Study suggests moderately active people can have a positive influence on their friends

Encouraging the general population to increase their physical activity levels has long been a frustrating challenge for public health officials, but new research has unveiled a potential new way to reach sedentary individuals: through their physically active friends. According to a study published in the journal Plos One,  when sedentary individuals interacted with moderately active friends, they became more active themselves.

The study

Researchers at Keene University in New Jersey used previous research analyzing how social interactions with peers can influence individual physical activity levels to develop a mathematical model to simulate how social interactions can shape a community’s physical activity levels over time. Their model showed that their physical activity levels dropped when people stopped socializing. We saw this play out in real-time during the COVID-19 pandemic when most of us were cut off from our peer groups.

Their model also showed that when sedentary people interacted regularly with their moderately-active friends, they became more active over time. In other words, those of us who exercise regularly could have a positive impact on our less-active friends, encouraging them to move a little more. 

It’s important to note that this study focused specifically on moderately active people. That’s not to say that those of us who are training for marathons or ultras can’t also have a positive impact on our sedentary friends, but a sedentary person may view a marathon runner as having an unattainable level of discipline or enthusiasm for activity, which may not motivate them to get started.

How to encourage your sedentary friends to get active

Whether you’re training for a marathon or fitting a few 5Ks in between your busy schedule each week, you can help your sedentary friends warm up to the idea of a more active lifestyle. Here are a few tips to encourage them to get moving:

Plan active get-togethers

Meeting your friend for a coffee? Get those coffees to go and invite them on a stroll. Planning a beach day? Bring a beach ball, a frisbee, or some other game that’ll get everyone on their feet. Invite your friends on weekend hikes, suggest signing up for a recreational sports team, or plan to play some backyard games at your next barbecue. Anything that gets people out of their chairs is a win.

Try something new together

Your less-active friends may be intimidated to try going for a jog with you, so invite them to try an activity that you’re both novice at instead. Sign up for yoga classes, try a dance class, or sign up for golf lessons. If you’re both new at it, you’re both starting off on a somewhat even playing field.

Talk about your running, but not too much

Sharing your running achievements or training plans with your friends can be motivational, but be careful not to over-do it. Your friends don’t want to hear about the splits from your last workout, and talking about your recent chaffing mishap will likely turn them off of the sport. When you talk about running, talk about how it helps you so they can see the potential benefits. “I was had a stressful day at work yesterday, but I went for a run and felt much better,” or “I tried a new route the other day and discovered a really cute neighbourhood that I’d never seen before!” are great ways to lean into the mental or emotional benefits of running.
