- Original description
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.Read full original descriptionShow less
Validation of an Interval Test for Monitoring Cardiovascular Function for Individuals With Different Levels of Physical Fitness
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.
Inclusion: Adults (18 + years of age) without restriction on sex, health status or physical fitness.
Exclusion: Lower extremity injury or surgery within the past 2 years (if not fully rehabilitated); Presence of acute injuries and/or illnesses that limit maximal exertion during physical fitness testing; Inability to walk without assistance.
