Altering set configurations during a resistance training program can provide a novel training variation that can be used to modify the external and internal training loads that induce specific training outcomes. To design training programs that better target the defined goal(s) of a specific training phase, strength and conditioning professionals need to better understand how different set configurations affect the training adaptations that result from resistance training. Traditional and cluster set structures are commonly implemented by strength and conditioning professionals as part of an athlete’s resistance training program. The purpose of this review is to offer examples of the practical implementation of traditional and cluster sets that can be integrated into a periodized resistance training program.

Anemia is a condition characterized by too few red blood cells, leading to diminished oxygen delivery, which can significantly impact exercise participation and athletic performance. The etiology of anemia is multifactorial. Some forms of anemia develop as a result of deficiencies in specific vitamins and minerals and may be modifiable, whereas other types are inherited disorders. Although nonmodifiable, the latter may be managed with the assistance of trained medical professionals. This article will provide an overview of the pathophysiology associated with common forms of anemia and provide an introduction to diagnostic testing procedures and treatment options. Additionally, the signs and symptoms will be discussed to help strength and conditioning professionals recognize this potentially impactful condition. This article concludes with a discussion of the influence iron deficiency has on sports participation.
