Benefits of replacing sitting time with activities


Researchers wanted to uncover what, if any, the benefits of replacing sitting time with exercise and activities were.

Why is this important?

The effects of replacing time spent with other activities has not been explored.

What was done?

A survey of over 300,000 older adults was administered, identifying how much time individuals spent sitting and in exercise and other activities.

What was found?

Increased time spent sitting was associated with increased risk of death. Replacing sitting time with activities, especially purposeful exercise, decreased the risk of death.

How does this effect me?

Increase your chances of living longer by avoiding sitting and replacing this time with activities. For example, instead of watching an extra episode on TV, go for a walk.

Article Abstract
It has been suggested that video game training enhances cognitive functions in young and older adults.However, effects across studies are mixed. We conducted a meta-analysis to examine the hypothesis that training healthy older adults with video games enhances their cognitive functioning. The studies included in the meta-analysis were video game training interventions with pre- and posttraining measures. Twenty experimental studies published between 1986 and 2013, involving 474 trained and 439 healthy older controls, met the inclusion criteria. The results indicate that video game training produces positive effects on several cognitive functions, including reaction time (RT), attention, memory, and global cognition. The heterogeneity test did not show a significant heterogeneity (I2 20.69%) but this did not preclude a further examination of moderator variables. The magnitude of this effect was moderated by methodological and personal factors, including the age of the trainees and the duration of the intervention. The findings suggest that cognitive and neural plasticity is maintained to a certain extent in old age. Training older adults with video games enhances several aspects of cognition and might be a valuable intervention for cognitive enhancement.
