Gait detection and step counting using smartphone
Kočendová, Kateřina ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
The focus of this thesis is the detection of walking and running, followed by a step count. Testing is performed on signals of regular daily human activity that involve sections of running, walking or no activity. Those signals are logged using accelerometer in smartphone. The exact type of physical activity performed is distinguished by an average, variation coefficient and wave transformation methods. Basics statistic methods are used to quantify the number of steps taken during either walking or running. Algorithm for activity detection and algorithm for step counting are optimized and tested by a set of signals.

Habitual physical activity in Preschool children: Comparison of common Kindergartens and Forest Kindergarten
Zemlerová, Hana ; Procházka, Michal (advisor) ; Havlíčková, Michaela (referee)
The aim of the work was to objectively examine the physical activity of children in two different types of preschools, in forest kindergarten and common kindergartens. The theoretical part deals with the characteristic of movement in the preschool children, with factors influencing physical activity, the benefits for this age and the means for measuring objectively physical activity. Research is focused on one particular forest kindergarten. Pedometer was elected for measuring the examined physical activity. According to the results children in the forest kindergarten make more steps during their stay in school as well as overall per day than children in regular kindergartens. Conversely in the afternoon after leaving the nursery they are less active than the children from regular kindergartens. The most prominent difference in the level of physical activity between the two groups of children showed during their stay in pre-school facilities. Forest nursery could be a good alternative to preschool education in terms of sufficient physical activity.

Accurate pedometers function using the autocalibration
Kučera, Lukáš ; Slabý, Kryštof (advisor) ; Procházka, Michal (referee)
v angličtině Aim: The aim of this study is to explore the possibilities of accurate pedometer functions through a partial removal of individual measurement errors for a particular pair of pedometer- proband, using the auto-calibration of walking for the previously known distance. Methods: They will be used pedometers of mechanical type YAMAX SW-200 and fully electronic type OMRON HJ-720. Thirty adults from 18 to 69 years old (11 men, 19 women) took part in this study. In the pilot phase will be suggesting of a sufficiently long sections of known length (100 m, 300 m a 1000 m) and auto-calibration on a flat track. Own attempt will consist in landscaping measurement. Resulsts: From everage lengths and from the number of steps, which we measured, is possible to determine distance, which probands covered. The biggest aproach was to real distance 1000 m in case we used everage length of step from distance 300 m. In this case undervaluation of the distance reached in Omron 7 % and with Yamax just 10 %. Howewer the distance as well for Omron was overvalued in 27 % probands and for Yamax it was in 20 % probands. Conclusion: The best possibility seems to be average length of step, which is couted from distance for 100 m. Although there is undervaluation more frequent, overvalution is minimal. It will be...
