Effects of taking bodybuilding supplements Resistance training is hard work and requires a lot of energy and juice from the human body, which cannot be reconstituted as quickly as desired; However, there is a solution to pain and slow muscle gain: bodybuilding/performance supplements. Athletes around the world take performance supplements every day, usually in some form of protein supplement, whether whey protein or protein derived from vegetables or soy. Whether such supplements that are not regulated by the FDA have more positive than negative effects remains a considerable debate; however, the effects cannot be denied after ingestion. The positive effects of using supplements are far more beneficial than not taking them at all due to the increased stimulation and maintenance of muscle growth when taking whey protein and other supplements. (Tobias, 2013)Physical performance depends on several variables such as strength, which mainly means muscle strength and the only way to increase muscle strength is through muscle breakdown and synthesis of destroyed muscles. Protein is the number one factor that plays a role in rebuilding muscle that is being broken down. When protein is consumed in any form, such as supplements or natural proteins found in foods, it is used to rebuild and help structure muscles and all other parts of the body (Wolfe, 2000).
