he

had what is called a “goose rump” --> talking about Secretariat in that article. So my conclusion is that a goose rumped horse can be fast LMAO

Secretariat  wasn't a speed horse, he was a galloper/distance horse...& wouldn't have been a great distance/galloping horse if he hadn't had the "large heart"...

Choosing a Riding Horse
Analysis of the Pelvic Region

By Deb. Bennett, Ph. D

Horse 3. Here we see extreme pelvic slope (32 degrees) or ‘goose rump”. However this mare shows an acceptable acetabulum placement (32 degrees of the pelvic length is composed of ischium), and overall pelvic length (33% of body length ). Her limitations mainly lie in leg retraction. She cannot swing the femur very far behind the vertical without crushing it against the ischium. The gluteus medius muscles on such horses are commonly hypertrophied (over developed ), since the arc of useful hind leg movement is more or less restricted to that part which the gluteals power. Her thrusting power is diminished for another reason. The point of greatest hind leg leverage occurs when the femur is at 90 degrees to the hip line. If, when the femur is so angled, the hock and hoof lie under the ischium, the structure is ideal for an equal mix of upward and forward thrust. In this mare however , the hock and hoof lie in front of the acetabulum when the femur makes its 90 degree angle. “Goose rump” is thus a structure that promotes upward thrust at the expense of forward thrust – “level hips” is just the opposite.
