This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

As a Strength and Conditioning Coach with the US Olympic & Paralympic Committee (USOPC), Jared Siegmund prepares athletes for the apex of achievement and perseverance. Siegmund shares that, contrary to public belief, the Olympic competition cycle is not every four years — Team USA athletes face fierce competition in World Series events along the way to qualify. He also speaks to the creativity required to coach Paralympic athletes, where missing limbs create unique biomechanics and hearing or visual impairments impact cueing. Siegmund touches on his principles-based programming architecture, sample adaptations, and USOPC’s interdisciplinary support team. Additionally, Siegmund and McMahon discuss the new generation of modern athletes who are more in tune with data and can control their preparation experience. The discussion concludes with the importance of a growth mindset and getting out of your comfort zone, as well as opportunities to enter elite sport.

This excerpt from Developing Speed describes an agility drill that aims to develop change of direction.

This Kinetic Select excerpt from Developing the Core describes how to perform the medicine ball twist variation as a rotational core movement.

Learn how to coach various weight room exercises and understand the differences of “intention” between the various levels of football. In this session from the NSCA’s 2017 Coaches Conference, Pete Bommarito dives into the details of building strength in the weight room for youth and early high school football players, how to maximize all aspects of speed-strength and power by heavy variable loading, and advanced techniques at the elite and professional levels.

Brett Bartholomew talks about the risks posed to athletes who are partaking in randomized and unstructured training practices often supervised by non-certified professionals. This session from the NSCA’s 2017 Coaches Conference will help you identify ways in which a “skills not drills” approach towards movement training design can not only lead to enhanced transfer of training to the competitive environment, but also better retention on behalf of the athlete as they progress through future training.

This article sheds some knowledge on shoulder exercise modifications and progressions that can help reduce the risk of re-injury and maximize performance for clients.

Using the sled closely mimics real-time sports performance movements and activities because of the horizontal resistance opposing the vertical movements typically seen in a weight room setting. This article highlights a variety of sled training exercises designed to target the core musculature.

This article addresses the implications and clinical applications of eccentric training. It also provides general exercise guidelines and future directions of eccentric training.

As rotation, power, and rotational power are all common pieces of everyday life, it is important to train for efficiency in the movements. This article addresses the specific approaches rotational training can have in an individual’s strength program to address core integrity, synergistic muscular systems, and overall athletic capabilities as it relates to aging.
