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 article is the 11th in 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.

Specialist law enforcement resources are under constant strain to maintain operational and organizational outcomes. The high operational tempo disturbs many functions including skill enhancement, personal development, work/life balance, and time for physical conditioning.

This article discusses the findings of a recent study on the effectiveness of a time-efficient occupationally-specific training program to improve performance in qualities related to physically demanding tactical tasks in law enforcement officers.

Abstract submissions are open yearly from November to March (exact dates change annually). See the Abstract Submission and Presentation Guidelines for more information (below). Research abstract presentations are an opportunity to present current research findings to researchers and strength and conditioning professionals at the NSCA National Conference.

This article discusses how high-intensity interval training may be an effective metabolic training method for soldiers trying to maintain physical preparedness during deployment.

This article is an overview of several studies that look into the effects of intensity and volume in the training of combat soldiers and its relation to injury.
