The Relationship of Saliva Microcrystalline Characterization and Contractile Duration of Skeletal Muscle in Medical Students

Sažetak

Aim: The aim of the study was to analyze the possibility of the diagnostic use of saliva investigation in relation to medical conditions among medical students, and provide a background of non-invasive physiological-based preventive measures for their health outcomes.
Methods: The study was conducted among 70 students from Danylo Halytsky Lviv National Medical University (Ukraine), who were asked for general information and interviewed about the subjects of lifestyle risk factors related to physical inactivity, circadian rhythmicity, the use of technical gadgets, and the presence of functional gastrointestinal disorders. Their saliva secretion and microcrystallization were evaluated. For detection of the microcrystallines of non-organic origin in saliva, X-Ray diffractional powder analysis was used.
Results: The results of the study indicated that 70% of students have decreased daily skeletal muscle contractile duration, circadian dysfunction and extended time of using gadgets all of which leads to changes in saliva secretion and the microcrystallization of biogeneous substances. About 30% of participants have signs of functional disorders of the upper gastrointestinal tract.
Conclusion: An integrative view on saliva microcrystalline changes could be a novel diagnostic tool for detection of early health disorders, and maintaining regular skeletal muscle contractile activity and normal circadian rhythmicity is a promising physiological approach to improve health outcomes in young people.
