The Weight Restriction For Muscle Mass During Resistance Training

Introduction Over the last few years, there has been an increasing weight lifting culture. Adepts of the weight lifting community have developed all sorts of theories and training regimens in order to optimise the gains in muscle mass during resistance training. Unfortunately, many methods developed by these adepts have not yet been proved to be efficient by any scientific studies. Luckily, some researchers have studied the responses of muscle protein metabolism to nutrition and exercise and have enlightened us with knowledge regarding the function and importance of certain nutrients in protein synthesis (K. Tipton & Wolfe, 2001)

When performing resistance training over a period of time, muscular mass can increase (hypertrophy) in response to the specific stimulus induced on the muscle fibers during the exercise. In order for the skeletal muscle to grow, net protein synthesis must occur (protein synthesis must exceed protein breakdown). Net protein synthesis is non-achievable if resistance training is performed alone without the intake of certain dietary nutrients (K. Tipton & Wolfe, 2001). Recent evidence has shown that an increase in circulating amino acids induced by the consumption of certain nutrients following exercise can increase the net protein balance due to stimulation of muscle protein synthesis (Tang et al., 2007). Amino acids are the basic unit of protein structure and peptide bonds link amino acids in chains that take on diverse forms and chemical
