At the UK PintofScience.co.uk in Bournemouth on 15th May 2018, Dr. Susan Dewhurst (Senior Lecturer at Bournemouth University) presented the association between Leasure Time Physical Activity (LTPA) and mortality.


After the talk Susan shared a reference with me:


Arem H, Moore SC, Patel A, et al. Leisure Time Physical Activity and Mortality: A Detailed Pooled Analysis of the Dose-Response Relationship. JAMA Intern Med. 2015;175(6):959–967. doi:10.1001/jamainternmed.2015.0533.

It seems any level of exercise is better than none! (see figure above). Metabolic Equivalent (MET) 7.5 equates to 75 minutes per week of vigorous exercise or 150 minutes per week of moderate exercise, the mortality rate is 20% (0.8) lower than those who take no exercise. Doubling this exercise (15 MET) reduces mortality rate by 31% (0.69) compared to those who don't exercise.

7500 steps a day

"Walking 10,000 steps a day is not an official recommendation from the Centers for Disease Control and Prevention. Instead, the agency recommends adults engage in 150 minutes of moderate activity a week, such as brisk walking. To meet the CDC's recommendation, you need to walk about 7,000 to 8,000 steps a day, Tudor-Locke said." Source: LiveScience.
It seems that to achieve 15 MET you need to walk 14,000 to 16,000 steps a day (150 minutes per week of vigorous exercise or 300 minutes per week of moderate exercise).
