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 ...
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. ...
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 ...
Abstract
This study describes and compares physical activity (PA) levels and sedentary time (ST) of active (AG) and a non-active (NAG) groups of adults with intellectual disability (ID) versus a group of adults without ID. Thirty-seven participants from the AG, 29 from the NAG, and 31 adults without ID participated in this ...
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) ...
Abstract
In objective physical activity (PA) measurements, applying wider frequency filters than the most commonly used ActiGraph (AG) filter may be beneficial when processing accelerometry data. However, the vulnerability of wider filters to noise has not been investigated previously. This study explored the effect of wider frequency filters on measurements ...
Abstract
Wearable accelerometers have recently become a standalone tool for the objective assessment of physical activity (PA). In free-living studies, accelerometers are placed by protocol on a pre-defined body location (e.g., non-dominant wrist). However, the protocol is not always followed, e.g., the sensor can be moved between wrists ...
Background
Levels of physical activity decline with age. Some of the most disadvantaged individuals in society, such as those with a lower rather than a higher socioeconomic position, are also the most inactive. Peer-led physical activity interventions may offer a model to increase physical activity in these older adults and ...
Background
ActiGraph accelerometers are a widely used tool to objectively measure physical activity (PA) behavior in young children and several validated cut-point sets exist to estimate time spent in different PA intensities (sedentary time, light PA, moderate-to-vigorous PA). Applying different cut-point sets leads to large and meaningful differences in results. ...
Abstract
The aim of the present study was to examine the associations of physical fitness, sedentary time, and physical activity (PA) with working memory and neuroelectric activity in children with overweight/obesity. Seventy‐nine children with overweight/obesity (10.2 ± 1.1 years old) participated in this cross‐sectional study. We assessed physical fitness ...
