The purpose of this review is to describe and discuss the problem of concurrent strength and endurance training. Strength training typically results in increases in muscle mass and muscle atrength, whilst endurance training induces increases in maximal oxygen uptake and metabolic adaptations that lead to an increased exercise capacity. In some situations when strength and endurance training are performed simultaneously an interference in strength development occurs. The article examines new data that offers a potential molecular mechanism that may help explain the inhibition of strength development when strength and endurance training are performed simulataneously.
