Structural Kinesiology Basic Biomechanical Factors & Concepts 3-29 Torque and length of lever arms • In humans, contracting muscle applies an eccentric force (not to be confused with eccentric contraction) to bone upon which it attaches & causes the bone to rotate about an axis at the joint • Amount of torque is determined by Faculty of Kinesiology, Engineering, Medicine and Veterinary Medicine, University of Calgary, Calgary, AB, Canada; For the past 60 years, muscle contraction had been thought to be governed exclusively by the contractile filaments, actin, and myosin. Kinesiology is the study of the anatomy and physiology of body systems that create movement. The authors argued that the application of elastic kinesiology tape stimulated muscle spindles and facilitated muscle contraction via stretch mechanoreceptors. insertion. Finally, high-velocity ballistic training induces specific neuromuscular adaptations that occur as a function of the underlying neurophysiological mechanisms that subserve ballistic movement. Palpate the quadriceps as your partner Climbs up the stairs When are the quadriceps most active? Eccentric contraction Kinesiology takes advantage of this to provide exercise and stimulation to balance one muscle's stretch with another's contraction. Isotonic actually means 'same tension', which is not the case with a muscle that changes in length and natural biomechanics that produce a dynamic resistance curve.
