In this session from the 2018 Personal Trainers Conference, Registered and Licensed Dietician, Dawn Weatherwax, provides a detailed look into the different variables that affect nutrition outcomes, body composition, metabolic testing, and supplementation for deficiencies, recovery, and optimal performance.

In this video from the NSCA's 2014 Movement Performance Clinic, Gray Cook, OCS, CSCS, introduces the Functional Movement Screen (FMS), and discusses the importance of testing and assessing your athletes' and clients' ability to move well.

This article discusses the variability in physical testing outcomes for law enforcement recruits based on the ambient temperatures and relative humidity present on test day.

In order to ensure consistent and accurate results, coaches must take certain steps to ensure proper data collection. It is also important to establish sound protocols prior to testing.

Matt Crawley, Strength and Conditioning Coach and Internship Coordinator for the Ultimate Fighting Championship (UFC) Performance Institute, discusses performance considerations around testing and programming for UFC fighters, as well as the role of the strength and conditioning coach within the interdisciplinary team.

The body’s system can be observed by blood testing to help achieve desired results whether training for a competition, pursuing an individual goal, or improving general health.

Fitness testing uses a battery of protocols recognized by the scientific community as both reliable and valid, and it measures important fitness constructs such as aerobic endurance, muscular strength, muscular endurance, power, agility, flexibility, and balance.

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.

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.

The administration and measurement of youth power development has become more available and familiar with the advances of technology. This excerpt introduces varieties of testing and administration practices to assess power in the youth population.
