Using wearables to monitor physical activity
Mádlová, Zdenka ; Větrovský, Tomáš (advisor) ; Omcirk, Dan (referee)
Title: Using wearables to monitor physical activity Objectives: The aim of this study is to assess the validity of the Fitbit Charge 5 compared to the ActiGraph wGT3x-BT for the assessment of physical activity (steps, time spent in moderate physical activity, vigorous physical activity and moderate to vigorous physical activity) in adults. Methods: The Fitbit Charge 5 commercial physical activity monitor was compared to the ActiGraph wGT3x-BT under daily living conditions. Healthy adults (n=32) wore both devices in a 7-day field study. Data were analyzed based on days for steps, minutes of moderate physical activity, minutes of vigorous physical activity and minutes of moderate to vigorous physical activity. Pearson's correlation coefficient and Bland-Altman plot were used to assess the correlation between the Fitbit Charge 5 device and the criterion. Mean percentage error (MPE) and mean absolute percentage error (MAPE) were calculated to assess differences. Results: The Fitbit Charge 5 had a very strong correlation (r = 0,94; 95% CI 0,92- 0,96) on the step measurement with criterion. The MAPE value was 23%. A weak correlation with respect to the criterion was demonstrated for the measured physical activity of moderate intensity (r = 0,33; 95% CI 0,27- 0,39). For vigorous physical activity a...

The amount of physical activity within a week's routine of football players at grade level.
Zelený, Jan ; Kokštejn, Jakub (advisor) ; Frýbort, Pavel (referee)
BIBLIOGRAPHICAL IDENTIFICATION Title of Bachelor work: The amount of physical activity within a week's routine of football players at grade level Place of work: UK FTVS Author: Jan Zelený Field of study: Physical education and sport Head of work: Mgr. Jakub Kokštejn, Ph. D. Defence year: 2013 Abstract Aims: The main aim of the thesis was the analysis of the amount of one week's physical activity (PA) of boys at adolescent age within regularly exercised PA. Methods: One week's routine PA was monitored by methodology which is based on measurement of the energy output, amount of steps and hops, and load intensity by ActiGraph GT3X accelerometer. Conclusions: The research showed that average daily amount of steps within selected group of young people was 9284. Furthermore, the research showed that the average energy output was significantly lower, i.e. 30% lower than the specified health limits. At the same time, the recommended values of PA of middle and higher intensity were surpassed. At the last part of the thesis, the results were compared with the health recommendations for particular age category and the specified hypotheses were then verified. Key words: Physical activity, adolescent, accelerometer, ActiGraph, football
