Now when I say well controlled this means they ensured confounders that might skew the results were tightly controlled. These included making sure the participants had the same amount of calories, performed the same exercises and fell into the same age group for instance.
The researchers used 4 groups:
Group 1) Placebo and NO exercise Group
Group 2) Placebo with exercise
Group 3) testosterone (steroids) with NO exercise
Group 4) Testosterone (steroids) With exercise
The Results as stated verbatim by the researchers themselves. I took the liberty of bolding the salient points
Body Weight and Composition
Body weight did not change significantly in the men in either placebo group . The men given testosterone without exercise had a significant mean increase in total body weight, and those in the testosterone-plus-exercise group had an average increase of 6.1 kg in body weight ***8212; a greater increase than in the other three groups.
Fat-free mass did not change significantly in the group assigned to placebo but no exercise (Table 4and Fig. 1). The men treated with testosterone but no exercise had an increase of 3.2 kg in fat-free mass,and those in the placebo-plus-exercise group had an increase of 1.9 kg. The increase in the testosterone plus-exercise group was substantially greater (averaging6.1 kg). The percentage of body fat did not change significantly in any group.
Muscle Strength
Muscle strength in the bench-press and the squatting exercises did not change significantly over the10-week period in the group assigned to placebo with no exercise. The men in the testosterone-alone and placebo-plus-exercise groups had significant increases in the one-repetition maximal weights lifted in the squatting exercises, averaging 19 percent and21 percent, respectively.
Similarly,mean bench-press strength increased in these two groups by 10 percent and 11 percent, respectively.In the testosterone-plus-exercise group, the increase in muscle strength in the squatting exercise(38 percent) was greater than that in any other group, as was the increase in bench-press strength(22 percent).
In case you missed the significant aspect of this study that I highlighted by putting the text in bold. This study indicates that you DON***8217;T even have to step foot in the gym if you are juicing to induce muscle hyperthrophy. A huge advantage that can***8217;t be overstated enough this advantage goes up almost exponentially when coupled with exercise as you can see from the study.
