Neural adaptations help mediate growth-related processes and the early increase in strength is attributable mainly to improved neural function. Along with neural changes, various aspects of the protein metabolism in the muscle are changing in the early phases of training.
Learn how diet and strength training in the absence of aerobic exercise can be used to improve body composition through simultaneous fat loss and muscle gain. In this session from the NSCA’s 2016 Personal Trainers Conference, Todd Miller demonstrates how to use body composition and metabolism measurements along with popular food tracking apps and activity monitors to design individualized diet and exercise strategies. CEUs available.
This article provides methods used by tactical facilitators, related research articles, and professional interviews to demonstrate how physical conditioning facilitates the transition from practice to duty for service members, including law enforcement and fire and rescue personnel.
The primary aim of this study was to systematically compare the effectiveness of blood flow restriction training (BFR) versus traditional resistance training (TRT) to improve muscle size in healthy adults. Secondary outcomes were improvements in muscle strength and endurance. We performed a systematic searchwithmeta-analysis. Using predetermined criteria, 541 unique articles were identified through databases and bibliographies. After screening titles, abstracts, and full texts, 20 articles were included in the review. All 20 articles evaluated muscle hypertrophy, 19 evaluated strength, and 1 evaluated endurance in response to BFR and TRT. Data from 10 articles were included in the meta-analysis. In the qualitative analysis, TRT and BFR increased muscle size without differences between conditions for at least 1 hypertrophy outcome in 13 studies, and TRT or BFR differentially improved hypertrophy in 5 studies. TRT and BFR increased strength without differences between conditions for at least 1 outcome in 15 studies, and TRT or BFR differentially improved strength in 9 studies. Results from the meta-analysis indicate no differences in muscle size (ES 5 0.045, 95% CI [20.278 to 0.367]) or strength (ES520.149, 95% CI [20.439 to 0.141]) improvements with BFR versus TRT. Practitioners can implement BFR training to increase muscle size and strength as appropriate, especially for training periods of 8 weeks or longer.
The expression of mechanical “muscle power” and the advanced training methodologies used to optimize it are explained by Duncan French in this session from the 2015 NSCA National Conference. By overviewing training strategies utilized with world-class athletes, this session links science with advanced training techniques designed to augment muscle power.

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.
