Recess offers primary school age children the opportunity to engage in physical activity, though few studies have detailed the physical activity levels of children in this environment. The physical activity levels of 270 children ages 6-11 years from 18 schools were monitored on 1 school day using heart rate telemetry. Data revealed that boys engaged in higher levels of moderate-to-vigorous and vigorous physical activity (MVPA) than did girls during recess (26 and 20 min, respectively). These results suggest that recess can make a worthwhile contribution to the recommended 60 min of MVPA per day.

Physical inactivity is now a public health priority because of the high rates of inactivity observed worldwide. Achievement of physical activity guidelines could be attained with vigorous, moderate, or both activities combined. Our aim was to explore the prevalence and correlates of compliance with vigorous physical activity guidelines (CVAG).
Cross-sectional population-based survey in Pelotas, a southern Brazilian city, including 3182 adults (≥ 20 years). The short version of the International Physical Activity Questionnaire was applied by face-to-face interviews. CVAG was defined as at least 60 min/wk of vigorous activity.
Only 29% of the subjects achieved the vigorous activity threshold. Women, older adults, individuals with low BMI (< 18.5 kg/m2) or obese (≥ 30 kg/m2) were less likely to present CVAG. Compliance with moderate activity guidelines was associated with a higher likelihood of CVAG.
Concurrent promotion of moderate and vigorous physical activities is warranted in terms of public health.

Peak cardiorespiratory responses, physical activity patterns, and the association of VO2peak and physical activity were examined in 16 elementary (ES) and 16 high school (HS) females. Peak responses were assessed during treadmill running, and physical activity patterns were examined over two 12-hour weekdays. Results indicated similar relative VO2peak responses between groups (ES: M = 46.8 ml · kg−1 · min−1;HS:M = 46.6 ml · kg−1 · min−1). No statistical differences (p ≤ .05) were noted when moderate to vigorous physical activity (MVPA) and vigorous physical activity (VPA) were compared. Also, a three-way (Group × HR level × Sustained minutes) ANOVA revealed no statistical differences. A median correlation (r = .27) was found from 8 independent correlations of habitual physical activity and VO2peak. ES and HS appeared similar in regard to VO2peak, accumulative and sustained MVPA and VPA. Low levels of sustained MVPA and VPA (≥ 10 min) were evident in both groups.

The purpose of this study was to compare physical activity levels between white and South Asian children in the UK. The data were obtained from 606, 11–14 year old schoolchildren (397 white; 209 Asian). Physical activity was assessed using the ‘four by one day’ recall questionnaire from which the time spent in moderate and vigorous physical activity was calculated. Boys were significantly more active than girls (p = .0001), and white children reported significantly greater physical activity than south Asian children (p = .001). Mean ± SD of time spent in moderate and vigorous activity was 90.2 ± 65.4 mins and 68.2 ± 49.3 mins for white and south Asian children and 103.5 ± 63.4 mins and 65.6 ± 53.5 mins for boys and girls respectively. These findings indicate that south Asian children are significantly less active than their white peers and there may be a need for specific interventions to target South Asian children particularly.

Objective: To analyze the scientific evidence on the association of physical activity with urinary incontinence in older women. Design: Searches were performed in MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, and ScienceDirect. Observational studies were included. The following search terms were used: urinary incontinence, older adult, and physical activity. Methodological quality was assessed using the checklist proposed by Downs and Black. Results: Ten articles were included. Sedentary lifestyle and <150 min/week of physical activity are at risk of developing urinary incontinence. Walking (at least 30 min) and physical activities (600–1,500 and 600 METs/min per week) prevent urinary incontinence. Seven of the 10 studies indicated a good level of methodological quality. Conclusions: Sedentary lifestyle is at risk of urinary incontinence, and walking, moderate and vigorous physical activities are associated with prevention of urinary incontinence.

Participation in physical activity declines with advancing age for a variety of reasons. The aim of this study was to assess the level of physical activity among older South Australians. Computer-aided telephone interviewing of 773 adults age 60 years and over was conducted using random-digit dialing. Rates of participation among adults age 60 years and over in walking and vigorous physical activity (68.1% and 11.7%, respectively) were significantly lower than for those age 18–59 years (77.6% and 38.9%, respectively). Walking was the most popular activity among those age 60 and over. The proportion reporting no physical activity rose from 7.0% in the 60- to 64-year age group to 25.7% in the 85+ group. The findings describe increases in physical inactivity coupled with declines in functional ability with advancing age and suggest that much work remains to fully understand how best to encourage older adults to remain physically active.

Occupational disability was investigated in former Finnish athletes in the Olympic Games, World or European championships, or intercountry competitions during 1920–1965 (N = 2,402 men) for eight selected sports. The referents were 1,712 men selected from the Finnish conscription register, matched on age and area of residence and classified as completely healthy. The first outcome measure was the length of working life based on the age when the subject was granted a disability pension, or age at death before age 65. The Kaplan-Meier estimate of mean working life expectancy was 61.4 years for endurance sport athletes, 60.0 years for team games athletes, and 59.2 years for power sport competitors, compared with 57.6 years for the reference group. Decreased coronary artery disease and cerebrovascular and respiratory morbidity were observed for all athletes when compared with the referent group. It was concluded that sustained and vigorous physical activity during early adulthood may extend the occupationally active life span and defer the onset of disability before retirement age.

The primary purpose of this investigation was to examine the frequency and type of self-reported physical activity behavior in postsecondary students with reference to Healthy Campus 2010 objectives. The secondary purpose was to explore the role of information provision in terms of promoting physical activity behavior in postsecondary students.
Postsecondary students were assessed (N = 127360). Employing a trend survey design, the frequency and type of physical activity behavior was assessed along with physical activity/fitness information provision across a five year period between 2000 to 2004.
In 2004, respondents meeting Healthy Campus 2010 objectives for self-reported moderate and vigorous physical activity (MVPA) was 42.20% (95% CI = 41.75 to 42.65) and 48.60% (95% CI = 48.14 to 49.06) for strength (STRENGTH) training behavior. Progress quotients demonstrated that 12.93% and 7.87% of target objective for MVPA and STRENGTH respectively had been achieved from baseline. Those who received information reported engaging in more frequent physical activity behavior compared with those who did not (P < .001).
Results suggest the need for continued commitment to increasing physical activity behavior. The provision of physical activity/fitness information may be one mechanism through which this can be achieved.

Correlates of prenatal physical activity can inform interventions, but are not well-understood.
Participants in the Pregnancy, Infection, and Nutrition 3 Study were recruited before 20 weeks gestation. Women self-reported frequency, duration, and mode of moderate and vigorous physical activities. We used logistic regression to identify correlates of any physical activity (≥10 minutes/week of any mode), any recreational activity (≥10 minutes/week), and high volume recreational activity (either ≥150 minutes/week of moderate or ≥75 minutes/week of vigorous). Our analysis included 1752 women at 19-weeks gestation and 1722 at 29 weeks.
Higher education, white race, and enjoyment of physical activity were positively correlated with all 3 outcomes. Any recreational activity was negatively associated with parity, body mass index, and history of miscarriage. The associations of history of miscarriage and body mass index differed at 19 weeks compared with 29 weeks. Single marital status, health professional physical activity advice, and time for activity were associated with high volume recreational activity only.
Correlates of physical activity differed by mode and volume of activity and by gestational age. This suggests that researchers planning physical activity interventions should consider the mode and amount of activity and the gestational age of the participants.

Several methods exist to asses and control physical intensity levels of subjects engaged in physical activities programs, accelerometry is a method that could be easily used in the field. The purposes were: to calibrate Actigraph in middle-aged to old obese/overweight and DM2 adult patients; and to determine the threshold counts for sedentary, light, moderate, and vigorous physical activity (PA).
Sample comprise 26 participants (62.6 ± 6.5 years of age) of both gender. Counts and VO2 were simultaneously assessed during: resting, seating, standing, walking at 2.5 km·h−1, 5 km·h−1, and 6 km·h−1. A hierarchical linear model was used to derive a regression equation between MET and counts. Receiver operating characteristics (ROC) analysis was used to define thresholds for PA levels.
The regression equation was: MET = 1.388400490262 + 0.001312683420044 (counts·min−1), r = .867. The threshold counts for sedentary-light, light-moderate and moderate-vigorous PA were: 200, 1240, 2400 counts·min−1 respectively.
The Actigraph is a valid and useful device for the assessment of the amount of time spent in each PA intensity levels in obese/overweight and DM2 middle-aged to old adult patients.
