The observed gains in LPA are important as there is growing evidence to suggest that increasing LPA and decreasing sedentary time provides health benefits independent of the amount of MVPA performed. Potential benefits include reduced metabolic risk, attenuation of arterial stiffening in old age, a reduced risk of hospital admission for COPD, a delay in the onset of frailty for older adults, and decreased risk of mortality. The volume of LPA required to accrue health benefits is not known, but there is evidence to suggest that replacing 30 minutes of sedentary time with 30 minutes of LPA has the potential to improve physical health as indicated by body mass index, number of health conditions, number of medications, and general health rating. While the self-efficacy enhancing intervention was successful compared with health education, it is not clear that the observed increase in LPA was clinically meaningful even if it were sustained. The ultimate challenge is to change habits and establish an increase in LPA that is maintained over multiple years.
