Static flexibility refers to the range of motion of human joints and their surrounding muscles, ligaments and other related organizations in passive stretching activities. Static flexibility exercises do not need active muscle activities, but only rely on external forces (such as peer assistance, gravity or the help of instruments) to stretch muscles.
Dynamic flexibility refers to the range of activities that can be achieved by active activities, so active muscle activities are needed.
The methods to improve flexibility include static stretching (active and passive), dynamic stretching, impact stretching and myofascial relaxation (massage).
Flexibility is usually measured by sitting forward, which mainly reflects the flexibility of the posterior thigh muscles and some back muscles. Flexibility of other joints and muscles is not included. Because of its simplicity, this action test is usually taken.
Action requirements: sit barefoot on the mat, with your legs slightly apart and close to the ground, with your toes facing up, and touch your body forward in the direction of your toes and keep it at the limit for 30 seconds.
Tools: cushion, timer.
Other types of flexibility assessment include Thomas test, passive straight leg elevation test, shoulder flexion, extension, pronation, supination and shoulder contact test. So we need professionals to cooperate with the test, so we won't do it here.
