A total of 314 road runners participated in the study, and a regression model was formulated to measure the relationships among variables in the conceptual model. The results revealed that perceived ease of use, perceived usefulness, and health anxiety had a significant impact on attitude toward use. To increase individuals’ intention to use smart wearable devices, it is critical to encourage a positive attitude toward using the devices to acquire health knowledge. Emphasizing devising effective means to communicate the health utility of the devices to customers should be the highest priority for industry producers.
