Abstract
Objective: Different timing of performing stretching and strengthening exercises can have different effects on the condition of Lower Crossed Syndrome (LCS). This study aims to compare the effects of eight-week training using stretching and strengthening exercises intermittently and simultaneously on the status of LCS in female college students. Methods: In this quasi-experimental study, the study population consists of 300 female students of Guilan University aged 19-25 years. To assess LCS, the New York Posture Rating tool was used. 120 patients who had hyperlordosis were re-evaluated using flexible ruler for precise measurement of LCS. Finally, 45 students with a lumbar curvature angle of >45 degrees were selected and randomly divided into three groups of intermittent training (n=15), simultaneous training (n=15), and control (n=15). The training program consisted of corrective exercises for 8 weeks, 3 sessions per week, each for 60 minutes. One-way ANOVA was used for data analysis in SPSS v. 20 software Results: The difference between the intermittent training and control groups was significant (P=0.30), while no significant difference was observed between the simultaneous training and control groups (P=0.68). Conclusion: Performing stretching and strengthening exercises intermittently has a greater effect on reducing LCS than performing these exercises simultaneously.
Highlights
Introduction ower CrossedSyndrome (LCS) resulting in S-shaped posture of the lower back [1]is characterized by tightness and shortness of hip flexors and spinal muscles and weakness of the abdominal and serine muscles (Figure 1) [2]
Kaleh and Gijareh studied the prevalence of Lower Crossed Syndrome (LCS) in school children aged 15-13 years and found that these children have a pattern of muscle imbalance due to sitting for long hours during the day [8]
This study aims to compare the effect of eight-week of training program using two different stretching and strengthening exercises on the status of LCS in female college students
Summary
Kaleh and Gijareh studied the prevalence of LCS in school children aged 15-13 years and found that these children have a pattern of muscle imbalance due to sitting for long hours during the day [8] These postural abnormalities seem to be a simple muscle imbalance, but may put a lot of pressure on the country’s economy due to causing people to be unable to do daily tasks [14]. Due to the lack of research on the timing of stretching and strengthening exercises and its effect on LCS and considering the importance of this issue in everyday life, the question that arises is: which of the intermittent and simultaneous exercises can have a greater impact on improvement of LCS In this regard, this study aims to compare the effect of eight-week of training program using two different stretching and strengthening exercises (intermittent and simultaneous) on the status of LCS in female college students
