To evaluate the effects of a 12-week injury prevention program on the isokinetic performance of knee extensor and flexor muscles and postural control in young indoor soccer athletes. Twelve athletes (23.14 ± 4.37 years) were included and assessed before and after the intervention. Muscle strength was assessed using the isokinetic dynamometer (Biodex System Pro 4), and postural control was assessed using posturography dynamics (EquiTest® System) and sensory organization tests (TOS). This parameter was divided into six conditions that analyzed systems responsible for maintaining balance (visual, vestibular, and somatosensory). The isokinetic performance improved after the intervention, especially in peak torque and thallus flexors power, as well as postural control (TOS) in conditions III and VI. Thus, the improvement observed in these parameters after intervention may reduce the risk of lesions in indoor soccer athletes. [ABSTRACT FROM AUTHOR]

The aim of this study was to determine the sensitivity of different methods of partialization, in terms of different body component indices in relation to indicators of strength and explosiveness. The research involved 187 subjects who were divided into two groups based on sex. This research consisted of measuring body composition characteristics by multichannel bioimpedance analysis (BIA) InBody 720, as well as contractile characteristics of different muscle groups with tenziometric Dinamometry method. Based on the results of the factor analysis we found that regardless of the sex the most sensitive variable for partialization of absolute body isometric strength variable (ABiS) is partialization by allometric scaling (0.964 for females and 0.947 for males explained factor variance). However, in the case of absolute body isometric explosiveness (ABiE), the results of this study have demonstrated that partialization relative to skeletal muscle mass according to the body longitudinality – skeletal muscle mass index (SMMI) is the methodological choice disregarding the sex (0.982 for females and 0.980 for males explained factor variance). The results of the study have shown that for the purpose of scaling the maximal strength relative to body composition, the allometric method can be considered as a choice, while for the partialization of maximal isometric explosiveness skeletal muscle mass index is the best choice insensitive of the sex.

Introducción: la desnutrición (DN) en la persona mayor (PM) al ingreso hospi- talario alcanza el 60,00 %. Las hospitalizaciones de más de ocho días muestran una reducción significativa de la masa muscular (MM) y la fuerza muscular (FM). Objetivo: determinar el efecto de los primeros 10 días de hospitalización sobre la evolución de la MM, según la circunferencia de la pantorrilla (CP), la circunferencia muscular del brazo (CMB), el espesor del músculo aductor del pulgar (EMAP) y la FM. Métodos: estudio descriptivo y longi- tudinal. Los datos se obtuvieron mediante la Mini Nutritional Assessment (MNA) y las mediciones antropométricas (peso, talla, CP, CMB, EMAP y FM) se realizaron a las 24-48 horas del ingreso del paciente, y a los 10 días. Resultados: la muestra quedó conformada por 49 PM. Predominó el sexo feme- nino (57,00 %; n = 28). La media de edad fuede77±8,2años(IC:95%=75,2-80 años) y un rango de 65 a 96 años. El índice de masa corporal (IMC) promedio fue de 24,6 ± 4,3 kg/m2 (IC: 95 % = 23,4-25,8) y un rango de 17,3 a 34,6 kg/m2. La prevalencia de evolución desfavorable de la MM fue del 67,30 %, 55,10 % y 51,00 %, según CP, CMB y EMAP, respectivamente. Para la FM, la evolución favorable predominó en un 53,10 %. Conclusión: la hospitalización empeora la evolución de la MM, sin poder confirmar lo mismo para la FM. La MM, según el EMAP, fue la que presentó mayor dispersión.

Introducción: Los niños con Artritis Idiopática Juvenil (AIJ) experimentan períodos de dolor e inmovilidad que afectan sus capacidades condicionales. El objetivo del estudio fue describir los valores de referencia para el Sit to Stand Test de 1 minuto (1-STS) en niños con AIJ como evaluación de la fuerza muscular de los miembros inferiores (MMII). Materiales y Métodos: Se realizó un estudio observacional que incluyó a 15 niños con AIJ de entre 5 y 16 años. Se evaluó su rendimiento en el 1-STS. Resultados: Los niños con AIJ (n=15) realizaron 40,73±10 repeticiones en el 1-STS. Se encontró una correlación positiva significativa entre el 1-STS y el Test de la Marcha de 6 Minutos (r=0,58;p=0,02), como con el Índice de Capacidad Funcional (CAPFUN) (r=0,54;p=0,04). No se observaron correlaciones significativas entre el Childhood Health Assessment Questionnaire (CHAQ) y el 1-STS (r=-0,20;p=0,49), tampoco con el Juvenile Arthritis Disease Activity Score (JADAS) (p=0,82). Conclusiones: Los niños con AIJ presentaron valores de fuerza muscular en los MMII más bajos en comparación con niños sanos de la misma edad. El 1-STS parece prometedor para evaluar la debilidad muscular en esta población.

Introduction: in rugby, some muscle characteristics visible with ultrasound have been related to the risk of injury to the long head of the biceps femoris. However, scientific evidence is scarce. Objective: to evaluate the changes in the morphofunctional ultrasound characteristics of the long head of the biceps femoris in rugby players of a professional rugby team at the end of the season. Material and method: a prospective analytical observational study was carried out at the University of Alcalá, with 19 players belonging to the Rugby Division Honor B team. Three ultrasound measurements were taken, measuring muscle thickness, perimeter, cross-sectional area and penile angle using the free software Fiji/Image, contraction and relaxation speed with M-mode, and the strength of the quadriceps and hamstring with a dynamometer. Results: significant differences were evidenced in quadriceps and hamstring strength and relaxation speed, with large and medium and significant effect sizes. When comparing backs and forwards, a significant effect was found on quadriceps strength of both the playing position factor and the training factor. In hamstring strength there was only a significant effect of the training factor. Conclusions: the results obtained in this study reveal, on the one hand, the existence of statistically significant differences in the variables of muscle strength of the quadriceps and hamstrings and relaxation speed, as well as in the muscle strength of the quadriceps when comparing backs and forwards; and on the other hand, there could be a relationship between the variables of pennation angle and muscle strength with the reduction in the risk of injury, which could provide a boost towards new research in this field. Regarding inter- and intraobserver reliability, it was moderate to excellent. [ABSTRACT FROM AUTHOR]

Introduction: sarcopenia is characterized by loss of muscle mass and function. Spinal disorders are a risk factor for muscle deterioration. In turn, sarcopenia is associated with adverse outcomes in the postoperative period of spinal surgery. Objectives: to evaluate sarcopenia and the relationship of muscle strength with bioimpedance parameters in the preoperative consultation. Material and methods: cross-sectional observational study. Muscle strength (dynamometry) and body composition (bioimpedance spectroscopy) were measured as part of the functional assessment of nutritional status. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People 2019 (EGWSOP2) and dynapenia/myopenia in the case of low strength or isolated muscularity. The relationship between the dynamometry values and the bioimpedance variables was summarized with the Spearman's coefficient. Results: twenty-two patients were included. The median (IQR) age was 60 years (43-65) and 72 % were women. The most frequent diagnosis and surgical procedure was spondylolisthesis (45 %) and posterior fixation (50 %). The mean body mass index (BMI) was 28.3 (± 4.59) kg/m2. The presence of sarcopenia, dynapenia and myopenia was 18.2 %, 13.6 % and 22.7 %, respectively. Dynamometry was correlated with lean tissue index: 0.61 (p 0.002); body cell mass: 0.68 (p 0.000); appendicular skeletal muscle: 0.49 (p 0.021); phase angle: 0.46 (p 0.031); and resistance index 200/5 kHz: -0.47 (p 0.028). Conclusion: muscle strength is correlated with bioimpedance parameters. Sarcopenia, dynapenia and myopenia are frequent and objectifiable in the preoperative spinal surgery consultation.

Introducción: los niños con artritis idiopática juvenil (AIJ) experimentan períodos de dolor e inmovilidad que afectan sus capacidades condicionales. Objetivos: describir los valores de referencia para el 1-minute Sit-to-Stand Test (1-STS; test de 1 minuto de sentarse y pararse) en niños con AIJ como evaluación de la capacidad aeróbico-funcional y de la fuerza muscular de los miembros inferiores (MMII). Materiales y métodos: se realizó un estudio observacional que incluyó a 15 niños con AIJ de entre 5 y 16 años. Se evaluó su rendimiento en el 1-STS. Resultados: se encontró una correlación positiva significativa entre el 1-STS y el test de la marcha de 6 minutos (r=0,56; p=0,03), como con el índice de capacidad funcional (CAPFUN) (r=0,54; p=0,03). No se observaron correlaciones significativas entre el Childhood Health Assessment Questionnaire (CHAQ) y el 1-STS (r=-0,21; p=0,44), tampoco con el Juvenile Arthritis Disease Activity Score (JADAS-10) (p=0,83). Conclusiones: el 1-STS parece prometedor para medir la capacidad aeróbico-funcional y la fuerza muscular de los miembros inferiores en niños con AIJ oligoarticular.

Introducción: La sarcopenia aumenta el riesgo de caídas y fracturas, además de relacionarse con diversas enfermedades y aumento de la mortalidad. Distintos grupos de investigación proponen diferentes definiciones para el diagnóstico de sarcopenia, que incluyen la medición de la masa muscular por DEXA y la valoración de la fuerza de prensión palmar a través de un dinamómetro de mano. Sin embargo, estos 2 instrumentos no están habitualmente disponibles en los consultorios médicos. Objetivos: Determinar la utilidad diagnóstica de 2 pruebas de rendimiento físico: velocidad de marcha e incorporarse de una silla, como herramientas para la detección de pacientes con probable sarcopenia. Metodología: Se incluyeron 706 mujeres, entre 50 y 85 años, a las que se realizó las pruebas funcionales y DXA (n=376) para medir la masa muscular. Resultados: El 26,1% registró una velocidad de marcha disminuida mientras que el 55,3% presentó alteración en la realización de la prueba de incorporarse de una silla. La prevalencia de sarcopenia varió desde un 4,5% hasta un 35% según los criterios utilizados. Ambas pruebas presentaron un alto valor predictivo negativo (>70%) para el diagnóstico de sarcopenia, mientras que la prueba de incorporarse de una silla mostró además, una alta sensibilidad (> 66%) para dicho diagnóstico. Conclusión: La implementación en el consultorio de estas pruebas sencillas y sin costo, simplificaría la detección de pacientes con probable sarcopenia.

Desde hace poco, se han explorado otras moléculas que suponen resultados superiores, como el clorhidrato de creatina, que promete tener una mejor solubilidad y beneficios similares en el rendimiento deportivo y la composición corporal. Objetivo: presentar las diferencias entre creatinina monohidratada y clorhidrato de creatina en términos de solubilidad, rendimiento deportivo y composición corporal. Materiales y métodos: revisión de artículos científicos en humanos y animales, publicados entre el 2009 y el 2020. Resultados: en relación con la solubilidad y las propiedades químicas, el clorhidrato de creatina tiene mayor peso molecular, solubilidad, absorción y biodisponibilidad, y menor pH, efectos adversos y dosis para logar efectos ergogénicos que la creatina monohidrato. Respecto al rendimiento deportivo y composición corporal, ambas moléculas presentaron mejoras en el rendimiento y fuerza máxima. No todos los estudios mostraron disminución en la masa grasa para clorhidrato de creatina, la cual presentó menor retención intramuscular de agua. Conclusión: existe una tendencia a favor del clorhidrato de creatina respecto a la solubilidad y la composición corporal. No se encontró evidencia suficiente para concluir que sus efectos en el rendimiento deportivo, sobre todo en términos de fuerza, sean superiores a los del clorhidrato de creatina.
