Proteins are vital macromolecules and the primary building blocks of muscle tissue, playing a crucial role in muscle synthesis and repair. During resistance training and other forms of exercise, you induce micro-tears in your muscle fibers, necessitating repair for growth. Proteins facilitate this repair and growth process, leading to muscle hypertrophy. Without adequate protein, the repair process stalls, potentially leading to muscle deterioration, reduced strength, and an increased risk of injury over time.
Moreover, proteins supply essential amino acids that are not produced by the body. These amino acids are critical for synthesizing new muscle tissue and maintaining the integrity of existing muscles. A lack of these building blocks can hinder your progress and make it challenging to achieve desired fitness outcomes.
