Evaluation of Physical Fitness and Hemodynamics Across a Diverse Population

Validation of an Interval Test for Monitoring Cardiovascular Function for Individuals With Different Levels of Physical Fitness

Source: ClinicalTrials.gov · Last updated 12 May 2026

Brief summary (registry, in English)

In this study, investigators will use the IFT 30-15 test, a six-minute walking test, and a treadmill test to assess the participants' cardiorespiratory fitness. For the treadmill cardiopulmonary exercise test (CPET), we will measure indirect gas exchange using a CPET device (K5). Maximum heart rate (HRmax) will be measured with a Polar heart rate monitor (model H10). The six-minute walking test will follow standardized procedures, and the treadmill test will follow a protocol of gradually increasing speed each minute. The study will involve two groups of participants: healthy individuals and pre-hypertensive individuals. While the IFT 30-15 test has been validated on a diverse range of athletes and physically active individuals, it has not yet been validated in individuals with similar characteristics to our participants (BMI \> 30 and limited cardiovascular function). Additionally, a variety of hemodynamic measures and other physical function measures such as sit-to-stand and push-ups will be assessed for all participants.
