Principal Investigator: Dr. Jordan Guenette

We are recruiting MALE and FEMALE healthy recreational and competitive road cyclists and triathletes for a study investigating how different bicycle riding positions effect the mechanics of breathing.


  • Male or female
  • 19-49 years of age (inclusive)
  • Normal lung function as per % predicted values for age and sex
  • Body mass index greater than 18 or less than 30 kg/m2
  • Able to read and understand English
  • Regularly trains and/or competes at a regional, national or international level as a road cyclist or triathlete


Participation involves two visits:

  • Visit 1: Breathing tests followed by an exercise test (VO2MAX test) on an upright stationary bicycle.
  • Visit 2: Breathing tests followed by a cycling test at a constant intensity in three common riding positions.

Time Commitment:

  • Each visit will take approximately 3 hours for a total of 6 hours over 2 visits.


Participants will receive an honorarium and a detailed fitness assessment.
