Abstract
In general, nutritional sports ergogenics are designed to enhance energy production and/or improve body composition, promoting muscle growth and decreasing body fat. Many nutritional supplements and pharmacological substances have been used during resistance training without knowledge of the effects on human metabolism caused by their chronic administration. Before the utilization or prescription of any ergogenic aid, it is important to consider some questions about that substance: Is it effective? Is it safe? Is it legal and ethical? In this chapter we discuss the most widely utilized drugs and supplements among individuals engaged in resistance training—testosterone, creatine, beta-hydroxy beta-methylbutyrate (HMB) and caffeine—focusing on their effects on strength and body composition, the safety of their utilization, and their mechanisms of action
