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 introduces a periodization model designed for beginner to elite perinatal athletes, emphasizing trimester-phased training aligning with gestation, delivery, and postpartum needs. Amid progressing global recommendations on perinatal exercise and increasing female participation in high-intensity and strength training, the primary aim is to propose an evidence-based, structured approach to training that consolidates these trends. The physical and psychological demands of labor mirrors that of an athletic endeavor. As such, this article explores emerging evidence supporting maternal and fetal safety and benefit of high-intensity training, allowing pregnant individuals to prepare in accordance with the task ahead. Training phases parallel to preseason, in-season, peaking, and recovery shift in focus based on the physiological need and biomechanical necessity within the pregnancy timeline. This translation of science to practice underscores the potential for tailored training programs to positively impact maternal, fetal, and neonatal health, urging further research and unified guidelines in this evolving field.

The goal of this brief review is to describe what classifies as high-intensity interval training (HIIT) and summarize the potential benefits for various populations: athletic, general, and clinical.
