This study determined the validity and sensitivity of the SenseWear armband (SWA) during sedentary and light office duties compared with indirect calorimetry (IC).
Participants (N = 22), 30 to 64 years of age, randomly performed 6 conditions for 5 minutes each (ie, supine, sitting no movement, standing no movement, sitting office work, standing office work, walking at 1.0 mph). Steady state for each activity (ie, average for minutes 4 and 5) was analyzed.
Energy expenditure (EE) for the SWA (1.58 kcal/min) and the IC (1.64 kcal/min) were significantly correlated, r(20) = 0.90, P < .001 and ICC = 0.90, 95% CI (0.699, 0.966). Correlation results for each condition varied in strength, r(20) = 0.53 to 0.83 and ICC = 0.49 to 0.81, but were all significant (P < .05). A significant interaction between measurement method and condition existed (P < .001). The SWA under predicted EE during standing with no movement, sitting office work, and standing office work.
The SWA and IC EE rates were strongly correlated during sedentary and light activity office behaviors. However, the SWA may under predict EE during office work (standing or sitting) and when standing motionless, making it slightly less sensitive than IC.

The purpose of this study was to examine the correlates of physical activity (PA) with personal and environmental factors among people with disabilities in South Korea.
Data from the 2011 National Survey for Physical Activity and Exercise for the Disabled, conducted by Korea Sports Association for the Disabled, was used (n = 1478). The personal characteristics (age, gender, occupation, types of disabilities, family income) and the numbers of public PA-related facilities (welfare center, public indoor gym, and public outdoor facilities) and social sports/exercise clubs for people with disabilities across 16 local areas were also obtained. Hierarchical generalized linear model was used to examine subjectively measured PA in relation to personal and environmental factors.
The likelihood of engaging in PA was significantly lower for women with disabilities. People with hearing and intellectual disabilities were less likely to engage in PA compared with those with physical disabilities. The availability of sports/exercise clubs for people with disabilities was the only environmental factor that was significantly associated with PA.
These findings suggest the need of systematic intervention strategies based upon personal characteristics of people with disabilities. Further public efforts to promote sports/exercise club activities should be encouraged in this population.

The benefits of physical fitness are widely acknowledged and extend across many domains of wellness. The association between fitness and academic achievement, however, remains to be clarified, especially in young children. Therefore, the purpose of this study was to examine the relationship between fitness and academic achievement in elementary school children.
Data were collected from 134 third-, fourth-, and fifth-grade children. One-mile run time, body mass index, curl-up, and sit-and-reach data were collected from physical education instructors in Middle Tennessee. The percentage of questions answered correctly for the mathematics and reading/language arts sections of the Terra-Nova achievement test was taken as a measure of academic achievement.
A negative association (P < .01) was noted between 1-mile run times and mathematics scores (r = –.28), whereas a positive relationship (P < .05) was observed between muscular fitness and mathematics scores (r = .20). Relative to sex differences, inverse relationships (P < .05) were observed between 1-mile run times and reading/language arts and mathematics scores in girls (r = –.31 and –.36, respectively), but no significant associations were evident in boys.
Results from this study support a link between specific components of physical fitness and academic achievement in elementary school children.
