Traveling can take a lot out of a person. Making a plan to prepare for pre travel, during travel, and time zone changes can help an individual manage the stress of traveling effectively. This infographic gives key information to help an individual prepare for eastward travel.

Plyometric training is a series of explosive bodyweight resistance exercises using the stretch-shortening cycle of the muscle fiber to enhance physical capacities, such as speed, strength, and power. These physiological measures translate to improved performance in many sports, including court-based sports, field sports, and water sports.

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.

Emily Zaler, Assistant Strength and Conditioning Coach for the National Football League (NFL) Denver Broncos, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the benefits of being persistent and proactively seeking out opportunities in the field. Topics under discussion include working with professional athletes, facing adversity head on, and how no task is too small to show how you can add value to a program.

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.

In this 2018 coaches conference video Todd Hamer describes his experience working with collegiate football players, and his methods for targeting appropriate energy systems to increase athletic performance in speed and conditioning.

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 article explains the connections between the upper and lower body and their influence on performance and recovery strategies in sprinting.
