How does protein help in sports?

Answer 1

Proteins help the entire body A LOT, the muscular system itself is virtually made up of entire proteins, contraction basically depends on the movement of certain proteins called myosin and actin and other kind of filaments. In rough terms, muscles are proteins.

Each actin filament slides along adjacent myosin filaments with the help of other proteinsand ions present in the cell. Tropomyosin and troponin are two proteins attached to the actin filaments that enable the globular heads on myosin to instantaneously attach to the myosin strands. The attachment and rapid release of this bond induces the sliding motion of these filaments that results in muscle contraction. In addition, calcium ions and ATP (adenosine triphosphate, the source of cellular energy) are required by the muscle cell to process this reaction. Numerous mitochondria (organelles in a cell that produce enzymes necessary for energy metabolism) are present in muscle fibers to supply the extensive ATP required by the cell.

Answer 2

Athletes need protein primarily to repair and rebuild muscle that is broken down during exercise and to help optimizes carbohydrate storage in the form of glycogen. Protein isn't an ideal source of fuel for exercise, but can be used when the diet lacks adequate carbohydrate. This is detrimental, though, because if used for fuel, there isn't enough available to repair and rebuild body tissues, including muscle.

Proteins are often called the building blocks of the body. Protein consists of combinations of structures called amino acids that combine in various ways to make muscles, bone, tendons, skin, hair, and other tissues. They serve other functions as well including nutrient transportation and enzyme production. In fact, over 10,000 different proteins are in the body.

Recommended Daly Protein Intake

• The average adult needs 0.8 grams per kilogram (2.2lbs) of body weight per day.
• Strength training athletes need about 1.4 to 1.8 grams per kilogram (2.2lbs) of body weight per day
• Endurance athletes need about 1.2 to 1.4 grams per kilogram (2.2lbs) of body weight per day

Strength athletes believe more protein is important to build muscle. It turns out that strength athletes actually require high carbohydrate intake and adequate glycogen stores to fuel their workouts. It is the strength training workout that leads to increased muscle mass and strength. This is because all high intensity, powerful muscle contractions (such as weight lifting) are fueled with carbohydrate. Neither fat nor protein can be oxidized rapidly enough to meet the demands of high-intensity exercise. Adequate dietary carbohydrate must be consumed daily to restore glycogen levels.

Answer 3

Of course they do. And if they don't HELP them, they are not bad for them.

Answer 4

So they may become slim and fast and if they dont have proteins they will get slow and sick and cant be athletic and play sports.

Answer 5

to help build muscle mass.
