This bachelor's thesis analyzes the relationship between daily physical activity, physical fitness, and nocturnal autonomic and metabolic regulation of healthy individuals. The study utilizes data from ten days of continuous ECG and glucose monitoring (CGM) collected from 60 participants. Using linear mixed-effects models, the analysis showed that, within the studied cohort, a greater amount of time spent in vigorous physical activity was associated with reduced nocturnal parasympathetic activity and increased sympathetic tone. No significant effect of daily physical activity on nocturnal metabolic regulation was observed in the studied cohort. The results further suggest that individuals with higher cardiovascular fitness exhibited a more stable nocturnal glycemic profile, characterized by a longer time spent within the target glucose range.

Studentka prezentovala výsledky své práce a komise byla seznámena s posudky. Dr. Chmelík položil otázku zda se jedná o věřejný dataset, jaké jsou obecná doporučení s těmito výsledky práce. Dr. Jurajda se zeptal proč byly u boxplotů vyjádřeny průměry, jaký artefakt může vznikat ve spánku se senzorem pro glykémii. Studentka obhájila bakalářskou práci a odpověděla na otázky členů komise a oponenta.
