From the NSCA’s 2020 Coaches Conference, Scott Schultz and Beau Smith show hands-on drills for prehabilitation of the anterior cruciate ligament (ACL) to reduce the risk of injury in sport. These drills include posterior chain warm-up exercises, plyometric and balance exercises, and proper landing mechanics to reinforce proper hip and knee positions.

This Kinetic Select from NSCA’s Essentials of Personal Training, Second Edition gives a brief overview of respiratory adaptations, and how aerobic interventions of duration and intensity can be used for specific adaptations for endurance training.

The physiological response to breath holding includes bradycardia and peripheral vasoconstriction, which contrasts with that of exercise which includes tachycardia and peripheral vasodilation. This raises the question as to what the physiological response is to breath holding during exercise. During low-intensity exercise, the breath holding response of bradycardia and peripheral vasoconstriction prevails over the exercise response of tachycardia and peripheral vasodilation, but nevertheless the exercise may be sustained. Due to the lack of availability of extrinsic oxygen (O 2 ) from the atmosphere during breath holding, the energy demands can be met by increased reliance on intrinsic O 2 stores (i.e., O 2 that was in the body before the breath hold) via increased O 2 extraction at the muscle compared with exercise while breathing, or increased contributions from anaerobic energy systems. During high intensity exercise of short duration, the exercise response may prevail over the breath holding response due to the increased parasympathetic withdrawal and sympathetic drive of higher intensity exercise. If breath holding during high-intensity exercise was sustained for long enough, the breath holding response may eventually overcome the exercise response, although this may be difficult due to the inverse relationship between exercise intensity and breath hold duration.

From the 2021 NSCA’s Coaches Conference, Matthew Ibrahim, Co-Owner, Director of Strength and Conditioning, and Internship Coordinator at TD Athletes Edge, discusses how to help athletes develop the skills necessary to build the brakes in the athletic development process. Other topics covered include how to create a better understanding of the transfer from training in the weight room to sport performance.

This 2018 Personal Trainers Conference video features Lee Boyce going over the subject of anthropometry and the mechanics of the fundamental movements in strength training. Boyce describes the common issues you see and how to individualize movements for your clients.

Learn optimal setup, execution, and landing mechanics to maximize power output and to best prepare the joint structures to tolerate greater stresses later in training. In this session from the NSCA 2016 TSAC Annual Training, Loren Landow identifies progressions based on competency and ability—from low amplitude, bilateral jumps to single-leg deceleration drills.

Learn about middle school and high school strength and conditioning from 2022 NSCA Coaches Conference presenter Elton Crochran. Coach “Croc” shares his story about transitioning from collegiate strength and conditioning to his work as the Strength and Conditioning Coordinator at Randolph Field School District in San Antonio, TX. Crochran is currently the Head Strength and Conditioning Coach at Veterans Memorial High School. He talks about his hands-on coaching session from Coaches Conference, as well as developmental milestones across key stages of long-term athlete development.

The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.

This article provides a sample six-week lumbo-pelvic hip complex strengthening program with the intended goal of improving vertical jumping ability and landing mechanics without the addition of plyometric or jumping/landing drills.
