Abstract
Our research group has went on several intervention programs which were applied to infants, elementary school and junior high school students and university sports-club students and also people who suffered disaster of Hanshin-Awaji Great Earthquake in 1995. All intervention programs were performed and are now going on to promote mental and physical health. The current intervention program focuses on the intervention which is based on a newly constructed series-of-leaflets for promoting sleep health entitled “Three great benefits due to ‘Go to Bed Early, Get up Early and Do not Forget Breakfast!”. These leaflets consist of four versions for parents of small children, athletes, women and people who suffered great disasters. In this study, we would like to focus on the results of three intervention studies to promote the athletes who are the members of succor team of Kochi University held in November of 2008 (Takeuchi et al., 2012), 2010 (Wada et al., submitted) and 2011 (Wada et al., unpublished; Harada et al.,. unpublished). All the three kinds of intervention seem to be effective for athletes to change their chronotype into morning-typed one, promote the sleep and mental health and finally improve their performance in playing sports.
Highlights
This paper deals with the intervention programs which are educational methods to promote sleep and mental health and improve the sports performance of athletes
For the evening-typed participants who occupied 50% of all participants in Group 2 (G2) and Group 3 (G3), a significant and positive correlation was shown between the change in Trp amount consumed at breakfast and the change in M-E score before and after intervention (Fig. 3)
“A high concentration of serotonin in the brain and high concentration of plasma melatonin at night can induce earlier fall-in-sleep” (Fig. 1). This high melatonin-concentration can be depressed by the fluorescent lamps which are being used by most of all Japanese homes. 2.2.2 Participants and Methods The intervention program was administered to 94 subjects belonging to Kochi University soccer club. 63 subjects participated in the intervention program. They were divided into three groups (G1 [Photo 1-A], n = 20: no intervention; G2 [Photo 1-A], n = 22: asked to have protein-rich foods such as fermented soybeans and vitamin B6-rich foods such as bananas at breakfast and sunlight exposure after breakfast; G3 [Photo 1-B], n = 21: the same contents as G2 and incandescent light exposure at night)
Summary
This paper deals with the intervention programs which are educational methods to promote sleep and mental health and improve the sports performance of athletes. The main contents of the intervention are the tryptophan intake at breakfast and following exposure to sun lights. Incandescent light with lower color-temperature lights as lighting at night is recommended to keep melatonin secretion. The following four paragraphs are theoretical basements of these contents as intervention
