Specially programmed PDAs, or personal digital assistants, can prod middle-aged and older Americans - the most sedentary segment of the U.S. population - into increasing their physical activity levels. One surprise was the participants' positive response to the program's persistence. The PDA users liked the three additional "reminder" beeps that went off if they failed to respond to the first one. In fact, almost half of them wound up responding to the PDA only after being beeped for the fourth time. Researchers note that developing approaches to help people increase their exercise frequency, while taking into account an individual's schedule and environment, is particularly important.
