Summary
Foot core training improved joint coordination in recreational runners, reducing pronation and enhancing push-off efficiency. This intervention may help prevent running-related injuries.
Area of Science:
- Biomechanics
- Sports Medicine
- Exercise Physiology
Background:
- Running injuries are common in recreational runners.
- Foot joint coordination plays a crucial role in running mechanics.
- Targeted interventions may improve foot function and reduce injury risk.
Purpose of the Study:
- To investigate the effects of an 8-week foot core intervention on foot joint coordination in recreational runners.
- To analyze changes in inter-joint coordination patterns during running post-intervention.
- To determine if foot core training influences calcaneus and midfoot (CalMid) and midfoot and metatarsus (MidMet) joint coordination.
Main Methods:
- Secondary analysis of a randomized controlled trial with 87 recreational runners.
- Intervention group (IG) performed 8-week foot core training; control group (CG) performed placebo stretching.
- Foot segment motion captured during treadmill running (9.5-10.5 km/h) using vector coding technique.
Main Results:
- Foot core intervention altered frontal plane coordination of CalMid and MidMet joints at heel strike and early stance.
- IG showed decreased frequency of in-phase coordination (suggesting longer foot supination) and anti-phase coordination with distal dominancy.
- IG demonstrated increased frequency of anti-phase coordination in the transverse plane during propulsion, indicating reduced calcaneus abduction.
Conclusions:
- Foot core training positively affects foot joint coordination during running.
- The intervention enhances resistance to calcaneus pronation and creates a more rigid lever during push-off.
- Findings suggest foot core intervention can reduce running-related injuries.

01:28Muscles of the Leg that Move the Foot and Toes
1.5K
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....

01:10Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:24Muscle Coordination and Action
1.5K
Muscle coordination is a complex and finely tuned process essential for smooth and purposeful movements like flexion, extension, adduction, abduction, and rotation. The human body orchestrates the actions of various muscles working in concert, each with a specific role. Four functional types describe how muscles work together: agonist, antagonist, synergist, and fixator.
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement....

01:10Bones of the Lower Limb: Tibia and Fibula
3.3K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

01:07Development of the Limb Synovial Joints
1.4K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:11Direct Motor Pathways
2.0K
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...
