The impact of physical activity in the: „Keep your body straight” program on the selected features of body posturę in frontal and transverse planes in children aged 7-9 years

Restitution of the Values of Body Posture Features in Sagittal and Transversal Plane after Carrying the Schoolbag on the Right or Left Shoulder and at the Heteronymous Hip and its Correlations with Physical Fitness Among 7-Year-Old Children of Both Sexes

“…The undertaken research is one of the few attempts to determine the restitution of static posture disorders [6][7][8][9][10][11]. It is an attempt to pay attention not only to the consequences of the weight, but also to the returning time to the habitual posture.…”

“…The problem of the influence of the weight on school supplies was investigated by Bogdanowicz [3], Hagner, et al [4], Annetts [5]. The conducted literature review showed that Mrozkowiak, et al [6][7][8][9][10] and Romanowska [11] dealt with the restitution of the values of postural features after loading with a schoolbag. Other authors like Bajorek, et al [12], Barczyk-Pawelec, et al [13], Dolata-Łubkowska, et al [14], Drzał-Grabiec, et al [15], Grabara, et al [16,17], Słoniewski, et al [18], Ślężyński, et al [19], Utake, et al [20], Wojtków, et al [21], Zeyland-Malawka [22], Żurek, et al [23] mainly studied the influence of specific physical work on selected values of posture features.…”

The Influence of the Weight of the School Backpack Carried on the Chest on the Body Posture Features in the Sagittal and Transversal Plane and its Relationships with Physical Fitness in 7-Year-Old Children of Both Sexes

“…The influence of the students' environment on their posture was investigated by Wandycz, et al [7][8][9][10][11][12][13], Romanowska [14], Annetts, et al [15], Mrozkowiak [16,17], Mrozkowiak, Żukowska [18], among others. Researchers usually focused on the role of the school chair and the table in student posturogenesis, ignoring the impact of carried school supplies.…”

“…Researchers usually focused on the role of the school chair and the table in student posturogenesis, ignoring the impact of carried school supplies. Early research by Mrozkowiak outlined the problem by exploring the impact of the load imitating a schoolbag on changes in selected spatial posture features and the subsequent restitution of the sagittal and frontal parameters of the spine and pelvis after the load removal [16]. The author's interest in the issues stems from the persistently high percentage of disorders of the body posture of students from the oldest preschool group and 1 st -3 rd grades of primary school, the constantly proclaimed opinion about the negative impact of the way of carrying school supplies on body postures, and the lack of clear recommendations about the optimal weight and contraindications against the negative way of carrying these utensils.…”

“…These programmes mostly last from 10 to 12 weeks during which exercise is performed 3 times per week. Positive changes are noticeable already after 6 weeks of intervention, when exercise is done 2 to 3 times per week and lasts 30 minutes (Emery, De Serres, McMillan & Côté, 2010;Lee, Park & Kim, 2013;Tomková & Palaščáková-Špringrová, 2013;Vetkasov, Hošková & Pokuta, 2014;Dewar, Love & Johnston, 2015;Kim, Cho, Park & Yang, 2015;Bendíková, 2016b;Mrozkowiak, Szark-Eckard, śukowska & Augustyńska, 2016;Łubkowska, Zdeb & Mroczek, 2015).…”
