What’s the big deal about 10,000 Steps?
* Pedometer came to market in 1965 in Japan under the name “Manpo Kei” literally translated to “10,000 steps meter”
* 10,000 steps per day is not evidence based.
How Many Steps per Day is Optimal?
* Burton et. al, 2021 – Randomized crossover study. There are evidence low activity levels can blunt metabolic benefits from exercise aka Exercise resistance. Main objective of the study to investigate how many steps required to overcome exercise resistance.
Low group – average 2675 steps per day, Limited – 4759, Normal – 8481.
5000 isn’t enough – 8,000 steps enough. Between 5-8K is a good target to aim for health.
* Saint-Maurice et. al, 2020 – Observational Study. A greater number of daily steps was significantly associated with lower all-cause mortality. There was no significant association between step intensity and mortality after adjusting for total steps per day. Mortality risk consistently dropped till 12,000 Steps per day. There’s no significant difference between 12,000 & 16,000.
* Wang et al., 2008 - Maintaining high levels of daily physical activity during weight loss may be important to mitigate weight regain after weight loss.
Practical Application;
* 10,000 Steps per day is not a rule everyone must stick to.
* 5000-8000 Steps may be enough to overcome exercise resistance and get maximum metabolic benefits from exercise. Aim for higher end.
* Overweight & Obese individuals can benefit from higher step targets to lose excess weight quicker.
* Maintaining higher activity levels help prevent weight regain and maintain results long term.
