The fundamental principle of DCT™ is to strengthen the weak, sub-activated tissue, and open and expand the strong, dense tissue. By following this principle, DCT™ Practitioners and clients are able to restore balance to the musculoskeletal system, changing the way they move and reducing wear and tear on the body. This is achieved primarily by using the eccentric muscle contraction – contracting a muscle while it lengthens – which is inverse to the more commonly understood concentric contraction (e.g. biceps curl). While concentric contractions help to build strength in muscles, they can also contribute to the development of excess muscle tension. In addition to the concentric contraction, some other causes of tension imbalance include physical injuries, lengthy sedentary positions, and emotional trauma. While excess muscle tension can reduce flexibility, create “knots”, and decrease range of motion, thus reducing functionality, reduced tension and weakness from lack of use or traumatic injury can also cause joint alignment issues that lead to chronic pain and reduced function.
DCT™ exercises incorporate all three muscle contractions, seamlessly moving through the concentric (activation), isometric (transition) and eccentric (tension balancing) phases in order to address both weakness and excess tension at the same time. DCT™ Practitioners use proper biomechanical alignment (i.e., posture) as a guide to hone in on structural alignment issues caused by excess or deficient tension. Practitioners then follow the tension patterns through clear communication with their clients, utilizing their understanding of how and why tension, or the lack thereof, leads to postural imbalances and other ailments.
