In this session from 2019 Coaches Conference, Paul Laursen, co-author of the book “Science and Application of High-Intensity Interval Training: Solutions to the Programming Puzzle,” explains the physiological targets of high-intensity interval training and how to design and manipulate variables for a variety of applications.

This article will present a sample program that was implemented successfully by a group of older women in competition, and discuss the general exercise principles utilized to increase BMD in postmenopausal women.

This article aims to explain why integrating multiple tests such as Anaerobic Speed Reserve (ASR), Intermittent Fitness Test (IFT), and Maximum Aerobic Speed (MAS) can provide a comprehensive evaluation of soccer players’ fitness levels and help to design effective training programs tailored to their individual needs.

This excerpt from NSCA’s Guide to Sport and Exercise Nutrition briefly analyzes some of the research behind creatine and its application to sport performance.

This article explores strength training and conditioning programs designed to improve Physical Fitness Test (PFT) scores, strength, endurance, power, and combat readiness. Visit NSCA online to learn more about tactical athletes and strength.

Learn how to increase the body’s use of fat as a fuel without compromising the use of carbohydrates for higher-intensity training. Mike Nelson, PhD, explains how combining specific nutrition and exercise together affects the use of fat as a fuel, in this session from the NSCA’s 2017 Personal Trainers Conference.

There is growing evidence that polarized endurance training is a promising method for optimizing a tactical athlete’s cardiovascular system, preparing for physical performance tests, allowing for a more full recovery during deployment, and allowing for safer return to duty after injury or deployment.

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 discusses using the principle of specificity as an important component in tactical training programs to enhance performance, decrease injuries, and improve functional longevity of a tactical athlete.

Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
