Walking: Spiced Up

Have you noticed your physician paying greater attention to your exercise habits? Healthcare leaders are calling on physicians and their industry to routinely prescribe exercise, in general--and walking, in particular. For example, the Journal of the American Medical Association (Berra, Ripee & Manson 2015) recommends that clinicians do the following to integrate physical activity counseling into their practices:
  • Make physical activity a vital sign at each clinic visit
  • Ask if the patient exercises regularly or engages in physical activity
  • Associate physical activity with reduced risk of heart disease, stroke, diabetes, and many cancers
  • Write a prescription for an agreed-upon daily physical activity
  • Encourage use of a pedometer and advise recordkeeping
I'm excited about the continued recognition of exercise as a vital part of health. Increasing your exercise frequency can be as simple as walking more. Here are some ideas for how to adapt high-intensity interval training (HIIT) to walking. Which will be your favorite?

High-Intensity Aerobic Interval Walking: Complete up to 10 high-intensity walking intervals lasting 4 minutes each, interspersed with 2-minute relief intervals (walking at a lower intensity). About 1 hour duration

Sprint Interval Walking: Complete 4-6 sprint-walking intervals lasting 30seconds each, interspersed with 4.5 minutes of light walking at a self-selected pace. 20-30 minutes duration

Step-Wise Interval Walking: Start with a relatively easy walking workload for the first 5 minutes, then increase intensity by 15% for 4 minutes and continue to increase intensity every 4 minutes. This program can be halted at a particular intensity or after a specific duration; follow with a cool down walk. 20-60 minute duration

Near-Maximal Interval Walking:
Perform a 5-minute walk at near-maximal intensity, followed by a 5-minute recovery walk; repeat. 20-60 minute duration

Supramaximal Interval Walking: Complete 7-10 sprint-walking intervals lasting 90 seconds, interspersed with 30 seconds of walking at a self-selected slower pace. 20-30 minute duration

Happy Walking!
