KNES 1000 Lecture 18: Kin lecture 17 & 18
Document Summary
Lecture objectives: de nitions of strength, differences between absolute and relative strength, identify ways to in uence strength ! Muscle function forms the basis of these physical components o. Strength: power (speed strength) o endurance (muscular) o flexibility. When muscles contract they generate force: o which we call. The ability to perform maximal voluntary muscular contractions in order to overcome powerful external resistances (movable or xed: common measurement of strength is: ! The greatest force that can be exerted during one repetition for a given contraction for a given contraction of muscles. Measure ability of the muscles in 1 contraction (1rm), single resitiance ! Grip strength, barbell clean, bench press: newton"s 2nd law force = mass x acceleration ! The heaviest weights of all lifted by athletes in the heaviest weight categories: maximal and absolute strength. The greater the active body mass, the greater the maximal or absolute strength.
