Verification of metabolism prediction based on performed activity
Kopecký, David ; Pokorný, Jan (referee) ; Kopečková, Barbora (advisor)
Nowadays, metabolic rate or energy expenditure in general is one of the most discussed topics, especially in connection with a healthy lifestyle. Nevertheless, the metabolic rate can be used as a relatively accurate indicator of physical or thermal load as well. Usually, the value of metabolic rate is used as input into various physiological models. These models estimate the body’s thermal stress, for instance when working in a protective suit. The thesis deals not only with tabulated values of metabolic rate, but it also focuses on the accuracy of estimated metabolic rate using simple measuring devices. The Apple Watch Series 4 smartwatch, the Garmin Fenix 6 Pro Glass sports tester, and the Fitbit Inspire smart sports bracelet were used for the measurements published in the thesis. The results of the measurements show that contemporary sports testers are still inappropriate for use in healthcare or elite sports.

Sporttester with Bluetooth LE
Blažek, Vojtěch ; Komosný, Dan (referee) ; Krajsa, Ondřej (advisor)
This thesis deals with the design of a sporttester, which is a device capable of calculating the cadence of the taken steps and monitoring the impact force of foot on the ground while running. Exposure to long-term strong impacts while running can cause serious fatigue fractures of the hip, calf bone or the foot area. The purpose of the sporttester is to monitor and signal strong impacts to the runner, thus helping to prevent fatigue fractures. The aforementioned features are evaluated based on the change in acceleration measured by the accelerometer. The calculated values of step cadence, running speed and impact force are sent via Bluetooth Low Energy to a compatible mobile application.

Validity of commercially available smartwatches when estimating energy expenditure
Kopecký, David ; Pokorný, Jan (referee) ; Řehák Kopečková, Barbora (advisor)
Metabolic rate is an energy quantity. Its value is a key input not only in thermophysiological models, but also in the calculation of heat stress indices or complex models predicting a person's thermal sensation. With the dynamic development of technology, sporttesters are able to estimate energy expenditure, among other things. It is a non-invasive method of estimating energy expenditure, or metabolic rate, using associated body functions to predict it. This work deals with the validity of the accuracy of metabolic rate estimation using the Garmin Fenix 6X Pro sporttester in comparison with indirect calorimetry. The accuracy of the metabolic rate estimation was tested for the activities of lying down, administrative work and cycling with regulated mechanical resistance of 100 and 150 W. 15 male subjects aged 28 ± 5 years, with a weight of 83.2 ± 13.5 kg and a height of 180 ± 7 cm participated in the study. In terms of the results, it is possible to observe a lower accuracy of prediction of metabolic rate for low-intensity activities, with the resulting MAPE being around 19-43 %. On the other hand, for activities with moderate activity, the prediction of the metabolic rate by the used sporttester proved to be sufficiently accurate, with a resulting MAPE in the range of 6–8 %.

Testing of maximal heart rate in swimming flume
Hubička, Tomáš ; Jurák, Daniel (advisor) ; Chrzanowská, Babeta (referee)
Title: Testing of maximal heart rate in a swimming flume Objectives: Pilot study using the methodology for testing the maximum heart rate in swimming flume, functioning as a swimming trainer. An alternative method for determining maximum heart rate by each swimmer. Methods: Due to the basis of the pilot study, a methodology for heart rate max. testing was created. A sample of probands was chosen to study Physical Education and Sport of the students who are former or still active swimmers. A sporttester was used to detect a heart rate. Data processing was made by Polar Precision Performance programe. For the submaximal swimmer speed detection probands went through a CSS test. Speed obtained from this test was further used for warming of probands before the graded strain test started up to the maximal heart rate of probands. Results: By the CSS test is obtained the individual speed of swimming at the ANP level of each of the probands in meters per second. This was further used as the speed for warming in the graded test up to the maximal heart rate of probands. The results are showing that four of six probands reached the maximum heart rate level in comparison with a theoretical calculation of the maximum heart rate. Key words: swimming flume, swimming speed, maximum heart rate, Critical Swim Speed,...

Floorball goalkeeper conditioning
Koráb, Jakub ; Křiček, Jan (advisor) ; Tůma, Martin (referee)
The title of the work: Floorball goalkeeper conditioning The aim of the work: Based on the identified needs for floorball goalkeeper conditioning the diploma thesis deals with composing the manual for stimulating their specific demands. Methodology: The essentials of the work are both foreign and Czech literature searches dealing with the given issue, measuring functional ability with a sporttester and maximum heart rate laboratory measurement. Based on floorball goalkeeping functional requirements two main areas of stimulation have been defined - speed and speed endurance. The work has been consulted with the renowned conditioning trainers - namely e.g. Josef Bruk (ice hockey goaltending), PhDr. Aleš Kaplan (basketball, football, athletics) and PaeDr. Miroslav Špalek (football goalkeeping, tennis). Outcomes: Measured values of heart rate during floorball goalkeeping performance have reached over 70 % of goalkeepers' maximum heart rate. The measured data show high demands on conditioning component of floorball goalkeeping and the need for its continuous improvement for better performance. As with growing heart rate combine some negative impacts on performance - tiredness and concentration problems. It is possible to influence versatile fitness, adapt organism to physical load and develop specific...

Smažinka, Dalibor ; Kovářová, Lenka (advisor) ; Bílý, Milan (referee)
Name: Analysis of the current state of training records in triathlon Objectives: Find out the forms of collection, registration and analysis of training data among contemporary triathletes in Czech Republic. Methods: The method of searching domestic and foreign sources was used in the work to create a longitudinal overview of the forms of collection, registration and analysis of training from history to the present. Subsequently, research was conducted in the form of a questionnaire survey on a sample of triathletes in order to determine the actually used functions of these tools (Survio application, CAWI method). 184 respondents completed the survey (return rate 64.8%); 77.2% of men and 22.8% of women aged 37.2 ± 11.97 years. The research group was selected by purposeful selection among hobby and elite triathletes in Czech Republic (72% of hobby and 28% of elite). Results: The rate of using the electronic form of monitoring and recording data from training and competitions is higher for the elite group of triathletes. (elite 93,8%, hobby 81%). At the same time, this group monitors data in their training more often than in the race and uses the training plan more often than hobby triathletes. The advanced features offered by the applications are used almost identically by both groups. The use of...

Zjišťování maximální tepové frekvence u vybrané populační skupiny zátěžovým testem
Vašková, Petra
The aim of this thesis was to measure maximum heart rate (HRmax) of selected group of volunteers using sport testers. The group consisted of 20 adults (10 women and 10 men) in average age 25.4 SD 2.44 years, average height 171.75 SD 7.99 cm, average weight 69.2 SD 11.08 kg and average BMI 23.33 SD 2.59 (kg/m2). All tested persons were subjected to stress tests on treadmill inSPORTline Gallop (Czech Republic), which tested HRmax (1 km long stress test with 4 ° belt inclination, 1 km long stress test with 6 ° belt inclination, the stress test presented by 1 km run and the graded exercise test). During testing, the heart rate of the runners was measured by the elastic chest band and it was displayed on the SIGMA SPORT RC 14.11 device. Probands ran into Vita Maxima - a state of subjective exhaustion. It was found that for a sample of 20 patients, the selection of the stress protocol did not have statistically significant effect on the values of HRmax. During investigation of the relationship between 10 selected prediction equations for calculating the HRmax, they were found out to be 100% interchangeable. It was found out that the HRmax values obtained by performing stress tests on treadmill and HRmax values calculated using predictive equations for calculating the HRmax differ significantly in terms of statistics. The study confirmed the influence of age to be the factor that affects HRmax the most significantly. The influence of the fitness index and sex on HRmax values was not confirmed in this study.
