Lengthened muscles, also known as eccentric contractions, are muscles that are pulled long to engage. This occurs when the force exerted on the muscle exceeds the force developed by the muscle, resulting in the muscle lengthening as it works to absorb mechanical energy. Lengthening muscles is important for improving balance and flexibility, as it works the entire muscle from insertion to attachment, allowing smaller and weaker muscles to be engaged. This is in contrast to shortening or gripping muscles, which tend to activate only the stronger and more easily activated muscles. While the term long, lean muscles is often associated with practices like yoga and pilates, proper resistance training with eccentric contractions and full ranges of motion is more effective for actually lengthening muscles.

Lengthened muscles improve balance
On the other hand, shortening or gripping muscles tends to turn on the stronger and more easily locatable muscles, but not the weaker, smaller or harder-to-find muscles. Overusing the strong muscles allows some of the smaller and weaker muscles to be underutilised, creating more and more muscular imbalance over time.
Lengthening the leg muscles helps improve balance. When we pull our muscles long, we work with gravity to create a grounding effect; our bodies and limbs start pressing down through the floor instead of pushing against it. This length creates better balance because of the strong connection through the floor. It is rather like how support beams for skyscrapers, or roots of a tree, are drilled into the earth, which allows them to be tall while providing a connection that keeps them from being blown over in the wind.
The concept of lengthened muscles is also important for dancers, who lengthen their spine, arms, legs, fingers and toes to create a look of long and lean muscles. Lengthened muscles help dancers maintain their flexibility while engaging their muscles to create high extensions. It is also how ballet dancers move quickly and with great ease while performing difficult steps, as well as how they balance for so long.
Muscle length is also described as flexibility, indicating the ability of the muscle to be lengthened to the end of the range of motion across the joint. Lengthening muscle contractions have a surprisingly long history in physiological studies. For example, in 1882, Fick observed that a muscle could exert greater force when stretched while contracting. Fifty years later, Hill reported that there is decreased energy liberation in a muscle that is stretched during a contraction.

Lengthening vs. shortening muscles
A lengthened muscle is a muscle that is pulled long to engage. Lengthening a muscle involves pulling it from end to end, similar to how a clothesline is pulled tight. This works the entire muscle, from insertion to attachment, rather than just a portion of it. Lengthening the muscles also creates a stretch, allowing for greater flexibility and space in the joints, which improves balance.
Shortened muscles, on the other hand, occur when we contract or tense our muscles, causing them to pull short and grip. This tends to engage only the stronger, larger, and more easily activated muscles, while the smaller and weaker muscles are underutilized or turned off completely, leading to muscular imbalance.
An example of engaging a lengthened muscle is reaching your arm long out to the side of your body to engage your bicep, instead of trying to flex it. Lengthening the leg muscles also helps improve balance by working with gravity to create a grounding effect.
Training at longer muscle lengths has been found to promote more muscle growth than training at shorter muscle lengths. This is because biarticular muscles, such as the hamstrings, allow for the manipulation of multiple joints to change the length that the muscle is trained at. For example, seated leg curls were found to cause more hypertrophy in all the biarticular hamstring muscles in untrained lifters compared to lying leg curls.
Additionally, some studies have suggested that muscle fiber lengthening prior to shortening may enhance the total work done in a cycle. For example, work loops performed in isolated fish muscles showed maximum work when there was some active lengthening prior to shortening, as the increase in force and work during shortening outweighed the energy dissipated during lengthening. Similarly, bird pectoralis showed activation, lengthening, and force development during wing elevation, indicating that a "countermovement" is favorable for net power and work production in flight.

Muscle length and flexibility
When a muscle is lengthened, it is pulled long to engage, similar to how a clothesline is pulled tight from end to end. This type of muscle contraction is known as an eccentric contraction, a term introduced by Asmussen in 1953. Eccentric contractions occur when a muscle is actively lengthened during normal activity, such as walking or running. For example, when the heel strikes the ground during walking, the quadriceps muscles actively lengthen to control the movement of the knee.
The lengthening of muscles is important for improving balance and flexibility. By pulling the muscles long, we work with gravity to create a grounding effect, improving stability and posture. This is particularly evident in ballet dancers, who train to lengthen their muscles to maintain flexibility and achieve high extensions. Additionally, lengthening contractions play a significant role in locomotion. During activities like running, jumping, or hiking downhill, muscles lengthen to absorb and store energy, enhancing power output and improving overall performance.
It is important to note that the ability to lengthen a muscle is influenced by factors such as the specific muscle, its training status, and the amount of time dedicated to training. While muscles cannot drastically change in length, proper training methods can lead to noticeable lengthening. For example, strength training, resistance training, and dynamic movements that challenge the full range of motion are more effective for lengthening muscles than static stretching alone.
In summary, muscle length and flexibility are interconnected concepts that involve the physical length of a muscle and its ability to extend through a range of motion. Lengthening muscles through appropriate training methods can improve balance, flexibility, and performance in various activities. However, it is important to understand the limitations and trade-offs associated with muscle lengthening, as altering muscle lengths can impact coordination and speed.

Eccentric contractions
An eccentric contraction is a type of muscular contraction that appears paradoxical: the muscle contracts as it lengthens. Eccentric contractions are harder on the muscle, leading to more soreness. They are also known as "negative work" because they absorb energy.
During an eccentric contraction, muscle tension increases as it lengthens to resist a force that attempts to overstretch it. This is the opposite of a concentric contraction, where a muscle shortens as it contracts. An example of an eccentric contraction is the lowering phase of a bicep curl.
Eccentric exercises are commonly used in rehabilitation to stimulate muscle growth and increase strength and mass in athletes. They can also improve balance by creating a grounding effect through the strong connection to the floor.

Lengthening muscle contractions and locomotion
Muscle length is often described as flexibility, indicating the ability of the muscle to be lengthened to the end of its range of motion across a joint. Lengthening muscle contractions, also known as eccentric contractions, occur when the force exerted on a muscle exceeds the force developed by the muscle, causing it to lengthen and absorb mechanical energy. These contractions are characterised by high force production and require very little metabolic energy. During locomotion, eccentric contractions result in braking and the storage of elastic recoil energy.
An example of eccentric contractions in locomotion is walking. As the heel touches the ground and the knee bends or straightens, the quadriceps muscles actively lengthen to accommodate the movement. Similarly, when lowering something heavy, the muscle lengthens to shift the weight to a different position while remaining contracted to manage the weight.
The importance of lengthening contractions in locomotion has gained increasing attention in recent years. Studies have shown that during the swing phase of a stride, the hamstring muscles undergo monotonic lengthening. As walking speed increases, the amplitude and degree of synchronisation of this lengthening contraction also increase.
In individuals with spasticity, disturbances in the activation of muscles during functional movements have been observed. Abnormalities in the lengthening contractions of the hamstring muscles during the late-swing phase include reduced muscle-tendon excursion, increased maximum EMG amplitude, and a loss of positive correlation between lengthening velocity threshold and walking speed.
Lengthening muscles through exercises such as stretching can improve flexibility and balance. It works the entire muscle instead of just a part of it, allowing smaller and weaker muscles to contribute equally. This helps to prevent pain, improve joint mobility, and protect joints from wear and tear.
