The human body is a complex system of chains, or 'slings', that help us move better, produce more force, and create more speed. These chains are made up of muscles, fascia, and ligaments all working together to create stability and mobility. Anatomy slings, or myofascial slings, were first described by Vleeming and consist of muscles, fascia, and ligaments working together to create stability and mobility. These slings are integral to our ability to generate efficient dynamic movement. For example, the anterior oblique system (AOS) consists of the external oblique and internal oblique, connecting with contralateral adductor muscles via the adductor-abdominal fascia. When this group of muscles contracts together, it provides stability by acting like an abdominal binder, compressing the entire pelvic girdle, resulting in force closure of the symphysis pubis. The body has many sling systems, including the posterior oblique system, the deep longitudinal system, and the lateral system.

| What are muscle slings? | Also known as 'myofascial slings', muscle slings are groups of muscles, fascia and ligaments that work together to create stability and mobility. |
| What are myofascial slings made of? | Myofascial slings are made of muscles, fascia and ligaments. |
| How do they work? | When muscles contract, they produce a force that spreads beyond the origin and insertion of the active muscle. These forces are transmitted through structures within a myofascial sling, allowing forces to be produced at a distance from the origin of the initial contraction. |
| Where are they located? | Myofascial slings are located in the lumbo-pelvic region of the body. |
| What do they do? | Myofascial slings provide stability and mobility, helping the body move better, produce more force and create more speed. |
| What happens when they don't work properly? | When there is a weak link in the chain, it can create dysfunction and poor performance. This can lead to issues such as lumbo-pelvic pain and dysfunction, particularly in high-impact athletes and expectant or postpartum women. |
| How can they be strengthened? | Exercises such as planks or crunches can strengthen isolated sections of the anterior oblique sling. Dynamic training using myofascial slings is also beneficial. |

Anatomy slings are made up of muscles, fascia and ligaments working together to create stability and mobility
Anatomy slings, also known as myofascial slings, are made up of muscles, fascia, and ligaments working together to create stability and mobility. They are integral to our ability to generate efficient dynamic movement. The superficial muscle activity should occur in synergy with the deep muscles.
The body is a complex system made up of many of these anatomical slings. When the slings are working efficiently, they help us move better, produce more force, and create more speed. However, when there is a weak component in the sling, clinicians often address the muscles individually and a person's general movement pattern rather than the slings.
The two slings of the posterior oblique system (POS) form a large X across the back of the torso, from each shoulder to the opposite hip. The anterior oblique system (AOS) is the front-side mirror image of the POS. It consists of two lines of muscle and fascia, each running diagonally from the sides of the waist to the front of each inner thigh. The AOS and POS work antagonistically, with the muscles of one lengthening as the other contracts.
The posterior oblique sling consists of the latissimus dorsi muscle, the opposite side gluteus maximus muscle, and the interconnecting thoracolumbar fascia. This sling crosses at the level of the lumbosacral junction and provides force closure to the sacroiliac (SI) joint, allowing for coordinated movement during activities such as walking, climbing stairs, and sports-specific movements. The anterior oblique sling includes the external and internal obliques, the opposite side adductor muscle, and the connecting adductor abdominal fascia. It plays a crucial role in accelerating and decelerating the body during sport-specific movements, including changes of direction.
The coordinated movement between these two muscle slings is consistent with Gracovetsky's analysis of muscular patterns in shoulder counter-rotation during gait. The LD and contralateral GM muscles create a force couple that induces nutation on the GM side and counternutation on the LD side. This results in coordinated shoulder and pelvis rotations during gait.

Myofascial slings help with force closure and stability in the pelvic girdle
Myofascial slings are networks of muscles, fascia, and ligaments that work together to create stability and mobility. They are critical to stabilising the sacroiliac (SI) joint through force closure, which is essential for coordinated movement during activities like walking, climbing stairs, and sports.
The SI joints allow for some movement and, therefore, require control for effective force transfer between the trunk and lower limbs. Myofascial slings provide this dynamic stability by transmitting forces beyond the origin and insertion of the active muscle, allowing for force production at a distance from the initial contraction.
The three myofascial slings that provide force closure in the pelvic girdle are the posterior oblique sling, the anterior oblique sling, and the posterior longitudinal sling. The anterior oblique sling, for example, includes the external and internal obliques, the opposite side adductor muscle, and the connecting adductor abdominal fascia. When these muscles contract together, they compress the entire pelvic girdle, resulting in force closure and stability.
The lateral sling is another important myofascial sling for pelvic stability, especially during single-leg stance movements like walking. It includes the gluteus medius, gluteus minimus, and TFL, which work together to hold the pelvis level and prevent pelvic drop during dynamic movements.
By understanding and engaging these myofascial slings, individuals can improve pelvic stability, alleviate pain, and enhance overall movement efficiency.

Sling systems are important for athletes involved in high-impact activities
Sling systems, also known as myofascial slings, are a group of connective tissues called fascia that form a network of connective fibres. These fibres support and stabilise the body, acting as an internal body suit. The different fascial sling systems are responsible for connecting the muscular chains that make up our limbs and torso, providing support to our joints, bones, and organs.
There are four main fascial sling systems: the anterior oblique system, the posterior oblique system, the deep longitudinal system, and the lateral subsystem. Each system is responsible for specific movements and actions. For example, the anterior sling connects the pectoral muscles to the hip flexors, enabling movements like walking, running, and jumping. The posterior sling, on the other hand, connects the back muscles to the glutes and is commonly involved in gait patterns.
Understanding and training these sling systems is crucial for athletes, especially those involved in high-impact activities. By strengthening the muscles associated with each system and improving coordination between them, athletes can enhance their stability, strength, balance, and overall athletic performance. For instance, athletes in explosive sports such as football, soccer, basketball, or volleyball can benefit from training their anterior/posterior oblique sling system, which aids in rapid acceleration, deceleration, and explosive movements.
Additionally, specific exercises can be incorporated into training routines to target particular sling systems. For the anterior oblique system, exercises like cable or band rotational chops can enhance rotational power and stability. For the posterior oblique system, exercises such as reverse lunges with rows or cable or band pulls can improve an athlete's speed and agility. By focusing on these sling systems, athletes can improve their performance in high-impact activities and reduce the risk of injury.

The anterior oblique system (AOS) provides stability by acting like an abdominal binder
The anterior oblique system (AOS) is a subsystem that plays a crucial role in stabilising the anterior kinetic chain, which includes the joints of the pubic symphysis, hip, and lumbar spine. It is composed of the external oblique and internal oblique muscles, which connect with the contralateral adductor muscles via the adductor-abdominal fascia.
When these muscles contract together, they act like an abdominal binder, providing stability to the entire pelvic girdle. This results in a force closure of the symphysis pubis, which is essential for maintaining balance and posture. The AOS helps to transfer force between the lower and upper extremities, ensuring stability during dynamic movements.
The AOS is particularly important in sports that require rapid acceleration, deceleration, and changes in direction. For example, during a swing of a tennis racket, the AOS produces the movement and power, while the posterior oblique subsystem (POS) is crucial for decelerating the movement. The AOS is also stressed during pushing motions and plays a role in eccentric deceleration of an anterior pelvic tilt.
The AOS works in harmony with other anatomical slings, such as the posterior oblique sling, to provide optimal stability and mobility. These slings are comprised of muscles, fascia, and ligaments working together to create efficient movement. When the force vectors within these slings are balanced, they ensure optimal alignment of bones and joints. However, when there is a weak component in a sling, clinicians often address the individual muscles rather than the sling as a whole.

The posterior oblique system (POS) forms an X across the back, with muscles and fascia appearing continuous
The posterior oblique system (POS) is a musculoskeletal system that forms an X across the back, with muscles and fascia appearing continuous. The POS is also referred to as the posterior oblique sling, the back functional line, or the posterior oblique subsystem. It consists of the latissimus dorsi, the gluteus maximus, and the interconnecting thoracolumbar fascia. The gluteus medius, lower trapezius, and serratus posterior inferior may also be included.
The POS is one of two intersecting slings that run across the torso. The other is the anterior oblique system (AOS), which is the front-side mirror image of the POS. The AOS and POS work antagonistically, with the AOS contracting as the POS lengthens and vice versa. This relationship can be observed when throwing a ball: the right-handed thrower steps forward with their left foot, rotates their hips to the right, and then the right shoulder and arm follow with the throwing motion.
The POS plays a critical role in gait, particularly during the single support phase of gait, also known as the stance phase. Prior to heel strike, the ipsilateral hamstring muscle contracts to prepare the limb for weight-bearing. During this phase, the proximal hamstring also stabilises the ipsilateral pelvis against the activity of the quadriceps, preventing excessive anterior rotation of the ilium. Once heel strike occurs, hamstring activity decreases, and the role of limiting ilium movement is taken over by the gluteus maximus.
The POS provides force closure to the sacroiliac (SI) joint, allowing for coordinated movement and the transfer of energy between the upper extremities and the legs. This force closure provides stability to the SI region by distributing the load between the lower extremities, spine, and upper extremities. This stability enables activities such as walking, climbing stairs, and sport-specific movements like throwing a pitch.
The understanding and activation of the sling systems can revolutionise exercise routines. By implementing movements that activate a group of muscles along a particular sling, individuals can reinforce innately healthful and beneficial actions. This approach focuses on patterns of weakness rather than specific muscles and can lead to improved rotational strength, stability, coordination, grace, and athleticism.
