Steroids, dosage, and the placebo effectNutritional depletion commonly occurs in patients with COPD, causing muscle wasting and impaired physiologic function. Nandrolone decanoate or placebo P was stefoids intramuscularly women, 25 mg; men, 50 mg in a double-blind fashion on Days 1, 15, anabolic steroids the physiological effects of placebos, and Nutritional intervention consisted of a daily high caloric supplement kcal; ml. Also, all patients participated in an exercise program. In the depleted patients, both treatment regimens induced a similar significant body weight gain 2. Nutritional steeroids in combination drostanolone propionate homebrew a short course of anabolic steroids may enhance the gain in FFM and respiratory muscle function in depleted patients with COPD without causing adverse side effects.

Fifteen male varsity athletes were informed that some of them would be selected to receive an anabolic steroid Dianabol. Instead, six selected subjects were given placebo pills. Taking the placebo apparently supplied the psychological inducement to increase strength gains above and beyond reasonable progression. Greater training gains were made during the placebo period in three out of four weight lifting exercises. The gains were statitsically significant when comparing the two regression lines for the pte-placebo and placebo periods.
The work of Kochakian and Murlin 1 provides the basis for the use of anabolic steroids. The pharmacological properties of these steroids have proved of value clinically in the treatment of conditions where protein synthesis and reduced nitrogen loss is desired. The dieculty of detecting these substances in the urine or blood assures their continued use despite criticism and prohibition by official rule making bodies such as the NCAA. This study is one of three in an investigation of the short and long term effects of an anabolic steroid Dianabol upon human performance.
Johnson and O'Shea 3 found that strength, body weight, oxygen uptake and blood nitrogen retention were significantly increased when an anabolic steroid was administered to healthy subjects. This research was supported by a grant to Dr. FR awarded to the University of Massachusetts. The latter significantly increased their strength performance while the swimmers were unable to improve their competitive speed performance.
Neither group displayed any toxic side effects. These same authors have emphasized the need for a "severe" exercise regimen and a protein dietary supplement to accompany the administration of the steroid.
Fowler 5 reported no effects of steroids on strength. The length of time that the steroid was administered may have been responsible for these results. The motivational effects of the administration of anabolic steroids have not been measured.
Doubleblind studies have not been conducted with healthy subjects because the opinion was held "that doubleblind assays arc primarily necessary for the securing of subjective clinical data and serve little purpose in the collection of biochemical or physical measures" 4.
Double-blind testing was not considered compatible with small sample sizes. One must contend, however, that motivational factors could influence physical performance measures. A positive attitude towards the beneficial effects of an anabolic steroid by highly motivated, top class athletes, seems reasonable. In the present study, 15 male varsity athletes ; were used. All 15 volunteers had experienced two years of hard weight training, 5 days a week, reduced to twice a week during vacation periods.
A standard warns-up procedure was performed after which each test "consisted of a. The subjects were informed during this preliminary period that the most improved lifters would be selected and given an anabolic steroid Dianabol. Eight subjects were selected randomly from the initial 15 volunteers. The Director of the University Health Services explained the possible physiological effects of the anabolic steroids in a positive manner. Research studies reporting the strength gains associated with anabolic steroids were made available to the subjects.
After the pre-experimental period the 8 selected subjects were tested for maximal strength in the aforementioned exercises. The University Health Service ran screening tests appropriate for the other two phases of these experiments and excluded two of the subjects.
The remaining 6 subjects were given placebo pills daily provided by the University Health Service with the information they contained 10 mg of Dianabol, an oral anabolic steroid. Data were collected, as previously described, for seven weeks of the pre-placebo period PP , and for four weeks of the placebo period P. During the P period no dietary supplements were administered. As strength gains are a function of training over a period of time, neither the "t-test" nor one-way-analysis of variance for "before" and "after" conditions were deemed totally adequate analysis techniques.
The relationship between both the gains in strength and the effect of time for the PP period and the P period suggested a comparison of the regression lines for these two periods with regard to the psychological influences upon strength gains.
Figure 1 illustrates the regression lines of the strength test measurements for the PP and the P periods and Table 1 shows the analysis of these regression lines. The significant F ratios between the slopes illustrate, however, that the gains in the P period were significantly greater than those in the PP period. The test of significance of the differences obtained in the military press Table 1, B clearly shows that there was no significant increase in strength by the subjects during the course of the PP period.
However, during the P period there was a progress which was great enough to permit a significant difference between the two slopes and the P slope showed a greater increase in strength. The sitting press results Table 1, C 'illustrate significant gains during both periods but the P period gain was not sufficiently greater than the PP period to permit a significant difference in the two slopes.
This demonstrates that the strength gains as a function of time for the two periods were not significantly different.
When the total progress in all four exercises for the two periods was tested Table 1, E , the subjects had a significant improvement. When these gains were compared, a significant difference was evident in favor of the P period. These results clearly indicate that although the subjects continued to improve during the PP period, the improvement during the P period was significantly greater.
Taking the placebo apparently supplied the necessary psychological benefits to utilize strength gains above and beyond that which would be expected from a reasonable temporal progression. In order to compare the results of the present study with those of other authors 3 a one-way analysis of variance was used to find if there was statistically significant differences between the PP and P periods.
The results are presented in Table 2. With the exception of the sitting press exercise, greater gains were made during the placebo period and these gains were statistcally significant.
The absence of gains in the sitting press may have been as a result of the order of execution and the opposing effects of psychological enhancement and neuromuscular fatigue. With this demonstration of psychological enhancement of human performance, investigators must be cautious when assessing the effects of supplemental treatments on performance. The assumption that one dependent variable has been isolated may well be erroneous, and observed differences may not be solely attributable to one such variable.
