The field of exercise science was significantly shaped by events in the mid-20th century, including the formation of the American College of Sports Medicine and the 'runner's boom.' Early research, like that from the Harvard Fatigue Lab, focused on a holistic view, but a historical fear of strength training, partly due to figures like George Winship dying young, led to its marginalization for decades. This historical bias influenced common assumptions about exercise, often favoring endurance over strength.

Impact: Medium. Understanding the historical biases in exercise science is crucial for dismantling outdated assumptions and adopting a more balanced, evidence-based approach to fitness.
