Abstract
Background: The hamstring muscles are primarily the flexors of the knee and can also take part in the extension of the hip and require a good degree of flexibility to do so. The sit-and-reach test is a field test used to measure hamstring and low back flexibility.
Aim: This study was aimed at evaluating hamstring flexibility among undergraduates of the University of Benin. Method: This ex-post-facto study recruited 400 volunteers (200 males and 200 females) healthy undergraduates, aged between 17-30 years old. A tape measure and digital weighing scale were used to collect data for the selected anthropometric variables -Height, Weight, BMI, Upper limb length, Lower limb length, and Trunk length. Sit-and- Reach test was performed on a mat; agoniometer was used to assess for Active Hip range of motion. Data collected were summarized using descriptive statistics of mean and standard deviation, An Independent T-test was used to ascertain the difference between males and females for the Sit-and-Reach test and Active Hip range of motion, and A Pearson’s product-moment correlation was used to examine the relationship between some anthropometric variables on Sit-and-Reach test and Active Hip active range of motion. Level of significance was set at 0.05. Result: The findings revealed that there were no significant gender differences in Sit-and-Reach test scores (p=0.063) and Active Hip Range of Motion (p=0.096). There was positive significant
correlations between sit-and -reach test scores and Upper limb length (p=0.0001), lower limb length (p=0.0001) and trunk length (p=0.005), and between Active Hip Range of Motion and height (p=0.0001), lower limb length (p=0.0001) and trunk length (p=0.005), There was positive significant correlation between BMI (P=0.004) and active hip range of motion but no significant
correlation with Sit-and-Reach test (p=0.258), trunk length (p=0.143) showed no significant correlation with active hip range of motion. Height showed no significant correlation with both tests.
Conclusion: This study provided the average value of hamstring flexibility among male and female were within the normal range. Anthropometric factors such as upper limb length, lower limb length, BMI and trunk length correlated with hamstring flexibility among Nigeria adults. However, the pattern of correlation varies between sit and reach test and active hip range of motion. There was no significant correlation between height and both tests.
