Comparison of circadian typology and circadian rhythms of female pubescents - sportsmen and nonsportsmen
FIŠEROVÁ, Monika
Circadian rhythm is biorhythm. This rhythm influences activity of some organs and releasing of hormones. Effective alternation of activity and resting in organism is influenced too. Highest body temperature of human body is physiologically in evenings, in association with activity. Preference of evening typology in sportsmen can have negative impact for shortening of sleeping time and forming of sleep deprivation. This condition may cause quicker incidence of civilizing disease and diseases occurred in elderly, including psychological problems. There are compared two groups of girls in pubescent age, from 9 to 15 years old - sportsmen and nonsportsmen in this thesis. The main aim is to find out, if the sportsmen group is more evening typology. "Questionnaire of life rhythms and sleeping habits 9 - 15 years" (KREJČÍ, HARADA, 2010) was used in this study. There were collected 35 questionnaires from both groups. Evaluation was done by arithmetic mean and statistical tests were figured at University of Kochi by dr. Takeuchi, Japan. Girls of both groups don't show significant difference in morning or evening typology, but GS insignificantly show inclination for morning typology. GS eats regularly and has regular breakfasts. Girls of GS insignificantly showed worse results in mental health, than control group (KS). But better sleep quality showed GS. BMI was lower in GS. My prediction, that GS is tent to evening typology was not validated. Morning life style of the people with morning typology is more contributive for health. Duration of sleep of the girls of both groups is not sufficient in this age. Girls of GS sleep shorter time than KS. Program of intervention aimed to improve sleeping hygiene would be profitable for GS.
