[en] 1.1 Introduction. Depression, anxiety, stress and sleep disturbances are very prevalent health problems today, and they are increasing even more due to the situation generated by the COVID-19 pandemic, its restrictive measures, its changes in lifestyle habits of the general population and other stressors. Therapeutic exercise and physical activity enhancement strategies have been shown to be effective tools to improve people's mental and physical health. 1.2 Objective: The main objective of this study is to test the effectiveness of an therapeutic exercise program as a tool to minimize the mental consequences of the pandemic in terms of symptoms of depression, anxiety, stress and sleep disturbances. In addition, secondary objectives are to improve the quality of life of the subjects and their physical health. 1.3 Methodology: To achieve the goals of the study, a randomized controlled clinical trial (RCT) blinded to third parties is proposed, with two groups: the intervention group will receive a 12-week intervention of combined ET (aerobic and strength – resistance) with 5 weekly sessions of 60 minutes, while the control group will not receive any treatment. Three evaluations will be carried out: baseline, post-intervention and follow-up. In each of them, depressive symptoms with the Beck Depression Inventory - Second Edition (BDI), anxiety with the State Trait Anxiety Inventory (STAI) and the Beck Anxiety Inventory (BAI), stress with the Perceived Stress Scale (PSS - 14), sleep quality with the Pittsburgh Sleep Quality Index (PSQI) will be assessed as main variables. In addition, quality of life will be secondarily assessed with The World Health Organization Quality of Life (WHOQOL- BREF) and some variables related to physical health and exercise.

[gl] 1.1 Introdución: A depresión, a ansiedade, o estrés e as alteracións do sono son problemas de saúde moi prevalecentes na actualidade e están a aumentar aínda máis debido á situación xerada pola pandemia de COVID - 19, ás súas medidas restritivas, aos seus cambios nos hábitos de vida da poboación xeral e outros factores estresantes. O exercicio terapéutico (ET) e as estratexias de aumento da actividade física (AF) demostráronse como ferramentas eficaces para mellorar a saúde mental e física das persoas. 1.2 Obxectivo: O obxectivo principal deste estudo é comprobar a eficacia dun programa de ET como ferramenta para minimizar as consecuencias mentais da pandemia en termos de síntomas de depresión, ansiedade, tensión e alteracións do sono. Ademais, como obxectivos secundarios atópanse mellorar a calidade de vida dos suxeitos e a súa saúde física. 1.3 Metodoloxía: Para cumprir cos obxectivos do estudo, proponse un ensaio clínico controlado aleatorizado (ECA) cego a terceiros, con dous grupos: o grupo intervención recibirá unha intervención de 12 semanas de ET combinado (aeróbico e forza – resistencia) con 5 sesións semanais de 60 minutos, mentres que o grupo control non recibirá ningún tratamento. Realizaranse tres avaliacións: basal, post – intervención e de seguimento. En cada unha delas, valoraranse como variables principais os síntomas depresivos co Beck Depression Inventory - Second Edition (BDI), a ansiedade co State Trait Anxiety Inventory (STAI e o Beck Anxiety Inventory (BAI), o estrés coa Perceived Stress Scale (PSS - 14) e a calidade do sono co Pittsburgh Sleep Quality Index (PSQI). Ademais de forma secundaria, avaliarase a calidade de vida mediante o "The World Health Organization Quality of Life" (WHOQOL- BREF) e no grupo intervención algunhas variables relacionadas coa saúde física e o exercicio.
