NCT ID: NCT06168565

Last Updated: 2023-12-20

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 23 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-08-25
• Study Completion Date: 2023-09-27

Brief Summary

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?

Study Groups

Sequence 1

Measures of end-diastolic peak velocity, systolic peak velocity, heart rate, and arterial diameter will be collected for two minutes, two minutes before, at the 8th minute after the start of the IPC administration, and two minutes after the conclusion of each IPC protocol. End-diastolic peak velocity and systolic peak velocity will be measured across different phases of the IPC cycle (all cuffs inflated, half of the cuffs inflated, and all cuffs deflated). Both the athletes and assessors will be unaware of which protocol is being carried out. All protocols will be performed with participants lying down in a supine position, on a stretcher. The moderate pressure protocol applies a pressure of 80mmHg and the high pressure protocol applies a pressure of 200mmHg.

Group Type: EXPERIMENTAL

Intermittent pneumatic compression (AirRelax)

Intervention Type: DEVICE

Moderate pressure (around 80mmHg); high pressure (around 200mmHg), both applied on the lower-limbs
