High Performance Centre (CAR) Study

High Performance Centre (CAR)

Scientific department of High Performance Centre (CAR) in Sant Cugat, has made a strict scientific study to prove the efficiency of Colibrí garments.

This study consist of 2 parts:
1. Dynamic study: assess whether the use of Colibrí affects to actions like jump or running.
2. Medical study: assess whether the use of Colibrí protects against muscle injuries.


1.1 Control of inefficient muscular movement during running.


The movements in the rectus femoris, vastus externus and vastus medialis of the quadriceps which occur at the moment when the leg impacts on the ground were measured.

The results corroborate that inefficient muscle movements are significantly greater in muscles not protected by Colibrí garment.

Less inefficient muscular movement implies a better energy efficiency.


1.2 Assessment of the limitation of the maximum passive articular movement of the hip at rest. Flexion and extension.


By videographic it is assessed the maximum amplitude of movement under 3 different circumstances:

a) Colibrí tights
b) Conventional tights
c) Without tights

The assessment was carried out on the muscles groups on the front and rear by means of the Ridge, Thomas and hip flexion tests (ischiotibials).


A slight reduction in the range of maximum movement was observed (1°).

In this active limitation of maximum movement, Colibrí acts as a protector against femoroacetabular impact, preventing the muscle reach its maximum extension where the risk of injury is higher.

1.3 Assessment to affectation to jump.


The mechanics of jumping vertically were assessed by 3 different circumstances:

a) Colibrí tights
b) Conventional tights
c) Without tights

With Colibrí tights, flexion of knees was slightly reduced during the phase of impelling the jump, but there was no interference neither the maximum force or the performance of the jump (height gained).

1.4 Assessment to affectation of efficiency and effectiveness while running.

Colibrí compression garments, do not interfere with neither the length or the frequency of stride, indicating that there is no effect on running efficiency and effectiveness.

2.1 Assessment of protective effect during eccentric exercise.

High intensity or high volume of eccentric exercise can cause muscle injuries at sarcomere level, which is the main cause of Delayed Onset Muscle Soreness (DOMS), also known as muscle fever.


This type of cause of injury is habitually used as an experimental model for muscle injuries in humans.

A procedure was used to cause DOMS by means of continuous running on a 12% negative slope for 40 minutes at sufficient intensity.

All the subjects underwent the procedure while wearing Colibrí HamsQuad on one leg.

A significant increase of indicators of injury (albumin, CD3, MPO) was recorded in samples from the unprotected leg in relation to those from the unprotected leg.


Muscle biopsies were carried out on the vastus externus in both legs of all subjects, 48 hours after the doms was caused, with the following result:

Microscopic image A, shows the muscular fibres perfectly in line and in their natural formation after having done physical execise with Colibrí compression and muscular control garment.

Microscopic image B, shows the muscular fibres with some alterations and micro fractures after having done the same physical exercise without Colibrí compression and muscular control garment.

This result proves the protector effect of Colibrí garments.
