Hemodynamic Effects of Intermittent Pneumatic Compression for Sports

University of Maia23 enrolled

Overview

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?

Outcomes

Primary Outcomes

Arterial Diameter

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

Time frame: 2 minutes before the IPC protocol, during (8th minute mark), and 2 minutes after the conclusion of the 15 minute protocol.

End-diastolic peak velocity

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.

Time frame: 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

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.

Time frame: 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.

Secondary Outcomes

Heart rate

Assess any changes in heart rate.

Time frame: 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.
