In this short video, we briefly discuss constraints & and the constraints-led approach. In 1986, Karl Newell proposed the original constraints model, which sought to explain how coordination emerges from the interaction of constraints classified as the organism/individual, environment, and task, which operate at varying time scales. His interests were in understanding the development of infants and children (Renshaw et al., 2019).
Dr. Newell’s original model gave rise to the constraints-led approach (CLA). Applied to sports, Davids et al. (2008) suggested that task constraints were reflective of things like rules, equipment, boundaries, opponents, and teammates; environmental constraints reflect things like light, humidity, temperature, and social expectations; and individual constraints reflect things like height, body weight, motivation and fatigue levels (Yearby et al., 2021).
