Question

consider this claim: standing while you work at a computer is better for your health than sitting. which is the strongest evidence to support the claim? a study published in a journal devoted to physical activity found that subjects burned only 80 calories per hour while sitting, whereas they burned 210 calories per hour while walking. sales of standing desks have risen dramatically in recent years, which health journalist julia harmon says is part of a larger trend of americans becoming more health - conscious. in one study, office workers who switched from traditional sitting arrangements to standing desks reported better moods, more energy, and less fatigue. ted wilkerson, a health and fitness blogger, says that since switching to a standing desk, he has experienced greater mental alertness and physical energy.

Explanation:

The first option compares calorie - burn rates between sitting and walking, but standing is not walking. Sales of standing desks in the second option only show a trend, not direct health benefits. The fourth option is just an individual's anecdote. The third option is a study on office workers who switched to standing desks and reported better mood, more energy, and less fatigue, which directly supports the claim that standing while working at a computer is better for health.

Answer:

In one study, office workers who switched from traditional sitting arrangements to standing desks reported better moods, more energy, and less fatigue.
