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.

In this session from the 2019 Tactical Annual Training, Stefan Pasiakos identifies mechanisms by which military operations degrade muscle mass and performance, defines warfighter nutrition requirements, and discusses ethical and efficacious androgen therapies to enhance warfighter lethality.

This article provides a discussion around the evidence on creatine timing and supplementation.

This article summarizes the relevant literature regarding post-workout nutrient timing and its importance to training adaptations, specifically increasing skeletal muscle hypertrophy and replenishing skeletal muscle glycogen stores.

This article addresses low back pain in first responders by examining three relevant studies.

Bone tissue is “alive” and is a dynamic tissue that can respond to resistance training. In addition to the obvious effects of resistance training on muscle mass and strength, resistance training may lead to decreased risk for osteoporosis, fractures, and falls in later life.

All fitness components depend on body composition to some extent, and the demands of many sports require that athletes maintain standard levels of body composition.

The purpose of this article is to discuss creatine supplementation for athletes by addressing supplementation for athletic performance, recovery, cognition, brain function, safety, contraindications, and other special considerations.

Field tests have become popular in applied exercise science and sport performance enhancement programs because of their simplicity and ability to generalize results. However, numerous confounding factors may influence the validity of test data from such evaluations.
