Associations between Physical Activity Dose and Health-Related Quality of Life

Abstract

Persons achieving recommended levels of PA were more likely to report fewer unhealthy days compared with inactive and insufficiently active persons; however, participation in daily moderate or vigorous PA and participation in very short (< 20 min x d) or extended ( > or = 90 min x d) periods of PA was associated with poorer HRQOL. Further research examining the relationship between the dose of PA and HRQOL as well as other health outcomes is needed.

Health-related quality of life, BMI and physical activity among US adults (⩾18 years): National Physical Activity and Weight Loss Survey, 2002

“…Our finding that inactive respondents were three times more likely to report X14 activity limitation days (OR ¼ 3.00, (95% CI 2.26, 3.99)) than those who were physically active were similar to results of a recent study based on 2001 BRFSS data, which showed them to be two times more likely to report 14 or more unhealthy days (OR ¼ 2.02, (95% CI 1.85, 2.21)). 2 Similarly, a systematic review of PA effects on quality of life 3 found that low levels of PA were related to poor physical function and disability.

“…HRQOL has been defined as an individual's or group's perceived physical and mental health over time. 1 Results of previous studies 2,3 have shown that PA is associated with a better quality of life, a lower mortality rate 4,5 and less risk of developing chronic disease. 6 Because physical inactivity is an important contributor to overweight and obesity, 7 the promotion of regular activity helps reduce people's risk for health problems related to overweight and obesity as well as those related to inactivity.…”

“…15,16 The dose-response effects of PA on HRQOL has been previously reviewed by Spriduso and Cronin, 3 who found that participation in PA enhanced well-being and physical function among adults 65 years or older. In a descriptive analysis, Brown et al 2 examined the relationship between the dose of PA and HRQOL among subjects stratified by age group and sex, and found that, in all strata, subjects who reported being regularly active were likely to have fewer unhealthy days than those who were inactive. Only two studies evaluated the association between PA and HRQOL, but BMI was not included as a covariate in either study.…”

“…Only two studies evaluated the association between PA and HRQOL, but BMI was not included as a covariate in either study. 2,3 The effect of BMI on the association between PA and HRQOL is not well understood, and it is possible that BMI may account for the inverse relationship between PA and health. Using a random sample of adults throughout the US, we examined the relationship between non-occupational PA and HRQOL, and evaluated the extent to which BMI serves as an effect modifier of that relationship.…”

Avaliação da qualidade de vida e do sono de atletas paralímpicos brasileiros

“…No entanto, grandes volumes de treinamento físico podem acarretar em alterações negativas, principalmente devido à relação entre o desgaste físico e psicológico que ocorre com o treinamento/competições comparado ao tempo que o atleta tem ou consegue descansar. Dessa forma, o volume de treinamento pode apresentar uma relação dose-resposta negativa entre nível de atividade física e qualidade de vida 10,11 . Em adição, já é demonstrado na literatura que a qualidade do sono está intrinsecamente ligada à QV, onde alterações no seu padrão normal podem levar a prejuízos físicos e psicológicos na saúde 12 .…”
