Commenting on the studies, Dr. John M.

Dr. Fred W. Cash, professor of physical education at San Diego State College, Calif., organized an adult fitness program for men 57 to 64, many of whom had cause for concern for their own health. They took part in a training program with medical supervision. Several of these groups came to Boulder City in 1971, and again this year as Dr. Dills guinea pigs, to find out how older men adapt to hot temperatures after living in the milder temperatures of San Diegc. Dr Dill, who at 81 can outwalk most of his staff of young science students who help m the lab, is the founder of the fatigue lab at Harvard l mversity He came to Boulder City in 1932 to help solve several deaths from heat prostration that occurred in 1931, the first year of construction on Hoover Dam. The study included observations in the resting state, blood pressure and pulse rate, and observations during walks in the desert course set up on the grounds of the Bureau of Mines laboratory. Walkers were checked for rectal temperatures before and after the walks, sweat collection and body weight before and after In a study of workmen with 157 West 33rd South, Salt Lake heat cramps who were hospitalized, the nature of the lll- - Offices In: Denver, Las Vegas of sevDill insti- gate a walking program for Boulder residents. The walkabout, he said, would be preceded by a thorough physical examination of each participant. By testing the group we will be able to make an assessment of how well people living in Boulder City are adapted to exercise The walkers will be examined during the exercise and their physical condition will be assessed at the end of the project. Those who need it would be encouraged to get into a physical program. 0 Large Companies Small Companies See With the cooperation eral local physicians, Dr plans next summer to v LUSTED Lease PLAN For ness was established as a disturbance of electrolyte balance due to the loss of salt in the sweat.

Dr. Dill, else," quipped proves that boys, when they take girls out into the desert, shouldn't expect them to walk as fast or as far as thev do. Faithful workers on the staff are Maude and Mabel, the burros used in the labs study of environmental stress. Past tests of man versus the burro in the desert have shown that the quadruped goes farther and lasts longer. One study, in which man and burrow walked up and down a two percent grade side by side, showed the burro used half as much oxygen per kilo weight as the man. One reason for this. explained Dr. Dill, is the difference in physical design of man and burro. The less you raise the center of gravity in walking, the less energy you use." Other tests have included the measuring of the burro's metabolism at the end o( a walk, measuring the amount of oxygen used by collecting the expired air and measuring its volume and analyzing its composition. Mans salivary secretion fails after a few hours walk on a hot summer day, while the Boulder City burros, after 24 hours' rest without water, walked 10 hours more without water. Given water to drink, they rcpliud within 15 minutes nearly all the water lost in the previous 34 ,iours. It appears, concludes Dr. Dill, that while man and burro sweat at the same rate per unit of body surface, the burro conserves volume plasma while man loses a portmnate amount of water from the plasma Further comparison of Hie burro to man will be made next summer. Dr. Dill said, wilh special attention being given to the rate of dehydration of the animal compared to man !y GLASS-BELTE- D two-hou- tions, the men were able to afternoon four complete walks. In two of these walks the subjects drank nothing. The men lost four to five pounds. The senior San Diegans proved remarkably fit and were well able to cover three and miles during an hours walk m the sun the day after arriving here, Dr. Dill said, adding that the Californians put in a superior performance to most of the Boulder City High School students whom we had tested. much the volume decreases r walk with-- , during a out water and whether this loss can be prevented by drinking water." It can be prevented, reports Dr. Dill. It is largely on that account that the heart rate is lower are dnnking when you ,u ft 9n Interior Okays 6 USU Grants Special to The Tribune LOGAN Grants totalling $31)7,288 have been given to Utah State University by the U.S. Department of the Interior, Office of Water Resources.
