简要总结
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.
详细描述
Study description This study is a work package of the ACT-ON project, aimed at validating different physical fitness assessment tests in diverse populations considering their health status. Thus, in the proposed study we will assess the potential for validating a selected cardiovascular function test for individuals with varying levels of physical fitness. The chosen test, the Intermittent Fitness Test 30-15 (hereafter referred to as IFT 30-15), is a field test commonly used to measure or determine aerobic capacities. More specifically, IFT 30-15 allows for the assessment of maximum oxygen uptake (VO2max), maximum heart rate (HRmax), as well as anaerobic capacity and capacity for intermittent high-intensity running. Of particular importance to us is the test's high potential to determine VO2max and HRmax, which consequently allows for defining workloads in specific training zones.
To collect the necessary data, the investigators will use a range of instruments and tools in all planned studies in the following order:
Upon arrival at the laboratory of the Institute of Sport at the Faculty of Sport, the investigators will measure participants' basic anthropometric characteristics and body composition. the investigators will use a stadiometer and anthropometer (GPM, Model 101, Switzerland) to measure height, and body mass will be measured using a multi-frequency bioelectrical impedance device (InBody 720: Biospace, Korea). Blood pressure will then be measured using the Omron M6 device.
