Master Thesis

Étude du comportement physique chez des élèves de lycée

Abstract : Positive effects of physical activity are widely known. However, only a minority of adolescents have sufficient levels of physical activity to really benefit of physical activity. Similarly, the deleterious effects of a sedentary lifestyle are well documented, but our lifestyles seems to be increasingly sedentary. The objective of this master thesis is to carry out a one-week accelerometric follow-up of the physical behavior of students in the second year of secondary school in order to better understand it and to be able to carry out preventive actions. 126 students were monitored during one week using an accelerometer (Actigraph WGT3X-BT). We found very low levels of physical activity : only 23% of the students reached 60 minutes of moderate to vigorous physical activity and very high levels of sedentary time : less than 1% of the students spent less than 7 hours in a sedentary state. School physical education allows a large majority of students to reach the physical activity recommendations (84.4 33.5 min) which is significantly higher than on other days (p<0.001). In a cluster analysis, we did not observe significant differences according to gender, BMI or preferred ways of commuting (p>0.05). It seems necessary to set up interventions to make all students aware of this issue of physical behaviour and PE seems to be a very interesting ally because of its compulsory nature. The conclusions of this master thesis must obviously be placed in the context of the particular health context and its restrictions affecting the behavior of adolescents.
