Fatigue has been associated with reductions in daily activity of older people. Summary measures of daily physical activity provide limited understanding of how fatigue affects physical activity behavior. This study examined the hour-by-hour energy expenditure estimated from accelerometry data to provide insight into physical activity behaviors of older people experiencing fatigue. Fatigued participants were matched to ‘not fatigued’ participants by age, sex, and BMI. Each group consisted of 86 people with a mean age 73.8 years (SD 2.0), BMI 26.5 kg⋅m–2 (SD 3.9) and 61% female. The phase-space plot, constructed to express rate of change of average vertical axis counts per hour as a time series, showed fatigued participants deviated from the not fatigued participants during the morning period, when hour-by-hour activity was increasing. Older people who feel fatigued have a different morning activity pattern, which appears to lead to the lower overall levels of physical activity.

The purpose of this study was to determine older adults’ physical activity behaviors and stage of readiness for physical activity. Data were collected on 403 American adults over the age of 60. Of these participants, 206 were aged 61–70 and 197 were over the age of 70. Participants first provided information regarding their perceptions of the benefits of physical activity. Then questions were asked to determine their stage of readiness for physical activity (i.e., precontemplation, contemplation, etc.). Results indicated that older adults are aware of the health benefits of physical activity (89%), but 69% of them are not participating in sufficient physical activity to obtain such benefits. Physical activity involvement decreases with increased age, and older men tend to be more physically active than older women. Increased knowledge about the benefits of physical activity and one’s stage of readiness for it might help increase the number of older adults who engage in sufficient physical activity.

, as children are more likely than college-aged adults to engage in physical activity as a form of play, investigating how these devices affect their physical activity behavior during unstructured play is warranted ( 10 , 12 , 14 ).

Positive youth development (PYD) is an emerging area of study and practice that targets fostering the assets of young people to avoid problem behaviors and excel in meeting diverse life challenges. This paper describes how PYD evolved from treating problem behaviors to preventing problem behaviors in at-risk youth, to more recently helping all youth thrive and excel in numerous domains. Although evidence to inform community policy and practice has emerged, there is a lack of consensus on how to define PYD, and this lack of consensus has impacted progress in PYD physical activity behavioral science. This paper recommends PYD physical activity behavioral science reject disciplinary boundaries and (a) examine the nature of person-environment interaction in the context of physical activity as the primary outcome, (b) target big-picture physical activity outcome questions, and (c) come to a consensus on the domains of physical activity behavioral science research competencies.
