Exercise-related self-perception, physical activity and intention to in-person and virtual activities among adolescent girls.

This study aimed (1) to describe the experience of adolescents and adults using FitSpirit asynchronous virtual (V) exercise videos that target adolescent girls, (2) to compare physical activity (PA) levels and exercise-related self-perception variables among groups (2019 in-person [IP], 2021 IP, and 2021 V) of adolescent girls, and (3) to assess the association between the adolescents' PA levels and their exercise-related self-perception in response to IP (pre-pandemic and during pandemic) and V (during pandemic) FitSpirit exercise modes. Regarding the first aim, 28 adolescent girls ([15.5 ​± ​0.

The role of meal timing in appetitive responses to acute exercise in adolescents with and without obesity: A systematic review and meta-analysis.

Physical activity has been shown to improve various aspects of metabolic health and is frequently applied as an intervention in the management and prevention of overweight/obesity. Chrono-exercise can be studied in relation to time of day and timing in relation to a meal, which encompasses chronology and duration of the temporal interval, but the latter has received limited attention to date. This brief review and meta-analysis investigates whether the timing of a meal subsequent to acute exercise, in children and adolescents with and without overweight/obesity, moderates eating behaviour and appetite.

Breaking sedentary behavior among university students: the interest of incorporating cycling desks concurrently with an academic task at light intensity.

: University students experience ≈ 9 h of sitting/day, which may support interventions like active desks. University students ( = 24) Method: Randomized crossover trial aimed to compare effects of sitting (SED), low and moderate-intensity cycling desks (CD; CD) concurrent to an academic task (30-minute video + written exam). Selective visual attention (Tobii Glasses 2) was measured throughout the intervention, and workload (NASA-TLX) and anxiety (POMS-SF) were assessed before and after the video and post-exam.

Feeling safe: a critical look at the effect of neighborhood safety features and perceptions on childhood symptoms of depression.

Background: Physical characteristics and perceptions of an environment can have enduring effects on one's mental health. The present study aimed to determine whether a set of measures of neighborhood safety - independent built environment features, parents' perception of neighborhood safety and community cohesion, and children's perception of neighborhood safety - best related to symptoms of depression in young boys and girls from Montréal, Québec.

Methods: Data were from the Quebec Adipose and Lifestyle Investigation in Youth (QUALITY) cohort.

The impact of exercise timing on energy intake: A systematic review and meta-analysis of diurnal and meal timing effects.

This systematic review and meta-analysis examine the literature (up to August 2nd 2024) on the influence of exercise timing on energy intake in both children and adults. A comprehensive search was conducted using MEDLINE, EMBASE, Cochrane Library, SPORTDiscus, and Web of Science Core Collection, following PRISMA guidelines. The review was registered in Prospero (CRD42024553381) and evaluated using QUADAS-2.

Efficacy of stellate ganglion block in treatment of electrical storm: a systematic review and meta-analysis.

Electrical storm (ES) is a life-threatening condition of recurrent ventricular arrhythmias (VA) in a short period of time. Percutaneous stellate ganglion blockade (SGB) is frequently used - however the efficacy is undefined. The objective of our systematic review was to determine the efficacy of SGB in reducing VA events and mortality among patients with ES.

Adiposity and cardiac autonomic function in children with a family history of obesity.

Purpose: Data on associations between adiposity and heart rate variability (HRV) in prepubertal children are limited. We examined the associations between adiposity indices and HRV, independent of lifestyle behaviors, comparing multiple indicators of adiposity, and explored differences between boys and girls.

Methods: Data stem from 469 participants of the QUALITY cohort (630 children aged 8-10 years with a parental history of obesity).

Adults born preterm have lower peripheral skeletal muscle area and strength.

Prematurity is associated with lower exercise capacity, which relies on the integrity of the cardiovascular, pulmonary, and skeletal muscle systems. Our animal model mimicking prematurity-associated conditions showed altered muscle composition and atrophy in adulthood. This study aimed to compare muscle composition and strength in adults born preterm versus full-term controls.

The association between depressive symptoms and overweight or obesity in prepubertal children: Findings from the QUALITY cohort.

Background: Youth obesity and depression are public health concerns. Although meta-analyses suggest a positive association between those conditions in adults and adolescents, evidence remains unclear in prepubertal children. We examined the bidirectional associations between levels of depressive symptoms and weight status in 8-10-year-old children with a parental history of obesity, over two years, and whether they differ by sex.

Neighbourhood Environments and Lifestyle Behaviours in Adolescents With Type 1 Diabetes.

Objectives: Early prevention strategies are needed to mitigate the high risk of cardiovascular disease in adolescents with type 1 diabetes (T1D). Residential neighbourhood features can promote healthy lifestyle behaviours and reduce cardiovascular risk, but less is known about their role in lifestyle behaviours in adolescents with T1D, and no studies used comparisons to healthy controls.

Methods: We examined associations between residential neighbourhood features and lifestyle behaviours in adolescents with T1D and healthy controls.

Effect of physical activity on olfaction acuity: A systematic review.

Olfaction acuity, which includes detection thresholds, discrimination and identification, appears to decline with age, obesity, and various neurological disorders. Knowing that smell influences energy intake, there is a growing interest in protecting this sense. Physical activity could be a key intervention to counteract the loss of olfaction.

Physiological response during exercise is preserved in children exposed to a suboptimal gestational environment.

Objective: This study investigated whether exposure to suboptimal gestational factors (SGFs) alters mechanical efficiency (ME) and substrate oxidation during rest and exercise in children as a mechanism contributing to obesity.

Methods: Data from the Quebec Adiposity and Lifestyle Investigation in Youth cohort were used. Children aged 8 to 10 years performed an incremental maximal cycling test with indirect calorimetry.

Intensity and Appreciation of Sweet Taste Solutions Are Modulated by High-Intensity Aerobic Exercise in Adolescent Athletic Males.

Purpose: Exercise seems to influence taste, but the effect of exercise on specific tastes is still to be elucidated among youths.

Methods: Athlete boys aged 14-16 years were recruited. Participants (n = 19) ages ranged 14.

The association between parameters of physical activity and olfactory function-the importance of frequency and moderate intensity.

Introduction: Overall physical activity (PA) has been linked to decreased olfactory dysfunction and could improve olfactory function. Additionally, decreased olfactory function can contribute to reduced overall PA levels, given its association with neurodegenerative disorders. This study aims to examine the relationship between specific PA parameters (duration, frequency, intensity) and olfactory function in adults.

Management and outcomes of superficial vein thrombosis: a single-center retrospective study.

Background: Guidelines suggest but cannot recommend the optimal management of superficial vein thrombosis (SVT).

Objectives: To identify the prevalence of asymptomatic deep vein thrombosis (DVT) at the time of SVT diagnosis, and to report the treatment and 3-month complications of patients with only SVT more than 3 cm from deep vein junction (or unknown distance).

Methods: We performed a single-center retrospective review of patients referred to the Ottawa Hospital thrombosis unit with ultrasound (US)-diagnosed SVT, and followed patients with only SVT for 3 months.

Early Lifestyle Determinants of Adiposity Trajectories from Childhood into Late Adolescence.

The aim of this study was to examine associations of childhood physical activity, sedentary behavior, and dietary intake with adiposity trajectories from childhood to adolescence. Quebec Adipose and Lifestyle Investigation in Youth (QUALITY) cohort ( = 630) data from 3 time points (8-10, 10-12, and 15-17 years) for 377 Caucasian children with parental obesity were analyzed. Height and weight, physical activity and sedentary behavior (7-day accelerometry), screen time (self-reported), and dietary intake (three 24-hour diet recalls) were measured.

Children and chrono-exercise: Timing of physical activity on school and weekend days depends on sex and obesity status.

Recommendations for physical activity (PA) typically focus on frequency, intensity, duration, and type, but timing (chrono-exercise) is also important. The objective of this study is to describe when children are active on school and weekend days and explore PA timing across sex and body mass index (BMI) categories. 359 children (53% male), aged 9.

Active time at work following the introduction of a standing and a cycling workstation into worker's office space.

. Active workstations have been proposed to counteract sedentary behavior at work. This study describes office workers' use of and perceptions toward standing and cycling workstations, and assesses whether the two active workstations were sufficient to break sitting time and replace it with 2-4 h of light activity per workday.

Multidimensional school features associated with physical activity among youth at risk of obesity: an exploratory principal component and generalized estimating equation analysis.

Background: Schools may be high-leverage points for the promotion of physical activity (PA), yet little is known about school built and social environments among youth at high risk of obesity.

Purpose: To characterise school built and social environments that may be salient for PA and to examine associations between school PA environments and PA in youth at risk of obesity.

Methods: Data from youth attending 206 schools (314 youth in 2005-2008, and 129 youth in 2008-2010) within the QUALITY cohort study, a longitudinal investigation of youth at high risk of obesity were used.

HAPI Fit: An Exercise Intervention to Improve Peak Aerobic Capacity in Young Adults Born Very Preterm.

Introduction: Individuals born preterm have reduced aerobic capacity, which could be related to impaired organ development. Their capacity to improve aerobic capacity with exercise training could therefore be limited, but this remains unknown. We aimed to test an exercise intervention to improve cardiorespiratory fitness in adults born preterm.

Trajectories of cardiorespiratory fitness from childhood to adolescence: Findings from the QUALITY cohort.

Estimate the shape and number of cardiorespiratory fitness (CRF) trajectories from childhood to adolescence; and verify whether CRF trajectory membership can be predicted by sex, biological maturation, body weight, body composition and physical activity (PA) in childhood. Data from QUALITY were used. Participants attended baseline (8-10 y old,  = 630) and follow-ups 2 years ( = 564) and 7 years ( = 359) after baseline.

Associations of timing of food intake with energy intake, eating behaviour traits and psychosocial factors in adults with overweight and obesity.

Introduction: Whether a late distribution of food intake impacts obesity through increased energy intake remains uncertain and the behavioural characterization of late eating needs to be further investigated. The first objective of this study was to assess the associations between late eating and body mass index (BMI) and total energy intake (TEI), and whether TEI mediates the association between late eating and BMI. The second objective was to assess the associations between late eating and eating behaviour traits or psychosocial factors and whether eating behaviour traits mediate the association between late eating and TEI.
