Abstract

This study was a staff experiment carried out in 1953 as a follow-up to several preliminary experiments by graduate students at the University of Illinois, School of Physical Education. The studies were carried out in the Physical Fitness Research Laboratory. The preliminary studies as well as the staff experiment of 1953 and the reversal experiment of 1954 all showed some advantage for supplementary feedings of wheat germ oil (WGO) administered during or immediately following physical conditioning periods of conditioning exercises and swimming in an indoor pool with water temperature 74°-76° F. The subjects were adult men, 26–60 years of age, mainly sedentary, volunteers from the nonphysical education staff.

The WGO capsules (20 capsules per day, 3 minims each, and each containing 175 mg. of WGO and 0.44 mg. of mixed tocopherol) were fed for eight weeks in connection with the progressive physical training experiment. Two groups of eight men each were matched in treadmill-running time, the brachial pulse wave and age. Two other inactive control groups of 5 men each were tested at the beginning (T₁) and at the end (T₂) of the eight week period. The group results show significant advantage for the experimental subjects who took WGO over those who did not in both performance (willpower dominated) tests and in naive (non-willpower) tests.

The physiological advantage is shown in terms of running endurance in “all-out” treadmill runs, T-wave of the ECG (CR_iv-vlead), lower systolic blood pressure, the Schneider Index and the Illinois total body reaction-time test in response to light, sound, and combined signals. Individual differences in response are shown and some of the factors which cause such variations are identified.
