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? in one study, office workers who switched from traditional sitting arrangements to standing desks reported better moods, more energy, and less fatigue. 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. steve hutchinson, 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 is a study on office workers which directly relates to the claim about working at a computer (office workers using desks). The second option compares sitting and walking (not standing at a computer). The third option is a single - person anecdote (a blogger) which is less reliable than a study on a group (office workers).

Answer:

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