This article addresses emerging research that both supports and refutes betaine’s capacity to promote muscular adaptations.

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.

Most law enforcement officers are physically taxed, mentally exhausted, and emotionally overwhelmed. As such, a complexity exists with a requirement to match the need for physical fitness in a demographic that lives their lives in a potential state of general exhaustion.

The purpose of this article was to conduct a process evaluation of a six-week recruit strength and conditioning programming for rural structural firefighter recruits.

This article provides considerations for preparing firefighters for the physical and psychological demands of their job, including pre-operational work specific training during their rest times.

Coaches can help children and adolescents develop athletic ability by including motor skills training into sports practice and training. This approach is called integrative neuromuscular training.

This article will demonstrate why personal trainers should consider the use of blood flow restriction (BFR) and BFR technology for appropriate medically-screened clients that provides an objective way to apply pressure, whether that is through manual or automated cuffs.

This article is part of 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.

Exercise is an underutilized therapy for the treatment of cognitive diseases such as Alzheimer’s disease and depression. While exercise shows more promise for the prevention, rather than the treatment, of Alzheimer’s disease, exercise therapy compares favorably to the most common treatments of depression (psychotherapy and antidepressants).

This article discusses the importance of upper body power training for protective security personnel and its potential for an occupational performance marker.
