Intensive unilateral core training improves trunk stability without preference for trunk left or right rotation.
Journal of Back and Musculoskeletal Rehabilitation
|December 4, 2014
Summary
Unilateral core training enhances trunk stability in both rotational directions. This study found no preference for left or right trunk rotation improvement after intensive unilateral stability training in athletes.
Area of Science:
- Sports Science
- Biomechanics
- Exercise Physiology
Background:
- Trunk stability is crucial for athletic performance and injury prevention.
- Co-activation strategies can improve multi-directional trunk stability.
- The effect of unilateral core training on directional preference in trunk rotation remains unclear.
Purpose of the Study:
- To investigate whether intensive unilateral core training leads to a directional preference in trunk rotational stability.
- To determine if trunk rotational stability improves equally in response to left and right perturbations after unilateral training.
Main Methods:
- An intervention study involving 16 female basketball players was conducted over eight weeks.
- Eight participants underwent unilateral core training targeting one side of the trunk, while a control group received no additional training.
- Rotational trunk stability was assessed by measuring angular displacement against sudden rotational perturbations using a motion analyzer.
Main Results:
- The trained group demonstrated a significant reduction in angular displacement for both left (−26%) and right (−24%) rotational perturbations (p < 0.05).
- No significant difference in improvement was observed between left and right rotational stability.
Conclusions:
- Intensive unilateral core training effectively improves multi-directional trunk stability.
- The training does not induce a directional preference for trunk rotation, suggesting a generalized improvement in stability.

Muscles of the Pelvic Floor and Perineum
6.6K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Muscles of the Abdomen
4.7K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

Assessment of the Abdomen II: Percussion
3.7K
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.

Muscles of the Vertebral Column
4.6K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

Eccentric Axial Loading in a Plane of Symmetry
737
Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

Abdominal Regions and Quadrants
20.0K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...
