Casein Protein for Sports & Fitness
Why Do Athletes Use It?*
Some athletes say that using casein protein improves weight training results by providing a steady supply of amino acids over several hours.
What Do the Advocates Say?*
Protein is necessary for building and repairing muscle, and this is especially important for bodybuilders. All types of protein, including casein, provide the body with amino acids. However, compared with other protein supplements, casein is slowly digested, resulting in a slower yet more prolonged rise in blood levels of amino acids, so some fitness professionals believe it may help support muscle growth and strength gains in weight-training programs.
How Much Is Usually Taken by Athletes?
In a controlled trial,1 1.5 grams per day of predigested casein protein per 2.2 lbs body weight helped overweight men gain strength and lean body mass, and lose body fat during a weight loss diet and weight training program. These changes were greater than for men using a similar amount of whey protein along with the same diet and exercise plan.
