This infographic summarizes how varying sled-loads increase different characteristics of sprint performance in male high school athletes.

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.

Certified Strength and Conditioning Specialist Exam Description. The Certified Strength and Conditioning Specialist® (CSCS®) exam is comprised of two sections that test the candidate's knowledge in the Scientific Foundations and Practical/Applied areas.

Interest is growing in warm-up procedures that involve dynamic activities and sport-specific movements that maximize active ranges of motion at different movement-specific speeds while preparing the body for the demands of sport training and competition.

This excerpt from Developing Agility and Quickness provides a needs analysis for field hockey and possible program design options for optimal performance outcomes.

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.

Megan Young, Performance Coach at Auburn University, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about the data revolution and combining science and coaching to validate the “coaching eye.” They also discuss the importance of your professional network, building a strong performance team, and the need to unify the profession.

Studies support the use of kettlebells for improving power, although evidence for using them to improve strength and aerobic fitness is still equivocal. Studies investigating the biomechanical properties of kettlebell training have been fruitful, and it may be useful for developing sprint running performance and for injury prevention.

This article uses relevant research and literature to provide suggestions for optimal recovery in tactical operators.
