Only 19% of Australian youth participate in the recommended 60 minutes of daily moderate to vigorous physical activity (MVPA) ( 1 ), despite the importance of physical activity (PA) being widely acknowledged. Estimates fluctuate from 36% (5- to 8-y-old boys) to 6% (15- to 17-y-old girls) of youth

Research has shown that decreases in health-related fitness (fitness) may increase school absenteeism. 1 , 2 The fitness-physical activity association is well established, 3 including an improved cardiometabolic risk profile in youth who engage in moderate to vigorous physical activity daily. 4

Approximately three quarters of the children between 6 and 17 years of age are not meeting the recommended physical activity requirements of 60 min of moderate to vigorous physical activity (MVPA) per day ( Child & Adolescent Health Measurement Initiative, 2016 ). These low physical activity rates

understand whether, and to what extent, the effects of parental stress and family communication on adolescents’ PA varies by gender, particularly among Hispanic youth. Therefore, the objective of this study is to examine: (1) the relationship between parental stress and adolescents’ moderate to vigorous

This study examined associations between perceived neighborhood environment and physical activity among frail older adults and whether these associations are moderated by fear of falling. Participants were 238 frail older adults. Daily step counts and duration of moderate-to-vigorous physical activity were measured using an accelerometer. Participants completed the abbreviated Neighborhood Environment Walkability Scale; fear of falling and demographic and health-related factors were measured by a questionnaire. The interaction between crime safety and fear of falling was significantly associated with step count (p = .009) and moderate-to-vigorous physical activity (p = .018) in multiple regression analysis. Stratified according to fear of falling, crime safety was significantly associated with steps (p = .007) and moderate-to-vigorous physical activity (p = .030) in the low fear of falling group. The results suggest that crime safety is associated with physical activity among frail older adults, and this association is moderated by fear of falling.

The purpose of this study was to examine the relationships between physical activity and physical fitness and adiposity in a sample of 77 girls, aged 10–11 years. Physical activity was assessed by 7-day physical activity recall by which children reported how much time they spent on low and moderate-to-vigorous physical activities. Physical fitness was measured by EUROFIT test battery. Adiposity was estimated by sum of five skinfolds. The main finding of the study was that moderate-to-vigorous physical activity and adiposity were significant predictors (with 16–34% accounted variance) of physical fitness tests where the body mass affects performance. Indicators of physical activity and adiposity were not significantly related with fitness items requiring muscular strength, balance, flexibility, and speed of limb movement. Furthermore, moderate-to-vigorous physical activity and aerobic fitness predicted 22% of variance in adiposity in girls.

The main goal of the current study was to compare physical activity levels during swimming and nonswimming elementary physical education classes. We conducted a preliminary study and found that the System for Observing Fitness Instruction Time (SOFIT) could be used to register physical activity engagement levels in swimming classes. Thirty-nine classes, involving 8- to 12-year olds, participated in one swimming and one nonswimming physical education class. Classes were videotaped and physical activity levels for 234 students were quantified using SOFIT. Students engaged in more moderate-to-vigorous physical activity during swimming classes than during nonswimming classes. As a consequence, we advocate the inclusion of swimming lessons in physical education. Because the average engagement in moderate-to-vigorous physical activity was lower than the recommended 50% in 41% of swimming classes and in 77% of the nonswimming classes, however, comprehensive efforts are needed to increase physical activity levels during both types of elementary physical education classes.

Background:

Physical activity is important for maintaining independence and quality of life in older people living in care homes. Little is known about patterns of physical activity or sedentary behavior in this population.

Methods:

Thirty-three care home residents (82.6 ± 9.2 years) wore an ActiGraph GTX3 accelerometer for seven days, which provided minutes of sedentary behavior and low, light, and moderate-to-vigorous physical activity. Participants undertook the Mini-Mental State Examination and care staff reported activities of daily living (Barthel index) and functional ambulation classification (FAC) for each participant.

Results:

Participants spent on average 79% of their day sedentary, 14% in low, 6% in light, and 1% in moderate-to-vigorous physical activity. Activity levels did not significantly differ between days or hours of the day (P > .05).

Conclusion:

Levels of physical activity were very low and time being sedentary was high. This study can inform physical activity and sedentary behavior interventions for care homes’ residents.
