![]() ![]() ![]() Consumers may unknowingly take products laced with prescription drug ingredients, controlled substances, and other ingredients that cause both short- and long-term health problems. The Food and Drug Administration (FDA) warns that dangerous hidden ingredients are an increasing problem in products promoted for bodybuilding. However, most studies on the effect of these supplements are based on single ingredients rather than the impact of combined ingredients and show mixed results or have too little research to support their claim. The most common ingredients in sports-enhancing supplements include amino acids, protein, creatine, and caffeine. Some of these supplements claim to be anti-catabolic in that they increase muscle mass more quickly. Many dietary supplements claim to improve your strength or endurance, increase your exercise efficiency, help you achieve a performance goal more quickly, and increase your tolerance for more intense training. What About Performance-Enhancing Dietary Supplements? ![]() Psychiatric problems, such as depression with cessation and muscle dysmorphiaĪdditionally, users are at risk of contracting infections like viral hepatitis and human immunodeficiency virus (HIV) since these drugs are typically injected using needles. However, using these drugs can also cause irreversible damage, including: The most widely studied class of steroids and performance-enhancing drugs are anabolic steroids, which can bolster the user's confidence and strength in the short term. Steroids and performance-enhancing drugs improve appearance by building muscle mass or improving athletic performance. High-intensity interval training (HIIT) or circuit trainingĬalisthenics (exercises that use your body weight for resistance)Ī Note on Steroids and Performance-Enhancing Drugs The ACSM defines anaerobic exercise as intense physical activity of a very short duration, fueled by the energy sources within the contracting muscles. Aerobic or catabolic exercise includes:Īnabolic exercises or exercises to build muscle are commonly referred to as anaerobic exercises. The American College of Sports Medicine (ACSM) defines aerobic exercise as any activity that uses large muscle groups, can be maintained continuously, and is rhythmic. However, most frequently, catabolic exercise is called aerobic exercise. The body constantly undergoes catabolic and anabolic processes, which release and utilize energy.Īny prolonged exercise is catabolic. The energy released by catabolic processes is utilized for anabolic processes. Proteins become the building blocks for repairing or building muscle or other structures in the body.įor example, when you have an injury such as a cut, your body has to repair the wound through anabolic processes, which is why more energy is needed during illness or injury. ![]() For example, amino or fatty acids may be combined to build proteins or lipids through anabolic pathways. During fasting, when blood glucose levels drop, stored glycogen in the liver is broken down to release energy.Īnabolism uses energy to create larger, more complex molecules. In digestion, complex molecules like carbohydrates and proteins are broken down into individual molecules of glucose or amino acids that can be absorbed and transported in the body.Ĭatabolism also takes place within the body, such as in glycogenolysis. Digestion is an example of a catabolic process. Related: Best At-Home Metabolism Tests Both Processes Affect Energy SupplyĬatabolism breaks down larger, complex molecules into simpler ones, releasing energy. Hormones involved with controlling catabolism and anabolism include: Hormones, the chemical messengers in the body, are responsible for catabolic and anabolic reactions. Both words begin with the letter "A" and refer to a building up of something-in the case of anabolism, it's a building up of complex molecules. To remember what anabolism does, you can think of the word adding. Both words begin with the letter “C” and refer to the breaking down of something-in the case of catabolism, it's a breaking down of complex molecules. To remember what catabolism does, you can think of the word catastrophe. Catabolism is the process of breaking down complex macromolecules into simple molecules, such as carbon dioxide, water, and ammonia.Īnabolism is the process of building up complex macromolecules, such as nucleic acids, proteins, polysaccharides, and lipids.Ĭatabolism releases energy when molecules are broken down, while anabolism requires energy to make more complex molecules. ![]()
