El presente artículo analiza la trayectoria de la FORA en la ciudad de Buenos Aires durante la década del treinta, prestando atención a las transformaciones y limitaciones que esta organización sindical de orientación anarquista tuvo que enfrentar en una etapa de importantes desafíos para el movimiento obrero y las izquierdas. La indagación reconstruye las preocupaciones políticas esgrimidas por la FORA, sus intervenciones sociales y las áreas económicas donde sus sindicatos continuaron teniendo influencia. A su vez, el trabajo explora en los límites que condicionaron la proyección de esta organización, tanto en los ejes externos, reflejados en el contexto reaccionario y la mayor intervención del Estado en materia laboral; como en los factores internos, que derivaron en fuertes disputas al interior del anarquismo y la creación de nuevas organizaciones al margen de la tradicional federación obrera. A través de estos ejes se presta atención a las propuestas desarrolladas por los libertarios para revertir los condicionantes instaurados en aquellos años y la reconfiguración ocurrida dentro del movimiento obrero y del anarquismo porteño. Para este estudio se utilizó un variado corpus documental que incluye fuentes estatales, prensa comercial, archivos sindicales y periódicos anarquistas de diferentes tendencias.

The practice of physical exercise (PE), especially strength training (ST), has health benefits in the healthy population; however, the literature is scarce in the recommendations related to the population with intellectual disability (ID). This study represents the first analysis on the topic and aims to examine the structure and efficacy of ST experimental intervention programs in individuals with ID. This systematic review was carried out between January and April 2021, using the PubMed, Web of Science, Scopus, and SPORTDiscus databases, according to the PRISMA guidelines. From a total of 166 studies, eight were included in the present systematic review. The studies included a total of 280 individuals (18.23 ± 2.86 years old). The main features of the exercise programs are: 12 weeks average duration, three weekly sessions of 45–60 min, six to seven exercises targeting the main muscle groups, two to three sets, 6–12 repetitions, and avoiding free weights for safety reasons. The main results showed increments in strength, balance and fat-free mass and decrements in fat mass and waist circumference. It is a useful guideline for PE technicians to prescribe and adjust correctly in order to not only promote physical fitness, but improve the quality of life of individuals with ID.

Objectives: This study aimed to examine the relationship between age, body mass index, muscle strength, and balance in physically active, aged adults. Methods: Eighty-five participants were recruited for this study, having an average age of 70.31 years (SD = 9.90), ranging from 50 to 92 years. Twenty-six (30.6%) participants were male and fifty-nine (69.4%) were female. The participants had an average body mass index of 27.30 kg/m2 (SD = 3.62), ranging from 20.32 to 38.58 kg/m2. Participants undertook the Timed-Up and Go to test balance, and the chair-stand test to assess lower body strength. Hierarchical regression analyses were conducted. Three models (Model 1, 2, and 3) were tested to assess their relationships with balance: M1—Lower body muscle strength; M2—Lower body muscle strength and body mass index; M3—Lower body muscle strength, body mass index, and age. Results: All hierarchical models displayed significant variance. The third model explained 50.9% of the variance in dynamic balance, [F(3, 81) = 27.94, p < 0.001, R = 0.71, Ra2 = 0.51]. The difference in Ra2 between the first, second, and third models was statistically significant (p < 0.05). Age, body mass index, and lower body muscle strength had significant (p < 0.05) correlations with balance. In terms of the significant impact of each predictor, age had the strongest association with balance (p < 0.05). Conclusions: The results are useful to understand mechanisms or diagnose people at risk of fall.
