Lumbar curve (LC) and sacral slope (SS) angles were measured in standing with a mobile phone application (iHandy level). Anthropometric, physical activity\/inactivity levels (leisure-time sport involvement and sitting hours\/day) and abdominal (plank prone bridge test) and paraspinal (Sorensen test) isometric muscle endurance measures were collected. <\/jats:p><jats:p> Results: LC and SS angles correlated significantly ([Formula: see text], [Formula: see text]). Statistically significant differences for both LC ([Formula: see text]) and SS ([Formula: see text]) angles were identified between the male and female participants. A significant negative correlation was identified between the abdominal endurance time and LC ([Formula: see text], [Formula: see text]); however, the power of this result (56%) was not sufficiently high. The correlation between abdominal endurance and SS was non-significant ([Formula: see text], [Formula: see text]). In addition, no significant associations were identified between either of the sagittal lumbopelvic angles (LC\u2013SS) in standing and the participants\u2019 body mass index (BMI), paraspinal endurance, leisure-time sport involvement or sitting hours\/day. <\/jats:p><jats:p> Conclusion: The potential role of preventive exercise in controlling lumbar lordosis via enhancement of the abdominal muscle endurance characteristics requires further confirmation. A subsequent study, performed in a larger population of more diverse occupational involvement and leisure-time physical activity levels, is proposed.
