Walking is one of the best forms of exercise, but research suggests that how we walk may matter as much as how much we walk, particularly for adults aged sixty and over.
A randomized controlled study published in Mayo Clinic Proceedings investigated whether high-intensity interval walking could deliver greater health benefits than traditional moderate-paced walking. The study followed 246 men and women, with an average age of sixty-three, over a five-month study period.
Participants were split into three groups: a control group, a moderate-intensity continuous walking group, and a high-intensity interval walking group. Those in the interval group alternated short bursts of fast walking with slower recovery walks, performing at least five cycles per session on four or more days per week.
After five months, the interval-walking group experienced measurable gains in both leg strength and aerobic capacity. Isometric knee extension increased by thirteen percent, and flexion by seventeen percent.

This group experienced a significant drop in systolic blood pressure, a key marker for cardiovascular health. The moderate-paced walkers also improved—but not nearly to the same degree.
The study’s findings suggest that adding intervals to a walking routine may offer a low-risk, high-reward alternative to traditional strolls for aging adults looking to boost strength, energy, and improve cardiovascular health.
To incorporate interval walking into your routine, start by walking slowly for three minutes, then pick up the pace for three minutes—fast enough to hold a conversation without needing breath breaks.
Repeat this cycle five times per session. For best results, aim to complete this regimen at least four times per week. When using a treadmill, you can achieve the same effect by adjusting the speed and incline to match the intensity shifts.

This approach can be particularly beneficial for older adults, as it allows them to improve their physical fitness and reduce their blood pressure in a low-impact way. As people age, their ability to perform daily tasks and maintain their independence can be impacted by declining physical fitness.
By incorporating high-intensity interval walking into their routine, older adults can take a proactive step towards maintaining their strength, energy, and overall health. The study’s results are based on a randomized controlled trial, which provides strong evidence for the effectiveness of high-intensity interval walking.
The high-intensity interval training approach has been shown to be effective in improving physical fitness and reducing blood pressure in other studies as well.
