Wearable Step Counters Offer Exercise Leg Up?
Sometimes it’s hard to get moving. So setting a goal for the number of steps you walk each day can be a good?motivator. But how to keep track of your total? A new study finds that many of the?widely available wearable step counters?actually keep a pretty accurate count. The research is in?JAMA.?For the study, 14 volunteers agreed to?walk on treadmills?while decked out with 10 popular wearable or smartphone counting technologies. The devices were compared with actual?manual counts?of either 500 or 1500 steps. So how’d they do?

treadmill n.跑步機
deck out 裝飾，打扮
Smartphone apps were better step trackers than wearable tech—but the wearables were not terrible either. They?typically slightly?undercounted, compared to?manual tallies, for example. Some of the?discrepancybetween the apps and wearables could be because volunteers’ phones were in a pocket close to their hips where it may be easier to pick up specific movements. But in everyday life smartphones would not always be in a pocket, of course.

discrepancy n.差異脓匿，不符，迥異
Of the 10 apps or devices studied, the Fitbit One was most accurate and had good?consistency.?Although none of the counts were that far off—for example, clocking just 1200 steps instead of 1500—the findings suggest that it’s probably a good idea to take the numbers as a loose estimate. And if you can’t walk somewhere, you can still feel motivated to park a few hundred steps away from your final destination.
經(jīng)過測試的10個手機應用或設備中宦赠，F(xiàn)itbit One 的準確度最高陪毡，具有很好的穩(wěn)定性。盡管哪個設備的計數(shù)結果都沒那么離譜——比如走了1500步卻只算了1200步——研究結果告訴我們：對計數(shù)結果別太較真勾扭，看個大概就好了毡琉。如果沒法走著去某地，要是真想運動妙色，你依然可以提前下車走幾百步到達目的地桅滋。
consistency n.連貫性，一致性
