7.83 to 8.90. An inverse trend was observed indicating that the higher the ID level, the lower the total FMS score. Test-retest reliability was good for the trained assessor (ICC = 0.89) and mostly moderate for both novice assessors (ICC range: 0.60 to 0.76). Moderate to good inter-rater reliability was observed (ICC range: 0.65 to 0.80). CONCLUSION: The FMS battery is a reliable tool that can be performed by people with ID, albeit with certain difficulties, especially in those with moderate to severe impairment. The battery does not seem to be useful for identifying people with ID at risk of suffering a sport injury. Adequately powered, well-designed studies are required to determine if the FMS battery is appropriate for identifying changes in functional performance in this population.

Influence of cognitive impairment on fall risk among elderly nursing home residents.

BACKGROUND: Information relating the severity of cognitive decline to the fall risk in institutionalized older adults is still scarce. This study aims to identify potential fall risk factors (medications, behavior, motor function, and neuropsychological disturbances) depending on the severity of cognitive impairment in nursing home residents. METHODS: A total of 1,167 nursing home residents (mean age 81.44 ± 8.26 years; 66.4% women) participated in the study. According to the MEC, (the Spanish version of the Mini-Mental State Examination) three levels of cognitive impairment were established: mild (20-24) "MCI", moderate (14-19) "MOCI", and severe (≤14) "SCI". Scores above 24 points indicated the absence cognitive impairment (NCI). Information regarding fall history and fall risk during the previous year was collected using standardized questionnaires and tests. RESULTS: Sixty falls (34%) were registered among NCI participants and 417 (43%) among people with cognitive impairment (MCI: 35%; MOCI: 40%; SCI: 50%). A different fall risk model was observed for MCI, MOCI, SCI, and NCI patients. The results imply that the higher the level of cognitive impairment, the greater the number of falls (F1,481 = 113.852; Sig = 0.015), although the level of significance was not maintained when MOCI and SCI participants were compared. Depression, neuropsychiatric disturbances, autonomy constraints in daily life activity performance, and low functional mobility were factors closely associated with fall risk. CONCLUSION: This study provides evidence indicating that fall risk factors do not hold a direct correlation with the level of cognitive impairment among elderly nursing home care residents.

Physical activity in Parkinson's disease: examining prescription sources, patterns, and the influence of quality of life and disease severity. / La actividad física en la enfermedad de Parkinson: identificación de los responsables de su prescripción, hábitos e impacto en la calidad de vida, y de la gravedad de la enfermedad.

INTRODUCTION: Limited research has explored the influence of quality of life (QoL) and disease severity on physical activity (PA) in Parkinson's disease (PD) patients, and the sources of PA prescription and advice for this population. This study aims to expand scientific knowledge on these topics. PATIENTS AND METHODS: Two-hundred eleven PD patients were personally interviewed to collect data on PA levels using the International Physical Activity Questionnaire-Short Form and QoL using the Parkinson's Disease Questionnaire-8. An ad hoc questionnaire gathered information on disease severity (Hoehn and Yahr stages), PA behaviors, and PA recommendations. RESULTS: Weak but significant associations were found between PA levels, disease severity (r: -0.218; p = 0.004), and QoL (r: -0.244; p = 0.001). Most participants (85%) received PA counselling, predominantly from neurologists, either at diagnosis (52%) or shortly after (28%). Before PD onset, ~86% engaged in PA, decreasing to 66% post-diagnosis. Approximately 78% reported changes in PA, including reduced frequency (18.4%) and duration (32.8%), with walking as the primary activity. CONCLUSIONS: Disease severity and QoL significantly affect PA levels in PD patients. Diagnosis is associated with decreased PA frequency and duration, and walking is the preferred activity. Neurologists primarily provide PA advice.

Prevalence and severity of urinary incontinence among male and female competitors and recreational CrossFit® practitioners.

OBJECTIVE: This study aimed to determine the prevalence, severity and type of urinary incontinence (UI) in female and male CrossFit® practitioners. STUDY DESIGN: The study design is an online cross-sectional survey distributed to CrossFit® practitioners across all Spanish regions. The questionnaire included categorical questions related to CrossFit® practice, multiple-choice questions to determine the exercises performed during reported UI symptoms, and The International Consultation on Incontinence Questionnaire Short-Form questionnaire items. RESULTS: Five hundred seventy-one practitioners (34.0 ± 8.37 years, Body Mass Index 24.20 ± 3.34 kg/m2) met inclusion criteria and completed the survey. There were and 316 females and 255 males. Around 45 % of women and 6 % of men reported having UI (p < 0.001). The severity of UI mainly was slight (30.3 % women, 3.5 % men) and moderate (11.7 % women, 2.3 % men) (p < 0.001). Stress and urgent UI were the most prevalent types among women (36 %) and men (5 %) (p < 0.001). CONCLUSIONS: This study found that UI is relatively common among female CrossFit® practitioners, especially in repetitive jumps. The practitioners' profile (amateur/competitor) does not affect the prevalence or severity of UI. Male athletes can also experience urine leakage while performing CrossFit®, although its prevalence is much lower when compared to female practitioners.

Physiotherapy for freezing of gait in Parkinson's disease: a systematic review and meta-analysis. / Fisioterapia para la congelación de la marcha en la enfermedad de Parkinson: revisión sistemática y metaanálisis.

INTRODUCTION: Freezing of gait (FOG) is one of the most severe symptoms associated with Parkinson's disease (PD). Physiotherapy treatment could be an effective strategy for treating FOG, but no systematic review has been carried out in this regard. AIM: To identify the characteristics, methodological quality, and main outcomes of the studies that have analyzed the effects of physiotherapy interventions in FOG up to date, by performing a systematic review and a meta-analysis. PATIENTS AND METHODS: Four electronic databases were searched in order to find randomized controlled trials that provided information regarding the effects of any kind of physiotherapy treatment on FOG. The methodological quality of the included investigations was assessed by means of the PEDro scale. RESULTS: Twelve studies were identified for inclusion into the qualitative analysis, with four randomized controlled trials included in the final meta-analysis. The quality of the trials was generally good. Those physiotherapy modalities including cues were more effective for treating FOG than traditional physiotherapy approaches. The meta-analysis indicated that physiotherapy interventions had a significantly greater impact on FOG than control comparisons. CONCLUSIONS: Physiotherapy treatment, especially those modalities including visual and auditory cueing, should be prescribed to PD patients with FOG. Future studies including PD patients with cognitive impairment and FOG objective measurement tools are need to complete the existing scientific evidence.

TITLE: Fisioterapia para la congelación de la marcha en la enfermedad de Parkinson: revisión sistemática y metaanálisis.Introducción. La congelación de la marcha (CDM) es uno de los síntomas más graves asociados con la enfermedad de Parkinson (EP). El tratamiento fisioterapéutico podría ser una estrategia efectiva para su tratamiento, pero no se ha realizado ninguna revisión sistemática al respecto. Objetivo. Identificar las características, la calidad metodológica y los principales resultados de los estudios que han analizado los efectos de las intervenciones fisioterapéuticas en CDM hasta la fecha, mediante la realización de una revisión sistemática y un metaanálisis. Pacientes y métodos. Se realizaron búsquedas en cuatro bases de datos electrónicas para encontrar ensayos controlados aleatorizados que proporcionaran información con respecto a los efectos de cualquier tipo de tratamiento fisioterapéutico sobre la CDM. La calidad metodológica de las investigaciones se evaluó mediante la escala PEDro. Resultados. Se identificaron 12 estudios para su inclusión en el análisis cualitativo y cuatro ensayos controlados aleatorizados se incluyeron en el metaanálisis final. La calidad de los ensayos fue generalmente buena. Las modalidades de fisioterapia que incluían señales fueron más efectivas para tratar la CDM que los enfoques de fisioterapia tradicionales. El meta­análisis indicó que las intervenciones fisioterapéuticas tuvieron un impacto significativamente mayor sobre la CDM que las comparaciones de control. Conclusiones. El tratamiento fisioterapéutico, especialmente las modalidades que incluyen señales visuales y auditivas, debe prescribirse a los pacientes con EP con CDM. Se necesitan estudios futuros que incluyan pacientes con EP con deterioro cognitivo y herramientas de medición objetiva de la CDM para completar la evidencia científica existente.

Effects of resistance training in multiple sclerosis.

This study examined the effects of an eight-week progressive resistance training on different strength manifestations, muscle mass and functionality in multiple sclerosis patients. Thirteen volunteered patients (average age 43 years; range 35-51) with a confirmed diagnosis by a neurologist and mild to moderate disability participated twice a week in an eight-week progressive resistance training program after an eight-week control period without training. Intensity ranged from 40-70% of their maximal voluntary contraction. Outcome assessments included magnetic resonance image of the right and left thighs, strength manifestations (maximal voluntary contraction, muscular endurance and power), and functionality by the Up and Go test. All outcome assessments remained unaltered during the eight-week control period. After the eight-week strength training period, isometric strength (+16%, p<0.01), muscular endurance (+84%; p<0.001), maximal power (+51%, p<0.001), muscular hypertrophy from slice 6/27 to slice 11/27 of both thighs (p<0.05), and functionality (p<0.001) improved significantly. Moderate resistance training programs can improve muscle function without injuries and can be a promising therapy to delay the functional deterioration in multiple sclerosis patients.

Effects of 2 physiotherapy programs on pain perception, muscular flexibility, and illness impact in women with fibromyalgia: a pilot study.

OBJECTIVE: This study assessed the effect of 2 physiotherapy programs designed to improve flexibility and to reduce the impact of the illness and pain perception in women with the fibromyalgia syndrome (FMS), and compared the effects of the 2 programs in the short and intermediate term. METHODS: Twenty FMS patients were randomly assigned to 2 training groups, one following a program of kinesiotherapy and active muscular stretching and one using techniques of Global Myofascial Physiotherapy, according to the Mézières method. Both groups met twice a week for 12 weeks, for a total of 150 minutes each week. Flexibility and illness impact were measured by means of a standard test, whereas pain was assessed by means of thumb palpation. Measurements were taken at the beginning and end of the program and 24 weeks after its end. RESULTS: Patients had achieved a statistically significant reduction in the severity of the disease and improved their flexibility level by the end of the program, but had returned to initial values after follow-up. Significant differences were not observed between the 2 treatment groups in the initial values or in the results at the end of the program or after the follow-up, so neither program proved better than the other. CONCLUSION: The FMS patients in this study improved their flexibility level and general well-being using both kinesiotherapy and stretching exercises techniques.

[Analysis of the convergent validity of the Spanish short version of the Minnesota Leisure Time Physical Activity Questionnaire (VREM) and the Spanish version of the International Physical Activity Questionnaire in elderly people (IPAQ-E)]. / Análisis de la validez convergente de la Versión reducida en español del cuestionario de actividad física en el tiempo libre de Minnesota (VREM) y de la versión española del Cuestionario internacional de actividad física en personas mayores (IPAQ-E).

BACKGROUND: In our country the Spanish short version of the Minnesota Leisure Time Physical Activity Questionnaire (VREM) and the International Physical Activity Questionnaire in elderly people (IPAQ-E) are considered useful tools for estimating the amount of physical activity (PA) performed by the geriatric population. However, few studies have been carried out on their psychometric properties. Therefore, this research aims to provide information on their convergent validity by analysing the degree of association that both questionnaires show with physical fitness level. MATERIAL AND METHODS: A total of 105 people (mean age: 76.77 (SD=6.01) years; 84.8% women), answered both questionnaires and performed the Senior Fitness Test (SFT), in order to assess their physical fitness level. RESULTS: Significant correlations were found between the SFT and the VREM items related to energy expenditure derived from walking (r=0.227) or from performing sports activities or dancing (r=0.235), and the estimated total energy expenditure (r=0.314). The IPAQ-E did not establish significant associations with any of the variables analysed. Although a certain a priori correlation was observed between the VREM and the IPAQ-E (r=0.447, p<0.001) and the mean difference between both parameters was nil (p=0.553), it was considered that the questionnaires showed a lack of agreement due to the great width found in the range of differences. CONCLUSIONS: The use of the VREM questionnaire is recommended for estimating the amount of PA performed by the geriatric population, as it shows a certain degree of association, albeit weak, with the level of physical fitness.

[Effects of physical exercise in a population with systemic lupus erythematosus: A systematic review]. / Efectos del ejercicio físico en personas con lupus eritematoso sistémico: revisión sistemática.

This systematic review was aimed at analysing the existing scientific evidence regarding the effects of physical exercise on the symptomatology, disease activity, and fitness level in a population with systemic lupus erythematosus. Following the PRISMA checklist, a search was carried out on PubMed, PEDro, and Sportdiscus databases. The PEDro and MINORS checklists were used in order to identify the methodological quality of the studies selected. A total of 14 studies were found, of which 10 were randomised controlled trials, and 4 were comparative studies. The performance of physical exercise led to significant improvements in fitness and fatigue. No adverse effects were registered. None of the studies found reported positive effects on the disease activity. The obtained results imply that the performance of physical exercise is safe for people with systemic lupus erythematosus, although its benefits are reduced mainly to improvements in their fitness and perceived level of fatigue.

The influence of winter and summer seasons on physical fitness in aged population.

Epidemiological studies have described the association between physical fitness and health. Few have reported the impact of seasonal variation on fitness determinants, in elderly. We investigated the effects of summer and winter environmental conditions on physical fitness, in both exercise and non-exercise elders. 371 non-institutionalized older adults (74.1% female; 78.4 ±â€¯5.3 years) randomly recruited from a total sample of 1338 subjects from north of Portugal, were prospectively followed during 1 year and 3 assessments were performed - April (baseline), October (summer season) and April (winter season). Four groups were defined, according to reported habits of exercising: Exercise (EG); Winter Exercise (WG); and Summer Exercise (SG); non-Exercise (nEG). Muscle strength was assessed with handgrip and isometric knee extension test, and aerobic capacity with the 6 min walking test. Repeated measures ANOVA with two between-subjects factors were run for independent variables, considering a three Time points. Significance set at p < .05. Findings show that: (1) men were fitter than women; (2) EG showed better results than nEG (p = .000), but not different than WG or SG, (3) nEG physical fitness was not significantly different from WG and SG; (4) SG and WG showed similar results; (5) there was significant group-by-time interaction for all variables in study. Among elderly, the regular physical exercise determined better cardiorespiratory fitness and levels of strength compared to individuals that were not exercising, however, no season impact was observed. Independently of exercising mode, regular, seasonal or not exercising, the pattern of changes in physical fitness throughout the year was similar.

Heart rate measurement through carotid pulse by primary school children / Medición de la frecuencia cardíaca mediante pulso carotídeo por niños de primaria

This study aimed to determine whether primaryschool children can accurately monitor their heart rate (HR) through manual pulse measurement. Children aged 9 to 12 years manually assessed their HR through the carotid pulse three times in a physical education session; lying down, after submaximal effort and one minute later. Simultaneously, HR was measured by pulsometers. Of 417 children (10.58±0.93 years, 44.8% girls), 40% provided accurate values (<10% error). Concordance analysis showed wide limits of agreement (95% of measurements between 44.76% below and 78.64% above actual HR values). Sex, age and level of effort had no significant influence on the results. Primary school children are not able to accurately measure their HR through the carotid pulse (AU)

Este estudio tuvo como objetivodeterminar si los niños de primaria pueden controlar con precisión su frecuencia cardíaca (FC)mediante la medición manual del pulso. Niños de 9 a 12 años evaluaron manualmente su FC a través del pulso carotídeo tres veces en una sesión deeducación física; tumbados, trasun esfuerzo submáximo y un minuto después. Simultáneamente, se midió la FC mediante pulsómetros. De 417 niños (rango de edad 9 a 12 años, 44,8% niñas), un40% proporcionóvalores precisos (<10% de error). El análisis de concordancia mostró amplios límites de acuerdo (95% de las mediciones situadas entre un 44,76% por debajo y un 78,64% por encima de los valores reales de la FC). El sexo, la edad y el nivel de esfuerzo no tuvieron una influencia significativa en los resultados. Los niños de primaria no son capaces de medir con precisión su FC a través del pulso carotídeo (AU)

Influence of cognitive impairment on the freezing of gait in non demented people with Parkinson's disease. / Influencia del deterioro cognitivo en la congelacion de la marcha en pacientes con enfermedad de Parkinson sin demencia.

INTRODUCTION: Freezing of gait (FOG) is a motor disturbance usually appearing in advanced Parkinson's disease (PD). Cognitive and executive function seems to play an important role in this phenomenon. AIM: To investigate if cognitive and kinematic parameters correlate with FOG in PD patients without dementia. PATIENTS AND METHODS: We conducted an observational cross-sectional study. Participants were classified in two groups: freezers and non-freezers. Clinical information was obtained by Hoehn and Yahr scale, Unified Parkinson's Disease Rating Scale and balance test of Short Physical Performance Battery. Cognitive function was evaluated using Minimental Examination and the Fuld Object Memory Evaluation; executive function was assessed with the Frontal Assessment Battery test. Battery kinematic parameters were assessed by means of gait speed, cadence, stride length and stride time. RESULTS: Twenty-five participants with PD without dementia completed the evaluation. Statistical significant differences between freezers and non-freezers were found in global cognition (p = 0,02), memory (p = 0,04), executive function (p = 0,04), cadence (p = 0,02), stride length (p = 0,04) and stride time (p = 0,01). CONCLUSION: Cognitive parameters may have an important contribution to the manifestation of freezing of gait in PD. These results may have important clinical implications for developing future non-pharmacological and cognitive interventions strategies targeted to PD patients with FOG.

TITLE: Influencia del deterioro cognitivo en la congelacion de la marcha en pacientes con enfermedad de Parkinson sin demencia.Introduccion. La congelacion de la marcha (CDM) es una alteracion motora que suele aparecer en estadios avanzados de la enfermedad de Parkinson (EP). Las funciones cognitivas y ejecutivas parecen tener un papel importante en la aparicion de este fenomeno. Objetivo. Investigar si los parametros cognitivos y cinematicos se correlacionan con la CDM en pacientes con EP sin demencia. Pacientes y metodos. Estudio observacional y transversal. Los participantes se clasificaron en dos grupos: con y sin CDM. La informacion clinica se obtuvo mediante la escala de Hoehn y Yahr, la Unified Parkinson's Disease Rating Scale y la prueba de equilibrio de la Short Physical Performance Battery. La funcion cognitiva se valoro con el miniexamen cognitivo y la Fuld Object Memory Evaluation, y la funcion ejecutiva, con la Frontal Assessment Battery. Los parametros cinematicos se valoraron mediante la velocidad de la marcha, la cadencia, la longitud del paso y el tiempo del paso. Resultados. Veinticinco participantes con EP sin demencia completaron el programa. Se encontraron diferencias estadisticamente significativas entre individuos con y sin CDM en cognicion global (p = 0,02), memoria (p = 0,04), funcion ejecutiva (p = 0,04), cadencia (p = 0,02), longitud del paso (p = 0,04) y tiempo del paso (p = 0,01). Conclusion. Diversos parametros cognitivos pueden contribuir de forma importante en la aparicion de la CDM en la EP. Estos resultados pueden tener implicaciones clinicas relevantes para el desarrollo de estrategias e intervenciones no farmacologicas y cognitivas dirigidas a pacientes con EP y con CDM.

Effects of two different exercise programs on gait parameters in individuals with Parkinson's disease: a pilot study.

To date, little attempt has been made to compare or evaluate the effects of different physical exercise programs on gait disorders in people with Parkinson's disease (PD). This pilot study is aimed at obtaining preliminary data of the effects of two different exercise programs on gait parameters in people with PD by means of a biomechanical three-dimensional motion analysis. Twenty-five individuals with idiopathic PD participated either in a land-based (LB) or in a LB plus water-based (LWB) exercise program for 16 weeks. The efficacy of both exercise programs was quantified by means of a biomechanical gait analysis from which spatiotemporal and sagittal plane kinetic (gait speed, stride length, cadence, stride time, simple support time, double support time) and kinematic (angles of the hip, knee, and ankle joints) variables were recorded. Once the intervention ended, significant changes were observed in stride length and single/double support time variables in all the patients. The intergroup analysis revealed the existence of significant differences only in the gait Speed and hip Angle parameters. Few significant improvements in the amplitude of lower limb joints were found. These results suggest that land-based and land-plus-water-based exercise programs can be considered as a useful physical rehabilitation alternative, both equally capable of improving gait impairment on Parkinson's disease.

Análisis de la validez convergente de la Versión reducida en español del cuestionario de actividad física en el tiempo libre de Minnesota (VREM) y de la versión española del Cuestionario internacional de actividad física en personas mayores (IPAQ-E) / Analysis of the convergent validity of the Spanish short version of the Minnesota Leisure Time Physical Activity Questionnaire (VREM) and the Spanish version of the International Physical Activity Questionnaire in elderly people (IPAQ-E)

Fundamento: Los cuestionarios Versión reducida en español del cuestionario de actividad física en el tiempo libre de Minnesota (VREM) y Cuestionario internacional de actividad física adaptado a las personas mayores (IPAQ-E) se consideran herramientas de utilidad cuando se pretende cuantificar la actividad física (AF) que la población geriátrica realiza en nuestro país. Sin embargo, son escasos los estudios realizados al respecto de sus propiedades psicométricas. Por ello, esta investigación pretende aportar información sobre la validez convergente de ambos cuestionarios, analizando el grado de asociación que muestran con la condición física (CF). Material y Métodos: Un total de 105 personas (edad media: 76,77 (DE=6,01) años; 84,8% mujeres), contestaron ambos cuestionarios y realizaron la batería Senior Fitness Test (SFT) al objeto de recoger información sobre su nivel de CF. Resultados: Se encontraron correlaciones significativas entre la SFT y los ítems del VREM relativos al gasto energético derivado de caminar (r=0,227) o de realizar actividades deportivas o baile (r=0,235), y el gasto energético total estimado (r=0,314). El IPAQ-E no estableció asociaciones significativas con ninguna de las variables analizadas. Aunque a priori se observó una cierta correlación entre el VREM y el IPAQ-E (r=0,447, p<0,001), y la diferencia media entre ambos parámetros fue nula (p=0,553), se consideró que los cuestionarios mostraron un grado de concordancia escaso, debido a la gran amplitud encontrada en el rango de diferencias. Conclusiones: Se aconseja el empleo del cuestionario VREM para estimar la cantidad de AF en población geriátrica, ya que presenta cierto grado de asociación, si bien débil, con el nivel de CF

Conclusions: The use of the VREM questionnaire is recommended for estimating the amount of PA performed by the geriatric population, as it shows a certain degree of association, albeit weak, with the level of physical fitness

Lesiones deportivas en squash: estudio prospectivo en jugadores federados / Sports injuries in squash: Prospective study in federated players

Objetivo Analizar de manera prospectiva el patrón de lesión deportiva y su incidencia en función del tiempo de práctica, en una muestra de jugadores de squash de distinto nivel deportivo y de edad. Material y métodos Se realizó un estudio de cohortes prospectivo con jugadores de squash españoles que estuviesen federados y con ránking, durante la temporada 2018-2019. Se solicitó a los participantes que cubriesen un cuestionario «on line» cada vez que se registrase una lesión. Además, se registró el tiempo de entrenamiento y de competición de todos los jugadores, al objeto de establecer la incidencia lesional por cada 1.000h de práctica. Resultados Se obtuvo información de un total de 38 jugadores (17 veteranos, 13 senior y 8 sub-19). Se registraron un total de 22 lesiones, observándose que el 27,7, el 45,45 y el 27,27% de los jugadores veteranos, seniors y sub-19, respectivamente, reconocieron haberse lesionado durante la temporada. Ningún jugador se lesionó más de una vez. Las lesiones más habituales fueron las musculoesqueléticas y los miembros inferiores fueron la zona más frecuentemente afectada. La incidencia lesional fue de 1,41/1.000h. No se observó influencia del sexo o de la categoría en el riesgo de lesión. Conclusión La práctica del squash se puede considerar como potencialmente lesiva, dado que más de la mitad de los jugadores veteranos, senior y sub-19 se lesionan al menos una vez por temporada, con independencia de su edad, sexo o ránking.

Objective To prospectively analyse the pattern of sports injuries and their incidence as a function of practice time in a sample of squash players of different sporting levels and ages. Material and methods A prospective cohort study was carried out with Spanish squash players who were federated and ranked during the 2018-2019 season. Participants were asked to complete an online questionnaire each time they registered. In addition, the training and competition time of all players was also recorded in order to establish the injury incidence per 1000h of practice. Results Information was obtained from a total of 38 players (17 veterans, 13 seniors and 8 U19). A total of 22 injuries were recorded, with 27.7%, 45.45% and 27.27% of the veteran, senior and U19 players, respectively, acknowledging injuries during the season. No player was injured more than once. The most common injuries were musculoskeletal injuries, with the lower limbs being the most frequently affected area. The incidence of injury was 1.41/1000h. No influence of gender or category on injury risk was observed. Conclusion Squash can be considered as potentially injurious, given that more than half of the senior, senior and more than half of the veteran, senior and U19 players are injured at least once a season, regardless of at least once per season, irrespective of age, gender, or ranking.

Lesiones deportivas en squash: estudio prospectivo en jugadores federados / Sports injuries in squash: Prospective study in federated players

Objetivo Analizar de manera prospectiva el patrón de lesión deportiva y su incidencia en función del tiempo de práctica, en una muestra de jugadores de squash de distinto nivel deportivo y de edad. Material y métodos Se realizó un estudio de cohortes prospectivo con jugadores de squash españoles que estuviesen federados y con ránking, durante la temporada 2018-2019. Se solicitó a los participantes que cubriesen un cuestionario «on line» cada vez que se registrase una lesión. Además, se registró el tiempo de entrenamiento y de competición de todos los jugadores, al objeto de establecer la incidencia lesional por cada 1.000h de práctica.

Aplicación de ejercicios de Brain Gym(R) en personas institucionalizadas con deterioro cognitivo / Effects of Brain Gym(R) exercises in institutionalized older adults with cognitive impairment

Este estudio tuvo como objetivo comparar los efectos de un programa de ejercicios de Brain Gym(R) con un programa de gimnasia de mantenimiento en pacientes mayores institucionalizados con deterioro cognitivo. Veintinueve personas institucionalizadas con deterioro cognitivo participaron en dos programas, uno basado en ejercicios de Brain Gym(R) y otro de gimnasia de mantenimiento, durante 18 semanas. Se emplearon los test Mini-examen cognoscitivo, Fototest, Trail Making Test, Índice de Barthel y el Timed up and Go. No se encontraron mejoras significativas en las variables analizadas. Se observó una tendencia positiva, especialmente en el grupo de gimnasia de mantenimiento, en la función cognitiva global y salud física. En conclusión, los efectos de un programa de ejercicios de Brain Gym(R) en una muestra de personas mayores institucionalizadas con deterioro cognitivo fueron similares a los de un programa de gimnasia de mantenimiento, sin mejoras significativas de la función cognitiva o independencia funcional

This study aimed at comparing the effects of a program based on Brain Gym(R) exercises against a fitness exercise program on the cognitive function and functional independence in institutionalized older adults with cognitive impairment. Twenty-nine institutionalized older adults with cognitive impairment took part either on a Brain Gym(R) based exercise program or on a fitness exercise program during eighteen weeks. The assessment measures used were the Mini-Examen Cognoscitivo, Fototest, Trail making test, Barthel Index and the Timed up and Go Test. None of the variables analysed improved significantly. A trend towards improvement, particularly in the fitness exercise group, in both cognitive status and functional independence was observed. In conclusion, the performance of a Brain Gym(R) exercise-based program had the same effects than taking part in a fitness exercise program, with no significant improvements on the cognitive function or functional independence, in a sample of institutionalized older adults with cognitive impairment
