Physical Activity Change in an RCT: Comparison of Measurement Methods

  • Published on May 7, 2019

Objectives We aimed to quantify the agreement between self-report, standard cut-point accelerometer, and machine learning accelerometer estimates of physical activity (PA), and examine how agreement changes over time among older adults in an intervention setting. Methods Data were from a randomized weight loss trial that encouraged increased PA among 333 postmenopausal ...

Cognitive Functioning as a Moderator in the Relationship Between the Perceived Neighborhood Physical Environment and Physical Activity in Belgian Older Adults

  • Published on May 4, 2019

Objective To investigate whether the relationship of neighborhood environmental factors with physical activity (PA) is moderated by cognitive functioning in Belgian older adults. Methods Seventy-one older adults completed validated questionnaires on PA and environmental perceptions, wore an accelerometer, and completed a computerized assessment of cognitive functioning. Moderated linear regression analyses ...

Physical Activity and Sedentary Behavior at the End of the Human Lifespan

  • Published on May 4, 2019

Abstract To objectively assess physical activity levels and sedentary behavior in a cohort of Spanish centenarians and their nonagenarian peers. Physical activity and sedentary behavior patterns were objectively measured by an ActiGraph GT3X accelerometer in centenarians (n = 18; 83% women; 100.8 ± 0.8 [100–103] years) and nonagenarians (n = 11; 91% women; 93.3 ± 2.5 [90–98] years). Centenarians showed less counts per ...

Inducing incentive sensitization of exercise reinforcement among adults who do not regularly exercise—A randomized controlled trial

  • Published on May 7, 2019

Background Increasing exercise reinforcement, or decreasing sedentary reinforcement, may reduce sedentary activity and promote habitual exercise. Repeated exposures to a reinforcer may increase its reinforcing value (i.e., incentive sensitization). It is not yet known whether incentive sensitization occurs for exercise or factors associated with incentive sensitization for exercise reinforcement. ...

Breast cancer survivors reduce accelerometer-measured sedentary time in an exercise intervention

  • Published on May 29, 2019

Purpose Cancer survivors are highly sedentary and have low physical activity. How physical activity interventions impact sedentary behavior remains unclear. This secondary analysis examined changes in sedentary behavior among breast cancer survivors participating in a physical activity intervention that significantly increased moderate-to-vigorous physical activity (MVPA). Methods Insufficiently active breast cancer ...

Energy Expenditure and Intensity of Group-Based High-Intensity Functional Training: A Brief Report

  • Published on May, 2019

Background High-intensity functional training (HIFT) may offer an attractive, time-efficient alternative to traditional aerobic exercise. However, limited information is available in the literature regarding HIFT meeting exercise guidelines for energy expenditure (improve health outcomes: ≥1000 kcal/wk; weight management: ≥2000 kcal/wk) and level of intensity (moderate: 3–6 metabolic equivalents [METs], vigorous: ≥6 METs) ...
