Experimental: Sedentary; usual, 25% reduced, 50% reduced
The initial 3 weeks of the study, children were asked to maintain their usual targeted sedentary behaviors (TV, video game, computer use) measured by a television reduction device (TV Allowance). The following 3 weeks children were asked to reduce their targeted sedentary behaviors (TV, video game, computer use) by 25% from the usual sedentary condition using a television reduction device (TV Allowance). The final 3 weeks of the study, children were asked to reduce their targeted sedentary behaviors (TV, video game, computer use) by 50% from the usual sedentary condition using a television reduction device (TV Allowance)
Device: Television reduction device
A TV allowance helps turn off the television when the time limits have been met.
- Physical Activity [ Time Frame: 3 days ]Actigraph activity monitors were used to record physical activity over 3 days, in addition to a weekly physical activity diary. Acti-graph counts were used to estimate energy expenditure during waking hours. Counts per minute describes the average rate of counts, with 0 being at rest and higher numbers indicating more vigorous physical activity.
- Energy Intake [ Time Frame: 3 days ]Resting metabolic rate was calculated using the activity data from accelerometer (Actigraph) collection. Resting metabolic rate was used to calculate estimated daily energy expenditure. Daily energy expenditure and weight change over the study period was used to estimate energy intake. If weight was stable of the nine weeks, assume energy intake = energy expenditure. A gain of a pound was estimated as equivalent to a positive balance of 3500 calories and a loss of a pound was estimated as equivalent to a negative balance of 3500 calories.
