    According to studies, physical exercise has a strong connection with learning and condition of human brain, and it has been linked with academic performance. Most of the studying in university is done while sitting down and very little active teaching methods are being used. The purpose of this master’s thesis is to study what type of students take part in a course that requires indoor cycling. The purpose of this master’s thesis is also to study the experiences of students practicing studying methods with physical activity in the course of neuroscience. This study examines the effects of indoor cycling on alertness, motivation and learning of the students and also the suitability of the method on individuals. The study was carried out as a qualitative case study and the research material was collected during autumn 2018. The research sample included six students from Open University of Helsinki. The study did not include the relevance of age and prior exercise background, albeit the information was asked in a background information form filled by the participants in the beginning of the course. The background information form was filled by 17 participants. Six participants were interviewed using semi-structured interviews and the research material was analyzed using a content analysis. The research results show that students with different ages participated in the course. The participants’ backgrounds regarding exercise were also diverse. The study also demonstrates teaching methods requiring physical activity increases the alertness, motivation and learning of almost all the students. The method is principally perceived as well suited and conducive to learning. Part of the participants felt the course content was so interesting that the method most likely had a positive effect on alertness and motivation.

    Aims. Mental disorders in adolescence are common, and when left untreated, they can significantly affect the developmental phase of adolescence, impacting development throughout life. Changes in experiencing emotions are typical in mental disorders, however, normal fluctuation of emotions in adolescence may impact the early detection of disorders in young people. Currently there is little research on the connection between temporal fluctuation of emotions and mental disorders in adolescence. This thesis is studying the variation in temporal fluctuation of emotions, mental alertness and self-control in adolescents that have at least one mental disorder, or no mental disorders, as well as the connection between such temporal fluctuations with different mental disorders. In addition, this thesis is studying the connection between the number of simultaneous mental disorders and the intensity of emotions, mental alertness and self-control. Methods. The studied group consisted 342 16–18-year-old adolescents from Helsinki, out of which 69.6% were girls. The data used in the study was part of the second stage of the SleepHelsinki! cohort study by the University of Helsinki. “MINI” interview technique was used for assessing the mental disorders and PsyMate™ application (which is based on the ESM method) was used for assessing the temporal fluctuation of emotions, mental alertness and self-control. The connections were examined with linear mixed models. Results and conclusions. The study did not detect any difference in the observed temporal fluctuation of emotions when comparing the adolescent that had at least one mental disorders with those that did not have any mental disorders. A greater number of detected mental disorders had a connection with weaker joyfulness and satisfaction, more intense depression, anxiety and irritability, as well as better experienced self-control. The number of disorders was not detected to have an affiliation with mental alertness. The study did not detect a systematic connection between temporal fluctuation of emotions and mental disorders, but some reference of connection between certain disorders and temporal fluctuation of emotions was detected. In the future it would be beneficial to study these connections while considering the impact of situational factors into emotions. 40 % of the adolescent observed in this study had at least one current mental disorder. Therefore, the common occurrence of mental disorders in the adolescent indicates the necessity to improve the understanding of the characteristic features of adolescent mental disorders, such as their impact in the changes in emotions.

    Aims. Sleep is very important for brain maturation in adolescence. However, the youth doesn’t often sleep enough. In adolescence evening preference in circadian rhythm becomes more common. This evening-type chronotype is often inconsistent with environment, such as early school mornings. In the long run this can lead into sleep deprivation which can then lead into low vitality, deficits in attention sustaining or some health problems for example. Also, evening-chronotype is associated with lower vitality, depressive and anxiety symptoms or health issues in adolescence. In adolescence it is also common to have unsteadiness of emotions. The aim of this study is to examine the associations between circadian rhythm and chronotype, vitality and emotions in adolescence. Additionally, the differences between genders in chronotype are also examined. Methods. 329 16–19-years old adolescents (69.9% girls) participated in the study for a week. The data used was from a Finnish cohort study SleepHelsinki!. The circadian rhythm and chronotype were assessed with actigraphy. Vitality and emotions were assessed three times in a day with a mobile application PsyMate™ which is based on Experience Sampling Method. The associations were examined with linear mixed models. Results and conclusions. In adolescence the circadian rhythm of girls is on average earlier than boys. Daytime low vitality is associated with less positive and more negative emotions in the same day. The association between low vitality and less positive emotions gets more intense as the study goes further. Chronotype as a continuous variable is not associated with daytime emotions or vitality in adolescence. Chronotype that is divided into three same sized groups is associated with daytime vitality as earlier chronotype is associated with lower daytime vitality. In adolescence the association between vitality and emotions should be paid attention to more, because vitality is something you might influence on with enough sleep. Guaranteeing higher vitality can also in the long run prevent mental health disorders since higher vitality could help stabilize emotions.
