Objective: The present study aimed to establish a normative database of neck strength and endurance while exploring personal and work-related factors that can significantly influence the neck strength and endurance capacity. <br><br>Background: To our knowledge, little effort has been made to combine both personal (e.g., age, body-mass-index (BMI), and sex) and work-related (e.g., exertion type, exertion level, and time-of-day, i.e., diurnal variation) factors for a more comprehensive evaluation of neck strength and endurance capacity than either factor alone. <br><br>Methods: Forty healthy participants (20 males and 20 females) performed sustained-till-exhaustion head-neck exertions at their 50% and 100% of maximal efforts in anterior, anterior-superior, and posterior-superior directions while seated at neutral, 40° extended, and 40° flexed neck postures, respectively. Exertion force and endurance time data were recorded and analyzed using regression models. <br><br>Results: Overall,
