Human Subject Research Opportunities

Human participants are critical to the success of our research studies. Human Physiology studies cover a wide variety of research of the human body.

Come help us!

Acute Hot Tub Study

We are currently recruiting young, healthy individuals for a study investigating the acute effects of hot tubbing. Study involves one screening session (60 min) and one experimental session (up to 3 hours), which includes 60 min in a hot tub. Must be fasted from food and caffeine on study day and must refrain from all medications and exercise for 24 hours.

Upon participation, subjects will be compensated up to $40.

ELIGIBLE?  Ages 18-40; no smoking, heart disease, or other chronic diseases; not currently taking prescription medications (except birth control); women must not be pregnant or currently breast-feeding; men must not be undergoing treatment to increase sperm counts.

If you are interested in participating, please contact Emily Larson via Email: or phone: 541‐346‐1033

Cycling Time Trial Performance

Research Volunteer Subjects Needed

Healthy, non-smoking males and females, age 18-40, are needed for studies on cycling time trial performance.

Subjects should be “active”, engaging in more than 5 hours of exercise a week, and accustomed to cycling for more than 3 hours at a time. The study lasts approximately 20 hours and will require 7 visits into the laboratory.

Subjects must not be on any medications (oral contraceptives acceptable), must not be taking herbal remedies or dietary supplements, and cannot be pregnant or currently breast-feeding.

Subjects may not be using illegal/recreational drugs. Subjects must not have had prior allergic reactions to drugs or medication, specifically antihistamines (e.g. fexofenadine/Allegra, ranitidine/Zantac) and not be currently taking non-steroidal antiinflammatory medications (NSAIDs). Participants will not be allowed to participate in vigorous exercise between the study visits. This study is being conducted in the Department of Human Physiology at the University of Oregon. Subjects will be compensated for their participation in this study. If interested please contact Matt Ely via Email: or phone: 541-600-4095

Hip Neuromuscular Control During Running

The Motion Analysis Laboratory is currently investigating the effect of hip muscle fatigue on hip muscle activity and mechanics during running.  In order to qualify for this study, you must be currently healthy without any major injuries over the past 6 months, between 18-45 years old, and running at least 20 miles per week, on average.  The study will take place over 2-3 sessions:
Session 1 = Strength and flexibility testing (1.5 hours)
Session 2 = Running before and after hip muscle fatigue (2.5 hours)
Session 3 = Strength testing before and after a fatiguing run (1 hour – optional)

Subjects will be compensated $10/hour for completing this study, with a maximum of $50 for completing all 3 visits

Hot Tub Study for Women

The DEPARTMENT OF HUMAN PHYSIOLOGY at the UNIVERSITY OF OREGON is currently recruiting women with a Body Mass Index (BMI) between 30-45 for a study investigating the effects of long-term heat exposure on cardiovascular and metabolic health.

The study involves sitting in a hot tub 3-4 times per week for 8-10 weeks (one hour per session), with testing at the beginning, middle, and end of the 8 weeks to look at possible changes in cardiovascular and metabolic health.


  • Female
  • Between age 18-40
  • Body mass index (BMI) between 30-45 kg/m2
  • No smoking, heart disease, or diabetes (slightly high blood pressure and pre-diabetes are okay)
  • Not pregnant or currently breast feeding



  • Screening session (<1 hour)
  • 30 heating sessions over 8-10 weeks (1-1.5 hours each)
  • 8 experimental sessions: 3 prior to and 3 following the 8-10 weeks of heating, 2 after 4-5 weeks of heating (2-4 hours each).


If interested please contact Brett Ely, M.S. at

Upon participation in this study, subjects will be compensated for their time up to $400.

Measuring Gait Stability with Accelerometers

The Motion Lab is developing a tool based on small wearable accelerometers for clinical use in detecting gait stability impairments in people who sustained a concussion. The purpose of this study is to establish the validity of the measurements and the reliability of the equipment in different environments, on different testing days, and by different examiners.

To be eligible you must be between the ages of 18-40 and healthy. You cannot have any diagnosed mental conditions affecting cognition such as concussion, memory loss, and ADHD. Also you cannot have any lower body injuries that are currently affecting your normal walking pattern.

The study consists of 2, 1 hour sessions that will be separated by 7-10 days. You will be asked to perform a simple walking task while responding to a concurrent auditory cognitive test.

Volunteers will be compensated $10/session for a total compensation of $20 if you complete the two study sessions.

Multi-joint study

Healthy participants needed for a multi-joint study

We are conducting research investigating the effects of sex on strength and sensory acuity across multiple joints.  If you are healthy, right-hand dominant, between the ages of 18 and 35, and have never had any problems with your neck, shoulder or elbow, you may be eligible to participate.  Information regarding your biological sex and use of gonadal (sex) hormones may be used to determine your eligibility.

The protocol consists of one 1 – 2 hour session. You will perform non-invasive sensory and motor tasks across multiple upper and lower extremity joints. You will be compensated $15 for your time and participation in this study.  Compensation will be given after the test procedure is finished.

Single Leg Squat Study

Integrated versus Isolated Intervention of Gluteal Musculature and its Effect on Medial Knee Displacement During a Single Leg Squat

This is a study about evaluating possible changes functional motion related to different types of exercise. The data collected will possibly help to determine exercises that can be utilized as an injury prevention method.
To be eligible you must be 18-35 years of age and recreationally active exercising at least 3 times a week and for at least 30 mins each time.
You are not eligible if you have a previous history of surgery to the lower and upper extremity, have had a significant injury to the lower or upper extremity in the last 6 months, and/or are currently experiencing any pain in any of the joints in the lower or upper extremity
If you have any questions and/or are interested in participating in the study, please contact me via email (Primary investigator: Leyla Kuz-Dworzak, ATC)

Study of Shoulder Muscles and Proprioception

Healthy participants needed for a study of shoulder muscles and proprioception

 We are conducting research related to muscles and proprioception at shoulder. Proprioception is the awareness of where a limb is in space without vision. If you are healthy and have never had any problems with your shoulder and neck, you may be eligible to participate. Testing requires the injection of anesthetic into the shoulder, maximum muscle contraction and testing without visual feedback. It is estimated that the entire testing process will take
approximately 3 hours. You will receive up to $75 for participating.
