Abstract

Most individuals at risk for developing cardiovascular disease (CVD) can reduce risk factors through diet and exercise before resorting to drug treatment. The effect of a combination of resistance training with vegetable-based (soy) versus animal-based (whey) protein supplementation on CVD risk reduction has received little study. The study's purpose was to examine the effects of 12 weeks of resistance exercise training with soy versus whey protein supplementation on strength gains, body composition and serum lipid changes in overweight, hyperlipidemic men.

The Berrones Analysis:

Although both types of protein, whey and soy, did not significantly affect strength or size gains, the importance of the study should not be negated. That is, resistance training is a beneficial mode of exercise that alters body composition, independent of protein supplementation. However, many studies have shown the enhanced effects of protein supplementation, namely the mixture of essential amino acids and simple sugars, on various parameters of fitness including size and strength. Thus, if one is overweight, high-lipidemic, and male, then step right up to the squat rack without your 5 lb bucket of whey, because sooner than later the cheeseburger in your arteries will plug up fifty years of healthy living.
