Each participant wore an accelerometer to record their daily amount of physical activity, and the scientists calculated each person’s risk of having heart events like heart attacks or stroke based on established risk factors like age, cholesterol New York: Every minute of physical activity contributes to reducing risk of heart attack For the study, the researchers measured movement with accelerometers in 1,170 people aged 74-84 at eight centers across the US who had physical limitations but As such, the team set out to determine whether lower levels of activity may still have heart benefits for this population. Using accelerometers, the researchers measured the physical activity levels of 1,170 people aged 74-84 who were a part of the The agency compared self-reported physical activity during leisure time and objectively measured movements with a device called an accelerometer that is worn on the waist. At the individual level, there was a discrepancy between how much some people who is conducting physical-activity research with accelerometers. Accelerometers and exercise Researchers have been using accelerometers to study physical activity as far back as the 1980s, but the amount of information they collected was limited. Accelerometer readings of fewer than 100 counts a minute were considered sedentary periods. Anything more was deemed physical activity: Readings of 100-499 suggested exercise like slow walking or light housekeeping, and 500 indicated moderate walking or .

Physical activity as reported by the patients was collected the PASE questionnaire at baseline and two follow-up visits. At the third visit, accelerometer-based metabolic equivalents (METs), minutes of moderate activity, vigorous activity, and sedentary (dailyRx News Participants wore an accelerometer on their hip for seven consecutive days to measure the number of minutes they spent each day doing different levels of physical activity. Participants who used wheelchairs or were unable to walk were Accelerometer readings of fewer than 100 counts a minute were considered sedentary periods. Anything more was deemed physical activity: readings of 100-499 suggested exercise like slow walking or light housekeeping, and 500 indicated moderate walking or Physical education may be disappearing the researchers noted that none of the studies measured the children's activity objectively, and suggested that future research might make use of accelerometers to get a clearer idea of how much exercise kids .
