1 Abstract Title: Effect of sitting posture on different seats on respiratory function while using a smartphone Objectives: The purpose of this thesis is to investigate respiratory function in sitting posture while using a smartphone. Another objective is to compare the values of monitored parametres and to determine which of the 3 performed experiments exhibite the greatest decreases in respiratory parametres. The last aim is to confirm the difference between female and male values and to show that men have higher values of monitored respiratory parameters and the greater decrease of respiratory function than women. Methods: 20 healthy young volunteers were recruited (10 women, 10 men). The experiment was carried out on three different types of seats - office chair, armchair and gymball. Participants spent time using a smartphone for one hour. To investigate changes in respiratory function, we measured FEV1, FVC, FEV1/FVC a PEF before and after each experiment was completed. Values were processed in MS Excel. Pair t-test and Wilcoxon test were used to evaluate the effect of sitting posture on respiratory function (p < 0,05) A two-sample t-test was used to determine a statistically significant difference in values in men and women, as well as in decrease of respiratory function in men and women. (p < 0,05)....
