What exactly is meant by brisk walking? What is the pace that should be sustained? Some say it is that which is faster then a leisurely stroll. Some say that it requires that we increase our metabolic rate to three times that of sitting still. Other say that it should increase our heart rate to 70% of its maximum. The Centers for Disease Control recommend a pace in which you can talk but not sing. How are we able to figure this out? A study published in The British Journal of Sports Medicine put together the results of 38 previous studies that concentrated on the number of steps per minute, heart rates, respiration intensity, different ages and varying body mass indexes to try to come up with a number of steps per minute that would constitute brisk walking. What they came up with was 2.7 miles per hour or simply 100 steps per minute. How do we make this as simple as possible to figure out? Just count the number of steps you take in 6 seconds and multiply it by 10. Following this pace for 30 minutes should be enough for most people to maintain a healthy blood flow throughout their body.
