AB Background: the validity and reliability of the front plank test (FPT) have beenstudied in young adults but not in adults aged 34 to 60 years. The aim of this study wasto analyze the criterion-related validity and reliability of the front plank test (FPT) forevaluating trunk musculature in adults according to sex and age groups. Methods: arepeated measures design was used to study the reliability of the FPT. A total of 84 adultsaged 18–62 years performed trunk muscular force tests and the FPT. Criterion-relatedvalidity was assessed using repeated measures ANOVA. Reliability was examined byICC, error measurements, and Bland–Altman analysis across sex and age groups. Results:significant differences in the activation of the rectus abdominis and external oblique muscleswere found compared with the erector spinae and multifidus muscles (p < 0.001). Nocorrelations were found between FPT time and physical activity or rate of perceived exertionat the end (p > 0.05). Low and moderate correlations were found with body fat percentage,trunk fat mass percentage, and external oblique, regardless of sex and age groups (p < 0.05).Extremely high reliability was found regardless of sex and age groups (ICC > 0.98), with lowerror measurements (RMSE = 11.93–18.73; %CV = 4.91–6.33; SEE = 11.45–16.84). MDC90values indicated no real change between T1 and T2. Conclusion: FPT is a valid and reliabletest for assessing trunk musculature in adults regardless of sex and age groups.
