Diclofenac sodium (Voltaren) reduced exercise-induced injury in human skeletal muscle.

abstract：INTRODUCTION:It is well established that regular physical activity (PA) contributes to lower levels of morbidity and mortality. However, little is known about the stability of very young children's PA habits across seasons and years. The aims of this study were to 1) examine the influence of season and increasing age o...
