Training and physiological characteristics of American and Japanese female track and field athletes.

Background: Intensive training without appropriate recovery can predispose athletes to injury. Balancing these two facets - training and recovery - is crucial for keeping athletes at their highest possible performance level while lowering their risk of training-related injury. Cultural differences may also affect athletes' training and daily routines, but research investigating the effects of cultural background on female track and field athletes is lacking.

Biologics.

Biologics are a growing field that has shown immense promise for the treatment of musculoskeletal conditions both in orthopedic sports medicine and interventional pain management. These procedures utilize injection of supraphysiologic levels of platelets and growth factors to invoke the body's own inflammatory cascade to augment the healing of many bony and soft tissue conditions. While many patients improve with conservative care, there is a need to address the gap between those that improve with rehabilitation alone and those who ultimately require operative management.
