Force – the important physical quality of the person necessary both in sport, and in everyday life. Force indicators in weightlifting, in powerlifting, in shot put, in the armwrestling and in Greco-Roman wrestling where it is necessary to counteract external resistance due to muscular efforts, or to overcome it are especially brightly shown. How to define the muscular strength?
Instruction
1. It is possible to define the muscular strength by dynamometers of various design. The muscular strength of the brush is defined by Colin's dynamometer. The dynamometer is put on the palm and contracts fingers with maximum effort. The result on the score-board is also force indicator. At different provisions of the elbow joint the muscular strength of the brush changes. She will be above in the free family way of the elbow joint with the corner of 160-170 degrees in relation to the shoulder. In the bent state (10-15 degrees) the indicator of force will decrease, and in most unbent (190-200 degrees) - will become minimum. According to numerous researches, weight-lifters possess the highest rates of force. The Stanovy dynamometer measures strength of razgibatel of the trunk. It is possible to measure by complex dynamometer installations indicators practically of all large muscles of the person: sgibatel and razgibatel of the hip, muscles of shoulders, sgibatel of the trunk, etc. Dynamometers equip sports clinics for observation of dynamics of growth of physical indicators of athletes.
2. In the conditions of the gym hall the dynamic muscular strength is defined by the maximum indicators in concrete exercise. In weightlifting the maximum force comes to light in two competitive exercises – breakthrough and the push. In powerlifting – in the bench press, squat and stanovy draft. Load of muscles in two sports differs, to execute breakthrough, it is necessary to give still acceleration to the apparatus, to show the explosive strength.
3. If you not the beginner in the raising of weights and regularly visit gym at least month, then can measure the dynamic muscular strength independently. At first well warm up with the empty signature stamp (make 10-12 repetitions), then gradually add weight on the post and reduce the number of repetitions. When you feel that the weight of the post is close to limit, carry out on 1 repetition and gradually make up the weight disks with each new approach. Surely use the safeguarding in such exercises as squat and the bench press. The safeguarding is carried out by the trained athletes from two parties. When performing squats and stanovy draft surely put on the belt and keep direct position of the back.
