30-Second Takeaway
- Bone stress injuries and acute injuries cluster in specific sports and groups, arguing for focused screening and prevention.
- Quadriceps recovery after ACLR is slower than traditional timelines, supporting strength-based, individualized RTS decisions.
- Supervised, diagnosis-specific rehab yields larger, durable benefits than generic or unsupervised programs for common shoulder pathology.

Targeted risk management, rehab dosing, and adjuncts in athletic musculoskeletal care
Bone stress injuries are common and female-skewed in Division I athletics
Among 33,190 athlete-years from Pac-12 sports, 1,443 bone stress injuries occurred, with women sustaining most cases. Lower extremity sites dominated (81%), followed by axial (17%) and upper extremity (2%) locations, prioritizing leg-focused surveillance and load management. Average annual risk was 4%, but reached 14.6% in women’s cross country and about 8–10% in several women’s sports. In sex-matched sports, women had higher bone stress injury rates in gymnastics, softball/baseball, basketball, track and field, rowing, and cross country.
Bayesian models forecast individualized quadriceps recovery after ACL reconstruction
Sixty-six Division I athletes completed 317 quadriceps assessments from 1 to 14 months after ACLR, measuring symmetry in peak torque, rate of torque development, and torque steadiness. Bayesian hierarchical B-spline models including graft type and athlete-level random effects yielded the most accurate recovery predictions. After only two early assessments, the model predicted later quadriceps performance with relatively low error for all three metrics. On average, 10 months were needed to reach 90% peak torque symmetry and 12 months to reach 85% RTD symmetry with 95% certainty.
Consensus guidance for abnormal cardiovascular findings in masters athletes
This joint EAPC/ESC and ACC statement addresses masters athletes with atrial fibrillation, brady- and ventricular arrhythmias, coronary atherosclerosis, aortic dilatation, and myocardial fibrosis. It emphasizes that thresholds and treatment algorithms derived from sedentary, symptomatic patients may not be appropriate for highly trained older athletes. The document proposes expert-based frameworks for diagnostic assessment, risk stratification, management, and prognosis, including exercise-induced arrhythmogenic cardiomyopathy. It highlights challenges such as atypical symptom profiles, reluctance to start medications, and interpretation of consumer wearable data.
