The purpose of this study was to investigate the potential long-term association of motor skill proficiency at 6 years of age and self-reported physical activity (PA) at age 26. Direct motor performance data were collected in 1991 with a follow-up study occurring in 1996, and then indirect questionnaires (self-report) administered in 2001 and 2011. In 2011, 17 participants who were identified as either having high motor proficiency (HMP) or low motor proficiency (LMP) in 1991 completed a series of 4 questionnaires. Analyses were conducted to determine whether there were differences between groups for motor skill proficiency, PA, or sedentary behavior, and whether these outcomes were related across ages. Motor skill proficiency at age 6 was related to self-reported proficiency at age 16 (r = .77, p = .006), and self-reported proficiency between 16 and 26 years (r = .85, p = .001). Motor skill proficiency at age 6 was positively associated with leisure time PA at age 26 in females and participants in the HMP group. The results may provide preliminary evidence about the importance of how early motor skill proficiency relates to long-term PA. More research with larger sample sizes is needed to investigate the importance of motor skills over time.

Sit-stand desks reduce workplace sitting time among healthy office workers; however, their metabolic and behavioral impact in higher risk populations remains unknown.
25 office workers with abdominal obesity were randomized to an intervention (sit-stand workstation) or control group (seated desk) for 12 weeks. Physical activity, sedentary behavior, and cardiometabolic risk factors were assessed before and after the intervention period in both groups.
In comparison with the control group, which did not change, the intervention group experienced significant reductions in workday (344 ± 107 to 186 ± 101 min/day) and total (645 ± 140 to 528 ± 91 min/day) sitting time, as well as increases in workday standing time (154 ± 108 to 301 ± 101 min/day, P < .05). There were no changes in sitting or standing time outside of work hours, steps taken each day, or any marker of cardiometabolic risk in either group (all P > .05).
Sit-stand desks were effective in reducing workplace sedentary behavior in an at-risk population, with no change in sedentary behavior or physical activity outside of work hours. However, these changes were not sufficient to improve markers of cardiometabolic risk in this population.
