简要总结
The aim of this randomized crossover trial is to assess the hemodynamic effects caused by the use of 2 distinct intermittent pneumatic compression protocols on athletes.
The main questions it aims to answer are:
- Does intermittent pneumatic compression enhance athletes blood flow?
- If yes, what pressure is better to cause this enhancement?

结局指标
主要结局
End-diastolic peak velocity
时间窗: 2 minutes before the IPC protocol, during (8th minute mark - at different phases of the IPC cycle), and 2 minutes after the conclusion of the 15 minute protocol.
End-diastolic peak velocity will be assessed in a supine position on the right common femoral artery using an ultrasound (Logiq e BT12; General Electric, Fairfield, CT, USA) with a 3 to 12 MHz multi-frequency linear phase array transducer.
Systolic peak velocity
时间窗: 2 minutes before the IPC protocol, during (8th minute mark - at different phases of the IPC cycle), and 2 minutes after the conclusion of the 15 minute protocol.
Systolic peak velocity will be assessed in a supine position on the right common femoral artery using an ultrasound (Logiq e BT12; General Electric, Fairfield, CT, USA) with a 3 to 12 MHz multi-frequency linear phase array transducer.
Arterial Diameter
时间窗: 2 minutes before the IPC protocol, during (8th minute mark), and 2 minutes after the conclusion of the 15 minute protocol.
Assessment of arterial diameter via automatic edge detection software (FMD Studio, Pisa, Italy) measuring the distance between the near and far wall of the intima
次要结局
- Heart rate(2 minutes before the IPC protocol, during (8th minute mark - at different phases of the IPC cycle), and 2 minutes after the conclusion of the 15 minute protocol.)
