单选题 A treadmill (跑步机) desk may be one thing. But what about a desk with a built-in exercise bike? A new study, in the July     26    of Applied Ergonomics, found people working at a cycling workstation burned calories at 2.5 times the rate as when they simply sat and typed. Pedaling didn't affect typing performance. Using a cycling workstation for 10 minutes every hour throughout a day could help desk workers lose weight and reduce the     27    of diabetes and cardiovascular (心血管的) disease, researchers said.     28    pedaling could improve cognitive function, they said.
    University of Utah researchers     29    10 normal-weight undergraduates and faculty members who reported spending 6.3 hours a day, on average, at a desk. Subjects, men ages 24 to 40, spent two 10-minute sessions     30    the Gettysburg Address. In one session, subjects pedaled and typed. In the other, they sat and typed.     31    were instructed to select a resistance level they could comfortably maintain for     32    periods without interfering with typing.
    Subjects burned 255 calories per hour pedaling and typing and 100 calories per hour sitting and typing. The exertion level was rated as very, very light. Transcription time     33    7.7 minutes while pedaling and 7.6 minutes while sitting. Subjects made an average of 3.3 and 3.8 errors in the pedaling and non-pedaling experiments,     34    Heart rate and oxygen     35    were substantially higher while pedaling and typing.
    The study was small and involved young fit men. A researcher is part owner in a company that is working with the university to develop a cycling workstation called an Active Desk.
