Never Too Late to Exercise: the PROOF Study

Even at older ages, exercise is a still very important - as demonstrated by the degree to which it influences ongoing health in later stages of life, just as it does in earlier stages in life. "It is not sufficient simply to live longer. One of the current priorities for public health is to how to maintain good quality of life for longer. This has given rise to the concept of 'successful aging' generating a turning point in our thinking about aging, which is no longer seen as an inevitable decline. ... Physical activity has a pleiotropic effect and is a significant factor in successful aging. This study aims to quantify the relationship between the physical activity of a 65-year-old cohort and the level of life satisfaction and self-rated health 7 years later. A total of 988 questionnaires were sent by mail to a representative sample of healthy pensioners. Life satisfaction and health status were estimated on two visual analogical scales in answer to the following questions: (1) How would you estimate your state of health? and (2) Are you generally satisfied with your life? The level of physical activity was estimated using a questionnaire which enabled us to calculate: Daily energy expenditure (DEE) [and] VO2 peak. ... Energy spent in activity and VO2 peak estimated from DEE, measured at the age of 65, appear to be strong predictors of well-being 7 years later."
