Research with KRSS

research study with KRSSThere are many active research projects underway in the Kinesiology, Recreation, and Sport Studies’ Exercise Physiology Laboratory. We are currently performing studies that involve assessing playground and garden physical activity levels in young children, cognition in children, enjoyment and exercise, validation studies, and several other topic areas.

If you would like more information about our studies or are interested in being a potential subject please contact the center at 865-974-6040 or

Would you like to be involved in a research study?

In order to determine your potential eligibility to participate, please take a few minutes to think about the following questions:

Are you between the ages of 18 and 65 years old?
If your answer is “YES,” you are eligible to participate in this research study.

Are you currently participating in a club, sport, or organization that requires you to attend structured exercise training or practices? Examples include varsity/club/intramural sports, ROTC, a physical education class (yoga, jogging, etc.)
If your answer is “NO,” you are eligible to participate in this research study.

Do you own a smartphone that: 1) is capable of receiving text messages, 2) allows internet access, and 3) is capable of taking and emailing photos?
If your answer is “YES,” you are eligible to participate in this research study

If the above criteria are met and you are enrolled, are you willing to comply with the following study requirements for the full two weeks of the study?

  1. Complete all three study visits across two weeks (HPER Building);
  2. Wear an accelerometer (small device worn on the hip to track physical activity) every day for at least 10 waking hours and keep track of when you take it off to sleep/bathe;
  3. Respond to four text message surveys (about three minutes per survey) every day and complete each survey within 60 minutes of receiving it; and
  4. After every bout of exercise on aerobic equipment (treadmills, cycles, stair- steppers, etc.), take a photo of the summary screen that shows duration, calorie expenditure and immediately email it to the research staff.

If you are unable to sufficiently comply with the above criteria, you may be removed after the first week of the study.

After reading through this information, if you think you are eligible to participate in the study, please respond with your continued interest.

Past Research

Here are some of the research projects that have been done in the last few years in the department.

  • Analyzed the effects of Actigraph Band Pass Filtering on Continuous and Intermittent Lifestyle Activities.
  • Determined how children’s ability to complete motor skills (jumping, running, etc.) is related to their physical activity and physical fitness levels.
  • Compared energy expenditure estimates of two physical activity monitors with measured energy expenditure during wheelchair locomotion.
  • Determined the accuracy of the Nike+® device for estimating speed, distance, and caloric expenditure on a treadmill.
  • Three fold purpose study: assessed the reliability of the ActiGraph GT3X+ ambient light sensor, identified a lux threshold to accurately discriminate between indoor and outdoor activities in children, and tested the accuracy of the lux threshold in a free-living environment.
  • Determined the step count accuracy of three pedometers and one accelerometer in pregnant women during treadmill walking.
  • Investigated the use of BOW-M for physical activity classification using hip worn accelerometer in youth.
  • Compared step/minute cut points for estimating light, moderate, and vigorous physical activity to indirect calorimetry during 18 structured physical activity and six hours of free-living measurements.
  • Assessed the influence of maturity status, percent body fat, physical activity, and gender on aerobic fitness in middle school youth.
  • Summarized the historical development of portable indirect calorimeters, reported on the validity and reliability, and described their principles of operation.
  • Compared physiological responses while wearing rocker bottom shoes to responses measured when wearing a standard shoe. They also gathered information to the comfort of the rocker bottom shoes.
  • Performed an eight-week pilot study to examine the effects of five-minute walking breaks for increasing steps per day and improving cardio-metabolic risk factors in sedentary office workers.
  • Examined the association between the homeostatic model assessment of insulin resistance and self-reported muscular strengthening activity in a nationally representative sample of euglycemic US adults.
  • Looked to develop an objective method that simultaneously tracks participant posture, desk position, and proximity to the desk.
  • Determined if the perception of weather is related to different characteristics of adults.
  • Determined the influence of television on health-related fitness in middle school youth.
  • Determined if television viewing increases enjoyment of exercise in college students.
  • A program was created by Knoxville Area Coalition on Childhood Obesity called “Kids Can BIKE!” in 2012. This program was created to increase physical activity, teach safe cycling skills, and explore Knoxville parks and greenways while having fun.
  • Used “natural” playgrounds, where natural elements are specifically designed into the landscape to promote imaginative, active play. Determined the differences in play area usage and sedentary and moderate-vigorous physical activity levels of young children on a traditional and natural playground.
  • Determined differences in physical activity intensity, type, and context, and behaviors in young children before and after renovation of traditional playground to natural playground.
  • Identified items related to exercise readiness and determined the dimensionality of exercise readiness using exploratory factor analysis.
