title: Serum uric acid, cholesterol, and psychological moods throughout stressful naval training.
abstract: Navy recruits, all 51 volunteers for a preliminary underwater demolition team (UDT) training program, were followed through 4 weeks of training; 27 men passed and 24 failed the training course. Serum uric acid and serum cholesterol levels, as well as psychological moods data were collected on all volunteers at the start of training and at the end of each of the four training weeks. Men who passed training were compared to those who failed. In addition, these same measures were carried out with a control group of 66 naval recruits. Pre-UDT trainees who passed the program demonstrated high levels of positive moods, early peaks in serum uric acid level, and stable serum cholesterol levels throughout training. These findings supported previous work with successful UDT trainees. Pre-UDT trainees who failed the program demonstrated intermediate levels of positive moods, a midtraining period peak in serum uric acid, and a significant rise in serum cholesterol during the final 2 weeks of the course. The serum cholesterol rise seen during a period shortly prior to failure substantiates previous findings. A comparison group showed low levels of positive moods, an initial peak in serum uric acid, and stable serum cholesterol levels. Two mood scales had siginificant correlations with serum uric acid for only men who passed training. A motivation scale, given at the start of training, correlated with serum uric acid levels for men who failed training.
