Differences between abductors and adductors

machine abductors

The abductor and adductor muscles of the hip are commonly called "abductors" and "adductors," but their classification is based on the specific movements they perform. The abductors are responsible for abduction movements, while the adductors allow adduction movements. These movements involve the lateral displacement of body parts toward or away from the sagittal plane or midline of the body. Many people wonder what are the differences between abductors and adductors.

Therefore, in this article we are going to tell you what the main differences are between abductors and adductors and what function each of them performs.

What is the abductor muscle

abduction muscles

The abductor is not limited to a singular muscle group in the body. However, when it comes to sports-related injuries, it is common for abductor injuries to primarily affect the leg, specifically the gluteus minimus and gluteus medius.

The leg abductors are responsible for facilitate lateral movement and maintain hip stability. Whenever you need to make a lateral movement, the leg abductors activate and contract. If there is any discomfort or pain in the leg abductors, it may hinder your ability to take a sure, steady step.

The abductor muscles can be seen in various parts of the human body. We are going to use as an example the abductor longus and abductor brevis muscles located in the hands. Similarly, the deltoid muscle plays a role in arm abduction, as does the supraspinatus muscle.

What is the adductor muscle

gluteus medius

The adductor muscles, as their name suggests, They are responsible for the execution of the adduction movement, which consists of bringing the extremities closer to the center of the body by contracting these specific muscles.

In terms of muscle fiber length, the adductors generally have a greater average length compared to the abductors. The magnitude of the force produced by these fibers It is directly proportional to its size and cross-sectional area.

Within the lower extremities there are three crucial muscles responsible for adduction, which is the movement of the thigh toward the midline of the body. These muscles, namely the adductor magnus, longus and brevis, are connected to both the bones of the pelvis and the femur, forming a network of strength and stability.

Differences between abductors and adductors

Difference between abductors and adductors

The muscles in question have both similarities and differences. After individually defining the function of each type of muscle, it is evident that there are both similarities and differences between them. Both types of muscles contribute to body movement and have the ability to contract independently. Besides, The abductors and adductors are present in various regions of the body, including arms, hands, and legs. However, despite these shared characteristics, there are clear differences that can help identify them when the question arises.

There is a distinction in the axis of rotation. The key distinction lies in the contrasting functions of the abductors and adductors. The abductors perform the function of separating a specific part of the body from its central axis, and are mainly used for external actions such as propelling a ball by extending the arm. On the contrary, the adductors have the task of attracting a particular region of the body towards the central axis, facilitating internal movements.

Given the distinction of movements, it is evident that the muscles responsible must occupy separate regions. The abductor muscles can be found located on the outside of the thigh, while the adductors are placed internally to facilitate movement of the leg toward the axis.

Antagonist muscles

The lack of competition between these muscle groups is evident. They function as antagonists, each having a purpose contrary to that of the other. This phenomenon reflects the relationship between the biceps and triceps.

By virtue of their opposing functions, these muscles allow us to achieve an impeccable balance, both mechanical and physiological, when moving away from and towards the central axis of the body. The abductor and adductor muscles of the hip, known for their importance, especially in conventional sports like football, they often suffer from injuries in this specific region.

The presence of the abductors is more pronounced within the body. When examining the muscles of the leg, it is evident that there is a clear variation in the total number of muscles that make up this area. Specifically, there are six muscles responsible for leg abduction: gluteus maximus, sartorius muscle, tensor fascia latae, gluteus medius, gluteus minimus and piriformis muscle. On the contrary, the adductors of the leg add one less and consist of five muscles: adductor magnus, adductor brevis, adductor longus, gracilis muscle and pectineus muscle.

Abductor and adductor machines in the gym

There are machines known as abductor/adductor machines that specifically target the muscles responsible for separating and bringing the hips together, which includes both the inner and outer thighs. The key distinction between these machines lies in the direction of force that must be applied.

The adductor machine targets the muscles responsible for bringing your legs together. To use the machine, place your legs outside the supports, with the pads resting on the inside of your ankles or knees (depending on the design of the machine). This exercise specifically targets the muscles involved in hip approximation.

The abductor machine targets the muscles that open the hip by placing the legs inside the supports, with the pads located on the outside of the ankles or knees, depending on the design of the machine.

Is it myth or reality that doing high repetitions on the abductor machine will burn fat in your legs? The idea of ​​burning localized fat is a common misconception in the fitness world, but unfortunately, it is not possible to target specific areas for fat reduction. Simply put, performing a high number of reps on the adductor machine will not cause fat burning specifically in the inner thighs.

La Fat distribution in the body is determined mainly by genetics– Some people store fat in their thighs while others store it in their abdominal region. Similarly, when it comes to burning fat, each person's body follows a unique pattern based on their genetic makeup. In essence, specific exercises will not determine where you lose fat first. Instead, the key is to combine exercise with a healthy, balanced diet.

I hope that with this information you can learn more about the differences between abductors and adductors.
