In this session from the 2017 NSCA National Conference, Mike Stone explains what rate of force development (RFD) is, how it is derived, and the underlying mechanisms affecting RFD.

This infographic explains the acute and chronic responses of velocity-based training (VBT). This is the third and final infographic of a three-part series explaining the theory behind and application of VBT.

Studies support the use of kettlebells for improving power, although evidence for using them to improve strength and aerobic fitness is still equivocal. Studies investigating the biomechanical properties of kettlebell training have been fruitful, and it may be useful for developing sprint running performance and for injury prevention.

This excerpt from NSCA’s Essentials of Sport Science highlights the importance of quantifying training load for both programming and monitoring an athlete’s progression or regression over time.

If manipulation of the training variables is not tailored correctly to the desired adaptations and specific training goals, an athlete can experience symptoms of nonfunctional overreach. If this process continues, the athlete can develop overtraining syndrome.

The Terry J. Housh Outstanding Young Investigator Award is given in recognition of a researcher who has been in the field for seven years or less.

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.

Dr. Lorena Torres Ronda, co-editor of the new NSCA’s Essentials of Sport Science textbook, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about creating the textbook and how the Certified Performance and Sport Scientist® (CPSS®) certification will benefit the field. Topics under discussion include the use of technology in sport and the specific role that strength coaches play in supporting better performance and recovery decisions.

Former President of the NSCA Greg Haff talks about how views on periodization have changed, and the importance of periodization for coaches and athletes to see consistent performance, in this 2018 National Conference video.

This infographic summarizes the National Strength and Conditioning Association’s (NSCA) position statement for resistance training for older adults and the benefits, program suggestions, and considerations specific to them.
