Training in Sports Term II Strength & Methods

Strength

• It is the ability of muscles to overcome resistance.

Dynamic Strength

• as it is related to movement it is called as isotonic strength.

• there is diminishing tendency in dynamic strength. In pullups/ pushups after certain count muscles refuse to do work even one pullups/ pushups.

• types of dynamic strength are as given below

Maximum Strength, Explosive Strength, Strength Endurance

Maximum strength

•  ability to work against maximum resistance is known as Maximum strength.

• Maximum strength. is not used in majority of sports where heavy resistance is taken.  

• This type of strength is required for short period of time.

Example: takeoff in long jump 

Explosive strength

• is the ability to overcome resistance with high speed. 

• we can say that it is a combination of of strength and speed.

• it is mostly used in sprint start and weight lifting.

Strength Endurance

• As understandable from its name it is a combination of endurance and strength.

• We can say that it is the ability resistance to act against resistance under the condition of fatigue. 

• Generally used in long distance races

Static Strength

• Static strength also called as isometric strength also

• We can say that it is the ability to act against resistance.

• neither this type of strength is used nor usually applied in sports but in Weightlifting it is used in phases.

Isometric

• This exercise is not visible therefore it cannot be observed.

• in this work is performed but not seen directly.

• a group of muscles are straight more than the other muscles group.

• during exercise muscles to not change their length.

• muscles make feel a slight tremor me if exercise done for long duration of time.

• we feel that we had done lots of exercise but scientifically it is zero but the expenditure of energy is same.

example: pushing a wall 

• benefit these exercise acquire list time and can be performed anywhere.

• zero no equipment is required to do these exercises.

• for rehabilitation purpose these exercise are so valuable.

Isotonic

• In this movement can be seen directly.

• work done in these exercises are scientifically not zero.

• it tone up muscles.

• muscles become flexible and length can be increased by these exercise.

• have a great value in the field of sports.

• can be done with or without technical equipment.

for example: callisthenic exercises & Weight training are the best examples

Isokinetic

• Developed by Perrine in 1968. 

• in this contraction of muscles apply maximum force throughout complete range of moment
