“…Although muscular efforts are involved both in exertion of static strength and in dynamic work, one can not be predicted accurately from the other, and training of one may not much affect the other as discussed by Asmussen, Hansen, and Lammert, 1965;Ball, Rich, and Wallis, 1964;Bender and Kaplan, 1966;Berger, 1962Berger, , 1963Berger and Henderson, 1966;Chui, 1964;Clarke, 1962Clarke, , 1968Colgate, 1966;Dern, Leverne, and Blair, 1947;Gentry and Randall, 1966;Harrison, 1963;Hunsicker, 1955;Ikai and Steinhaus, 1961;Kogi, Mueller, and Rohmert, 1965;Kroemer, 1967bKroemer, , 1969Martens and Sharkey, 1966;Mueller, 19962, 1964;Pearson, McGinley and Butzel, 1963;Petersen, 1962;Rasch and Pierson, 1963;Singh and Karpovich, 1966;Smith, 1964, andTornvall, 1963. Data on static force capabilities should not be used for equipment evaluation if dynamic work is to be periormed by the operator.…”
