Abstract

Background and Aims: The purpose of the present study was to investigate the strength, endurance, and muscles flexibility in Teenage wrestlers with and without hyper kyphosis.
Materials and Methods: In the current study, 40 wrestlers were purposefully selected and divided into two groups of with and without hyper kyphosis. Hyper kyphosis and endurance of extensor and flexor muscles of trunk were measured using flexible ruler, Sorensen test, and test of trunk flexion at 60 degree, respectively. The strength of extensor and flexor muscles were evaluated using a digital dynamometer and thoracoabdominal Flexibility was measured using functional test. To analyze the data, Pearson correlation test and independent T test were used.
Results: There were significant relationships among hyper kyphosis and strength of trunk extension (p=0.005), endurance of trunk extensor muscles (p=0.02), thoracoabdominal Flexibility (p=0.01), the ratio of trunk flexor to trunk extensor muscles strength (p=0.001), and the ratio of trunk flexor to trunk extensor muscles endurance (p=0.001). In addition, there were significant differences between the two groups in trunk extensor muscles strength (p=0.02), the ratio of trunk flexor to trunk extensor muscles strength (p=0.001), endurance of trunk extensor muscle (p=0.009), the ratio of trunk flexor to trunk extensor muscles endurance (p=0.005), and thoracoabdominal Flexibility (p=0.02).
Conclusion: The results showed that the changes in factors such as strength, endurance, and flexibility can aggravate the dorsal arch of spine and these factors in athletes, such as wrestlers, can be considered as abnormal despite being athletes. Therefore, coaches and athletic trainers should be trained to evaluate these factors and provide an effective training program.
