Eccentric Exercises Like Treadmill Walking Are Used for Strengthening or Rehabilitation Programs

Writer:realleaderfitnessDate:2016-12-21 09:43:37
Physical exercise can be characterized by its duration, its intensity and the mode of contraction of the muscles involved. The concentric mode can be defined as muscle shortening during contractions due to the higher muscular torque compared to the external load (e.g., lifting a load, uphill walking/running). In contrast, an eccentric mode occurs when the external load is higher than muscular torque or during action against gravity (e.g. down stairs, jump landing, downhill walking/running) leading to muscle lengthening during the contraction. Eccentric contractions differs from concentric ones in terms of the production of higher torque for both upper and lower limbs, adding to a lower energy cost for several locomotor exercises, such as treadmill walking, running or cycling, performed at the same mechanical workload. The exercises involving eccentric contractions may be of interest for patients with disabilities. For example, it has been shown that the higher muscular work achieved during eccentric exercises resulted in more-efficient performance in people with multiple sclerosis and Parkinson’s disease. Locomotor exercises with an eccentric component such as downhill walking/running are used for strengthening or rehabilitation programs.
