Step To It!

The Canadian Society of Exercise Physiology (CSEP) and the Public Health Agency of Canada recommend approximately 150 minutes per week of moderate physical activity (1,2).

Unfortunately, only approximately 49% of Canadians aged 18-79 get this amount (3), giving us an overall grade of C…which may have been a good enough grade to pass high school chemistry, but not enough to help prevent a variety of chronic diseases (such as high blood pressure, cardiovascular disease, cancer, dementia, depression, and osteoporosis) in the general population.

What can we do about it?

For better or for worse, devices have revolutionized the way we live, eat, shop, and work. Fitbits, pedometers, smart phones, and other off-the-shelf accelerometers have become more popular helping us to count our steps as well as track our energy expenditure and overall activity habits. You don’t need the most expensive step-counter on the market – a recent study has shown that using these devices (even the cheapest of pedometers) can help improve our physical activity levels on average (in both the short AND long-term) by ~400-1100 steps (4)!


But how many steps do I really need?

10,000 steps per day has been commonly spouted as the best goal for most adults to attain a healthy physical activity level (5) – and can be traced back to Japanese walking clubs in the 1970’s & 1980’s (6). However, this one-size-fits-all approach is not ideal for everyone…10,000 steps is likely too low for children who need to burn off energy (6). CSEP recommends a minimum of 60 minutes per day of moderate to vigorous activity for kids aged 5-17 (7). However, 10,000 steps is likely too high and unsustainable for the elderly or those with chronic diseases (6) and may increase risk of overuse injuries (8).


A recent meta-analysis (which summarizes and analyzes the results from several different studies – in this case 16 different studies) found that there was the most dramatic DECREASE in overall risk of death and cardiovascular disease when daily step count increased from sedentary levels (ie. less than 1,500 steps/day) to 5,000-7,000 steps/day (5,8). But improving daily step count beyond 7,000 steps towards the popularly coveted 10,000 step goal only slightly further decreased this risk of death and cardiovascular disease (5,8).


Long story short, for those who want to start a journey towards a more physically active lifestyle, gradually increasing overall activity level and working towards 5,000-7,000 steps per day not only benefits health and decreases overall risk of mortality. It’s likely more sustainable and less likely to cause overuse injuries.

FYI:

Be aware that these off-the-shelf accelerometers (within most smart watches and fitness monitors) are NOT perfect. These devices commonly over- or under-estimate your step count by around 9-13% (9,10) and become even LESS accurate (up to 20-30%) with slower gait patterns (10). This translates to a 900-1300 step difference in an approximate 10,000 step day. For example, if your device displays the coveted 10,000 steps, you may have actually done anywhere between 8,700 and 11,300 steps. While these devices can provide a good estimate of overall physical activity level, they are not 100% accurate.
