Abstract:
BACKGROUND: Flexion/extension trunk muscle endurance imbalance is
more clinically significant than isolated trunk endurance deficits. OBJECTIVE: This study provides reference values and correlates of
trunk flexion/extension endurance ratio among healthy young Nigerian adults. METHODS: A total of 208 volunteers participated in this study.
Static Back Extensors Endurance (SBEE), Dynamic Back Extensors Endurance
(DBEE), Static Abdominal Muscles' Endurance (SAME) and Dynamic Abdominal
Muscles' Endurance (DAME) were assessed following standard protocols. Data
was analyzed using descriptive and inferential statistics. RESULTS: The mean age, SBEE, DBEE, SAME and DAME were 22.2 ± 1.76 years,
78.3 ± 41.5 secs, 21.1 ± 9.69 reps, 39.1 ± 24.5 secs and
16.5 ± 15.8 reps respectively. Static and dynamic trunk flexion/extension
endurance ratio was 0.63 ± 0.50 and 0.86 ± 0.74 respectively. There
were significant differences in trunk static (0.81 ± 0.57 secs vs.
0.53 ± 0.42 secs; p= 0.001) and dynamic (1.04 ± 0.48 reps vs. 0.74
± 0.83 reps reps; p= 0.001) flexion/extension endurance ratio in men and women,
respectively. CONCLUSION: This study established a set of reference values for
static and dynamic trunk flexion/extension endurance ratios among healthy
young Nigerians. Men had significant higher trunk flexion/extension
endurance than women.
