The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.

The purpose of this article is to examine components that affect speed to determine the degree that speed is governed by skill versus genetic factors.

The “five Ss” of trainability and performance are critical periods of development that all youth strength and conditioning coaches should consider when creating a training program. Coaches should take advantage of each window to maximize a youth athlete’s potential and help ensure a long athletic career.

Learn how to use sprinting as a means of screening athletes for power, strength, range of motion, and coordination. In this session from the NSCA’s 2018 National Conference, Derek Hansen also identifies appropriate sprinting and running mechanics for optimizing performance and minimizing injury, and outlines a process for using sprinting as a return-to-play modality for soft-tissue and joint injuries.

This article details the rationale for making the eight main movements the foundation of tactical strength and conditioning.

High-intensity strength training paired with explosive, high-velocity movements is suggested to enhance endurance performance. It is recommended that a practical approach be taken when implementing this model of strength training, which would involve a thorough preparatory period.

Dr. Tim Suchomel, Assistant Professor at Carroll University and Wisconsin State Director for the NSCA, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the emerging role of sport science in strength and conditioning. Topics under discussion include Suchomel’s growing involvement with the NSCA, as well as weightlifting derivatives and their benefits for more individualized performance adaptations.

This article provides some practical applications to minimize the negative effects associated with a long intensive ice hockey season on ice hockey athletes.

Approximately 2 million youth from 6 - 12 years of age participate in football every year. This article discusses the importance of long-term athletic development (LTAD) for youth football athletes and the significance of a player development pathway for long-term success and longevity in the sport.
