Research Methods

The topic of this study is carbohydrateintake of pre workout.
The attributes of the subjects whoparticipated in the experiment were asfollows

In addition, the experiment is asfollows.

Carbohydrate intake of preworkout	Subjects drank one of the following drinks and thenperformed the workout. Subjects also tried each of these threepatterns. 0 grams of carbohydrates (just water) 2.4grams of carbohydrates (a placebo drink made to look like it's full ofcarbohydrates) 120 grams of carbohydrates (a drink that isactually full of carbohydrates)
The timebetween ingesting carbohydrates and workout	2hours
Workout content	Perform 4 setsof squats at 90% of 10RM. Perform 4 sets of bench presses at90% of 10RM.
What this experimentconfirmed	What effect do differences in carbohydrate intakehave on workout performance?

	After drinkingwater	After taking a placebo drink	After drinking acarbohydrate drink
Average number ofsquats	38 times	43 times	44times
Average number of bench presses	37times	38 times	39times

Comparing the placebo drinkwith the carbohydrate drink, there was no significant difference inthe number of squats and bench presses for either.
Comparingthe subjective satisfaction after drinking a placebo drink with afterdrinking a carbohydrate drink, there was no significant difference.(p=0.18)
On the other hand, the satisfaction after drinkingwater was quite low.

Thepsychological satisfaction of having taken carbohydrates affectsworkout performance more than the actual amount of carbohydrateintake.
