This excerpt from NSCA’s Guide to Sport and Exercise Nutrition discusses the research surrounding the timing of hydration and its impact on sport performance for those participating in aerobic endurance exercise.

Accentuated eccentric loading (AEL) can be combined with lower-body power-based movements to acutely enhance them; however, currently, there are limited recommendations for this training method. AEL can enhance force and power metrics during its utilization with lower-body power based exercises. When using AEL, exercises should consist of jump squats and countermovement jumps with loading methods consisting of weight releasors or dumbbell hand release. Elastic bands can be used; however, more research is needed in this area. External loads ranging from 10–30% of body mass can be used. Future research needs to investigate increased eccentric and concentric loads when using AEL with power based movements.

Lighter weights can translate to bigger muscles, Brad Schoenfeld says in this lecture from the NSCA's 2014 Personal Trainer Conference. Brad presents one of his latest studies, which looks at hypertrophy in trained subjects.

Developing safe and effective exercise training programs requires the application of abundant training variables and the implementation of appropriate progression for each variable. Importantly, the outcomes of each training program are the product of these variables and their progression, so practitioners are keen to select methodologies and overload strategies that effectively support their target training outcomes. One such training variable is mechanical loading, which describes the forces of gravity, resistance, and muscle contraction and how these forces affect musculoskeletal adaptations. Numerous research articles and texts have been published regarding mechanical loading and its effects on exercise adaptations; however, these findings can be arduous to organize, which requires additional time investment by professionals. Developing a succinct system is critical because practitioners face clients and patients with a wide range of physical skills and challenges, and having an easily referenced loading guide may assist them in designing appropriate strength and conditioning or rehabilitation programs. Thus, the purpose of this review is to define and describe the mechanical loading continuum and its individual components to better assist the practitioner in identifying appropriate exercise modes and progression strategies.

This info-graphic describes research on velocity decrements to increase propulsive and horizontal force applications to increase acceleration kinetics.

This infographic briefly reviews the differences in sprint velocity and technique, including stride length and hip, knee, and ankle flexion during a 20-meter resisted sprint.

The purpose of this article is to shed light on the most current work that has been done in examining various dietary approaches to improving markers of cardiometabolic health and performance among high-stress occupations, such as firefighters, as well as the need for additional work in this area.

The ketogenic diet, while controversial and a highly polarizing subject, has demonstrated promise as an alternative dietary strategy for weight management.
