[Attentional focus instructions for therapeutic exercise in people with musculoskeletal disorders. A scoping review]. / Instrucciones con foco atencional durante el ejercicio terapéutico en personas con trastornos musculoesqueléticos. Una revisión de alcance.

Attentional focus instructions are verbal strategies that could maximize the effects of exercise. The objective of this review was to explore and synthesize the available evidence on the incorporation of attentional focus instruction in the exercise of people with musculoskeletal disorders. A search of 11 databases was carried out until October 2020. Of 4,227 studies identified in the searches, 15 were included. The studies showed deficiencies in the conceptualization and definition of attentional focus instructions. The available evidence indicates that external focus is effective in improving motor learning and function. However, methodological limitations, clinical heterogeneity, the small number of articles included, and new experimental studies challenge the conclusions of the systematic reviews available to date. Attentional focus instructions in musculoskeletal disorders is an emerging field and requires further research. This review is a guide for future studies.

[Blood flow restriction training for people with cardiovascular disease: An exploratory review]. / Entrenamiento con restricción parcial de flujo sanguíneo en personas con enfermedades cardiovasculares: una revisión exploratoria.

OBJECTIVE: To analyse the evidence on the effects of blood flow restriction training in people with cardiovascular disease. MATERIALS AND METHODS: We searched MEDLINE, EMBASE, SPORTDiscus, CINAHL, LILACS, SCOPUS and Wiley databases. Experimental and non-experimental studies investigating the effects of blood flow restriction in participants with cardiovascular disease were included. RESULTS: Six clinical trials and three non-experimental studies met the inclusion criteria. The experimental studies were conducted in participants with hypertension and ischaemic heart disease. Non-experimental studies described hemodynamic adaptations and potential adverse effects of therapy. The risk of bias of the included clinical trials was moderate to high. Exercise-induced hemodynamic stress increased significantly during training with blood flow restriction compared with traditional training. The small number of available studies have focused mostly on acute effects, but chronic effects are unknown. CONCLUSION: There is currently no evidence to recommend the use of blood flow restriction in people with cardiovascular disease.
