What is repetition?

In fitness, repeating is defined as the performance of a single movement or exercise through a wide range of movement. The predetermined number of repetitions performed and in a rhythmic manner is called training set and the amount of weight or resistance used for exercise is called burden . Together, these three variables affect the intensity of resistance training.

There is an inverse relationship between repetition and burden within these factors. The heavier loads will require a lower number of repetitions, while lighter loads allow a higher number of repetitions. Depending on the targets of the training, repetition and load can be adjusted along a continuum with high load and low repetition at one end and on the other side on the other. The load is often expressed as a percentage of maximum repetition or 1rm - the maximum weight that the athlete can raise for a single repetition of particlear exercises. In most skeletal muscles there are two different types of muscle fibers, in different proportions. SpadeScrews are associated with short, intense explosions of activity and are most able to increase size and strength. Their counterpart, slow fibers twitching, are used for low intensity, long -term activities and tend to remain relatively constant.

The lower number of repetitions with or near or near it will tend to increase muscle strength. Training of muscle strength usually uses repetitions between one and six, mostly activate the rapid muscle fibers of twitching. Power trainings are often performed by athletes training for sports goals such as those involved in sprinting and lifting energy.

To enlarge the size of muscle fibers, answers known as muscle hypertrophy , is usually repeated in the range of six to 15 in the training set. This range usually activates a mixture of muscle fiber types and promotes the development of both strength, so stamina. The lower end of the range will tend to stimulate more fast fibers Twitch, promote muscle strength and size. Higher repetition also causes hypertrophy, but hires a higher percentage of muscle fibers with slow jerking, causing muscle endurance and cardiovascular efficiency.

Repeat more than 15 on the set normally supports muscle endurance and cardiovascular condition almost exclusively. Exercise, including a high number of repetitions, stimulate the fibers of slow jerking, leading to a very small change in the size and shape of the muscle abdomen. However, this type of exercise promotes increased energy metabolism in the muscle, as well as increasing the ability of the cardiovascular system to supply oxygen and nutrients to the work muscles.

The number of repetitions carried out for exercise set during training depends on a large extent on personal goals, genetics and basic level of fitness. For balanced training and overall condition, combination of strength, strength and endurance training during the week,Months or even a year will benefit from the benefits of all three intensities and lead to a well -developed basic power.
