Abstract

The purpose of this study was to determine whether or not Dianabol (methan- drostenolone), an anabolic steroid, was effective in increasing muscular strength and stamina. Studies done in the past have not provided accurate results, due to their research techniques. The research technique in this study is highly accurate for measuring muscle strength and stamina. Thirty white rats were used. Ten served as control animals. Ten were given a daily dose of .35 mgkgday of Dianabol for 30 days. The remaining ten received a daily dose of .35 mgkgday of methyltestosterone. Strength of contraction of the muscle and fatigue time were measured on the physiograph. Results indicatethat contraction strength and contraction time for the Dianabol animals were not significantly better than for control animals. However, the testosterone animals showed significantly stronger contractions and increased stamina than the other two groups. This study suggests that Dianabol does not increase strength nor stamina.
