The benefits of strength training for endurance athletes

Strength Training for Endurance Athletes
Concurrent training is often met with skepticism in endurance sports. However, within the literature, there seems to be a general acceptance on shifting from type I to Type II muscle fibers with predominantly anaerobic and strength based exercise for endurance athletes.

Recent research has illustrated that introducing concurrent heavy strength and endurance training illicit improved time trial in elite cyclists. Changes in rate of force development in these endurance athletes lead to a greater 45 minute time trial result without increases in hypertrophy or body mass. Perhaps indicating, that with more efficient and effective training, including the introduction of strength training, performance gains can be made.
