Examination of Sex Differences in Energy Availability, Disordered Eating, and Compulsive Exercise Among Male and Female Adolescent Athletes.

Objective: The primary aim of this study was to examine sex differences in energy availability (EA) and its relationships with disordered eating, compulsive exercise, and body mass index (BMI) among adolescent athletes.

Design: Cross-sectional study.

Setting: University hospital pediatric sports medicine center.

Recovery in Hip Range of Motion in Young Flexibility Athletes 1 Year After Periacetabular Osteotomy.

Periacetabular Osteotomy (PAO) is a well-established surgical intervention for the treatment of hip dysplasia. Our primary objective was to assess whether a group of young flexibility athletes who underwent PAO for hip dysplasia recovered their pre-operative hip range of motion (ROM) within 1 year of surgery. Our secondary objective was to compare hip ROM recovery between a group of young flexibility athletes and a group of non-flexibility athletes who underwent PAO for hip dysplasia.

Association of Grit With Postoperative Knee Outcomes and Physical Function After ACL Reconstruction in Adolescent Athletes.

Background: Grit is the disposition to strive for long-term goals despite setbacks and challenges. Given the lengthy, arduous process of rehabilitation after anterior cruciate ligament reconstruction (ACLR), an athlete's grit may predict postoperative outcomes across time.

Purpose/hypothesis: The primary aim of the study was to evaluate the relationships between baseline (preoperative) grit and postoperative knee outcomes across the year after ACLR among adolescents.

Bone Health in Young Athletes: a Narrative Review of the Recent Literature.

Purpose Of Review: The aim of this review is to discuss the most recent published scientific evidence regarding bone health in the pediatric athlete.

Recent Findings: Pediatric athletes commonly suffer from overuse injuries to the physes and apophyses, as well as bone stress injuries, for which magnetic resonance imaging grading of the severity of injuries may be useful in guiding return to sport. Adolescent athletes, particularly those who train indoors and during the winter season, are at risk for vitamin D deficiency, which has important implications for bone mineral density.

Changes in Quality of Life, Sleep, and Physical Activity During COVID-19: A Longitudinal Study of Adolescent Athletes.

Context: The abrupt cessation of school and sport participation during the COVID-19 pandemic may have negative implications for adolescent mental health.

Objectives: To (1) compare mental, physical, and social health and behaviors during pandemic-related stay-at-home mandates with the same measures collected 1 to 2 years earlier and (2) evaluate the relationships between physical activity and sleep during the pandemic and changes in anxiety, fatigue, and peer relationships between assessment times.

Design: Cohort study.

Differences in Training and Health Characteristics Between Trail Ultrarunners and Shorter Distance Runners.

Introduction: The primary aim of the study was to compare select training and health characteristics between ultramarathon and shorter distance runners participating in a trail race series.

Methods: A questionnaire was sent to all participants who signed up for a trail race series, including distances of 10 km, half marathon, 50 km, 80.5 km (50 mi), and 100 km.

Incidental Os Odontoideum in an Adolescent Athlete With Sports-Related Concussion.

Sports-related concussion (SRC) is a frequent injury in the adolescent population with presentation including a wide array of signs and symptoms. There are no universally agreed upon guidelines for when to pursue advanced imaging, such as magnetic resonance imaging (MRI), in the workup of SRCs in the adolescent population. Our experience indicates that MRI rarely contributes to management.

Training volume recommendations and psychosocial outcomes in adolescent athletes.

Objectives: Researchers have recommended that youth athletes limit their practice volume to the number of hours/week that they are old in years. We examined sport perceptions, burnout, anxiety, and depressive symptoms among youth athletes who did and did not report playing more hours/week of organized sports than their age.

Methods: Uninjured athletes aged 13-18 years old completed questionnaires documenting demographics, sport participation volume, health and injury history, depressive symptoms, anxiety, burnout, and sport perceptions during a pre-participation physical examination.

Socioeconomic status and injury history in adolescent athletes: Lower family affluence is associated with a history of concussion.

Background: While healthcare and health outcome disparities have been studied across a variety of different injuries, their relation to concussion incidence and management are relatively understudied.

Aim: The aim of this study was to evaluate the association between history of concussion or musculoskeletal injury, and family affluence and/or school-level measures of socioeconomic status.

Methods: We conducted a cross-sectional study of adolescent athletes in a local school district.

Sport specialization, sleep, fatigue, and psychosocial ratings: do highly specialized athletes differ from their less specialized peers?

Objectives: To determine if sleep quality, fatigue, anxiety, depressive symptoms, or perceptions of sport participation differ between high-, moderate-, and low-specialized high school athletes with or without prior injuries.

Methods: During pre-participation physical examinations (PPE), high school athletes completed questionnaires on sport specialization level, history of time-loss orthopedic injury, perceptions of sport participation, as well as sleep quality (Pittsburgh Sleep Quality Index (PSQI)), fatigue, anxiety, and depressive symptoms (Patient-Reported Outcomes Measurement Information System (PROMIS®)). Athletes were grouped according to sport specialization level and history of prior time-loss orthopedic injury.

Presence and Perceptions of Menstrual Dysfunction and Associated Quality of Life Measures Among High School Female Athletes.

Context: Adolescent female athletes are at risk for menstrual dysfunction in the setting of exercise and low energy availability. Education regarding menstrual dysfunction and its associated consequences is important to promote athlete wellbeing.

Objective: The primary aim was to determine the prevalence and characteristics of female athletes who believed that losing their period was a normal response to high training demands.

Patient expectations and perceived social support related to return to sport after anterior cruciate ligament reconstruction in adolescent athletes.

Objective: Examine the relationship between pre-operative competitive status and return to sport expectations post-operatively among adolescents undergoing ACL reconstruction. Assess the association between perceived levels of social support and doubts in returning to sport after ACL reconstruction.

Design: Cross-sectional.

Family Affluence Relationship to Sports Specialization in Youth Athletes.

Our objective was to examine the association between participant-reported family affluence and sport specialization level. We conducted a cross-sectional investigation of adolescent athletes. Specifically, participants completed a level of sport specialization (low/moderate/high) questionnaire and the Family Affluence Scale.

Exercise effects on arterial stiffness and heart health in children with excess weight: The SMART RCT.

Introduction: Childhood obesity and inactivity are associated with cardiovascular risk. Evidence is limited for exercise effects on arterial health in children.

Methods: One hundred and seventy-five inactive children with overweight or obesity (8-11 years, ≥85th percentile BMI, 61% female, 87% Black, 73% with obesity) were randomized to an 8-month daily after-school aerobic exercise program (40 min/day, n = 90) or a sedentary control condition (n = 85).
