It is necessary to understand the different types of muscle actions that occur during resistance training. It takes a step further, to understand how to use these procedures in the /, sports or any activity. Understanding of muscle action may create a greater sports performance and / or fitness. Resistance training calls for amendments to the muscles that lead to higher levels of athletic performance, smaller, sexier physique, and a general feeling for better health. Muscle actions reflect these changes occur, despite the fact that all the work is different in nature.

There are three types of actions in the muscles, eccentric, concentric, and isometric. Procedures only muscle concentric and eccentric is dynamic. This is because the procedures and biochemical changes in muscle length 2 relations of tension while power is applied (1). During training, the majority are developing resistance exercises and devices to allow athletes and lifters to perform all of the work of eccentric muscle, and united in the order of each other. There is a positive relationship between training and fitness / sports performance because the movements of real life and often require two procedures in the order.

When the eccentric muscle action force generated in the muscle and skeletal muscle fibers lengthen during contraction. More preferably, applied to slow down the power to delay or part of the body or the body. Imagine Crouch to squat, it is eccentric muscle action. And eccentric muscle work must be in terms of muscle growth during training. And even if it is necessary to work more dangerous than the eccentric muscle action of the three. The majority of non-contact injuries occur during eccentric muscle actions, as it usually generates a higher amounts of mechanical stress from concentric or isometric muscle actions. However, the NSCA provides that the high levels of mechanical stress results in greater amounts of muscle activation / growth (1). Muscle growth leads to resistance, strength and speed, speed, reduced injury, and fitness lean. Other side effects less convenient than eccentric training and muscle aches, fatigue, and inflammation. Can avoid these side effects if not done only concentric training.

Concentric muscle action is when you grow muscles and skeleton, and the provision of pressure, and / or use of force on the body and the muscle fibers shorten during contraction. Perception of a permanent squat, it is concentric muscle action. Concentric muscle actions are necessary in terms of athletic performance. These measures paid athletes in running, jumping, hitting, etc ... In a sport such as swimming, where the concentric muscle action procedures are only used while in the water because it does not involve gravity, we must use and develop the capacity of the largest power / output. Movements such as high tensile strength, arm dumbbell kidnapping, which usually does not require a concentric action may be useful to reduce pain while increasing muscular adaptation. However, most sports require athletes to use the muscle / tendon before stretching, known as the "stretch shortening cycle" which involves the work of the eccentric followed by the center's work.

Although eccentric actions lead to the adaptation of larger quantities or muscle growth, and training, centralized showed positive results. Recently, the study found that after eight weeks of training isokinetic concentric, and the participants and the size of the power of resistance has increased (2). This research study supports the training and the other directed centrally as a way to increase muscle strength, size and performance. Oriented is the additional benefit of reducing the concentrically trained muscle fatigue, and loss of power during repeated bouts, and pain.

Based training may be useful on the centrality of training during the season or weeks before the competition. The absence of pain and fatigue, and allows athletes to people as well as their adaptation to maintain sport specific training without losing muscle. However, in order to achieve maximum athletic performance or the performance of fitness training, and people should continue to engage in training, eccentric, isometric, and concentric. There is very little movement, if any at all, and that does not require all three procedures.

Here are some of the movements of the lower part of the body that lead to injuries lowered, and maximum muscle growth, and indulge in all three muscle actions:

The Squats (back, forward, or dumbbells) involved in a full range of motion (ROM), disk full and requires good technical progress.

One seat leg movements that require Squatsare athlete to squat on one leg until their buttocks rest on the bench, be sure to limit the amount of very lean forward to the front knee never passes the toes.

Here are some of the target concentric movements that can increase the output power with less pain, and loss of strength, and muscle fatigue:

And will Ropedrills are really heavy chains heavy concentric does not move until the imposition of force by the concentric muscle action.

High impact strength is the Olympic movements that require the player to an explosion raised the bar from the ground and shoot at the highest level possible in the upward movement until it passes the mid-section, the end of the pull bar allows the athlete to fall to the ground. Must be used for the Olympic Movement weight of the car, and should only be done after that I learned raised.

Please note that the athletes in the formation of concentric pattern is a great way to train the leadership of an event or contest. Is not justified in recent weeks, leading to pain than the competition. Looking for an educated and conditioning coach, strength, which includes the training season. And your goal should be to focus the work of concentric lifts to maintain or slightly increase the power and authority. However, it is always vital for the further implementation of the eccentric actions to ensure optimal performance, health and longevity.
