Comparing the physical prerequisites of competitive swimmers, relative to the preferences of swimming disciplines.
 Hanus, Tomáš ; Chvostek, Lukáš (advisor) ; Suchý, Jiří (referee)
Title: Comparing the physical prerequisites of competitive swimmers relative to the preferences of swimming disciplines. Objective: The objective of this bachelor thesis is to create a pilot study in which selected physical and anthropometric parameters of junior swimmers (16 to 18 years old) will be measured and compared. We compare short and middle distance swimmers against long distance swimmers. Methods: The research of this pilot study was carried out under the supervision of the supervisor and with the help of special devices lent by the Department of Physical Education. Summary tables and graphs were used for clear interpretation and comparison of results. Results: The measurement results show that endurance swimmers have an average of 2-3 % more body fat than sprinters. Swimmers focusing on short and medium distances, on the other hand, have an average of less than 1 % higher water-free ATH. This result was demonstrated in both girls and boys. The results of the spirometry measurements showed that the sprinters achieved a higher maximum expiratory velocity compared to the endurance runners. Vital lung capacity did not confirm any regularity of results. In this case, the boys were the better sprinters, while the girls, on the contrary, were the endurance athletes. The results were compared...

Measurement Of Physical Quantities And Their Long-Distance Transmission Using Lora Modules
 Smažinka, Petr
This paper discusses wireless transfer of physical quantities using the LoRaWAN network. Specifically, it acquaints readers with the problematics of long-distance carbon dioxide measurement and data transfer through the LoRaWAN network. The main goal is to describe particular components of a LoRa system that provides such transmission. This system is comprised of a carbon dioxide sensor attached to a LoRa module which sends its data to a LoRa gateway every two minutes. The gateway then resends the gathered information to a LoRa server where it is converted into a JSON format and sent to an API client. Afterwards, the data is uploaded into a database and it is put into context with preceding measurements utilising a graph. The system then compares the latest measurement with the set carbon dioxide concentration limit and displays the result using an array of red/green LED diodes, depending on whether the limit was exceeded or not.
