The Relationship between Leg Strength, Leg Endurance and other Body Measurements

摘要

The importance of leg strength and the ability to exert constant force in the event of mechani¬cal failure were considered important factors in the selection of heavy bomber pilots for World War [[. This study was done at the AAF School of Aviation Medicine, Randolph Field, Texas in an attempt to determine whether height and weight standards for heavy bomber pilots could be reduced without materially modifying leg strength and leg endurance.nNo literature' was found which described a method of measuring the forceful extension of the leg and hip with the subject in a sitting position, nor was a method found for measuring the amount of time a pre-determined amount of force could be exerted. Thus, it was necessary to design and construct a special apparatus and test procedures that were considered to be suf¬ficiently reliable for use.
