The distinctive force of speed

 It is the ability to perform movements with resistance at the level before the maximum and at a high speed.

The distinctive force of speed

        The force marked by velocity is the ability of the muscular nervous system to overcome resistance with the greatest possible shrinkage speed (Fray 1977, Harrah 1976), and the force distinguished by speed varies with the physical limbs involved in the movement (arms, legs). An athlete may be very fast with his arms and not necessarily have the same advantage for his legs (Smith and Hanger 1989).
      According to (Maafiaq), the force characterized by speed during play, and in exercises that combine strength and speed are sometimes called explosive power, this means the ability to develop maximum forces in a short time.

Definition of force of speed:

      Speed ​​power is defined according to (Jalal Mohammed Abdel-Wahab) that muscles work at their maximum strength in the shortest possible time and can be represented by the following formula: Muscle capacity = capacity x speed
      To acquire this property, there is a need for harmony and harmony between the muscle strength and the speed of the muscles used, and then in order for the individual's muscle strength elements to be available
     A- A high level of muscle strength
    B- High level of speed.
    C- A high level of motor skill whose causes are created by the integration of strength and speed.
     

    Distinguished strength components with speed

 This characteristic consists of a combination of the characteristics of force and velocity to prepare them when the beginner should begin with the characteristics of general endurance, and this is to reach the degree of adaptation to the pneumatic mechanics, and then the characteristics of the force must be adapted (explosive force, thrust force, starting force), then the velocity characteristics (average speed Speed, extreme speed) and finally the skill that combines both strength and speed.

 Explosive force

 It is the ability to accomplish a maximum increase in strength in the shortest possible time, i.e. an increase in strength where the time unit is the dominant force and the explosive force depends on the speed of contraction of the motor units with rapid muscle fibers and the strength of the contraction of the interfering muscle fibers.

    Starting strength

We can enter it under the type of explosive force, where the ability to accomplish a maximum increase at the start of muscle contraction is considered, and the starting strength requires improvement in movements that require a large initial velocity, it is characterized by the ability to enter the largest possible number of kinetic units at the same time during the beginning of the contraction, the comparative force was to be Its achievement is weak, the starting force is the dominant one, and if the load increases, the entry of the motor units is fixed and determined by fast muscle fibers, so the explosive force is the effective (to convert the starting force into an explosive force), and in the case of a very high load, the maximum force here is to interfere.

     Physiological properties of force characterized by velocity
Since the force characterized by velocity means the ability of the muscular nervous system to produce rapid strength, then there is a merging and linking between the properties of force and velocity in one component, that is, the achievement and implementation of movements is coordinated between the compounds of force and velocity at the same time.
According to (what is lackluster), the efficiency of the link between strength and speed enables it to develop the voluntary will of the muscles that exude the first role during performing movements that require a sudden adjustment of the work of resistance, and according to (Bohr and Schmid) in 1981, the physiological factors that affect the characteristic of strength characterized by speed.
