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.

An anterior cruciate ligament (ACL) tear is one of the most frequent injuries experienced by athletes of all levels. Because so many variables are at play, there is a great deal of controversy about how and why this occurs. In addition, there are various suggested appropriate steps to take to return to sport in the fastest and safest possible way. However, a major issue in injury recovery and return to sport practices is the lack of a gold-standard method or a consistent course of action that an athlete should undertake after suffering an ACL injury. Therefore, the purpose of this paper is to review the literature to determine evidence-based methods for return to sport after ACL reconstruction and provide practical recommendations to guide the process.

An individual’s training status is a key factor used to determine the volume, the intensity, and the selection of exercises for resistance training prescription. Interestingly, there are no objective parameters to assess training status, so there is ambiguity in determining the appropriate volume and other resistance training variables in this regard. Thus, the objective of this study was to propose a strategy for classification and determination of resistance training status. The following five parameters were identified and used: (a) current uninterrupted training time, (b) time of detraining, (c) previous training experience, (d) exercise technique, and (e) strength level. Moreover, 4 classification levels are proposed: beginner, intermediate, advanced, and highly advanced, which are determined by the mean score of the parameters used. The proposed model represents an important advancement in training status classification and can be used as a valid tool for training prescription and for researchers to better characterize a sample and reproduce results under the same conditions in future studies.

In this session from the 2020 NSCA Coaches Conference, Matt Nein, Coordinator of Sports Performance at Salisbury University, discusses his fluid periodization model for coaches to use to easily adapt to the changing situations on a week-to-week (or even day-to-day) basis, and still optimize training for the athletes.

Firefighting is a profession that has the potential to be extremely demanding, both physically and mentally. More specifically, these tactical personnel must be physically fit to perform their occupational requirements, all while they are exposed to daily stressors. This is likely to include everything from physical strain and shift work to interrupted sleep and witnessing potentially traumatizing events. Failure to prepare and mitigate these occupational demands can have long-lasting implications to overall performance as well as health and wellness. Unfortunately, many of these elements often go unaddressed. As such, considerations for collaborative and overarching cross-disciplinary allied health teams should be made. Human performance optimization (HPO) is a model that has been successfully adopted by the U.S. military to enhance the overarching health, wellness, and performance of soldiers. This article proposes the utilization of a similar HPO model by providing a rationale for how it can be used to reduce premature morbidity and mortality, as well as increasing overall readiness and resilience within the firefighting profession.

The demanding and hazardous nature of firefighting necessitates a fitness testing framework that directly addresses the unique physiological challenges of the profession. This paper sought to identify gaps in the current fitness testing and training environment that are focused on cardiovascular, respiratory, muscular endurance, and muscular strength components of fitness and to advocate for a targeted, occupation specific fitness testing approach that aligns with the physiological challenges firefighters face. Ultimately, implementation of these plans should reduce the risk of injury and death and improve operational efficiency.
