Document Summary
Chapter 6: assessment of muscular fitness (pages 153 to 180) What are 2 components of muscular fitness: muscular strength & muscular endurance. What do adequate levels of muscular fitness lessen: the chance of developing low back problems, osteoporotic fractures, musculoskeletal injuries. Isokinetic: a maximal contraction of a muscle group at a constant velocity through the entire rom of the joint. Isokinetic contraction: maximal contraction of a muscle group at a constant velocity throughout entire range of motion. Isometric contraction: type of muscle contraction in which there is no visible joint movement; static contraction. Isotonic contraction: type of muscle contraction producing visible joint movement; dynamic contraction. At which angle is the strength of the knee flexors maximal: the strength of the knee flexors is maximal at 160 to 170 . At which angle is the strength of the elbow flexors maximal: the strength of the elbow flexors is maximal at 56 .
