Resumo
Introdução: indivíduos com doença pulmonar obstrutiva crônica (DPOC) apresentam qualidade de vida reduzida e alta prevalência de ansiedade e depressão. Considerando que o exercício físico aumenta a percepção de felicidade em indivíduos saudáveis, a hipótese deste estudo é de que o treinamento físico pode melhorar a percepção de felicidade em indivíduos com DPOC. Objetivo: avaliar os efeitos do treinamento físico, em comparação com o cuidado clínico, na percepção de felicidade de indivíduos com DPOC. Métodos: ensaio clínico randomizado controlado, com alocação cega com proporção 1:1 e análise por intenção de tratar realizado com participantes com DPOC. O grupo controle receberá o cuidado clínico usual. O grupo intervenção receberá o cuidado usual mais um programa de treinamento físico de oito semanas (três sessões semanais). O programa incluirá 30 minutos de exercício aeróbico (esteira ou cicloergômetro) e exercícios resistidos. Desfecho primário: felicidade (Escala de Felicidade Subjetiva e Escala de Cantril). Desfechos secundários: escala de satisfação com a vida, força muscular periférica (preensão manual e teste senta e levanta de 30 segundos), capacidade funcional (teste de caminhada de seis minutos e teste Timed Up and Go), dispneia (escala modificada do MRC), fadiga (Escala de Fadiga de Manchester), qualidade de vida (Saint George’s Respiratory Questionnaire), ansiedade e depressão (Escala Hospitalar de Ansiedade e Depressão). Discussão: este será o primeiro estudo a avaliar o impacto do treinamento físico na felicidade de indivíduos com DPOC. O construto felicidade ainda não foi explorado no contexto da reabilitação pulmonar, o que pode ampliar a compreensão dos seus múltiplos benefícios.

Abstract
Background: individuals with chronic obstructive pulmonary disease (COPD) exhibit reduced quality of life and a high prevalence of anxiety and depression. Given that physical exercise enhances the perception of happiness in healthy individuals, this study hypothesizes that physical training could improve happiness in individuals with COPD. Aim: to evaluate the effects of physical training, compared to usual care, on the perception of happiness in individuals with COPD. Methods: a two-group, parallel, randomized controlled trial with allocation concealment in a 1:1 ratio and intention-to-treat analysis. The control group will receive usual clinical care. The intervention group will receive usual care plus an eight-week physical training program (three weekly sessions over eight weeks). The program will include 30 minutes of aerobic training (treadmill or cycle ergometer) and resistance training. The primary outcome is happiness (Subjective Happiness Scale and the Cantril Ladder Scale). Secondary outcomes: Life satisfaction (Life Satisfaction Scale), peripheral muscle strength (handgrip strength and 30-second sit-to-stand test), functional capacity (six-minute walk test and Timed Up and Go test), dyspnea (modified MRC scale), fatigue (Manchester COPD Fatigue Scale), quality of life (Saint George’s Respiratory Questionnaire), anxiety and depression (Hospital Anxiety and Depression Scale). Discussion: this study will be the first to assess the impact of physical training on happiness in individuals with COPD. The construct of happiness has not yet been explored in the context of pulmonary rehabilitation, which could enhance the understanding of its multiple benefits.
