Identify and briefly discuss the two types of training methods used to improve muscular strength.

What will be an ideal response?


Two types of training methods are used to improve strength are isometric (static) and dynamic (previously called "isotonic").• In isometric training, muscle contractions produce little or no movement, such as pushing or pulling against an immovable object. Isometric training does not require much equipment. Because strength gains with isometric training are specific to the angle of muscle contraction, this type of training is beneficial in a sport such as gymnastics, which requires regular static contractions during routines.• In dynamic training, the muscle contractions produce movement, such as extending the knees with resistance on the ankles (leg extension). Dynamic training is the most popular mode for strength training. The primary advantage is that strength is gained through the full range of motion. Most daily activities are dynamic in nature. We are constantly lifting, pushing, and pulling objects, and strength is needed through a complete range of motions. Another advantage is that improvements are measured easily by the amount lifted.
