Over the past couple of years, we have collectively seen the various ways in which COVID-19 has disrupted our lifestyles. In the case of runners, a recent Faculty of Kinesiology study shows this disruption led many of them to change the way they train.

Using data from the Wearable Technology Research and Collaboration (We-TRAC) Citizen Science program, researchers followed runners’ training habits through GPS-embedded wearable technology to analyze the impact of restrictions early in the pandemic. Lead author of the study is Zoe Chan, who is currently studying for her PhD at ��ݮ����Ƶ����, with a joint doctorate at Hong Kong Ply Tech University.

With many countries around the world in lockdown and many gyms closed in 2020, the participants of this study ran more; however, they were not running for longer periods of time, nor were they increasing their intensity. They were, however, running more frequently per week and running outdoors more, the data shows.

According to the study, published in January 2022, “Runners ran three kilometres per week more, added 0.3 training sessions per week, ran an additional 0.4 sessions outdoors, but there was no significant change in the intensity or duration of training sessions. Our findings suggested that runners adopted slightly different training regimen as a result of COVID-19 restrictions.”

About the study

The We-TRAC program was launched by ��ݮ����Ƶ���� Running Injury Clinic director Dr. Reed Ferber, BPE’93, PhD, in 2018 and is funded through the Natural Sciences and Engineering Research Council of Canada. 

Data were collected nine months before and after the start of restrictions in March 2020 from 65 participants from five different countries and 11 different cities. The training records show frequency, intensity and duration of participants' training.

“This type of research has been conducted since the beginning of COVID-19, with the goal of gauging how best to support people in staying physically active during restrictions,” says Chan.

Chan notes that running more frequently, rather than for a longer duration, could actually be a benefit as “longer runs are associated with fatigue, and that could increase your injury risk.”

Chan says the We-TRAC technology has made it easier to conduct a study of this nature.

“Previous studies used a survey-based type of research method, which comes with a lot of recall error,” she says. “One unique aspect of our research is that we can narrow it down to how much everyone is running on a weekly basis, down to the kilometre or 0.1 kilometre.

Scientists rely a lot on data. Anything we say, we have to back it up with data. The good thing about wearable sensors is that it’s real. Live data is something we can’t (get) in the lab.

With a much larger database, Chan adds, “We would be able to answer a lot more research questions, not just refined to running.”
