MusclePharm BCAA (Amino1) no more effective than Carbohydrate (*study)

A recently published study examining MusclePharm’s Amino1 (BCAA with a couple grams of carb) product versus straight carbohydrates (Powerade) has found that it offers no advantage in reducing markers of muscle damage/soreness, or improving strength.

Here’s how the study went down:

Thirty (30) healthy resistance-trained males (n = 30) donated a baseline blood draw and were measured for both peak quadriceps isometric and isokinetic torque (via leg extensions) as well as electromyography (EMG) activity at 60°/s and 120°/s, and tested for their one repetition maximum (1RM) barbell back squat.

The participants then went home (or wherever, I’m not their mother), and returned a week later to perform ten sets of five reps (5 x 10) at 80 % of their 1RM barbell back squat for 3 consecutive days. Blood was drawn 24 hours after the first and second lifting bouts.

Immediately and 24 hours after the three lifting bouts, participants consumed either Amino1 (for a total of two servings of MusclePharm’s BCAA product) or Powerade (equaling 42g of carbs, basically fructose, glucose, and sucrose).

Two days (48 hours) after the third session, they returned and repeated the prior week’s testing session (blood, leg extensions, 1RM squat). They also measured

The MusclePharm BCAA supplement, at two servings per day, was shown to be no more effective than simply chugging a Powerade.

The study concluded:

“BCAA-CHO [AMINO1] supplementation did not reduce decrements in lower body strength or improve select markers of muscle damage/soreness compared to CHO supplementation over three consecutive days of intense lower-body training”

It looks like the highly-prestigious MusclePharm Sports Science Institute may have to update their description of Amino1:
