Applied Physical Program on Changes of Body Postures and Dynamic Spine Function in Female Secondary School Students

Abstract

The aim of research was to identify the changes of body posture and dynamic spine function of female secondary school students after adaption of physical program which was within lessons of physical and sport education. The research group consisted of 45 female students of the first year of secondary school in Žilina (age - 15.42 0.38 years; body weight - 55.13 3.69 kg; height - 167.82 2.51 cm; body mass index - 19.72 1.51). In terms of data acquisition methods, we applied standardized tests and methods. To evaluate the impact of adapted physical program on muscular and skeletal system of secondary school students within lessons of physical and sport education we applied Wilcoxon test (Wtest p < 0.01; p < 0.05). The statistical significance of differences between observed variables of pre-tests and post-tests, as practical and material significance, was evaluated by Effect size, Pearson’s - r. While evaluating the body postures, positive shifts of body postures were recorded (35 x), as it was noted with statistical significance and large effect size (p < 0.01; Z = -5.8413; r = 0.8694). Within the dynamic spine function, the evaluation detected all of the tests as statistically significant, but the left lateroflexion was recorded with negative effect size (p < 0.01; Z = -3.7271; r = -0.3217).
