Abstract
Background/Aims Hyperlordosis is associated with shortened hip flexor muscles,causing low back pain. The aim of this study was to investigate the effects of hip flexorstretching with and without abdominal exercises in individuals with hyperlordosis.Methods A total of 30 participants with hyperlordosis, aged between 20 and 30 years,were divided into three groups. Participants in the hold-relax group performed hold-relaxstretching for 10 seconds, five repetitions, on both legs. Participants in the abdominalhollowing group performed hold-relax stretching and added an abdominal hollowingexercise for 10 seconds a repetition, 10 repetitions a set for three sets. Participants inthe curl-up group performed hold-relax stretching and then performed curl-up exercisesfor 10 repetitions a set for three sets. The angle of lumbar lordosis, hip muscle length(degrees), percentage of maximum voluntary contraction of transversus abdominis andinternal abdominal oblique, external abdominal oblique, rectus abdominis, lumbar erectorspinae and multifidus muscles were investigated at pre-test, post-test and followed up 3days after the end of the intervention.Results Significant within-group differences were found in the angle of lumbar lordosisfor all groups (P0.05), muscle length of hip flexor, and percentage of maximum voluntarycontraction of the lumbar erector spinae and multifidus muscles in the curl-up group(P0.05). The significant difference between pre-test and follow up in the hold-relaxgroup and curl-up group reflects the retention of at least 3 days.Conclusions Hold-relax stretching can reduce the angle of lumbar lordosis and increasehip muscle length. In the curl-up group, the lumbar erector spinae and multifidusmuscles decreased. Therefore, performing curl-up exercises after hold-relax stretchingis recommended to decrease the angle of lumbar lordosis and percentage of maximumvoluntary contraction of lumbar erector spinae and multifidus muscles.
