“…In addition, Torii conducted a longitudinal study in a group of high-school-aged long-distance runners, and reported increased BMC and decreased bone turn over markers over a period of 1 year [11]. However, bone parameters differ between sprinters and long distance runners [12], and Bennell et al reported that power athletes had a higher BMC of the lumbar spine than endurance athletes, which was explained by the fact that the load applied to the lumbar spine via foot was higher in power athletes and reached the threshold for bone adaptation [13]. However, changes in BMC, BMD and bone metabolism in female athletes in their late teens have not been fully investigated.…”

With intensive training, bone injuries are a major concern for athletes. To assess bone condition, we often measure bone turnover markers, bone mineral content and density; however, in junior athletes, it is not easy to distinguish changes caused by bone injuries from those caused by growth, because the metabolism is increased in both cases. Moreover, although some studies have examined female endurance athletes, knowledge regarding changes in static and dynamic bone conditions in late teen athletes is limited. In this study, we measured the bone mineral content and density, as well as bone turnover markers, in 40 elite female sprinters in their late teens. Whole body mode dual-energy X-ray absorptiometry was performed to measure bone mineral content and density. Blood samples were collected to determine bone resorption and formation markers at the end of track season in 2016 and during the same period of the following year. Body weight and bone mineral content significantly increased, and tartrate-resistant acid phosphatase type 5b, bone-type alkaline phosphatase, and osteocalcin significantly decreased after a year. Furthermore, the rate of change in bone mineral content was higher in younger athletes, indicating that bone growth approaches completion in the late teen years and that bone metabolism accordingly decreases.
