Protein is used to repair muscle tissues, produce hormones and transport ingested nutrients in the body. Muscles are made of approximately 70 percent water and 20 percent protein. Building muscle mass requires extra water and more energy in the form of carbohydrates, as well as more protein.
Bodybuilders take protein supplements because they use more of it in training and need the extra protein for recovery and growth. Fitness experts recommend that athletes or people who work out take about 1.5 to 2.0g protein per kilogram of body weight.
Objectives
Most people who take protein shakes practice weight training. However, all fitness enthusiasts have different objectives in taking them. They also have different body types, and their experience varies widely. Everyone's goal is to gain lean muscle, but that accomplishment is easier for some than others.
The novice weightlifter can often make significant gains right away. Her muscles respond to the new demands placed upon them and get bigger and stronger. Protein shakes can enhance this process, but it also takes extra calories to gain muscle. Protein shakes provide the building blocks for repairing the muscle fibers that get torn down during exercise. But to get the full benefits, the weightlifter must eat more calories high in proteins and carbohydrates. Carbohydrates provide the extra energy needed for muscle growth.
People who have been training for a while usually have to work harder at making gains. They often experiment with several proteins and at times use the ones that contain high calorie levels.
