Are Treadmills the New Prozac?

Uploaded: Jan 7, 2015
Ok, so everyone knows that regular exercise is a must if you want to attain and maintain good physical health – it lowers blood pressure, decreases the risk of heart disease and various cancers, the list goes on and on. But did you know that exercising in accordance with the public health recommendations is actually considered an effective treatment for people with mild to moderate depression (APA, 2014)? To be honest, I didn't realize that! I mean, I knew that the American Psychological Association (APA) recommends exercise for decreasing symptoms of depression, but I hadn't ever looked that closely at the research until preparing this post. And the research is compelling!

A meta-analysis from the 90s (North, McCullagh, and Tran, 1990) actually found that the more participants worked out, the lower their symptoms of depression. They also found that exercise was particularly effective at reducing depression in older adults. Blumenthal et al. (1999) later showed that individuals randomized to an aerobic exercise group were as likely to be partially or fully recovered from their depressive episode as those assigned to a group treated with antidepressants. Interestingly, people in the exercise group were significantly less likely to have relapsed (i.e., had another bout of depression) after 4 months, compared to folks in the antidepressant group. So in the long run, exercise was more effective than antidepressants at treating depression!

And the research looks pretty promising for anxiety as well. Researchers theorize that exercise provides the body with an opportunity to practice managing stress. The body reacts to stress, be it emotional or physical, in similar ways. Much like exposing the body to a small dose of a disease in the form of a vaccine so that it can produce antibodies, exercise is theorized to provide the body with an opportunity to practice managing and recovering from stress.

So what's ideal? The public health recommendation is for 5 days/week of moderate-intensity exercise (e.g. brisk walk) lasting at least 30 minutes, or 3 days/week of intense exercise (jogging) lasting at least 20 minutes. There is significant research to suggest that strength training is as effective as aerobic exercise, particularly for women (for more info, check out this book), though if your aim is to decrease anxiety, cardiovascular activity is considered superior to strength training (Steptoe et al., 1989). Strength training, stretching (such as yoga), and aerobic activity have been shown to be equally effective at reducing symptoms of depression.

So what's realistic? As a gym rat and yoga instructor, this is something I've thought a lot about. I used to be an avid runner who didn't consider anything less than 5 miles to be a workout. I then developed sciatica and had to give it up. When I was first recovering I could only walk on the treadmill. Since I wasn't running, I loaded up several seasons of Six Feet Under to watch while I "wasted my time" walking on the treadmill. Over time though, I found that I actually looked forward to walking. I could do it everyday, instead of needing time in between to recover, and, coupled with a day or two each week of strength training, I felt like I was in the best shape of my life. These days, I hit the elliptical several times a week and do one day of strength training.

If you don't have time to meet the public health recommendations, consider downloading the 7 Scientific Minute Workout app for your smartphone. The app is based on this awesome article in the NY Times. I have several clients who swear by this app and often end up repeating it throughout the day.

If you have absolutely 0 time, consider finding ways to work some exercise into your current routine. Could you take the stairs instead of the elevator? Ride your bike to work one day a week? Do calf raises while cooking dinner, or squats while watching the news? What's one change you could make?

I have worked out most of my life. Over the past 5 years, I have had over five major surgeries that did not allow me to workout regularly during each recovery. This was a Huge challenge physically, but even more so Mentally. I did not feel motivated, happy or as "alive" as I typically do.

Once I received the "green" light to workout again, I immediately felt like I got my life back! However, each time I remember walking into the gym again and feeling like I almost couldn't do it again. I felt so sluggish from Not working out and my drive was gone.

Then, I get on the bike and by 15 minutes in I feel my endorphins kick in, my energy level increase, stress decrease and my mental focus coming back again. By the time I was finished with a 45 minutes of cycling, it was if I was given a "secret potion" that renewed me head to toe.

I have been down mental and physical path after each surgery, and evert time I am amazed how much happier and healthier mentally and physically I feel when I can "move" my body and use it how it was created to do so.

Physical exercise truly is part of the circle of "Living."

Indeed, I've often found that expectations are the real barrier when it comes to things like exercise, meditation, and diet. We have all of these expectations for ourselves that result in guilt and shame when not met. So we avoid the guilt and shame by avoiding the activity, when in fact we should be addressing our expectations. And, again, if the aim is to be healthy and happy, there is nothing that says you need to run a marathon or suffer through interval training (though both provide excellent ways to get in shape:)). You just need to be consistent and diligent - that's what the research suggests.
