Abstract
[Excerpt] A recent study examined the impact of TV viewing during exercise on observable volitional behavior (i.e. treadmill endurance time) among insufficiently active adults (46±15 years, 31±5 kg/m2 ; 68% women). Participants completed two visits in a randomized order, with >48H separating them. Participants could sit or walk on the treadmill (moderate intensity) as desired within a 60-minute time frame. During one visit, participants were able to view TV during exercise and while sitting. During the other, TV viewing was allowed only when seated. Despite the average participant accumulating 63±58 minutes of moderate-to- vigorous physical activity (MVPA) per week, 24% of participants walked continuously for 60-min at both visits.
