This study provides the first insights into fast and slow muscle fiber transcriptome dynamics with lifelong endurance exercise. The fast fibers were more responsive to exercise with divergent transcriptome signatures among young exercisers (growth and metabolic), lifelong exercisers (metabolic), and old healthy nonexercisers (stress).

Investigators from Shaanxi Normal University in China studied the impact of increasing backpack load on the gait of adolescents during stair descent. Sixteen healthy male students (age = 12.9 ± 0.6 years) were required to descend the stairs in 4 loaded conditions. The kinematic, kinetic, and EMG data were collected synchronously and gait parameters, especially indicators of balance control, were analyzed.

Ankle osteoarthritis severely impacts patients’ mental and physical quality of life. Besides total ankle replacement and ankle arthrodesis, ankle distraction has been shown to be a promising alternative. The primary aim of this systematic literature review and meta-analysis was to determine the annual revision rates (ARRs) after ankle distraction.

Competitive athletes are always looking for an extra edge to help improve performance. According to a new study by Concordia researchers published in the journal Physical Activity and Nutrition, they can find one in the common cranberry. Cranberries have the highest polyphenol and antioxidant capacity among fruits and vegetables and may protect against exercise-induced free radical production, consequently improving performance.

Researchers from the Department of Orthopaedics at the Nemours Children’s Hospital Delaware (Wilmington, DE) wanted to understand the change in dynamic foot posture in children with cerebral palsy. They were able to track 33 children (54 limbs) who completed 16.9 evaluations from an initial age of 2.9 (±0.7) yrs to 18.6 (±1.7) yrs. They found that early valgus foot…
