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.
The strength and conditioning profession involves combined competencies for the application of sport/exercise science, administration, management, teaching, and coaching. Its professionals must also comply with various laws and regulations while responding to instances of potential injury, and related claims and suits. This creates remarkable challenges, and requires substantial experience, expertise, and other resources to effectively address them, especially in multi-sport (e.g., collegiate and scholastic) settings.
Deloading is a period of reduced training stress where training demand is intentionally reduced to mitigate physiological and psychological fatigue and promote recovery. A deload is commonly implemented to enhance readiness for subsequent training and occurs between or during training phases. During a deload, training is typically modified by reducing the intensity of effort, training volume, duration, or frequency. Adjustments in exercise selection are based on recovery goals and the specific demands of the athlete’s training. Deloads are commonly preplanned and implemented into the training program every 4–8 weeks based on the structure of the training cycle and recovery needs. Alternatively, deloads are sometimes applied reactively using an autoregulatory approach to accommodate unexpected fatigue or performance decrements. While deloading shares conceptual similarities with tapering and training cessation, it should be differentiated based on its objective, structure, and positionality with the overall training program. The purpose of this article is to describe the current research landscape, propose areas for future research, and to provide broad practical recommendations for implementing deloading within the strength and physique sports training program.
This article provides the first academic history of the barbell back squat and its evolution from a bodyweight exercise in the 19th century to a loaded exercise used for a variety of purposes in the present age. In doing so, the article highlights three key drivers in the evolution of the back squat—changes in equipment, the diversification of strength sports, and scientific communication concerning the safety and efficacy of the movement. The goal of this article was not to provide a dry and irrelevant history but rather to stress the complexity of the squat’s prominence within fitness programs and the need to hold a nuanced view toward the “optimal” way to approach this movement. It examines how the movement evolved from being primarily done on the tips of one’s toes, to a loaded movement on tippy toes, to a flat-footed movement. By contextualizing the back squat’s history, this article challenges rigid notions of “correct” squatting technique and encourages a more nuanced understanding of exercise selection in strength and conditioning practice. It concludes by highlighting the importance of critically examining the social construction of knowledge in fitness and sport, and the value of historical perspective in informing contemporary training practices

The benefits of resistance training are almost overwhelming, however, too few older adults participate in resistance training, largely because of fear, confusion, and lack of consensus to guide implementation. It is the hope that this position statement may have a positive impact addressing these issues and on empowering healthier aging.
