Walking briskly may lower risk of death in some adults: Study

Walking faster for 30 minutes per day can lower the risk of death in some adults, a new study suggests.

Researchers from Australia and Spain looked at 1 approximately 70, 000 adults between ages 40 and 69.

Participants were broken into four categories: under 5,000 steps a day, between 5,000 and 7,000 steps a day, between 7,500 and 10,000 steps a day and above 10,000 steps a day.

The researchers also timed each participant's peak 30-minute cadence, or the average steps per minute during the most active 30 minutes of the day.

Results showed that the group with under 5,000 steps a day, a level considered as a sedentary lifestyle, -- but with a peak 30-minute cadence of between 60 to 90 steps per minute -- had a lower risk of death than those with a slower peak 30-minute cadence.
