Summary
Females with weak hip abductors show increased knee abduction during running. This finding highlights the impact of hip abductor strength on running biomechanics and potential injury risk.
Area of Science:
- Biomechanics
- Kinesiology
- Sports Medicine
Background:
- Hip abductor weakness is a common issue.
- It may affect lower extremity movement patterns during dynamic activities like running.
Purpose of the Study:
- To investigate the relationship between hip abductor strength and knee abduction during the stance phase of running.
- To compare knee abduction in females with and without hip abductor weakness.
Main Methods:
- Observational prospective study conducted in a university biomechanics laboratory.
- 15 females with weak hip abductors and 15 with strong hip abductors participated.
- Lower extremity kinematics were analyzed using repeated measures ANOVA.
Main Results:
- Females with weak hip abductors exhibited significantly greater knee abduction during the stance phase of treadmill running.
- No other significant differences were observed in hip, knee, or pelvis kinematics in the sagittal or frontal planes.
Conclusions:
- Hip abductor weakness is associated with increased knee abduction during running.
- This biomechanical alteration may have implications for running-related injuries.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:20Muscles that Move the Thigh
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
