It is important for coaches to understand the relationship between commonly measured variables (e.g., displacement, velocity, and force) and their relationship to the derived variable of power.

Accentuated eccentric loading (AEL) can be combined with lower-body power-based movements to acutely enhance them; however, currently, there are limited recommendations for this training method. AEL can enhance force and power metrics during its utilization with lower-body power based exercises. When using AEL, exercises should consist of jump squats and countermovement jumps with loading methods consisting of weight releasors or dumbbell hand release. Elastic bands can be used; however, more research is needed in this area. External loads ranging from 10–30% of body mass can be used. Future research needs to investigate increased eccentric and concentric loads when using AEL with power based movements.

Hear from strength and conditioning coach, Tim Caron, on his path from collegiate strength and conditioning into a unique private sector business model in the Los Angeles, CA area. Caron connects with NSCA Coaching and Sport Science Program Manager, Eric McMahon, to discuss the potential role of sport science in the private sector with general population clients. This episode is full of training insights for coaches to re-engage their thought process around working with groups and teams. In addition, Caron shares the origins of his new book, Strength Deficit, on considerations for concentric and eccentric strength training.

Preventing injury, such as patellar tendinopathy, for athletes can be done through using various volumes, loads, contractions, and equipment in the off-season. The following info-graphic shows exercises and techniques to help with patellar tendinopathy.

Some positions within the fitness industry can be tricky to classify. This article helps businesses decipher the difference between a hired employee and an independent contracted position.

Deceleration in court and field sports, such as football and soccer, is an important component of speed and agility. This book excerpt looks at how to train for effective deceleration.

The evaluation, treatment, and management of concussions are an ongoing evolution in sports injury management and medicine. Strengthening the neck and shoulder region has been one way of trying to reduce head and neck injuries.

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.

For those dealing with clients who have back pain, this article focuses on non-specific low-back pain and potential exercise solutions for it.
