The resistance training is a form of training of the force in which each effort against a specific force is made opposition generated by the resistance (the resistance that is to say, to being pushed, being expressed, stretched or doubled). The exercises are isotonic if a part of the body moves against the force. The isometric exercises are a part of the body if it still stays against the force. The resistance exercise is used to develop to the force and the size of skeletal muscles. Made correctly, the resistance training can provide important functional benefits and improvement in the general health and well-being.
The objective of the resistance training, in agreement with American Sports Medicine Institute (ASMI), is “gradual and progressive to overload the musculoskeletal system reason why more fort becomes.” The investigations demonstrate that the training of regular resistance to fortify and to strengthen muscles and to increase the mass bony. The resistance training does not have to be confused with the rise of weights, rise of weights or bodybuilding, that are the competition sports affect to different types from training of force with the non elastic forces like the gravity (Plyometric training with weights or exercises) and not a resistance immovable (isometric exercises, generally the muscles of the own body or a structural characteristic, as a frame of the door). An ample range of movement is important in the resistance training because the muscular overload takes place only in the specific joint angles, where works the muscle.
The resistance training can be made using several types of exercise equipment or:
• The resistance bands
• Exercise machines
• Swimming machines
the study “metabolism of the fat and the exercise of acute resistance in the trained men” carried out by the East Carolina University found that the resistance exercise is more beneficial than the Aerobic exercise to lose fat. The intention of the study was to see how the resistance exercise can contribute to the improvement of the corporal composition.
