      <subfield code="a">The study investigated the effects or frequency and technique of repetitive lifting of a barbell on the relationship between mean power output and energy cost in 9 male power-lifters. Oxygen uptake was measured directly and continuously and power output was deduced from film analysis using an inverse dynamic analysis. Power output and oxygen consumption were significantly greater for squat than for stoop lifting at the same frequency</subfield>
