We are all coming off a year where – most likely – our workouts and total energy expenditure dropped off dramatically during the course of a typical day. It is totally understandable.
A whole new field of study has developed recently called inactivity physiology.
Inactivity Physiology Defined
The inactivity physiology paradigm can be defined as:
“Inactivity physiology represents a paradigm shift for how we think about how lifestyle causes disease. Simply put, the inactivity physiology paradigm says that “too little exercise” is not the same as “too much sitting” (physical inactivity) and that too much sitting has very potent effects on the body contributing to the most common diseases.”
Think about this for a minute. You get up early to go for an hour run or head to the gym for a long workout. You then hop in the car and drive 30-45 minutes to work. Once you arrive at the office, what happens? That’s right, you sit in front of your computer to work and for meetings. You then typically sit more through lunch and throughout the rest of the day. After work you repeat the 30-45 minute drive home, which is now most likely longer due to rush hour traffic. After you get home you relax a bit, sit and catch the news, sit more during dinner and then watch more TV following dinner.
Well if that is the case, then (most) of the benefits derived from your workout earlier in the day may be erased. Now I know you stressed your body during that hour run or strength workout at the gym. You may think loading your bones and muscles and alleviating some stress is enough. This is all good. Sure, but the issue remains, you’re sitting for eight hours or more each day.
Let’s be honest, we can all increase our activity level a bit more …don’t you think? You need to increase the activity you do throughout the day – above and beyond your exercise session…it’s critical. There is abundance of research showing that additional energy expenditure during the day is vital for long-term health. According to Knudsen and colleagues, “aerobic capacity fell 7 percent in 14 days after reducing steps from 10,000 to 1,500 a day in active men not in exercise programs“. Here are some examples to help avoid this and help add more activity into your day.
10 Ways to Help Prevent Inactivity Physiology
To offset this try adding a few of the following throughout your day to increase daily activity especially while at work:
- Build a standing work station at the office.
- Kneel periodically at your desk (when checking emails) and stretch those tight hip flexors.
- Get up every 20 minutes if you have a desk job and move and/or stretch.
- If your errands are <1 mile from your house – choose walking/biking rather than driving.
- Have “walking conference call” meetings at the office rather than sitting at a conference table.
- Whenever you take calls on a cell phone make sure you get up and walk and talk.
- Wear a pedometer and add 500 steps a day (goal: 10k/day) see Knudsen research paper below.
- Turn your lunch into your workout time. Or take a long walk.
- Limit your TV watching to <10 hours a week.
- Your goal this week: try to stand one hour each day over the course of the week.
