Lecture 1: Upper Respiratory Tract Infections and Physical Activity

J-curve nieman

The curve follows the shape described in Nieman & Wentz (2019): URTI risk is reduced ~40–50% in the moderate exercise zone compared to sedentary individuals, then rises sharply with heavy exertion to 2–6× above normal — matching the values cited in the paper for post-race illness incidence.
