The purpose of this study was to (1) determine the physical activity levels of 9–11 year old children, and (2) compare the activity levels of children who commute to school by active and passive modes. 140 children aged 9–11 years (85 boys) were recruited from four urban Irish schools. Mode of commuting was assessed by questionnaire. Step counts were measured for 4 consecutive days. Mean daily step counts for the sample were 14386 ± 5634. Boys were significantly more active than girls (15857 ± 5482 vs. 12113 ± 5127 steps). Eighty-seven children (62.1%) traveled by car, 51 children (36.4%) walked to school, one child traveled by bus and one child cycled. Children who walked or cycled to school had higher daily step counts than those who traveled by passive modes (16118 ± 5757 vs. 13363 ± 5332 steps). Active commuting to school may therefore represent a worthwhile strategy for improving children’s physical activity levels.

Background: Although levels of physical activity (PA) have been researched, no information on how university students organize their PA across different life domains is available. The purpose of this study is to explore if and how students organize their PA across transport and recreational domains, and to identify the psychosocial factors related to these patterns. Methods: Students from 31 Irish universities completed a supervised online survey measuring participant characteristics, psychosocial factors, and PA. Two-step cluster analysis was used to identify specific PA patterns in students. Binary logistic regressions identified factors associated with cluster membership while controlling for age, sex, household income, and perceived travel time to a university. Results: Analysis was performed on 6951 students (50.7% male; 21.51 [5.55] y). One Low Active cluster emerged. Four clusters containing a form of PA emerged including Active Commuters, Active in University, Active Outside University, and High Active. Increases in motivation and planning improved the likelihood of students being categorized in a cluster containing PA. Conclusion: One size does not fit all when it comes to students PA engagement, with 5 patterns identified. Health professionals are advised to incorporate strategies for increasing students’ motivation, action planning, and coping planning into future PA promotion efforts.

Background: Time spent in university represents a period of transition and may be an appropriate time to promote physical activity among young adults. The aim of this study was to assess participation of university students in sport and physical activity in Ireland and to explore the association between physical activity and perceptions of overall health, mental health, and happiness. Methods: The Student Activity and Sport Study Ireland was a cross-sectional online survey among a representative sample (n = 8122) of university students in Ireland. Binary logistic regressions were performed to examine associations between self-reported physical activity and gender (predictor variables) and individual perceptions of overall health, mental health, and happiness (binary outcomes). Results: Only 64.3% of respondents met the recommended level of 150 minutes of moderate to vigorous physical activity per week with males significantly more active than females (72.1% vs 57.8% meeting guidelines). Those meeting physical activity guidelines were more likely to report greater overall health and higher mental health and happiness scores compared with their inactive peers. Conclusions: Active students enjoy better health (overall and mental) and are happier than their inactive peers. This provides a clear rationale for providing students with opportunities to be active at university. The data provide a baseline to monitor changes in physical activity patterns.

This study explored motives and barriers to physical activity (PA) among older adults of differing socioeconomic status (SES) utilizing a self-determination theory and self-efficacy theory framework. Focus groups (n = 4) were conducted with older adults (n = 28) from two SES groups, using thematic analysis to identify motives and barriers. Integrated and identified regulations and, to a lesser extent, intrinsic motives, were evident across SES groups. Verbal persuasion and affective and physiological states emerged as prominent efficacy sources regardless of SES. More barriers were reported by the low SES group, with health conditions, neighborhood safety, and PA guidelines knowledge emerging as most salient. Time emerged as a prominent barrier for the high SES group. Integrated and identified regulations should be fostered in future interventions and policy regardless of SES. Barriers to PA varied across SES groups; thus future interventions and policy should account for such differences.

Activity measurement using a uniaxial pedometer was validated against behavioral observation using the Children’s Activity Rating Scale (CARS) in 30 three- to four-year-old children in a nursery school setting. Correlations were calculated for individual children, whereas the relationship for the total group was investigated using multilevel linear regression. The mean counts for boys and girls for the Digiwalker™ were 66.8 (± 64.0) and 47.4 (± 61.3; p < .01) steps per 3 minutes, respectively, whereas the mean CARS scores for boys and girls were 1.8 (± 0.6) and 1.6 (± 0.6; p < .01), respectively. Within-child correlations for CARS versus Digiwalker counts ranged from 0.64 to 0.95 with a median value of 0.86, whereas the multilevel analysis provided strong evidence of a relationship between CARS and Digiwalker (all p < .001). Data from the current study show that gender differences in physical levels exist in very young children and support the utility of the Digiwalker pedometer for assessing physical activity in this age group.

Markers of inflammation are emerging as novel indices of cardiovascular risk. These markers have been shown to alter acutely after intense exercise; however, the effects of more moderate intensity exercise in healthy individuals is not known. Walking forms a cornerstone of physical activity promotion, so the inflammatory response to this exercise merits investigation. This study evaluated the effects of a 45-min walk on C-reactive protein (CRP) and interleukin 6 (IL-6), in sedentary, overweight men.
Fifteen men (49.7 ± 5.9 y) walked for 45 min at 60 to 70% of predicted maximum heart rate. Fasted blood samples were taken prior to and immediately 1 hr and 24 h post-walk.
IL-6 decreased from 1 h post-walk to 24 h post-walk (P < 0.01). No significant changes were observed in CRP.
These findings suggest that 45 min walking at 60 to 70% HRmax-p causes a decrease in IL-6 24 h post-exercise, but does not evoke a significant response in CRP levels.
