The beneficial effects of regular physical activity (PA) on cognitive functions have received much attention. Recent research suggests that regular PA may also enhance creative thinking, an indispensable cognitive factor for invention and innovation. However, at what intensity regular PA brings the most benefits to creative thinking remains uninvestigated. Furthermore, whether the levels of regular PA affect the acute PA effects on creative thinking is also unclear. In the present study, using a previous dataset that investigated the effects of an acute bout of aerobic exercise on creative thinking in healthy Japanese young adults (22.98 ± 1.95 years old) in the year 2020, we tested the association between different intensities of regular PA (i.e., vigorous, moderate, and walking) and creative thinking with the cross-sectional baseline data using multiple linear regression. We also investigated whether regular PA levels were associated with the acute aerobic exercise intervention effects on creative thinking. The results showed that cross-sectionally, the regular PAs were differentially associated with divergent but not convergent thinking. Specifically, whereas the amount of vigorous-intensity PA was positively associated with fluency and flexibility, the amount of walking was positively associated with novelty on the alternate uses test (AUT) measuring divergent thinking. Importantly, the explained variances of fluency, flexibility, and novelty were 20.3% (p = 0.040), 18.8% (p = 0.055), and 20.1% (p = 0.043), respectively. None of the regular PAs predicted convergent thinking (i.e., an insight problem-solving task), nor were they associated with the acute aerobic exercise intervention effects on divergent and convergent thinking. These findings suggest that engaging in regular vigorous-intensity PA and walking may be useful strategies to enhance different aspects of divergent thinking in daily life.

Background:This longitudinal study aimed to examine if a Movability Index (MI), based on objectively measured built environment characteristics, was a determinant for objectively measured physical activity (PA) among young adults.Methods:Data collected from 177 persons participating in the Danish part of the European Youth Hearth Study (EYHS) was used to examine the effect of the built environment on PA. A MI was developed using objectively measured built environment characteristics, and included residential density, recreational facilities, daily destinations and street connectivity.Results:Results showed a positive cross-sectional association between MI and PA. PA decreased from baseline to follow-up. MI increased, primarily due to participants relocating to larger cities. An increase in MI from baseline to follow-up was associated with a reduced decrease in PA for females.Conclusions:Our findings suggest that the built environment is a determinant for PA, especially for females. The found gender differences might suggest the need to develop gender specific environmental indices in future studies. The validity of the measures can be further improved by creating domain specific PA measures as well as domain specific environmental indices and this can potentially reveal more specific built environment determinants for PA.

BACKGROUND AND AIMS Smart phones usage is rapidly progressing day by day in young adults’ lives who have become habituated and less indulged in physical activities. Thus, this study is aimed to measure the impact of internet-enabled smart phones on physical activity of students. METHODOLOGY An online cross-sectional survey was conducted among students aged 18-30 years studying in tertiary institutions. Internet-Connectedness Index and International Physical Activity Questionnaire-Short Form were formulated in the Google Docs and distributed to participants via email or social media applications. RESULTS A total number of 252 students participated in study revealed that majority of users have own computer for prolonged time with broadband and 3G internet. Only (4.4%) participants have performed vigorous and (5.6%) moderate activities 7 days a week. Whereas (27.8%) participants spent their time sitting at desk, visiting friends, reading, sitting or lying down to watch TV for <2 hours (27.8%), <4 hours (21.8%) while >8 hours (23%) respectively. This showed that with the increased use of internet, young adults performed low physical activity. CONCLUSION It was concluded that majority of young adults have used internet for prolonged time on computer/laptop/cell phones whereas limited participants reported to have regular physical activity however, no significant association was found between the impacts of internet-connectedness with physical activity.

ABSTRACT: THE EFFECTS OF PERSONALITY TRAITS ON PHYSICAL ACTIVITY Indonesia was considered as a country who has low physical activity. Hence, it was necessary to promote physical activity in order preventing degenerative disease and death in young adults. Personality traits were good predictors of physical activity. The purpose of this study was to examine the effects of personality traits on physical activity. This is a survey analytical study cross-sectional design on 33 samples aged 18-26 years old. The study found that personalities traits influenced physical activity with contribution 32% (p≤0,05), especially of extraversion, agreeableness, and openness. There was significant difference of physical activity based on gender and exercise routine, this should be a consideration for further research.  Keywords: Personality Traits, Physical Activity, Gender.  Indonesia dianggap sebagai negara dengan aktivitas fisik yang cukup rendah, sehingga diperlukan promosi aktivitas fisik untuk pencegahan terhadap penyakit degeneratif dan kematian di usia muda. Trait kepribadian dianggap sebagai faktor psikologis kuat dalam identifikasi aktivitas fisik. Penelitian ini adalah survei analitik dengan rancangan cross-sectional pada 33 sampel usia 18-26 tahun yang rutin dan tidak rutin berolahraga. Hasil penelitian menunjukkan bahwa trait kepribadian berkontribusi sebesar 32% (p≤0,05) terhadap aktivitas fisik, khususnya trait ekstraversi, agreeableness, dan openness. Adanya perbedaan signifikan aktivitas fisik dan trait kepribadian antar gender dan rutinitas berolahraga, hal ini disarankan menjadi pertimbangan untuk penelitian lanjutan. Kata Kunci: Trait Kepribadian, Aktivitas Fisik, Gender.

This study aims to describe objectively measured physical activity (PA) in different periods of the day in young adults according to sex, socioeconomic position and during weekdays and weekends. This is a cross-sectional analysis carried out with the participants of the 1993 Pelotas Birth Cohort at 22 years. PA was assessed by triaxial accelerometer. Descriptive analyses were performed presenting the time spent on light PA (LPA) and bouted moderate to vigorous PA (MVPA) in different periods of the day (morning - 6am to 11:59 am, afternoon – 12pm to 7:59 pm and night – 8pm to 11:59pm). The present study included 2,766 individuals (48.2% male and 51.8% female). LPA was higher among women, while bouted MVPA levels were higher among men. The median of  PA was higher on weekdays compared to weekends for all intensities. The bouted MVPA medians in the morning and at night were zero minutes for all days and both sexes. The richest group presented a higher percentage of individuals with zero minutes. PA may vary according to different periods of the day and intensity. The absence of PA practice was markedly influenced by sex and socioeconomic position.
