Thank you for participating in our survey about your physical activity. As you may recall, the goal of this study is to understand a person's daily experience and activity. The purpose of this survey is to recap your physical activity levels in the past week and ask you some questions about your views of your own physical activity.

The first section of the survey asks about your recent levels of physical activity. The next section ask about your views of your own physical activity. Sometimes you may not know the exact answer to a question; if this happens, just provide the best answer you can.

Again, we appreciate your participation.

Before we ask you about your physical activity, we would like to explain what we mean by physical activity and sedentary behavior. Please carefully read the definitions below.

Physical activity is defined as any movement you do with your muscles that requires your body to use energy. The term "physical activity" should not be mistaken for "exercise." Exercise is only one type of physical activity that you do; it is oftentimes planned, structured, repeated and is intended to improve your physical fitness or to keep you fit. We are asking about physical activity, which not only includes exercise, but also other activities that involve bodily movement and are done as part of playing, working, active transportation, house chores and recreational activities.

Sedentary behaviors are times when you are awake; when you are sitting, reclining, or lying down; and when your body uses very little energy. For adults, examples of sedentary behaviors include using electronic devices (e.g., television, computer, laptop, tablet, phone) while sitting, reclining or lying; reading, writing, or talking while sitting; sitting in a bus, car, or train.

During the last 7 days, how physically active were you?

When considering how physically active you were, please include all of your light, moderate, and vigorous activities over the last 7 days.

During the last 7 days, how sedentary were you?

During the last 7 days, on how many days have you done a total of 30 min or more of physical activity, which was enough to raise your breathing rate? This may include sport, exercise and brisk walking or cycling for recreation or to get to and from places, but should not include housework or physical activity that may be part of your job.

Now we will ask you about the amount of time you spent in different sedentary and physically active behaviors. When answering these questions, please consider the different activities that you perform at home, work, while travelling, or while doing leisure activities. We understand that recalling the amount of time you spent in each of these activity categories can be difficult, but please try to give your best estimate.

We would now like for you to tell us about your physical activities over the last week.

We are interested in finding out about the kinds of physical activities that people do as part of their everyday lives. The question will ask you about the times you spent being physically active in the last 7 days. Please answer each question even if you do not consider yourself to be an active person. Please think about the activities you do at work, as part of your house and yard work, to get from place to place, and in your spare time for recreation, exercise or sport.

Think about all the vigorous activities that you did in the last 7 days. Vigorous physical activities refer to activities that take hard physical effort and make you breathe much harder than normal. Think only about those physical activities that you did for at least 10 minutes at a time.

During the last 7 days, on how many days did you do vigorous physical activities like heavy lifting, digging, aerobics, or fast bicycling?

If you did not do any vigorous physical activities during the last 7 days, please enter "0."

Think about all the moderate activities that you did in the last 7 days. Moderate activities refer to activities that take moderate physical effort and make you breathe somewhat harder than normal. Think only about those physical activities that you did for at least 10 minutes at a time.

During the last 7 days, on how many days did you do moderate physical activities like carrying light loads, bicycling at a regular pace, or doubles tennis? Do not include walking.

If you did not do any moderate physical activities during the last 7 days, please enter "0."

Think about the time you spent walking in the last 7 days. This includes at work and at home, walking to travel from place to place, and any other walking that you have done solely for recreation, sport, exercise, or leisure.

During the last 7 days, on how many days did you walk for at least 10 minutes at a time?

If you did not do any walking during the last 7 days, please enter "0."

We will now ask you about your physical activity and sedentary behavior over each of the 7 days of the study.

When considering how physically active you were, please include all of your light, moderate, and vigorous activities over the last 7 days.

How would you describe your level of physical activity over the last 7 days compared to your typical level of physical activity?

How would you describe your level of sedentary behavior over the last 7 days compared to your typical level of sedentary behavior?

The next questions are about your participation in muscle-strengthening exercise.

The questions within this section relate to the physical activities that you perform during your leisure-time only. When we say leisure-time we mean your free-time and the activities that you perform that are NOT done as part of your work/job, transportation (moving to a different location), or as a part of household activities (chores). The types of muscle-strengthening exercise modes that we are interested in include;

• Use of weight machines (typically in a gym or fitness center)
• Bodyweight exercises (including push-ups, sit-ups)
• Resistance exercises (using resistance bands or free weights like dumbbells)
• Holistic exercises (including Yoga, Tai-chi and Pilates)

There are no right or wrong responses to the following questions, we are interested in your open and honest feedback.

During the last 7 days, did you do any muscle-strengthening exercise?

The type of muscle-strengthening exercises include: Use of weight machines to do e.g. leg press, chess press, lat pulldown (typically in a gym or fitness center), body weight exercises (including push-ups, sit-ups), resistance bands (using resistance bands or free weights like dumbbells), holistic exercises (including Yoga, Tai-Chi, and Pilates)
