Lisa, do you know how much physical activity you participate in over a week?
If you've been here on my email list for a while, you probably have an idea…
But wait, what does the rest of your day look like beyond your structured workout?
Are you actually NOT that physically active over the duration of the day?
Measuring incidental physical activity or how active your daily life is can be a surprising snapshot of truly how physically active you are. Current research supports not only structured workouts but also just moving more throughout the day. This is essential now more than ever!
If all you do is 30 minutes on the treadmill and sit the rest of the day, you are actually not as physically active as you can be. Your body benefits from continuous daily movement for even 5-10 minutes at a time and it can be as simple as getting up to walk.
But how do you know how physically active your day really is?
Daily physical activity can be monitored in various ways. The most simplistic way is to log your daily activities and determine the duration of time that is active and passive (e.g., walking to the bus stop versus sitting at your desk). In truth, though, who has time to really put the pen to paper.
More realistically, a pedometer might be just the answer to this laborious task!
Pedometers, first invented by Leonardo Di Vinci in the 16th century to accurately measure the number of steps taken by human or horse, are small devices that measure your daily steps. Pedometers are motion sensors that detect vertical movements such as acceleration and deceleration of the body.
Pedometer technology has advanced significantly over the past 10 years and the flimsy ones of the past are no longer the only option. Many pedometers are still mechanical that use a lever arm with a pendulum (e.g., YAMAX digiwalker) . This pendulum is displaced with each vertical acceleration of the body. The output is a quantitative value, which is equal to the number of movements of the pendulum and thus, the number of steps taken.
Newer technology, such as electronic pedometers (e.g., Omron) use accelerometer technology where electrical sensors interact with one another when a step is detected. Dual-axis sensors only react when a movement is accelerated to a certain level. For example, shaking a mechanical pedometer often registers a step as opposed to an electronic pedometer would recognize the shaking is not a true step. Many smart wearable technologies and apps found on your phone are accelerometers, which arguably are more accurate than a basic pedometer.
So what do I do with all these daily step values?
Consider tracking your steps for a week and calculating a daily average. If you are between 3,000-5,000 steps per day, you are close to the Canadian average. Research suggests that more than 10,000 steps per day will provide health benefits over the long term. But even increasing daily step counts by as little as 2,000 steps is showing positive health changes.

Physically active individuals are those who move over the course of the day. Pedometers and accelerometers are useful tools to help monitor how physically active you are day to day. Consider downloading an app for your phone, purchasing a reliable pedometer or even splurge and buy yourself a fancier wearable fitness tracker accelerometer!
Stay well and happy stepping,
