Project-based learning for aerobic capacity and key components of distance running performance

It can be difficult for some students to comprehend maximal aerobic capacity (V̇o_2max) and endurance performance. We present a project-based learning example used in our advanced human physiology course. This project is based largely on a seminal paper but utilizes chapters from the course textbook and additional peer-reviewed studies. After we cover background information on topics such as muscle physiology, metabolic pathways, expired air analysis, V̇o_2max, and lactate threshold, students join one of three groups to prepare and deliver presentations. Those topics and groups are based on 1) history of V̇o_2max, 2) rate limiters of V̇o_2max, and 3) additional determinants of endurance performance. The instructor covered topics from the textbook on sports physiology including oxygen uptake at the onset, during, and after exercise. The course instructor also provided a brief review of sport-specific V̇o_2max and lactate threshold testing in hockey players. Students in the class agreed to hold one class period in the laboratory for direct use of expired air analysis. The lab emphasized the relationship between intensity and carbohydrate versus fat utilization. During the project presentations in the final week of class, group 1 summarized key points such as the use of a Douglas bag and the difference between V̇o_2max and V̇o_2peak, while group 2 summarized central (e.g., cardiac output) versus peripheral (e.g., muscle mitochondria) limitations, and group 3 summarized other key factors for endurance performance such as lactate threshold and running economy. This project-based assignment was an excellent way for students to better comprehend V̇o_2max and endurance performance.NEW & NOTEWORTHY This project-based assignment provided students a unique way to comprehend human metabolism, cardiorespiratory and muscle physiology, and applied exercise science concepts such as maximal aerobic capacity (V̇o_2max), lactate threshold, and running economy. Topics covered during this assignment are important for health, performance, and longevity. Students were excellent at working in small groups, basing presentations on peer-reviewed literature, and applying their communication skills. Students strongly agreed with "teaching methods" and scored well on final exam questions related to the project.
