Background: Ageing and sedentary lifestyles affect physical and cognitive function and markers of frailty, increasing the risk of falls in older adults and affecting their quality of life. The aim of this study was to evaluate the effects of a Square Step Exercise programme on physical and cognitive function and plasma SMP30 levels for the prevention of falls in older adults. Methods: A randomised controlled trial was designed with 44 participants assigned to an experimental group (SSE group) and a control group. The SSE group performed SSE sessions twice a week for three months, with a follow-up in the fourth month. The assessments of physical function included tests such as the Four-Square Step Test, Brisk Walking and its dual-task variant, Time Up and Go and its imagined and dual-task variants, 30 s Sit-to-Stand and its dual-task and imagined variants and a 6 min walking test. Questionnaires were also used to assess the risk and fear of falling. Resting EEG activity was also recorded to assess electrocortical brain activity. SMP30 levels were measured by Western blotting. Results: The SSE group showed significant improvements compared to the control group in the Four-Square Step Test (p < 0.001), Brisk Walking (p < 0.05) and reduction in the fear of falling (p < 0.001) after the training programme, but these adaptations were not maintained one month after the programme ended (p < 0.05). No significant changes were observed in the remaining variables of physical function, cognitive function, fall risk questionnaire, EEG activity or plasma levels of SMP30 compared to the control group (p > 0.05). Conclusions: The SSE programme showed efficacy in improving balance, gait speed and reducing fear of falling in older adults but did not show improvement over the control group in other areas of physical or cognitive function or plasma SMP30 levels for fall prevention.

Motor imagery is often used as a training method to improve physical performance. Previous studies have often reported that reduced motor imagery is more likely to occur in older adults and stroke patients. However, it has also been reported that it is difficult to imagine exercises that cannot be performed. Therefore, we hypothesized that this may also have occurred in young people who were physically able to exercise but who were restricted by COVID-19 lockdowns, however, we could find no studies that investigated the impact of restricting outings. In this study, 83 healthy young people were measured for physical performance (maximum walking speed, grasp strength, Timed Up and Go test, imagined Timed Up and Go test, functional reach test, and five chair stand test). It was found that, while restricting outings did not influence physical performance in the subjects, it did influence motor imagery. Therefore, it should be borne in mind that training with motor imagery may not generate adequate actual motor imagery when restrictions are imposed on activities. Full article

Using available empirical data of Oromo Orature, particularly folksongs, obtained from the field through interview and observation in Oromia, central Ethiopia, in 2009 and 2010, and other sources in print, this study has two objectives to tackle. First, reflecting upon the questions of a native model of origin narratives in relation to ecology, this study examines some examples of Oromo ecopoetics to determine: (a) how ecology and creative process conspire in the production of folksongs and performance, and (b) how the veil of nature hidden in the opacity of songs is revealed through the rites of creative process and performance as the human and ecological realms intersect. When put in relation to ecology, I theorize, the ecocultural creative act and process go beyond the mundane life activities to determine the people’s use (of nature), perceptions, and implications. Second, damages to the ecology are, I posit, damages to ecoculture. Drawing on the notion of ecological archetypes, thus, the study makes an attempt to find a common ground between the idea of recurrent ecological motifs in Oromo orature and the people’s ecological identity. The findings show that the political and social attitudes the Oromo songs embody are critical of authorities and the injustices authorities inflict on peoples and the environment they live in. For the folksinger, singing folksongs is a form of life, and through performance, both the performance and the song sustain the test of time. In its language, critique, imagination, and cultural referents, Oromo Orature is a voice of the people who rely on traditional agricultural life close to nature along with facing challenges of the dominating religious, political and scientific cultures.
