This excerpt provides a brief snapshot of the use of carbohydrates in resistance training exercise sessions.

Dietary fat has both long-term and short-term effects on an athlete and athletic performance. “Fat loading” as a strategy to improve athletic performance remains unproven.

This Kinetic Select from NSCA’s Essentials of Personal Training, Second Edition gives a brief overview of respiratory adaptations, and how aerobic interventions of duration and intensity can be used for specific adaptations for endurance 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 explores the possible advantages of staying active during pregnancy and how it can positively impact health and well-being.

A review of the literature concludes that a strength training program including low-intensity to high-intensity resistance exercises and plyometric exercises performed 2 – 3 times per week for 8 – 12 weeks is an appropriate strategy to improve running economy in highly trained middle- and long-distance runners.

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.

Knowing the risks of cold weather training is only half the battle. It is important to be familiar with a proper risk management strategy to help guide decision-making that can enhance safety and exercise performance.

This article discusses how first responder organizations can optimize their training programs through scientific techniques, including the measurement of training load.

Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.
