Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

14.9K
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...

Bones of the Lower Limb: Femur and Patella

9.3K
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...

Muscles that Move the Leg01:23

Muscles that Move the Leg

6.4K
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...

Area of Science:

  • Sports Science
  • Biomechanics
  • Exercise Physiology

Background:

  • Muscular asymmetries and imbalances in lower limbs are common in team sports.
  • These imbalances can affect performance and increase injury risk in athletes.
  • Core stability is fundamental for efficient force transfer and overall body control.

Purpose of the Study:

  • To evaluate the impact of a core stability training program on lower limb muscular asymmetries and imbalances in young team sport players.
  • To compare the effects of core stability training versus a standard warm-up on strength and jump performance.

Main Methods:

  • Twenty young footballers were divided into a core stability group (n=10) and a control group (n=10).
  • The core stability group performed a specific core training program daily, while the control group performed a standard warm-up.
  • Isokinetic tests and single-leg countermovement jumps were used to assess lower limb strength, imbalances, and asymmetries before and after the intervention.

Main Results:

  • The core stability group showed significant improvements in knee extensors and flexors peak torque, and flexors/extensors ratios.
  • Significant reductions in lower limb strength asymmetries were observed in the core stability group post-training (-71.4%).
  • The control group exhibited an increase in strength asymmetries (33.3%), contrasting with the core stability group's results.

Conclusions:

  • Core stability training is effective in improving lower limb strength and reducing muscular asymmetries in young soccer players.
  • Integrating core exercises into training regimens can optimize lower limb strength balance and potentially mitigate injury risks.
  • This study provides practical evidence supporting core stability training for enhancing athletic performance in team sports.
