Do eccentrics build muscle?
The question of whether eccentric exercises build muscle has intrigued fitness enthusiasts and researchers alike. Eccentric movements, characterized by muscle lengthening under tension—such as the lowering phase of a biceband curl or descending into a squat—are not only integral to diverse training regimes but are also potent stimulators of muscle growth. This is because eccentrics are known to cause more micro-damage to the muscle fibers compared to concentric actions, where muscles shorten as they contract. This damage signals the body to repair and strengthen the muscle, potentially leading to larger muscle size over time.
How Eccentric Training Stimulates Muscle Growth
Eccentric training engages the muscles in a unique way, applying stress over a longer period and creating conditions that are ripe for muscle strengthening and growth. This elevated tension can increase the rate of protein synthesis and promote the activation of satellite cells, crucial for muscle repair and growth. Moreover, because one can typically handle heavier loads during the eccentric phase of an exercise, this form of training can profoundly impact muscle strength and hypertrophy.
The Role of Eccentric Exercises in a Balanced Workout Routine
Incorporating eccentric exercises into a balanced workout routine can optimize muscle development and enhance overall physical performance. Whether it’s through slow-lowering squats, focused dumbbell descent in curls, or controlled descent in pull-ups, these movements enrich the training spectrum. Importantly, diversity in training, including an emphasis on eccentric movement, can prevent plateauing, ensuring continuous progress in muscle building.

What is concentric vs eccentric?
Understanding the concepts of concentric vs eccentric actions is crucial for those engaged in any form of physical training or rehabilitation. These terms describe the two main types of muscle contractions that occur during any movement, each playing a vital role in developing strength, power, and muscle hypertrophy.
Concentric contractions happen when a muscle shortens as it exerts force. This type of contraction is often thought of as the «lifting» phase of an exercise. For example, when you raise a dumbbell during a bicep curl, your bicep muscle is contracting concentrically. The muscle fibers shorten, pulling closer together, which allows the movement against gravity or resistance. This phase is typically associated with the building of muscle strength and power.
In contrast, eccentric contractions occur when a muscle lengthens while under tension. This often misunderstood phase is sometimes referred to as the «lowering» phase of an exercise. Using the same bicep curl example, as you lower the dumbbell back to the starting position, your bicep is undergoing an eccentric contraction. Despite being under tension, the muscle fibers lengthen. This type of contraction is key for muscle hypertrophy (growth) and improving muscular endurance. Furthermore, eccentric training is often used in rehabilitation settings, as it can significantly contribute to the recovery of muscle strength and flexibility.
Are squats eccentric or concentric?
When delving into the mechanics of squats, it’s essential to understand the two key phases that muscle action encompasses: the eccentric and concentric phases. Squats, a fundamental exercise in strength training, leverage both these phases, thus stimulating muscle growth, improving strength, and enhancing overall fitness.
Eccentric Phase of Squats
The question of whether squats are eccentric or concentric begins with understanding the exercise’s movement. The eccentric phase occurs when you lower your body into the squat. During this phase, your muscles elongate under tension, absorbing energy as they resist the force of gravity pulling you downward. This phase is crucial for building muscle strength and increasing flexibility.
Concentric Phase of Squats
Conversely, the concentric phase of a squat takes place when you push your body back up to the starting position. During this phase, your muscles contract, exerting force to overcome the resistance. This action is what most people associate with muscle building and strength as it requires significant energy and power to execute, especially under added weight.
Thus, asking if squats are eccentric or concentric is akin to exploring two sides of the same coin. Both phases play integral roles in the biomechanics of squatting, contributing uniquely to the exercise’s effectiveness in building muscle, improving endurance, and enhancing overall physical health.
How often should you do eccentric training?
Eccentric training, a method where you emphasize the lowering phase of a lift, is an effective way to build strength and muscle, as well as aid in rehabilitation. But determining how often to incorporate this type of training into your routine can be a puzzle. Experts suggest that to reap the maximum benefits while minimizing risk, careful consideration of frequency is essential.
Generally, it’s recommended to integrate eccentric training into your workout regimen 1-2 times per week. This frequency allows for sufficient recovery, critical because eccentric exercises can lead to more muscle soreness and strain compared to concentric or isometric movements. Allowing your muscles to recover is crucial in preventing injury and ensuring continuous progress.
Variability in your training schedule is also key. If you’re someone who trains multiple times a week, consider dedicating a session or two to focus on the eccentric phase of exercises. This could mean performing slower, more controlled movements during your regular sets or incorporating specific eccentric-only exercises. It’s also beneficial to rotate the muscle groups you target with eccentric training, ensuring a balanced and comprehensive approach to muscle development.
