Endurance Training: Aerobic Capacity and Threshold

Building Aerobic Capacity, Threshold, and Performance

Learn how to develop effective endurance-training programs that improve aerobic capacity, sustainable exercise performance, movement economy, fatigue resistance, and recovery through evidence-informed training methods.

Endurance Training and Conditioning is a comprehensive 5-CEC continuing education course exploring the physiological foundations of endurance performance and the practical application of aerobic conditioning, threshold development, interval training, and individualized exercise programming.

The course examines why endurance training involves much more than simply performing additional cardiovascular exercise. Fitness professionals will learn how maximal oxygen uptake (VO₂max), sustainable threshold characteristics, movement economy, and durability interact to determine endurance performance.

Special attention is given to understanding exercise intensity and the limitations of traditional heart-rate zones. Participants will learn why the term Zone 2 can describe different physiological intensities depending on the training-zone model and why exercise intensity should be prescribed according to the intended adaptation rather than an arbitrary number.

The course explores central and peripheral aerobic adaptations, including changes in cardiac output, blood volume, capillary development, mitochondrial content, and muscular oxidative capacity.

Fitness professionals will learn how to establish an aerobic base, develop threshold performance, integrate high-intensity intervals, and select appropriate training-intensity distributions.

Participants will also explore polarized, pyramidal, and threshold-oriented training approaches, with an emphasis on why no single distribution is universally superior for every athlete or fitness client.

The course provides practical programming examples for beginning exercisers, recreational runners, cyclists, and experienced endurance athletes, while emphasizing progressive overload, fatigue management, strength training, recovery, and professional scope of practice.
