Abstract:
BACKGROUND: Despite the popularity of core stabilization, there is
limited evidence as to the relationship between performance on tests of
isometric trunk muscle endurance and physical activity levels in adults. OBJECTIVE: To investigate the relationship between isometric trunk
muscle endurance and physical activity related energy expenditure in healthy
young adults. METHODS: A total of 51 participants (24 female) participated in the
study. Median age and body mass index were; 22 years (Min-max: 18-26 years)
and 21.8 kg/m2 (Min-Max: 18.59-28.98 kg/m2), respectively.
Participants completed the International Physical Activity Questionnaire.
Isometric trunk muscle endurance was assessed with holding times of
isometric trunk flexor, extensor, and lateral side bridge tests. Collected
data were summarized based on median and interquartile ranges. The
Spearman's correlation test was used to ascertain the relationship between
isometric trunk muscle endurance and physical activity related energy
expenditure. RESULTS: There were no gender differences in holding times of the
trunk flexor and trunk extensor endurance tests (p> 0.05). Males showed
higher endurance scores for side bridge test than females (p< 0.001). No
difference was found in physical activity related energy expenditure between
males and females. No correlation was observed between isometric trunk
muscle endurance and physical activity related energy expenditure for either
females or males (p> 0.05). CONCLUSIONS: According to our findings, trunk muscle endurance is
not related to physical activity related energy expenditure in healthy young
adults.
