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.

Eccentric resistance training has been shown to elicit beneficial effects on performance and injury prevention in sports because of its specific muscular and neural adaptations. Within the different methods used to generate eccentric overload, flywheel eccentric training has gained interest in recent years because of its advantages over other methods such as its portability, the ample exercise variety it allows and its accommodated resistance. Only a limited number of studies that use flywheel devices provide enough evidence to support the presence of eccentric overload. There is limited guidance on the practical implementation of flywheel eccentric training in the current literature. In this article, we provide literature to support the use of flywheel eccentric training and present practical guidelines to develop exercises that allow eccentric overload.

The first step in preparing a comprehensive periodized strength and conditioning program is the needs analysis —that is a formal process for determining the general and specific needs of the athlete based on their sport or task. It involves many more pieces than most consider and is not simply about goal setting. Depth and specificity of event requirements and details are important because there will be variability in needs and program design due to the task and level of prior experience and participation. The specifics of the task and the particulars of the individual athlete may lead to the need for significant study and reading of evidence-based research. The benefit of a well-developed needs analysis is that it can lead to better program planning with greater opportunity for success.

Dietary supplement use is quite prevalent among bodybuilders to enhance their physiques for competition. Many of the dietary supplements used by these athletes are neither safe nor effective. Several reviews have been published detailing the efficacy of dietary supplements for athletes; however, none have been written specifically for bodybuilders and physique athletes. Therefore, the aim of this article is to provide an evidence-based review of the top 5 dietary supplements for bodybuilding competitors: creatine, caffeine, protein powders, free-form essential amino acids, and beta-alanine. This review will provide bodybuilders, coaches, and practitioners with information on each supplement’s mechanism of action, seasonal benefits, protocol for use, and special considerations to optimize supplement strategies for performance, physique, and overall competitive success.

Early sport specialization involves physically immature children participating in intensive year-round training and/or competition for a single sport. The lack of sport exposure and diversification during the developmental years may underlie the increased risk of overuse injuries, blunting of motor skill development, psychosocial issues, overtraining syndrome, burnout, and potential dropout from sport. With increasing number of youth choosing, or being encouraged, to specialize at an early age, we aim to provide evidence based recommendations for the integration of strength and conditioning into the development programs of young athletes who participate in sports with a culture of early specialization. In addition to the principles of programming, strategies are provided relative to monitoring of growth, maturation, and training load to illustrate the potential complexities of attempting to optimize long-term athletic development in early specializing athletes.

Typically, a coach may follow a process in which they first identify the key performance indicators of their sport, determine the physical attributes that map back to them, and then distribute the development of those capacities over the allocated timeframe. Furthermore, effective training plans are based on a theoretical or biological basis for how we move and adapt to exercise stimuli, coupled with an understanding of how these are best sequenced, such that one stimulus and subsequent adaptation can potentiate the next. Thus, reverse or backward engineering, when appropriately converged with the plans of those devised around nutrition, conditioning, technical, and tactical training, for example, likely gives athletes the best chance of attaining their performance goals. The aim of this article is to describe the application of reverse engineering, exampling it within the context of developing an athlete who can demonstrate a high level of agility.

Although fatigue is commonly experienced in many highly demanding occupations (e.g., military, first responders, etc.), it is poorly defined. Fatigue can strongly affect occupational performance by negatively influencing the ability to interact with the world by altering the capacity to think, move, feel, see, and speak. The first step in fatigue risk management strategies is to establish a context. The context of this narrative review is to specifically describe and discuss the 6 overarching types of occupational fatigue: cognitive, physical, burnout, emotional, visual, and vocal fatigue, and how each affects varying occupations. Furthermore, fatigue type can be influenced by several intrinsic factors, such as sleep deprivation, circadian alignment, ultradian process, sleep homeostasis, and health factors. Similarly, extrinsic factors influence fatigue, such as workload, shift work, and environmental issues. Understanding the types and contributors to occupational fatigue may help clarify the context of occupational fatigue and serve to guide future occupational fatigue management.

Nutrition and dietary intake are key factors for exercise and sport performance. While a substantial body of research highlights the impact of nutrition on exercise, many dietary and nutrient recommendations are based on research studies only conducted in men. However, the distinct physiological, neurological, and hormonal changes across a woman’s life cycle significantly affect nutritional needs. This narrative review explores key recommendations for calories, carbohydrates, fats, proteins, and select supplements, highlighting the absence of sex-specific guidelines in current dietary frameworks for strength and conditioning female athletes. The review synthesizes current literature to provide practical guidance for coaches, sport dietitians, and health practitioners to optimize both performance and health outcomes for female athletes.

Falls resulting from trips are a leading cause of injury and can sometimes result in death, especially in the older population. Numerous researchers have studied the biomechanical mechanisms that differentiate fallers from nonfallers and determined whether training can beneficially impact those outcomes. Exercise and task-specific interventions have demonstrated fewer falls after trips but can be costly and often require specialized equipment, making their applicability less practical. Qualified health and fitness practitioners can develop evidence-informed, exercise-based programs focusing on 3 components (balance training, task-specific training, and resistance exercise). Such programs may help to reduce fall risk in older adults based on previously documented studies identifying the biomechanical demands of a successful fall arrest after a trip perturbation. These multicomponent programs should include a safe task-specific training element that does not require specialized equipment.
