Todd Miller, PhD, CSCS, TSAC-F, FNSCA and professor at George Washington University discusses body composition measures and techniques and understanding body composition ranges and their effect on health and performance in this session from the NSCA's 2023 Personal Trainer's Conference.

The importance of physical fitness is never greater than when lives are at stake. Specifically, professionals in law enforcement, fire/rescue, and the military need fitness and tactical athleticism to efficiently respond to calls and complete missions regardless of the obstacles, mixed terrain, interference, and dangerous environmental conditions involved

Resistance training or strength training has become one of the most popular forms of exercise, because it is the only method capable of improving physical fitness and increasing muscle mass simultaneously. Among the variables of training, the relationship between intensity and volume has been extensively addressed to enhance exercise induced muscular hypertrophy. For many, mechanical stress is seen as a factor of greater relevance and, because high loads promote greater mechanical tension and high intensities are traditionally used to increase muscle mass. However, evidence has shown greater safety and similar results through training based on lower intensities and increased training volume. Thus, this narrative review aimed to search the current literature for evidence on using different training loads to promote muscle hypertrophy. An extensive nonsystematic literature review was conducted in the PubMed, Google Scholar and Scielo databases. It was possible to conclude that the use of high and low intensity promotes similar results in muscle hypertrophy in all groups, leading to the belief that there is greater safety and adherence to the use of lower intensities compared with close effort to concentric failure.

This continuing education opportunity explores a variety of topics as they pertain to training the youth population. To earn your CEUs, it will be necessary to review several articles and pass a 50-question quiz. Please note: this quiz awards 1.0 CEU (10 contact hours). Articles 1) Effects of Balance Training on Physical Fitness in Youth and Young Athletes: A Narrative Review 2) Seven Pillars of Prevention: Effective Strategies for Strength and Conditioning Coaches to Reduce Injury Risk and Improve Performance in Young Athletes 3) Navigating the Complex Pathway of Youth Athletic Development: Challenges and Solutions to Managing the Training Load of Youth Team Sport Athletes 4) Energy and Macronutrient Considerations for Young Athletes 5) Assessing Athletic Motor Skill Competencies in Youths: A Narrative Review of Movement Competency Screens

The TSAC Report is the NSCA’s quarterly, online-only publication designed for the training of tactical professionals, operators, and facilitators. You must be a member of the NSCA to access the TSAC Report.

Altering set configurations during a resistance training program can provide a novel training variation that can be used to modify the external and internal training loads that induce specific training outcomes. To design training programs that better target the defined goal(s) of a specific training phase, strength and conditioning professionals need to better understand how different set configurations affect the training adaptations that result from resistance training. Traditional and cluster set structures are commonly implemented by strength and conditioning professionals as part of an athlete’s resistance training program. The purpose of this review is to offer examples of the practical implementation of traditional and cluster sets that can be integrated into a periodized resistance training program.

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.

Early sport specialization involves physically immature children participating in intensive year-round training and/or competition for a single sport. The lack of sport exposure and diversification during the developmental years may underlie the increased risk of overuse injuries, blunting of motor skill development, psychosocial issues, overtraining syndrome, burnout, and potential dropout from sport. With increasing number of youth choosing, or being encouraged, to specialize at an early age, we aim to provide evidence based recommendations for the integration of strength and conditioning into the development programs of young athletes who participate in sports with a culture of early specialization. In addition to the principles of programming, strategies are provided relative to monitoring of growth, maturation, and training load to illustrate the potential complexities of attempting to optimize long-term athletic development in early specializing athletes.
