Chapter 3: Bioenergetics & the Science of Energy | NSCA CSCS Exam Prep

In this video, we break down Chapter 3 of the NSCA CSCS curriculum: Bioenergetics and the Science of Energy. This chapter is foundational for understanding how the body produces and uses energy during exercise and sport performance.

We cover the three primary energy systems, how they work individually and together, and how they apply to different types of training and athletic performance. This video is designed to help CSCS candidates, strength coaches, personal trainers, and exercise science students simplify complex physiology concepts and prepare for the exam.

Topics Covered:

What bioenergetics is and why it matters in strength & conditioning

ATP: structure, function, and role in muscle contraction

The Phosphagen (ATP-PC) System

The Glycolytic (Anaerobic) System

The Oxidative (Aerobic) System

Energy system interactions and overlap

Factors affecting energy system contribution (intensity, duration, recovery)

Practical applications for training design and performance

Whether you're studying for the CSCS exam or looking to better understand how energy systems drive athletic performance, this video will help you connect the science to real-world training.
