The current study examined binge eating behaviors among first-year undergraduate students over the academic year (September 2019, November 2019, January 2020, March 2020), and if between and within person effects of physical activity and sleep impact binge eating behaviours during times of higher-and lower-stress (n=394, Mage=18.6). Participants completed online surveys of moderate and vigorous exercise, hours and quality of sleep, and binge eating behaviours four times over the academic year. Results of multilevel models revealed relatively stable binge eating scores across the academic year. We did not find evidence of robust associations between exercise and sleep and binge eating behaviors during times of high and low stress over the academic year. Large increases in vigorous physical activity may be effective in reducing binge eating behaviors among women. These findings suggest that the effect of exercise on binge eating behaviours may be smaller than previous research suggests and that targeted exercise intervention is needed to see meaningful changes in binge eating behaviors.

The authors performed a clustered randomized controlled trial to investigate the effects of an aerobic and a cognitively demanding exercise intervention on executive functions in primary-school-age children compared with the regular physical education program (N = 856). They hypothesized that both exercise interventions would facilitate executive functioning, with stronger effects for the cognitively demanding exercise group. The interventions were provided four times per week for 14 weeks. Linear mixed models were conducted on posttest neurocognitive function measures with baseline level as covariate. No differences were found between the exercise interventions and the control group for any of the measures. Independently of group, dose of moderate to vigorous physical activity was positively related to verbal working memory and attention abilities. This study showed that physical exercise interventions did not enhance executive functioning in children. Exposure to moderate to vigorous physical activity is a crucial aspect of the relationship between physical activity and executive functioning.

The objective isto establish emotional state changes among female students during the academic year regarding available physical activity.Material & methods: the study involved 65 first year femalestudents of medical college at Danylo Halytskyi Lviv National Medical University. To achieve the tasks set the study relied on the following methods: analysis and synthesis of scientific and technical literature, pedagogical observation, methods of mathematical statistics (t-Student test for independent samples), SAN method.Results: no reliable differences found when comparing indicators of activity and mood at the beginning and end of the academic year. The obtained results of the survey indicate medium and high evaluationof SAN categories at low levels of physical activity.Conclusions: state of health, activity and mood levelswere rated with middle and high scoresbyfemale students. SAN evaluation dynamics has been lowering during the academic year, and the activity level of female students was significantly lower than that ofstate of health as well as mood. The resulting index of activity level as emotional characteristic largely reflects low physical activity of female students.

Daily Activity Patterns

The purpose of this study was to examine the effects of participation in an aerobic exercise intervention on daily activity occurring outside of the structured exercise sessions. Participants were randomized into one of the following 4 conditions: 1) No-exercise, 2) Low volume, low intensity exercise (LVLI), 3) High volume, low intensity exercise (HVLI), 4) Low volume, high intensity (LVHI). Physical activity was measured over 7 days with an accelerometer at baseline and during week 8 of the intervention. Activity was defined as: sedentary behaviour (SED; < 100 counts/minute), light physical activity (LPA; 100 to 1951 counts/minute), moderate-to-vigorous physical activity (MVPA; ≥1952 counts/minute), and total physical activity (TPA; LPA + MVPA). Activity was quantified as average total minutes per day of each SED, LPA, MVPA, and TPA. A one-way ANOVA was used to determine if time spent in SED, LPA, MVPA, and TPA changed from baseline to week 8. Seventy-one participants (No-exercise; n=12, LVLI n=17, HVLI n=24, LVHI; n=18,) with a mean age of 54 y and waist circumference of 110 cm completed 8 weeks of the intervention. There were no significant differences in SED, LPA, MVPA, or TPA between groups at baseline. There was no significant change in SED, LPA, MVPA, or TPA at week 8 compared to baseline (p>0.05). Similarly, there were no significant differences in activity variables between exercise conditions. Our observations suggest that daily activity patterns do not change with the implementation of an exercise intervention in men and women.

This study examined the effect of exercise training on sleep duration and quality and bidirectional day-to-day relationships between physical activity (PA) and sleep. Fourteen inactive men with obesity (49.2±7.9 years, BMI 34.9±2.8 kg/m²) completed a baseline visit, eight-week aerobic exercise intervention, and one-month post-intervention follow-up. PA and sleep were assessed continuously throughout the study duration using wrist-worn accelerometry. Generalised estimating equations (GEE) were used to examine associations between PA and sleep. Sleep duration increased from 5.2h at baseline to 6.6h during the intervention period and 6.5h at one-month post-intervention follow-up (p<0.001). Bi-directional associations showed that higher overall activity volume and moderate-to-vigorous physical activity (MVPA) were associated with earlier sleep onset time (p<0.05). Later timing of sleep onset was associated with lower overall volume of activity, most active continuous 30 minutes (M30CONT), and MVPA (p<0.05). Higher overall activity volume, M30CONT, and MVPA predicted more wake after sleep onset (WASO) (p<0.001), whereas greater WASO was associated with higher overall volume of activity, M30CONT, and MVPA (p<0.001). An aerobic exercise intervention increased usual sleep duration. Day-to-day, more PA predicted earlier sleep onset, but worse sleep quality and vice versa. Novelty: • Greater levels of physical activity in the day were associated with an earlier sleep onset time that night, whereas a later timing of sleep onset was associated with lower physical activity the next day in men with obesity • Higher physical activity levels were associated with worse sleep quality, and vice versa

ObjectivesPhysical activity may be important in deterring the obesity epidemic. This study aimed to determine whether objectively measured physical activity in first year of upper secondary high school predicted changes in body composition over 2 years of follow-up in a cohort of Norwegian adolescents (n=431).DesignA longitudinal study of adolescents (mean age of 16 (SD 0.4) at baseline, 60.3% girls) participating in the Fit Futures studies 1 (2010–2011) and 2 (2012–2013).SettingAll eight upper secondary high schools in two municipalities in Northern Norway.ParticipantsStudents participating in both studies and under the age of 18 at baseline and with valid measurement of physical activity at baseline and body composition in both surveys.Primary and secondary outcomesChange in objectively measured body mass index and waist circumference and change in dual-energy X-ray absorptiometry measured fat mass index, lean mass index (LMI) and appendicular LMI (aLMI) between baseline and follow-up.ResultsAt baseline, boys had significantly higher physical activity volume (p=0.01) and spent on average of 6.4 (95% CI 2.1 to 10.6) more minutes in moderate-to-vigorous physical activity (MVPA) than girls (p<0.01). In girls, multivariate regression analyses showed that more sedentary time was negatively associated with changes in LMI (p<0.01) and aLMI (p<0.05), whereas more light activity had opposite effects on these measures (p<0.01 and p<0.05, respectively). No significant associations between measures of baseline physical activity and changes in body composition parameters were observed in boys.ConclusionsIn this cohort of Norwegian adolescents, sedentary and light physical activity was associated with changes in LMI and aLMI in girls, but not boys. Minutes spent in MVPA in first year of upper secondary high school was not associated with changes in measures of body composition in neither sex after 2 years.

Objective: To estimate the influence of socioeconomic factors on the variation in time spent by university students on physical activity after the first academic year. Methods: Quantitative longitudinal study of 348 full-time university students aged 16-25 years from the capital of Mato Grosso, Brazil. Change in time spent on moderate and vigorous physical activity was assessed in minutes per week through the short version of the International Physical Activity Questionnaire (IPAQ). The following independent variables were analyzed: gender, age, race/skin color, economic class, students’ housemates and field of study. Multinomial regression analysis was used to check for associations between physical activity time variation in tertiles and the independent variables. Results: The overall change in median physical activity time in one year was -90.0 minutes/week. Students of higher socioeconomic status maintained the same physical activity time, while those in other socioeconomic classes showed a decrease in such time after the first year at university. After adjustments, lower economic class (OR=2.85; 95%CI= 1.26-6.43) and living in a shared house (OR=2.84; 95%CI= 1.26-6.38) were associated with decrease in time spent on physical activity. Conclusion: There was a decrease in time spent on physical activity among students belonging to the lower economic classes who lived in a shared house after the first year at university.

Regular physical activity (PA) is an important part of the treatment of several medical conditions, including overweight and obesity, in which there may be a weakened appetite control. Eating behaviour traits influence weight control and may be different in active and sedentary subjects. This paper reports the relationships between the time spent in sedentary behaviour and physical activity (PA) of different intensity, and eating behaviour traits in young, healthy adults. Additionally, it reports the results of a six-month-long, randomized, controlled trial to examine the effect of an exercise intervention on eating behaviour traits. A total of 139 young (22.06 ± 2.26 years) healthy adults (68.35% women) with a Body Mass Index (BMI) of 24.95 ± 4.57 kg/m2 were enrolled. Baseline assessments of habitual PA were made using wrist-worn triaxial accelerometers; eating behaviour traits were examined via the self-reported questionnaires: Binge Eating, Three-Factor Eating Questionnaire-R18 and Control of Eating Questionnaire. The subjects were then randomly assigned to one of three groups: control (usual lifestyle), moderate-intensity exercise (aerobic and resistance training 3¨C4 days/week at a heart rate equivalent to 60% of the heart rate reserve (HRres) for the aerobic component, and at 50% of the 1 repetition maximum (RM) for the resistance component), or vigorous-intensity exercise (the same training but at 80% HRres for half of the aerobic training, and 70% RM for the resistance training). At baseline, sedentary behaviour was inversely associated with binge eating (r = −0.181, p < 0.05) and with uncontrolled eating (r = −0.286, p = 0.001). Moderate PA (MPA) was inversely associated with craving control (r = −0.188, p < 0.05). Moderate-to-vigorous PA (MVPA) was directly associated with binge eating (r = 0.302, p < 0.001) and uncontrolled eating (r = 0.346, p < 0.001), and inversely associated with craving control (r = −0.170, p < 0.015). Overall, PA was directly associated with binge eating (r = 0.275, p = 0.001), uncontrolled eating (r = 0.321, p < 0.001) and emotional eating (r = 0.204, p < 0.05). Additionally, only emotional eating was modified by the intervention, increasing in the vigorous-intensity exercise group (p < 0.05). In summary, we observed that time spent in sedentary behaviour/PA of different intensity is associated with eating behaviour traits, especially binge eating in young adults. In contrast, the six-month exercise intervention did not lead to appreciable changes in eating behaviour traits.

AbstractTestosterone is a male sex hormone and low circulating testosterone levels are associated with various health disorders in men. Obesity results in reduced circulating testosterone levels in men. Previously, we demonstrated that lifestyle modifications (combination of aerobic exercise and dietary modification) increase circulating testosterone levels in overweight/obese men. However, the effect of regular aerobic exercise on serum testosterone levels remains unclear. The purpose of this study was to investigate the effect of a 12-week aerobic exercise intervention on circulating testosterone levels in normal-weight and overweight/obese men. Sixteen normal-weight men and twenty-eight overweight/obese men completed a 12-week aerobic exercise intervention. Before and after the intervention, we measured serum total testosterone, free testosterone, and bioavailable testosterone levels, and categorized the physical activity levels (light, moderate, or vigorous) in all participants. At baseline, serum total testosterone, free testosterone, and bioavailable testosterone levels were significantly lower in overweight/obese men than in normal-weight men (all p<0.01). After the 12-week aerobic exercise intervention, serum total testosterone, free testosterone, and bioavailable testosterone levels significantly increased in overweight/obese men (p<0.01). In addition, stepwise multivariable linear regression analysis revealed the increase in vigorous physical activity was independently associated with increased serum total testosterone levels (β=0.47, p=0.011). We demonstrated that a 12-week aerobic exercise intervention increased serum total testosterone, free testosterone, and bioavailable testosterone levels in overweight/obese men. We suggest that an increase in vigorous physical activity increased circulating testosterone levels in overweight/obese men.

Abstract Previous studies show that physical activity is beneficial for emotional well-being. This study extends prior research by examining whether engagement in physical activity moderates the association between daily stressor severity and daily emotional well-being. We used data from the second wave of the National Study of Daily Experiences, a sub-project of the Midlife in the United States (MIDUS) study. Respondents (N = 1,851; ages 33 to84) reported their daily experiences across eight consecutive days. Multilevel models explored concurrent and lagged interaction effects between daily stressor severity and physical activity on negative and positive affect and whether these associations differed by age. Physical activity was measured by engagement in vigorous physical activity for at least 30 minutes. Results showed significant interactions between stressor severity and physical activity on same-day negative and positive affect. Specifically, stressor severity was associated with smaller elevation in daily negative affect on physically active days (b = 0.08, p &lt; 0.001) compared to non-active days (b = 0.11, p &lt; 0.001). Reductions in daily positive affect were greater on physically inactive days (b = -0.11, p &lt; 0.001) compared to active days (b = -0.08, p &lt; 0.001). These associations did not differ by age, but additional findings revealed that stressor severity was associated with greater elevation in negative affect among younger respondents (b = 0.12, p &lt; 0.001) than older adults (b = 0.10, p &lt; 0.001). These results highlight the importance of engagement in physical activity for emotional well-being under stressful situations in daily context.
