b) a second viscosity (v2) in response to a second motion by the subject that exerts a second force (F2) upon the at least one support element, wherein F2 is greater than F1 and v2 is greater than v1 such that the at least one support element produces a greater resistance to the second motion than to the first motion.

3. The article of claim 1, wherein the at least one support element comprises an elastomeric polymer.

4. The article of claim 1, wherein the elastomeric polymer forms a foam matrix comprising the non-Newtonian material.

5. The article of claim 4, wherein the non-Newtonian material is a shear thickening non-Newtonian fluid.

6. The article of claim 1, wherein the at least one support element comprises a pouch encapsulating the non-Newtonian material.

7. The article of claim 1, wherein the at least one support element is configured to provide resistance to movement of at least one of a muscle, a joint, or a bone of a subject, wherein the resistance increases with increasing force of the movement.

8. The article of claim 1, wherein the at least one support element comprises at least one of:

a) a neck support element;

b) a thigh support element;

c) a shin support element; and

d) a spine support element.

9. The article of claim 8, wherein the at least one support element comprises a neck support element comprising a penannular collar member that is anatomically complementary with a neck of the subject.

10. The article of claim 8, wherein the at least one support element comprises a neck support element comprising a force-reactive polymer positioned around a rear and lateral sides of a neck of the subject.

11. The article of claim 1, wherein the at least one gripping element is configured to exert at least one of a normal and a tangential force upon the body surface of the subject to reduce shifting of the article across the body surface of the subject.

12. The article of claim 1, wherein the at least one gripping element comprises a surface texture configured to exert a tangential force upon the body surface of the subject.

13. The article of claim 1, wherein the at least one compression element is configured to provide stress support, load transfer, fatigue relief, or any combination thereof to the subject.

14. The article of claim 1, wherein the at least one compression element is configured to exert a force on at least one of a muscle, bone, or joint of a subject throughout a full or partial range of motion.

15. The article of claim 1, further comprising at least one adjustable tension element.

16. The article of claim 15, wherein the at least one adjustable tension element comprises at least one of a chest tension element, an abdominal tension element, a waist tension element, a thigh tension element, or a shin tension element.

17. The article of claim 1, wherein the at least one compression element comprises a polymeric material or composite material.

18. The article of claim 1, wherein the at least one compression element comprises silicone, nylon, lycra, rubber, neoprene, vinyl, polyurethane, or any combination thereof.

19. The article of claim 1, wherein the article comprises a long-sleeve shirt, a short-sleeve shirt, a no-sleeve shirt, a pair of pants, or a full body suit.

20. A method for forming an article wearable by a subject, comprising:
