Abstract : During 1960-1963, the Civil Aeromedical Research Institute (CARI) conducted a broad spectrum of biomedical evaluations on a large number of air traffic control (ATC) students. Approximately 1270 of these students (20-50 years of age) underwent biodynamic evaluation of physical fitness. From these data, the relationships of maximum oxygen uptake (MVO2/Kg bw), resting SBP and DBP to age and the FRWI (an obesity indicator) were examined. General data trends indicated an increase in SBP and DBP with age and the FRWI. The MVO2/Kg bw showed a general trend of decrease as both age and the FRWI increased. In 1970, approximately 475 of the original 1270 ATC students possessed current airman medical certificates. An average age increase of 8.3 years had occurred. Relevant data from the current aeromedical certification files were examined. The average weight gain was approximately nine percent. The 1970 resting SBP and DBP also increased with both age and the FRWI. The percent incidence of the 400 pathology code, as well as resting exercise and recovery heart rates, increased with age and the FRWI. An overall pattern has emerged which indicates an advancing relative susceptibility to coronary heart disease (CHD) in those individuals with a combination of advanced age and obesity. (Author)
