abstract="After mentioning today's practice in handling the problem of setting rest allowances, definitions are given for the terms of fatigue, recovery and degree of fatigue. Discriminating between stress and strain leads to the possibilities in determining both. Measurable effects of fatigue in static muscular work are discussed. The procedure for determining optimal working rhythms by measuring stress and strain in static muscular work is explained.<p /> <p>Language: en</p>",
