If you can walk briskly you are in good health. You are likely to have good musculature, balance and endurance, indicators of good cardiovascular health.
A June 2019 study published in Mayo Clinic Proceedings claims walking pace, defined as slow, steady/average or brisk, was the strongest predictor of how long a person would live, with a slow pace being associated with shorter life expectancy.
A female slow-walker could expect to live to be between 72 and 85 years old, whereas a brisk-walking woman could live to 87 or 88. For men, the slow walkers’ life expectancy ranged from 65 to 81, while the fast walkers lived to be 85 to 87.
A walking speed of 4km/hr or less is considered slow and that of 6km/hr or above fast.
