This PTQ article reviews scientific literature on concurrent training and examines whether combining aerobic and resistance exercise has meaningful impacts on performance. Visit the NSCA online to read more about personal training.

The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.

This NSCA Coach article discusses training modalities in bench press training and incorporating accessories to improve rate of force development (RFD) among athletes. Visit NSCA online to read more on strength training and exercise science.

This excerpt from the Essentials of Strength Training and Conditioning outlines what training typically looks like in the preparatory period, or off-season.

This article aims to explain why integrating multiple tests such as Anaerobic Speed Reserve (ASR), Intermittent Fitness Test (IFT), and Maximum Aerobic Speed (MAS) can provide a comprehensive evaluation of soccer players’ fitness levels and help to design effective training programs tailored to their individual needs.

Considering the great popularity of eccentric-based training, the purpose of this review is to first provide the scientific rationale for its use; second, summarize the eccentric-based training modalities that can be used; and finally, offer practical recommendations on how to implement eccentricbased modalities to enhance sports performance. The molecular and neural mechanisms underlying eccentric actions are partially distinct from those of concentric and isometric actions. During eccentric actions, theories suggest a strain-induced modulation of actin-myosin interactions at the crossbridge level, activation of structural protein titin, and winding of titin on actin. Eccentric acute physiological responses differ from concentric exercise responses, including variations in neuromuscular, metabolic, hormonal, and anabolic signaling. Eccentric training elicits greater improvements in muscle strength, power, and stretch-shortening cycle function compared with concentric-only or traditional resistance training. Therefore, eccentric-based training can lead to unique neuromuscular (e.g., improved coordination of motor units) and morphological (e.g., increased muscle fascicle length and enhanced distal cross-sectional area) adaptations that could play a key role in sport performance. Practitioners may implement eccentric exercises with external loads, fully eccentric-based exercises (e.g., Nordic hamstring curl), accentuated eccentric loading, flywheel resistance exercise, and plyometrics to develop specific physical adaptations in line with their goals. Eccentric work (e.g., for hamstrings) can be obtained during other exercises such as downhill running tasks, decelerations, and sprinting activities. Practitioners need to be aware that no single “silver bullet” training modality exists; consequently, practitioners should use a combination of eccentric-based training approaches with their athletes to obtain the desired adaptations.

Learn the basics of conducting a needs analysis for tactical athletes based on the athlete’s goals and desired outcomes, assessments, limitations on workout frequency and duration, equipment availability, health and injury status, and occupational physiological demands.

This article discusses the effects of instability on force and velocity throughout the body.

In the second of this two part series, this article will discuss program design with an emphasis on integrating lower limb plyometric training into soccer training to enhance power actions, as well as, consider high school athletes’ biological characteristics and long-term athletic development (LTAD).
