The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.

Athletes engage in training programs that develop physical and physiological attributes to improve performance over time. However, ensuring athletes are optimally prepared just before competition is also of utmost importance. Indeed, such approaches may often adopt 1 or more strategies in the days, hours, and minutes preceding competition, including exercise priming, active warmup, and/or postactivation performance enhancing (PAPE) activities. Despite a plethora of discrete research, such information seems poorly synthesized, making it difficult for coaches and athletes to implement optimal evidence based physical preparation approaches in many sporting contexts. This article aims to provide a scoping overview of evidence, facilitate discussion, and where possible, propose practical exercise based recommendations that may be useful leading up to (~48 hours–~1 minute) tasks with a short or prolonged endurance component or requiring repeated intermittent efforts (e.g., team based field sports). Well-timed and –designed activities can facilitate several aspects of physical performance, potentially improve athletes’ psychological state(s) and mental preparedness. The benefits of a warm-up are most well documented, but priming and PAPE strategies also warrant consideration. It is intended that the evidence and suggestions presented will be useful for strength and conditioning professionals preparing athletes for competition.

Firefighting is a profession that has the potential to be extremely demanding, both physically and mentally. More specifically, these tactical personnel must be physically fit to perform their occupational requirements, all while they are exposed to daily stressors. This is likely to include everything from physical strain and shift work to interrupted sleep and witnessing potentially traumatizing events. Failure to prepare and mitigate these occupational demands can have long-lasting implications to overall performance as well as health and wellness. Unfortunately, many of these elements often go unaddressed. As such, considerations for collaborative and overarching cross-disciplinary allied health teams should be made. Human performance optimization (HPO) is a model that has been successfully adopted by the U.S. military to enhance the overarching health, wellness, and performance of soldiers. This article proposes the utilization of a similar HPO model by providing a rationale for how it can be used to reduce premature morbidity and mortality, as well as increasing overall readiness and resilience within the firefighting profession.

Adequate nutrition generally promotes training adaptations and thus optimal performance. Adolescence is characterized by a pubescence growth spurt, increasing energy and nutrient needs. Most team sports literature focuses on male athletes, with little on adolescent female team sports. Adolescent female athletes are at an increased risk of inadequate energy, and micronutrient intakes because of the pursuit of high fitness levels, and society pressures. This may cause hormonal irregularities, delayed development, poor bone health, and increased risk of injury. This review synthesizes information on the nutritional needs of adolescent female team sport players for performance and health.
