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.

This infographic outlines a three-step process to determine the efficacy of selected jump metrics and the ability to use them in practice.

In this session from the NSCA’s 2018 TSAC Conference, Josh Hagen explains the importance of having an understanding metrics and how to implement monitoring for tactical athletes to influence training for optimal performance.

This article presents a contemporary, evidence-based, and practical framework that reduces the many strength and speed-strength metrics into five distinct qualities.

What training approaches are efficient and effective at developing functionality and resiliency at the core? The answer lies within an intelligent, systemic, multi-method approach to training the core, including an eclectic set of training tools to individualize specific needs of athletes.

This course is an introduction to force plates and performance testing. This course covers the basics of setup and calibration of force plates, and then walks through several fundamental performance tests including squat jumps, countermovement jumps, drop jumps and loaded jumps. Two versions of the isometric mid-thigh pull as well as an isometric squat are also covered in the course. Real-time data collection from the software is also shown as the athletes are performing the tests. A module on data analysis rounds out the course, which includes five metrics collected from the force plate, as well as calculations from this data, including relative strength index - modified, and dynamic strength index.

This excerpt from NSCA’s Essentials of Sport Science highlights the importance of quantifying training load for both programming and monitoring an athlete’s progression or regression over time.

With the pervasiveness of chronic disease, personal trainers need to be vigilant in their efforts to gain new clients and retain current clients, while maintaining the scope of practice boundaries. By reviewing the needs and expectations of customers and stakeholders, a process for improving service can be developed.

One of the most important elements of running a fitness studio, no matter the discipline or the size, is understanding the competitive landscape. Gaining a key perspective on what is happening not only in the market, but also in the fitness industry as a whole, can provide owners and managers with the insight necessary to uncover the data and trends for their business to thrive.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.
