Flexibility: The ability to bend and extend the joints at full / normal range of motion (depending on each joint). By such definition, flexibility is the ability of the neuromuscular system to efficiently move a joint within a full range of orbit. The term flexibility refers to the joints which refer to the non-contracting elements of the joints (bones, joints, ligaments, etc.) - that is to say, the ability of the joints, which, however, largely depends on neuromuscular fusion and muscle elasticity.
Dynamic is characterized the flexibility of the joints during movements. The term "specific" refers to the flexibility required to perform specific movements and activities.
Pliability: A term often confused with flexibility because in Modern Greek dictionaries and ancient Greek literature, the terms flexibility and pliability are given synonymously (opposite: stiffness). However, the concepts of flexibility and pliability in the science of physics are distinct and more commonly found in the literature, the term flexibility refers to the joints and relates to non-contractual elements of the joint, while pliability is a broader term that includes both flexibility and elasticity (associated with contractile articulation and ability to stretch muscles, tendons, ligaments and skin).
Elasticity: The ability of soft tissues (muscle tissue, connective tissue, tendons, skin) to return to the length of rest after stretching. By such a definition, elasticity is the ability of the soft tissues surrounding a joint to heal in tension without interference or resistance and then relax and return to rest.
Muscle Elasticity: The ability of muscles to elongate / stretch under the influence of a force and return to their normal length after this force has been removed. Muscle elasticity depends on the articular flexibility (non-contractile elements) and the elasticity of all the soft tissues of a joint.
Flexibility: A term often confused with flexibility because in Modern Greek dictionaries and ancient Greek literature, the terms flexibility and flexibility are given synonymously (opposite: stiffness). However, the concepts of flexibility and flexibility in the science of physics are distinct and more commonly found in the literature, the term flexibility refers to the joints and relates to non-contractual elements of the joint, while flexibility is a broader term that includes both flexibility and flexibility. and elasticity (associated with contractile articulation and ability to stretch muscles, tendons, ligaments and skin).
Mobility: A broader term that includes both flexibility of the joints and stretching ability of muscles, tendons and joints.
Agility: The ability to consciously and purposefully perform movements with the necessary and ideal range of motion of the participating joints. General agility refers to an average level of agility in all the joints of the body, while specific agility refers to the requirements of a particular sport, e.g. basketball, or other specific physical activity / exercise.
Plasticity: The tendency of soft tissues to adopt a new and longer length after removing the force that permits them.
Shortening: Adaptive reduction of the length of the muscle or other soft tissue that crosses a joint, which results in a reduction in the normal range of motion of that joint. When a muscle or group of muscles is shortened ("gathered") in a joint, then they, the muscle or muscle group, are in constant contraction (hypertension) and do not rest, while their competitor is usually dilated and weak and can to be injured more easily.
Muscle Stretching: The special mobilization/ technique / method by which we strive to lengthen a muscle group with the primary aim of avoiding or treating its shortening and maintaining its elasticity.

Always remember: Other muscle flexibility (related to contractile joints), other articular pliability (related to non-contractile joints), and other physical pliability (broader term that includes both flexibility and flexibility). These concepts are inextricably linked, yet they are not identical!
