    Efecto del entrenamiento con oclusión vascular sobre la potencia muscular en el ejercicio de press banca en adultos entrenados
    (Universidad de Murcia, Servicio de Publicaciones, 2023) Arenas-Sánchez, Giovanny; Mamani-Tapia, Braulio; Inostroza-Téllez, Eduardo; Peiret-Villacura, Luis; Farias-Valenzuela, Claudio; Orellana-Montini, Javier; Espinoza-Salinas, Alexis
    Introducción: El entrenamiento con oclusión vascular (EOV), combina ejercicio y reducción parcial del flujo sanguíneo con efectos positivos sobre el desarrollo de la hipertrofia muscular. Sin embargo, sigue habiendo una marcada inconsistencia en los efectos que genera sobre el desarrollo de la potencia muscular. Objetivo: Analizar el efecto del entrenamiento de oclusión vascular en la potencia muscular extremidades superiores de adultos entrenados. Métodos: Estudio cuasi-experimental la muestra la conformaron 12 sujetos, edad promedio 28 (± 1,3) años. Muestreo intencional, no probabilístico. Divididos en dos grupos; i) grupo intervenido (n=6), que realizó un protocolo de EOV al 30% de 1 repetición máxima (1RM); ii) grupo entrenamiento tradicional (n=6), realizó un entrenamiento al 70% de 1RM. Cada grupo realizó 12 sesiones de entrenamiento de press de banca. Resultados: El EOV, aumentó la potencia media (p =0,01); concéntrica (p = 0,04) y excéntrica (p =0,01). Conclusión: 12 sesiones de entrenamiento de fuerza muscular de baja carga con oclusión vascular mejoran de la potencia muscular de las extremidades superiores en el ejercicio de press banca en una muestra de adultos entrenados.

    The effect of Tabata exercises on muscle power and running speed in under-20 200 metres runners
    (Universidad de Murcia, Servicio de Publicaciones, 2022) Ali, Muntadher M.; Hussain, Ali Ab.; Jasim, Mokhalad M.
    The primary aim of the present study was to formulate a set of Tabata-style exercises and to identify the effect of these exercises for performance stages on power characteristic of speed and achievement of 200m for runners under 20 years old. The present study had an experimental pre-test & post-test design to solve the research problem of the study. 200-meter race runners were identified as the research community in Najaf Governorate for the 2020-2021 sports season. A total of 6 runners were selected as the participants for the study. The present study was conducted on 200m runners in the Najaf International Stadium, in Najaf governorate within the timeframe of June 2021 to September 2021. Based on the findings of the present study, the researchers concluded that the application of exercises in Tabata style aided in developing the power characteristic of speed for the two legs of the participants of the experimental group.

    Validity of an iPhone App to detect Prefrailty and Sarcopenia Syndromes in community-dwelling older adults: the protocol for a diagnostic accuracy study
    (MDPI, 2022-08-11) Montemurro, Alessio; Ruiz Cárdenas, Juan D.; Martínez García, María del Mar; Rodríguez Juan, Juan José; Fisioterapia
    Prefrailty and sarcopenia in combination are more predictive of mortality than either condition alone. Early detection of these syndromes determines the prognosis of health-related adverse events since both conditions can be reversed through appropriate interventions. Nowadays, there is a lack of cheap, portable, rapid, and easy-to-use tools for detecting prefrailty and sarcopenia in combination. The aim of this study is to validate an iPhone App to detect prefrailty and sarcopenia syndromes in community-dwelling older adults. A diagnostic test accuracy study will include at least 400 participants aged 60 or over without cognitive impairment and physical disability recruited from elderly social centers of Murcia (Spain). Sit-to-stand muscle power measured through a slow-motion video analysis mobile application will be considered as the index test in combination with muscle mass (calf circumference or upper mid-arm circumference). Frailty syndrome (Fried’s Phenotype) and sarcopenia (EWGSOP2) will both be considered as reference standards. Sensibility, specificity, positive and negative predictive values and likelihood ratios will be calculated as well as the area under the curve of the receiver operating characteristic. This mobile application will add the benefit for screening large populations in short time periods within a field-based setting, where space and technology are often constrained (NCT05148351).
