Physical activity is a critical component of a healthy lifestyle and can lead to improved fitness levels and blood glucose management, as well as decreased HbA1c levels. PURPOSE: The purpose of this study was to determine if there are relationships between cardiorespiratory fitness, muscular strength, muscular endurance, flexibility, body composition, physical activity participation, hemoglobin A1C levels, and motor proficiency in adolescent patients with T1D. METHODS: Pediatric patients with a diagnosis of T1D enrolled in a sports medicine program were invited to participate in this study. Retrospective clinical chart reviews were conducted to determine participant’s sociodemographic and anthropometric measures and most recent HbA1c level. Assessments included cardiorespiratory fitness (VO2max), hand grip strength, push-ups, sit-and-reach, body composition measured by bioelectric impedance analyses, and motor proficiency testing. Participants self-reported weekly PA minutes. A Spearman's correlation was conducted to evaluate the relationship among components of fitness, PA, HbA1c, and motor proficiency. RESULTS: A total of 29 patients (14.03 ± 1.8 years; female, n = 15, 51.7%; white, n = 26, 89.7%) participated in the study. There were five statistically significant relationships: A negative correlation was found between VO2 max and body fat, r(23)=-.473, p = .017; a positive correlation was found between max grip and pushups, r(23) =.421, p = .036; a negative correlation was found between pushups and body fat, r(23) = -.400, p = .047; a negative correlation was found between body fat and BOT standard, r(24) = -.504, p = .009; and a positive correlation was found between physical activity minutes and BOT standard, r(17) = .575, p = .010, p
